W.E.N.N ? Sir Ian McKellen Has Prostate Cancer

Veteran actor Sir Ian Mckellen has revealed he has been fighting prostate cancer ?for six or seven years?.
The Lord of the Rings icon feared the worst when a biopsy discovered cancerous cells, but the 73-year-old Brit has not undergone treatment for the disease and instead has regular tests to ensure it hasn?t spread.
He tells Britain?s Daily Mirror, ?You do gulp when you hear the news. It?s like when you go for an HIV test, you go, ?Argh, is this the end of the road?? They say you have cancer of the prostate and then that you can have it zapped.
?You can have it snipped but you are not a candidate for that. You are ?waitful watching?. I?ve had it for six or seven years, when you have got it you monitor it and you have to be careful it doesn?t spread. But if it is contained in the prostate, it?s no big deal.
?Many, many men die from it but it?s one of the cancers that is totally treatable so I have ?waitful watching?. I am examined regularly and it?s just contained, it?s not spreading. I?ve not had any treatment.
?You are told what the situation is: you can have an operation but there is no point me having an operation because there is no need for it. They are concerned about the cancer spreading outside the prostate. If it doesn?t you are fine. How do you know if it is spreading? You keep being tested.?
And despite cloudy vision and a hearing problem, Sir Ian insists he still feels ?absolutely fine? ? thanks to regular exercise.
He adds, ?I just got hearing aids, I am going to have a cataract removed from my eyes, I am having an implant in my mouth, I am dealing with the prostate? (But) I am absolutely fine, thank you very much!
?I am lucky, I don?t have aches and pains. I do Pilates regularly which is a series of stretching exercises and I recommend it to anyone of my age because the temptation is not to exercise when you get older. Well, you should. I always walk up the escalator on the Tube (subway) and I live in a house with a lot of stairs. That?s good exercise but you need more.
?The wonderful thing about modern medicine is that so many of these complaints that used to signify old age and decline can be coped with.?

Novo bets on high-price niche for obesity drug

LONDON (Reuters) - Denmark's Novo Nordisk is sizing up a high-price niche market for its drug liraglutide as a weight-loss treatment, with the United States the prime opportunity.

The premium-price approach could turn it into a multibillion-dollar-a-year product, the company believes.

Novo is studying the injected drug - already on the market as a treatment for type-2 diabetes under the brand name Victoza - as a therapy for the seriously obese, with pivotal clinical trial results due in the first half of next year.

While some in the industry are sceptical about using so-called GLP-1 diabetes drugs such as liraglutide to fight obesity, Novo's Chief Science Officer Mads Krogsgaard Thomsen believes the approach can offer cost-effective benefits.

Glucagon-like peptide-1, or GLP-1, drugs work by stimulating insulin release when glucose levels become too high. Their ability to induce weight loss is an added benefit, since type-2 diabetes is linked to obesity.

What is more, the willingness of the U.S. Food and Drug Administration to license new obesity pills from Vivus and Arena Pharmaceuticals last summer shows the door is open to such new medicines, Thomsen said.

"It's positive. More physicians are now knowledgeable that pharmacotherapy can make a difference and the political establishment in the U.S. now knows that behavior change alone is not enough," he said in an interview in London.

More than a third of American adults, or some 100 million people, are obese and the figure is rising fast, posing a growing threat to the nation's health.

Among this population group, liraglutide may help the severely obese, including those with related problems like interrupted breathing during sleep and pre-diabetes, who might otherwise receive stomach surgery.

"We are not going out to treat the 100 million ... We see this as solving a problem in a niche of maybe a few million patients," Thomsen said.

"If you took one million patients and gave them liraglutide at 3.0 milligrams (a day) at the U.S. price that would be a $6 billion market."

When used in diabetes as Victoza, liraglutide is given at daily doses of either 1.2 or 1.8 mg. Novo is betting on a higher dose to produce greater weight-loss in the obese. A key unknown is whether this will produce unacceptable side effects - and Thomsen admits this makes it something of a "joker" in the company's line-up of new products.

The main adverse effect of Victoza is nausea in some patients, although this is not strong enough in itself to account for the weight loss seen with the drug and Thomsen does not see nausea as a hurdle to regulatory approval.

More worrying, would be any evidence that high-dose liraglutide is linked to pancreatitis.

Given the high safety bar required for a new obesity drug, analysts are currently divided as to whether liraglutide will make it for weight loss - especially given past disappointments with diet drugs such as Sanofi's Acomplia.

If all goes according to plan, however, Novo aims to file for approval at the end of next year, implying a potential U.S. launch in late 2014 or early 2015 for a product that would add a new string to the bow of the world's biggest maker of insulin.

Year's Best Meteor Shower Peaks This Week

Stargazers are about to get their annual celestial treat: A bright meteor shower, the Geminids, will grace skies worldwide this week, with a peak in activity on Thursday (Dec. 13).

No telescope or binoculars are required to see the show ? just use your bare eyes. The moon will set before the meteors come out to play around 10 p.m. local time, meaning the sky should be nice and dark for optimal viewing. There could be as many as 100 to 150 meteors an hour to gape at, for those patient enough to spend a few hours in a dark area and let their eyes adapt to starlight.

The Geminids, unusually among meteor showers, are the leftovers of an asteroid (most showers originate with comets). They are caused when rubble from the asteroid hits Earth's atmosphere, lighting a path through the sky as it burns up.

The fact that the Geminid-causing debris comes from an asteroid and not a comet makes the particles denser and more durable than the typical cometary particles that make up other showers, said NASA's Bill Cooke. [Graphic: How Meteor Showers Work]

"It makes them stronger. They can survive lower in the atmosphere," said Cooke, the lead for NASA's Meteoroid Environments Office at the Marshall Space Flight Center in Huntsville, Ala.

A typical Geminid particle, he said, is about 1/25 of an inch (1 millimeter) in size and can survive as low as 35 miles in altitude. Yet the full story of how these particles came to be is shrouded in mystery.

Collision one of several theories

For skywatchers looking up, the Geminids appear to emanate from a point in the sky in the constellation Gemini.

But more properly, the origins of this shower come from the debris of an asteroidcalled 3200 Phaethon. As Earth runs into the debris stream during the planet's orbit around the sun, some of the particles burn up in Earth's atmosphere.

A stream of dust broke off this 3-mile-wide (4.8 kilometers) asteroid several centuries ago, likely from a collision with another space rock, Cooke said. The stream remained in space for centuries, out of the firing range of Earth's orbit.

Then, around the 1830s, the gravity of Jupiter, which shifted the stream over the centuries, perturbed the rocky stream enough that the Earth ran into it. More disturbances from Jupiter have pushed the stream closer to Earth, resulting in more meteors.

The collision theory is one of several hypotheses for the Geminids' beginnings. Some astronomers say the stream began when Phaethon broke off from the asteroid Pallas, but the orbits of the meteoroid particles don't neatly fit with the theory.

The term "meteoroid" refers to rocks in space that have not entered Earth's atmosphere. When they hit the atmosphere in a blaze of light, they're referred to as "meteors," then "meteorites" if they reach the ground.

Another hypothesis: Phaethon sheds debris when it gets close to the sun in its orbit, and is blasted by the sun's heat. Observations from NASA's twin STEREO spacecraftgave credence to the idea in 2009, but the amount of dust seen was not enough to keep the stream replenished over time.

Regardless of the Geminids' origins, Cooke said the single biggest threat to the shower is not the amount of dust, but its orbit.

If Jupiter's gravity interferes with the stream in a certain way, it's possible the debris could be diverted away from Earth. But that's not expected to happen any time soon, Cooke added.

Meteor showers more popular

Cooke said Twitter, Facebook and other forms of social media are making the public more aware of when meteor showers occur.

Also, television and other mainstream media outlets tend to broadcast meteor events. When Cooke spoke to SPACE.com on Friday (Dec. 7), he was fielding several media calls about a fireball spotted over Texas.

Cooke said he welcomes the interest, but also tries to educate those who speak with him.

"One of the biggest misconceptions is a lot of people think that the [Geminid] meteor ? always the bright ones ? will land near them. That's not true," Cooke said.

"That's an illusion. It's very rare, exceedingly rare, for a meteorite to land near an individual, and the Geminids won't produce meteorites. They will not make it to the ground. People don't have to worry about getting hit by falling Geminids."

Biological Science - enabler modestia

Normal 0 false false false EN-US X-NONE X-NONE

B.Ed OPTIONAL COURSE

BIOLOGICAL SCIENCE ? I

UNIT I Place, Goals and Objectives of Biology

Biology in the school curriculum ? its claims for inclusion ? Interdisciplinary approaches in the school curriculum ? Various branches related to Life Science.

Goals and objectives of teaching Biology with reference to Bloom?s taxonomy- Cognitive, Affective and Psychomotor Domains. Aims of teaching Biology at different levels ? Primary, Secondary and Higher Secondary.

Biology in the school curriculum

??????????? Biology is a natural science concerned with the study of life and living organisms, including their structure, function, growth, origin, evolution, distribution, and taxonomy. Biology is a vast subject containing many subdivisions, topics, and disciplines. Among the most important topics are five unifying principles that can be said to be the fundamental axioms of modern biology:

  1. Cells are the basic unit of life
  2. New species and inherited traits are the product of evolution
  3. Genes are the basic unit of heredity
  4. An organism regulates its internal environment to maintain a stable and constant condition
  5. Living organisms consume and transform energy.
??????????? Sub disciplines of biology are recognized on the basis of the scale at which organisms are studied and the methods used to study them: biochemistry examines the rudimentary chemistry of life; molecular biology studies the complex interactions of systems of biological molecules; cellular biology examines the basic building block of all life, the cell; physiology examines the physical and chemical functions of the tissues, organs, and organ systems of an organism; and ecology examines how various organisms interact and associate with their environment.

What is science?

??????????? The word "science" probably brings to mind many different pictures: a fat textbook, white lab coats and microscopes, an astronomer peering through a telescope, a naturalist in the rainforest, Einstein's equations scribbled on a chalkboard, the launch of the space shuttle, bubbling beakers ?. All of those images reflect some aspect of science, but none of them provides a full picture because science has so many facets:

  • Science is both a body of knowledge and a process. In school, science may sometimes seem like a collection of isolated and static facts listed in a textbook, but that's only a small part of the story. Just as importantly, science is also a process of discovery that allows us to link isolated facts into coherent and comprehensive understandings of the natural world.
  • Science is exciting. Science is a way of discovering what's in the universe and how those things work today, how they worked in the past, and how they are likely to work in the future. Scientists are motivated by the thrill of seeing or figuring out something that no one has before.
  • Science is useful. The knowledge generated by science is powerful and reliable. It can be used to develop new technologies, treat diseases, and deal with many other sorts of problems.
  • Science is ongoing. Science is continually refining and expanding our knowledge of the universe, and as it does, it leads to new questions for future investigation. Science will never be "finished."
  • Science is a global human endeavor. People all over the world participate in the process of science. And you can too!

Science is complex and multi-faceted, but the most important characteristics of science are straightforward:

  • Science focuses exclusively on the natural world, and does not deal with supernatural explanations.
  • Science is a way of learning about what is in the natural world, how the natural world works, and how the natural world got to be the way it is. It is not simply a collection of facts; rather it is a path to understanding.
  • Scientists work in many different ways, but all science relies on testing ideas by figuring out what expectations are generated by an idea and making observations to find out whether those expectations hold true.
  • Accepted scientific ideas are reliable because they have been subjected to rigorous testing, but as new evidence is acquired and new perspectives emerge these ideas can be revised.
  • Science is a community endeavor. It relies on a system of checks and balances, which helps ensure that science moves in the direction of greater accuracy and understanding. This system is facilitated by diversity within the scientific community, which offers a broad range of perspectives on scientific ideas.

??????????? Too many, science may seem like an arcane, ivory-towered institution ? but that impression is based on a misunderstanding of science. In fact:

  • Science affects your life everyday in all sorts of different ways.
  • Science can be fun and is accessible to everyone.
  • You can apply an understanding of how science works to your everyday life.
  • Anyone can become a scientist ? of the amateur or professional variety.

Definitions of Science

????????? sci?ence

1.????? A branch of knowledge or study dealing with a body of facts or truths systematically arranged and showing the operation of general laws: the mathematical sciences.

2. Systematic knowledge of the physical or material world gained through observation ?? ????????????????????????????????????????????and experimentation.

4. systematized knowledge in general.

5. Knowledge, as of facts or principles; knowledge gained by systematic study.

6. A particular branch of knowledge.

7. Skill, especially reflecting a precise application of facts or principles; proficiency.

Definitions by goal and process

?2. The organized body of knowledge that is derived from such observations and that can be verified or tested by further investigation.

?3. any specific branch of this general body of knowledge, such as biology, physics, geology, or astronomy.

Academic Press Dictionary of Science & Technology

??????????? Science is an intellectual activity carried on by humans that is designed to discover information about the natural world in which humans live and to discover the ways in which this information can be organized into meaningful patterns. A primary aim of science is to collect facts (data). An ultimate purpose of science is to discern the order that exists between and amongst the various facts.

??????????? Science involves more than the gaining of knowledge. It is the systematic and organized inquiry into the natural world and its phenomena. Science is about gaining a deeper and often useful understanding of the world.

The Nature of Normal Science

??????????? Normal science is the practice of gaining knowledge by using some paradigm. It therefore has a perspective, common rules, facts, and problems. Its task is to solidify, reify, and articulate the paradigm; quantify its predictions, extend it to new areas, and to develop the technology needed. It rejects the approbations of the lay. It does not attempt to answer all problems. It uses facts considered revealing to solve problems considered acute by the paradigm. It is to articulate accepted phenomena. Problems must be challenging but not hopeless. Frequently the paradigm and its rules are tacit, they cannot be articulated. The adequacy of a paradigm is judged by peers not lay.

??????????? Normal science is the finding of previously unpredicted phenomena and showing how that phenomenon is explainable with the existing paradigm. Finding unexplainable phenomena is not science; anyone can be capable of not explaining something. Brain damage helps enormously. Normal science does not produce new phenomena; it articulates those that the paradigm supplies. Extending the paradigm (showing how the paradigm explains previously unexplainable events) is mopping up and is where most scientists spend their lives.

??????????? A paradigm gains status because it handles problems that practitioners feel are important - not because it handles all problems.

??????????? 1. Empirical work to articulate paradigm or theory. Determinants of physical constants / quantitative laws / determination of way to apply paradigm to new situation.

??????????? 2. Facts without intrinsic interest which can be compared to predictions from the paradigm.

??????????? 3. Class of facts that the paradigm has shown to be revealing of nature. To desert the paradigm is to cease practicing the science it defines. The task is to explain current problems with rules such that the majority of past findings are consistent, somewhat like a judge trying to be consistent with precedent, or trying to minimize sum of squared differences when determining a regression line.

Fact

? ???????? ?1. ?Something that actually exists; reality; truth: Your fears have no basis in fact.

??????????? ?2. Something known to exist or to have happened: Space travel is now a fact.

3. A truth known by actual experience or observation; something known to be true: ???Scientists gather facts about plant growth.

4. Something said to be true or supposed to have happened: The facts given by the witness are highly questionable.

5. Law often, facts an actual or alleged event or circumstance, as distinguished from its legal effect or consequence. Compare question of fact, question of law.

There are four types of fact. The first type of fact cannot be proved by the experiments as we wish. We have to see this fact when it happens. The second type of fact can be seen and shown at any time. The third type of fact is the generalization i.e. one fact is associating with another fact. The fourth type is a theory but it is treated as fact because of the evidences to prove the theory.

BIOLOGY AS A SCIENCE

??????????? When we say science we know pretty well that includes not only physics and chemistry but also Biology. We can give three reasons to prove that Biology is also a science. They are:

1.????? Biology possesses the characters of other branches of science like practical, experiments, data and utility for the life. We know that all the three branches of science possess all these qualities. Biology also gives the same benefits to the society as the other branches.

2.????? Biology gives a complete and notable knowledge like other branches of science. We know that physics deals with instruments and equipments, chemistry deals with chemical substances and their combinations and biology deals with living organisms. So it gives a complete notable knowledge about living organisms.

3.????? Biology gives extra training in the scientific method. We know that scientific method is a method followed by scientists to develop science. While physics and chemistry gives training to the pupil in this method, Biology is expected to give extra training in this method. This is because it deals with living organisms and they have to face complex problems in their life. The pupils are expected to adopt the scientific method in order to find how the living organisms overcome the complex problems. So they get extra training in the scientific method by studying Biology. Because of these three reasons Biology is considered as science along with other branches of science. ?

GOALS AND OBJECTIVES OF TEACHING BIOLOGY WITH REFERENCE TO BLOOM?S TAXONOMY

Benjamin Bloom's Taxonomy of Learning Domains - Cognitive, Affective, Psychomotor Domains - design and evaluation toolkit for training and learning

??????????? Bloom's Taxonomy, (in full: 'Bloom's Taxonomy of Learning Domains', or strictly speaking: Bloom's 'Taxonomy Of Educational Objectives') was initially (the first part) published in 1956 under the leadership of American academic and educational expert Dr Benjamin S Bloom. 'Bloom's Taxonomy' was originally created in and for an academic context, (the development commencing in 1948), when Benjamin Bloom chaired a committee of educational psychologists, based in American education, whose aim was to develop a system of categories of learning behaviour to assist in the design and assessment of educational learning. Bloom's Taxonomy has since been expanded over many years by Bloom and other contributors (notably Anderson and Krathwhol as recently as 2001, whose theories extend Bloom's work to far more complex levels than are explained here, and which are more relevant to the field of academic education than to corporate training and development).

??????????? Most corporate trainers and HR professionals, coaches and teachers, will benefit significantly by simply understanding the basics of Bloom's Taxonomy, as featured below. (If you want to know more, there is a vast amount of?related reading and references, listed at the end of this summary explanation.)

Bloom's Taxonomy was primarily created for academic education; however it is relevant to all types of learning.

??????????? Interestingly, at the outset, Bloom believed that education should focus on 'mastery' of subjects and the promotion of higher forms of thinking, rather than a utilitarian approach to simply transferring facts. Bloom demonstrated decades ago that most teaching tended to be focused on fact-transfer and information recall - the lowest level of training - rather than true meaningful personal development, and this remains a central challenge for educators and trainers in modern times. Much corporate training is also limited to non-participative, unfeeling knowledge-transfer, (all those stultifying boring PowerPoint presentations...), which is reason alone to consider the breadth and depth approach exemplified in Bloom's model.

You might find it helpful now to see the?Bloom Taxonomy overview. Did you realize there were all these potential dimensions to training and learning?

??????????? Benjamin S Bloom (1913-99) attained degrees at Pennsylvania State University in 1935. He joined the Department of Education at the University of Chicago in 1940 and attained a PhD in Education in 1942, during which time he specialized in examining. Here he met his mentor Ralph Tyler with whom he first began to develop his ideas for developing a system (or 'taxonomy') of specifications to enable educational training and learning objectives to be planned and measured properly - improving the effectiveness of developing 'mastery' instead of simply transferring facts for mindless recall. Bloom continued to develop the Learning Taxonomy model through the 1960's, and was appointed Charles H Swift Distinguished Service Professor at Chicago in 1970. He served as adviser on education to several overseas governments including of Israel and India.

??????????? Bloom's (and his colleagues') initial attention was focused on the?'Cognitive Domain', which was the first published part of Bloom's Taxonomy, featured in the publication: 'Taxonomy Of Educational Objectives: Handbook 1, The Cognitive Domain' (Bloom, Engelhart, Furst, Hill, Krathwohl, 1956).

??????????? The 'Taxonomy of Educational Objectives: Handbook II, The Affective Domain' (Bloom, Masia, Krathwohl) as the title implies, deals with the detail of the second domain, the?'Affective Domain', and was published in 1964.

??????????? Various people suggested detail for the third?'Psychomotor Domain', which explains why this domain detail varies in different representations of the complete Bloom Taxonomy. The three most popularly referenced versions of the Psychomotor Domain seem to be those of???? RH Dave?(1967/70),?EJ Simpson (1966/72), and?AJ Harrow?(1972).

??????????? As such 'Bloom's Taxonomy' describes the three-domain structure, within which the detail may vary, especially for the third domain.

??????????? Bloom's Taxonomy has therefore since 1956 provided a basis for ideas which have been used (and developed) around the world by academics, educators, teachers and trainers, for the preparation of learning evaluation materials, and also provided the platform for the complete 'Bloom's Taxonomy' (including the detail for the third 'Psychomotor Domain') as we see it today. Collectively these concepts which make up the whole Bloom Taxonomy continue to be useful and very relevant to the planning and design of: school, college and university education, adult and corporate training courses, teaching and lesson plans, and learning materials; they also serve as a template for the evaluation of: training, teaching, learning and development, within every aspect of education and industry.

Training or learning design and evaluation need not cover all aspects of the Taxonomy - just make sure there is coverage of the aspects that are appropriate.

??????????? As such, if in doubt about your training aims - check what's possible, and perhaps required, by referring to Bloom's Taxonomy.

Explanation of bloom's taxonomy

??????????? First, don't be put off by the language or the apparent complexity of Bloom's Taxonomy - at this basic level it's a relatively simple and logical model.

??????????? Taxonomy?means 'a set of classification principles', or 'structure', and?Domain?simply means 'category'. Bloom and his colleagues were academics, looking at learning as a behavioural science, and writing for other academics, which is why they never called it 'Bloom's Learning Structure', which would perhaps have made more sense to people in the business world. (Interestingly this example of the use of technical language provides a helpful lesson in learning itself, namely, if you want to get an idea across to people, you should try to use language that your audience will easily recognize and understand.)

??????????? Bloom's Taxonomy underpins the classical 'Knowledge, Attitude, Skills' structure of learning method and evaluation, and aside from the even simpler?Kirkpatrick learning evaluation model, Bloom's Taxonomy of Learning Domains remains the most widely used system of its kind in education particularly, and also industry and corporate training. It's easy to see why, because it is such a simple, clear and effective model, both for explanation and application of learning objectives, teaching and training methods, and measurement of learning outcomes.

??????????? Bloom's Taxonomy provides an excellent structure for planning, designing, assessing and evaluating training and learning effectiveness. The model also serves as a sort of?checklist, by which you can ensure that training is planned to deliver all the necessary development for students, trainees or learners, and a template by which you can assess the validity and coverage of any existing training, be it a course, a curriculum, or an entire training and development programme for a large organization.

??????????? It is fascinating that Bloom's Taxonomy model (1956/64) and?Kirkpatrick's learning evaluation model (1959) remain classical reference models and tools into the 21st century. This is because concepts such as Bloom's Taxonomy, Kirkpatrick's model,?Maslow's Hierarchy of Needs,?Mcgregor's XY Theory, The?SWOT analysis?model, and?Berne's Transactional Analysis theory, to name a few other examples, are timeless, and as such will always be relevant to the understanding and development of people and organizations. Bloom?s taxonomy definitions

??????????? Bloom's Taxonomy model is in three parts, or 'overlapping domains'. Again, Bloom used rather academic language, but the meanings are simple to understand:

  1. Cognitive domain?(intellectual capability, i.e.,?knowledge, or?'think')
  2. Affective domain?(feelings, emotions and behaviour, i.e.,?attitude, or?'feel')
  3. Psychomotor domain?(manual and physical skills, i.e.,?skills, or?'do')

??????????? This has given rise to the obvious short-hand variations on the theme which summaries the three domains; for example, Skills-Knowledge-Attitude, KAS, Do-Think-Feel, etc.

??????????? Various people have since built on Bloom's work, notably in the third domain, the 'psychomotor' or skills, which Bloom originally identified in a broad sense, but which he never fully detailed. This was apparently because Bloom and his colleagues felt that the academic environment held insufficient expertise to analyze and create a suitable reliable structure for the physical ability 'Psychomotor' domain. While this might seem strange, such caution is not uncommon among expert and highly specialized academics - they strive for accuracy as well as innovation. In Bloom's case it is as well that he left a few gaps for others to complete the detail; the model seems to have benefited from having several different contributors fill in the detail over the years, such as Anderson, Krathwhol, Masia, Simpson, Harrow and Dave (these last three having each developed versions of the third 'Psychomotor' domain).

??????????? In each of the three domains Bloom's Taxonomy is based on the premise that the categories are ordered in degree of difficulty.?An important premise of Bloom's Taxonomy is that each category (or 'level') must be mastered before progressing to the next. As such the categories within each domain are levels of learning development, and these levels increase in difficulty.

??????????? The simple matrix structure enables a checklist or template to be constructed for the design of learning programmes, training courses, lesson plans, etc. Effective learning - especially in organizations, where training is to be converted into organizational results - should arguably cover all the levels of each of the domains, where relevant to the situation and the learner.

??????????? The learner should benefit from development of knowledge and intellect (Cognitive Domain); attitude and beliefs (Affective Domain); and the ability to put physical and bodily skills into effect - to act (Psychomotor Domain).

??????????? Here's a really simple adapted 'at-a-glance' representation of Bloom's Taxonomy. The definitions are intended to be simple modern day language, to assist explanation and understanding. This simple overview can help you (and others) to understand and explain the taxonomy. Refer back to it when considering and getting to grips with the detailed structures - this overview helps to clarify and distinguish the levels.

??????????? For the more precise original Bloom Taxonomy terminology and definitions see the more detailed domain structures beneath this at-a-glance model. It's helpful at this point to consider also the ?conscious competence' learning stages model, which provides a useful perspective for all three domains, and the concept of developing competence by stages in sequence.

6. Evaluate (assess, judge in relational terms)

N.B. In the Cognitive Domain, levels 5 and 6, Synthesis and Evaluation, were subsequently inverted by Anderson and Krathwhol in 2001. Anderson and Krathwhol also developed a complex two-dimensional extension of the Bloom Taxonomy, which is not explained here. If you want to learn more about the bleeding edge of academic educational learning and evaluation there is a list of further references below. For most mortals in teaching and training what's on this page is probably enough to make a start, and a big difference.

??????????????? Note also that the Psychomotor Domain featured above is based on the domain detail established by RH Dave (who was a student of Bloom) in 1967 (conference paper) and 1970 (book). The Dave model is the simplest and generally easiest to apply in the corporate development environment. Alternative Psychomotor Domains structures have been suggested by others, notably?Harrow and Simpson's models detailed below. I urge you explore the?Simpson?and?Harrow?Psychomotor Domain alternatives - especially for the development of children and young people, and for developing skills in adults that take people out of their comfort zones. This is because the Simpson and Harrow models offer different emotional perspectives and advantages, which are useful for certain learning situations, and which do not appear so obviously in the structure of the Dave model.

??????????? Bloom's Taxonomy in more detailed structure follows, with more formal terminology and definitions. Refer back to the?Bloom Taxonomy overview?any time you need to refresh or clarify your perception of the model. It is normal to find that the extra detail can initially cloud the basic structure - which is actually quite simple - so it's helpful to keep the simple overview to hand.

?Bloom?s taxonomy learning domains - detailed structures

Bloom's Taxonomy 1956 Cognitive Domain is as follows. An adjusted model was produced by Anderson and Krathwhol in 2001 in which the levels five and six (synthesis and evaluation) were inverted (reference: Anderson & Krathwhol, A Taxonomy for Learning, Teaching, and Assessing: A Revision of Bloom's Taxonomy of Educational Objectives, 2001). This is why you will see different versions of this Cognitive Domain model. Debate continues as to the order of levels five and six, which is interesting given that Bloom's Taxonomy states that the levels must be mastered in order.

??????????? In my humble opinion it's possible to argue either case (Synthesis then Evaluation, or vice-versa) depending on the circumstances and the precise criteria stated or represented in the levels concerned, plus the extent of 'creative thinking' and 'strategic authority' attributed to or expected at the 'Synthesis' level. In short - pick the order which suits your situation.

??????????? Based on the 'Taxonomy Of Educational Objectives: Handbook 1, The Cognitive Domain' (Bloom, Engelhart, Furst, Hill, Krathwhol) 1956. This table is adapted and reproduced with permission from Allyn & Bacon, Boston USA, being the publishers and copyright owners of 'Taxonomy Of Educational Objectives' (Bloom et al 1956).

Note that levels 5 and 6, Synthesis and Evaluation, were subsequently inverted by Anderson and Krathwhol in 2001, on which point:

??????????? The question of the order of Synthesis and Evaluation is dependent upon the extent of strategic expectation and authority that is built into each, which depends on your situation. Hence it is possible to make a case for Bloom's original order shown above, or Anderson and Krathwhol version of 2001 (which simply inverts levels 5 and 6).

??????????? The above version is the original, and according to the examples and assumptions presented in the above matrix, is perfectly appropriate and logical. I also personally believe the above order to be appropriate for?corporate and industrial training and development?if?'Evaluation'?is taken to represent?executive or strategic assessment and decision-making, which is effectively at the pinnacle of the corporate intellect-set.

??????????? The inversion of Synthesis and Evaluation carries a risk unless it is properly qualified. This is because the highest skill level absolutely must involve?strategic evaluation; effective management - especially of large activities or organizations - relies on strategic evaluation. And clearly,?strategic evaluation is by implication included in the 'Evaluation' category.

??????????? I would also argue that in order to evaluate properly and strategically, we need first to have learned and experienced the execution of the strategies (ie, to have completed the synthesis step) that we intend to evaluate.

??????????? However, you should feel free to invert levels 5 and 6 if warranted by your own particular circumstances, particularly if your interpretation of 'Evaluation' is non-strategic, and not linked to decision-making. Changing the order of the levels is warranted if local circumstances alter the degree of difficulty. Remember, the taxonomy is based in the premise that the degree of difficulty increases through the levels - people need to learn to walk before they can run - it's that simple. So, if your situation causes 'Synthesis' to be more challenging than 'Evaluation', then change the order of the levels accordingly (i.e., invert 5 and 6 like Anderson and Krathwhol did), so that you train people in the correct order.

??????????? Bloom's Taxonomy second domain, the Affective Domain, was detailed by Bloom, Krathwhol and Masia in 1964 (Taxonomy of Educational Objectives: Volume II, The Affective Domain. Bloom, Krathwhol and Masia.) Bloom's theory advocates this structure and sequence for developing attitude - also now commonly expressed in the modern field of personal development as 'beliefs'. Again, as with the other domains, the Affective Domain detail provides a framework for teaching, training, assessing and evaluating the effectiveness of training and lesson design and delivery, and also the retention by and affect upon the learner or trainee.

Ideas And Tips For Home Improvement Projects | Fitness Training ...

In home improvement, many resources exist for those who are both novices and old pros. There are a ton of ways you can get information; there are videos and books to available in stores and online. The following information will present to you the most useful information regarding home improvement.

Before painting a room, cover each electrical outlet with foil. The foil protects while you paint and is much easier to work with than tape. That makes cleanup much easier. Just let paint dry before removing the foil and recycling it for other purposes.

TIP! When hiring a contractor, be sure to have in writing the exact costs of the home improvements. It should also have guarantees on what work will be completed on what timeline, and a payment plan.

Avoid contractors who offer bonuses for cash payments, as they are involved in illegal acts. Paying with cash is risky. If you must pay with cash you can protect yourself by getting a signed copy of the contract prior to any work or payment and of course, get a written receipt for any cash you do give them.

The time you spend prepping your space before painting can save you both time and money on your home improvement project. If you are painting rooms in your home, you should always cover the furniture before you begin painting. Paint splattered on furniture can ruin it. Cover your furniture with sheets or cloths to avoid any splatters or drips from the paint.

Don't get too crazy with color when painting. Neutral colors will help you portray more space. Installing larger baseboards will make a room appear larger. Both of these options can be done for a low price and will improve the look of your home.

TIP! Check for low areas of your property, especially near the house foundation. Consider adding some compacted soil to these areas so your home isn't damanged from erosion.

Without much decoration and personality, simple lamp shades are sometimes very boring. Get cheap stencils at the crafts store, an ink pad or acrylic paint, and try dabbing the designs around the shade. This will give your rooms some personality, taking away from the reality of how boring an ordinary lamp shade can be.

Bold prints will certainly liven up any space. Animal prints are a good choice as well. Leopard print pillows or zebra striped cushions are a good choice, as are posters and wall art.

Before you attempt to sell your home, you need to ensure that each individual space within the home as a clear purpose. Whether the room in question is an office or a den, its accessories and furniture should make its usage clear. When you do this, each room in the house looks more comforting and comfortable to live in. This makes the home more attractive and likely to sell faster.

It is important to turn the breaker off when doing any electrical work. Touching live wires without having disconnected the power supply can cause electrocution and even death.

Close the blinds to block your carpet and floors from sunlight. This is because the sun will change the color of your carpet and it will fade in the spots where the sun light shines. Open drapes when the sun is lower in the sky, or strategically place your furniture to block some of the light.

Think about hiring a professional when you are working on home improvements. they will help you get the best look at the best price for your budget. Hire a professional to help you get on track in deciding which projects you are willing to tackle first.

TIP! Seal cracks and openings to save on heating bills, as well as preventing bugs from entering your home. All you need is simple caulk, which is applied around your windows, along baseboards and any other areas that could have small openings to the outside.

After reading these guidelines, you are now ready to tackle your home improvement to-do list. A vast amount of information is available and you should try to learn how best to apply it. With this in mind, you can refine your own techniques and goals to create the home of your dreams.

Corvette Auction Preview: 1968 L88 Corvette at RM's Arizona Auction

It?s not often that someone has the chance to buy a genuine piece of automotive history, with complete documentation since new to prove its heritage.

But that?s what bidders at the upcoming RM Auction in Phoenix, Arizona will have a chance to do on January 18, 2013.

Being offered is one of only 80 L88 Corvettes manufactured in 1968, and RM can trace the history of the most powerful Corvette of the muscle car era back to the original owner.

The car features the legendary 427 L88 engine that produced a massive 540-hp and delivered 0-60 times of 4.2 seconds and 0-100 runs under 10 seconds. This example earned a Bloomington Gold certification in 1988 and is an NCRS Top Flight Award winner. L88 expert Tim Thorpe recently gave the engine compartment a $16,000 refreshening.

It goes without saying that this is a numbers matching car, one of the few L88s left that still has its original motor.

The L88 was the crown jewel in the ?big block? Mark IV engine program that began with a 396 V8 in 1965. Next came the 427 in 1966, basically a 396 with a larger 4.25 bore, an 11:1 compression ratio, and an advertised 425-hp.

Chevrolet wasn?t satisfied with that, however, and came up with the L71 in 1967, a 427 with three two-barrel carburetors that made 435-hp. Another engine came in the form of the L89, which featured aluminum heads and was essentially an option for the optional L71 engine. That same year, Chevy went one better with the L88, based on the 427 but with 12.5:1 compression and a single Holley four-barrel carburetor that delivered 560-hp.

With a new body style being offered in 1968, the L88 returned, with 80 people opting for that engine despite its nearly $1,000 price tag.

One of those buyers was the father of Carl Schettler of Salt Lake City, Utah, who gave it to his son as a college graduation present. As required for all L88s, the car has the M22 ?rock crusher? four-speed manual transmission, the J50/J56 heavy duty power four-wheel disc brakes, a 4:11 positraction rear end, the F41 special purpose suspension, an N11 off-road exhaust, and a transistorized ignition. The car listed for $5,589, confirmed by both the original order for the car and the tank sticker. The original owner?s manual is also still with the car.

Schettler sold the car to a college friend in 1971, then got it back sometime between 1973 and 1974. Over the next three years, the car passed through three owners in Alaska before Bob Fattore sold it in 1987 to ?Corvette Mike? Vietro. The current owners bought it in 2008 and have continued to remain careful stewards of this Corvette, one of only 216 L88s made from 1967 to 1969.

In the 1988 Bloomington Special Collection, the car earned 99.0 points out of 100. NCRS documentation from Oct. 23, 2012 verifies the authenticity of the tank sticker.

The black interior was restored to original in 1987 by Nabers Brothers.

RM?s Arizona auction will be held on the grounds of the Arizona Biltmore Resort and Spa on Saturday, January 18th. Visit www.rmauctions.com for more information and to view selected lots.
