10.1 Formulating learning objectives  (Page 5/6)

 Page 5 / 6

Bloom’s taxonomy:

In its original form, Bloom’s Taxonomy of educational objectives referred to forms of cognition or thinking, which were divided into the six levels (Bloom, et al., 1956). Table 5 summarizes the levels, and offers two kinds of examples—simple ones based on the children’s story Goldilocks and the Three Bear s, and complex ones more typical of goals and objectives used in classrooms. The levels form a loose hierarchy from simple to complex thinking, at least when applied to some subjects and topics. When planning for these subjects it can therefore be helpful not only for insuring diversity among learning objectives, but also for sequencing materials. In learning about geography, for example, it may sometimes make sense to begin with information about specific places or societies (knowledge and comprehension), and work gradually toward comparisons and assessments among the places or societies (analysis and synthesis).

 Type or level of learning Simple example Classroom example Knowledge : recall of information, whether it is simple or complex in nature “Name three things that Goldilocks did in the house of the three bears.” “List all of the planets of the solar system.” “State five key features of life in the middle ages.” Comprehension : grasping the meaning of information, by interpreting it or translating it from one form to another “Explain why Goldilocks preferred the little bear’s chair.” “Convert the following arithmetic word problem to a mathematical equation.” “Describe how plants contribute to the welfare of animal life.” Application : using information in new, concrete situations “Predict some of the things Goldilocks might have used if she had entered your house.” “Illustrate how positive reinforcement might affect the behavior of a pet dog.” “Use examples from the plot to illustrate the theme of novel.” Analysis : breaking information into its components to understand its structure “Select the part of Goldilocks and the Three Bears where you think Goldilocks felt most comfortable.” “Compare the behavior of domestic dogs with the behavior of wolves.” “Diagram the effects of weather patterns on plant metabolism.” Synthesis : putting parts of information together into a coherent whole “Tell how the story would have been different if it had been three fishes.” “Design an experiment to test the effects of gravity on root growth.” “Write an account of how humans would be different if life had originated on Mars instead of Earth.” Evaluation : judging the value of information for a particular purpose “Justify this statement: Goldilocks was a bad girl.” “Appraise the relevance of the novel for modern life.” “Assess the value of information processing theory for planning instruction.”

Such a sequence does not work well, however, for all possible topics or subjects. To learn certain topics in mathematics, for example, students may sometimes need to start with general ideas (like “What does it mean to multiply?”) than with specific facts (like “How much is 4 x 6?”) (Egan, 2005). At other times, though, the reverse sequence may be preferable. Whatever the case, a taxonomy of cognitive objectives, like Bloom’s, can help to remind teachers to set a variety of objectives and to avoid relying excessively on just one level, such as simple recall of factual knowledge (Notar, et al., 2004).

what is Nano technology ?
write examples of Nano molecule?
Bob
The nanotechnology is as new science, to scale nanometric
brayan
nanotechnology is the study, desing, synthesis, manipulation and application of materials and functional systems through control of matter at nanoscale
Damian
Is there any normative that regulates the use of silver nanoparticles?
what king of growth are you checking .?
Renato
What fields keep nano created devices from performing or assimulating ? Magnetic fields ? Are do they assimilate ?
why we need to study biomolecules, molecular biology in nanotechnology?
?
Kyle
yes I'm doing my masters in nanotechnology, we are being studying all these domains as well..
why?
what school?
Kyle
biomolecules are e building blocks of every organics and inorganic materials.
Joe
anyone know any internet site where one can find nanotechnology papers?
research.net
kanaga
sciencedirect big data base
Ernesto
Introduction about quantum dots in nanotechnology
what does nano mean?
nano basically means 10^(-9). nanometer is a unit to measure length.
Bharti
do you think it's worthwhile in the long term to study the effects and possibilities of nanotechnology on viral treatment?
absolutely yes
Daniel
how to know photocatalytic properties of tio2 nanoparticles...what to do now
it is a goid question and i want to know the answer as well
Maciej
Abigail
for teaching engĺish at school how nano technology help us
Anassong
Do somebody tell me a best nano engineering book for beginners?
there is no specific books for beginners but there is book called principle of nanotechnology
NANO
what is fullerene does it is used to make bukky balls
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
Tarell
what is the Synthesis, properties,and applications of carbon nano chemistry
Mostly, they use nano carbon for electronics and for materials to be strengthened.
Virgil
is Bucky paper clear?
CYNTHIA
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
NANO
so some one know about replacing silicon atom with phosphorous in semiconductors device?
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Harper
Do you know which machine is used to that process?
s.
how to fabricate graphene ink ?
for screen printed electrodes ?
SUYASH
What is lattice structure?
of graphene you mean?
Ebrahim
or in general
Ebrahim
in general
s.
Graphene has a hexagonal structure
