1 Remembering and Understanding: 28 40
Exhibit memory of previously learned material by recalling
facts, terms, basic concepts and answers. Demonstrate
understanding of facts and ideas by organizing,
comparing, translating, interpreting, giving descriptions
and stating main ideas.
2 Applying: 21 30
Solve problems to new situations by applying acquired
knowledge, facts, techniques and rules in a different way.
3 Analysing, Evaluating and Creating: 21 30
Examine and break information into parts by identifying
motives or causes. Make inferences and find evidence to
support generalizations. Present and defend opinions by
making judgments about information, validity of ideas or
quality of work based on a set of criteria.
Compile information together in a different way by
combining elements in a new pattern or proposing
alternative solutions.
