Bloom and others divide teaching objectives into three areas: cognition, emotion and action, and the objectives in each area are divided into several levels from low to high. The goal of cognitive field includes six levels: knowledge, understanding, application, analysis, synthesis and evaluation. The education law points out that questions are both simple and complex, and questions are asked according to the learning objectives.

Knowledge: Being able to find and identify received information from long-term memory.

Examples can describe the law of conservation of energy.

Understanding: the ability to grasp the meaning of knowledge materials. It can be manifested in three forms:

First, transformation is to express what you have learned in your own words.

An example of an abstract concept, the translation of ancient Chinese or foreign languages, etc.

Second, interpretation means to explain or summarize a piece of information.

Summarize the general idea of the article with examples.

Third, infer the development trend.

For example, ask students to judge how a ball placed on a smooth surface will move when it is pushed.

Application: apply what you have learned to new situations.

For example, use the learned electrical knowledge to install circuit lights.

Analysis: the ability to break down a complex whole material into its components and understand the connections between them.

Analyze narrative elements with examples.

Synthesis: recombine the parts of the learned knowledge to form a new knowledge whole.

For example, through a series of experimental observations, guide students to summarize the laws and formulas of free fall.

Evaluation: the ability to make value judgments on materials (such as papers, novels, poems, research reports, etc.). ).

For example, you can judge the correctness of the geometry problems you have proved.

Expand the level of the other two data areas:

First, the emotional field (active field)

The teaching objectives in the field of emotion, headed by Dr Krathwohl, were put forward in 1964 and divided into five levels:

1, accepted

Step 2 show

3. Form value

4. Organizational value system

5. Individualization of value system

Second, the field of motor skills (psychomotor field)

Bloom only realized the existence of the field of motor skills when he founded the educational goal, but did not formulate a specific goal level. 1972 Simpson EJ puts forward that the teaching objectives in the field of motor skills are divided into seven levels:

1, perception

Step 2 lead the trend

3. Under the guidance of reflection.

4, mechanical action

5. Complex explicit reflection

Step 6 adapt

7. Innovation and innovation
