Bloom's educational goals are divided into cognitive field, emotional field and motor skill field.

First, cognitive goals:

The goal of cognitive domain refers to the result of cognition, including six levels: cognition, understanding, application, analysis, synthesis and evaluation.

Second, the emotional 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;

2. reaction;

3. Form values;

4. Organizational value system;

5. Personalized value system;

Third, the field of motor skills:

The teaching goal of sports skills refers to the goals that students should achieve in sports skills after the expected teaching, including perception, imitation, operation, accuracy, coherence and habituation.

Bloom's teaching goal divides the mastery of all knowledge points into six levels:

1, memory: can find and identify the received information from long-term memory.

2. Understanding: After getting the information, you can express your meaning in your own words.

3. Application: Information can be executed or used under given circumstances.

4. Analysis: Decompose the information to determine the relationship between each part and between each part and the whole.

5. Evaluation: Be able to make judgments based on the information obtained.

6. Creation: It can be reorganized into a new model or structure according to the obtained information.

The levels that training can reach are memory layer, understanding layer and application layer, while the analysis layer, evaluation layer and creation layer are generally not achieved through training activities. Understanding the six levels of Bloom's teaching objectives is very important for curriculum design and development, which embodies the professionalism of curriculum design and development.
