Teaching goal is the soul of classroom teaching, which has the functions of overall situation, guidance and adjustment. Mathematics curriculum standard divides teaching objectives into three dimensions: knowledge and skills, process and method, emotion, attitude and values, among which process and method are divided into mathematical thinking and problem solving, and points out that these four objectives are an organic whole. Among them, the development of mathematical thinking, emotional attitude and values can not be separated from the learning of knowledge and skills, which must be conducive to the realization of other goals. However, when setting teaching objectives, many teachers lack a deep understanding of the teaching objectives and are too innovative and perfect, which leads to many embarrassment. Now let's talk about my understanding of three-dimensional goals:

First, the connotation of three-dimensional goals (a) knowledge and skills (one-dimensional)

The so-called knowledge goal mainly refers to subject knowledge (indirect knowledge in textbooks) and tacit knowledge (life experience and social experience, etc. ) and the information knowledge that students want to learn (knowledge obtained through various information channels).

Examples of knowledge target expression (pay attention to subject, verb, condition and expression degree): through learning, we know that animals also have emotions; Understand the basic properties of scores through learning.

The so-called skills refer to the activities formed through practice and necessary to complete a certain task. Skill objectives can be divided into four categories:

The first is basic skills. Such as reading, writing and computing skills. Example of goal expression: Through study, you can read the text correctly and emotionally.

The second is intellectual skills. Such as perception, memory, imagination and thinking, reasoning and other skills. Example of goal expression: through learning, learn to study and understand the object by scientific methods of experiment and reasoning.

The third is motor skills. Such as painting, doing exercises, playing ball games, etc. Example of goal expression: through learning, master the basic essentials of forward roll and backward roll.
