First of all, talk about textbooks.
(1) position and function: the basic nature of inequality. Beijing normal university printing plate, eighth grade junior high school mathematics, chapter 1, section 2. Before that, students have learned inequality relations, which paved the way for the transition to this section. The basic nature of inequality plays a connecting role in teaching materials. Learning it is based on the basic properties of equality, which is an important theoretical basis for students to learn linear inequalities and solutions of linear inequalities in the future, and an important foundation and necessary skills for students to learn in the future.
(2) Teaching objectives:
According to the above teaching material analysis, considering the psychological characteristics of students' existing cognitive structure, I set the following teaching objectives:
1, knowledge goal: master the basic properties of inequality.
2. Ability goal: We can accurately use the three properties of inequality to simplify the deformation of inequality and cultivate students' observation and analysis ability.
3. Emotional goal: to cultivate students' dialectical materialism.
(C), the focus and difficulty of teaching
Based on the curriculum standards and thorough understanding of teaching materials, I have established the following teaching priorities and difficulties.
Emphasis: master and apply the basic properties of inequality.
Difficulty: the discovery process of the basic properties of inequality.
According to the characteristics of this class and the level of students' knowledge and ability, this teaching method is adopted.
Second, the method of speaking and learning: adopt the learning method of cooperation and communication.
Third, teaching methods: heuristic explanation.
Fourth, talk about procedures.
