化学复习课是新课的继续,要通过知识重组,使学生将所学的化学知识和技能系统化、条理化。化学复习课特别是板块知识的复习,教师要精心设计复习内容,让学生站在一定高度,通过自主学习,重新审视和梳理所学内容,主动建构知识网络。一、提纲引导式自主学习教学模式化学反应类型、原理及规律如复分解反应、质量守恒定律、元素周期律、原电池、化学平衡等内容,教师可设计成复习提纲,引导学生自己去建构复习内容。课例1.复习复分解反应及发生条件(1)先让学生各举两例书写下列反应的化学方程式:①酸与金属氧化物;②酸和碱;③酸和盐;④碱和非金属氧化物;⑤碱和盐;⑥盐和盐。
Chemistry review is the continuation of the new lesson, through the reorganization of knowledge so that students learn the chemical knowledge and skills systematized and organized. In particular, the chemistry review class is a review of the knowledge of the plate. Teachers should carefully design the review contents so that the students can stand at a certain height and re-examine and sort out what they have learned through self-study to construct knowledge networks. First, the outline of the guided self-paced learning mode of chemical reaction type, principles and laws such as metathesis reaction, the law of conservation of mass, the elemental periodic law, the original battery, chemical equilibrium and so on, teachers can design review outline, guide students to construct review content . Lesson 1. Review of Metathesis and Conditions (1) Students are asked to write the chemical equations for the following reactions in two separate cases: Acid and Metal Oxides Acid and Alkali Acid and Salts Alkali and Nonmetal Oxidation ⑤ base and salt; ⑥ salt and salt.
