【教材分析】本节课是建立在学生学完了科学所有课程后,面临中考的第一轮复习。酸碱盐部分的知识因其知识点多、反应多、知识点之间的联系紧密,而成为初中科学教学中的重难点,而和酸碱盐有关的考题又在中考中占了很重要的地位。【学生分析】学生虽然对酸碱盐的概念及其相关的性质已有一定的认识,但对于灵活掌握酸碱盐相互间的化学变化,就显得比较薄弱。【设计思路】 【Textbook Analysis】 This lesson is based on the students completed the science of all courses, facing the exam of the first round of review. Knowledge of acid-base salt because of its knowledge more, more reaction, the connection between the knowledge points close, and became the junior high school science teaching heavy difficulty, and the acid-base salt test questions and in the examination accounted for very important status. Students Analysis Although the concept of acid-base salt and its related properties have some understanding, but for the flexible grasp of the chemical changes between acid-base salts, it is relatively weak. 【Design ideas】
