初中化学酸、碱、盐知识具有起点低、落点高、知识点多、涉及面广、综合性强、易混乱、易忘记、应用更难的特点.通过教学实践发现,在学习酸碱盐之前,学生学习化学的兴趣和能力水平差异不是很大,但学习酸碱盐之后,就产生很大的差异,不少同学开始对化学学习束手无策,导致成绩一落千丈.所以说,酸碱盐是初中化学教学的重点和难点,教学成绩优与劣的分化点.酸碱盐知识的教学质量不高已将成为制衡初中化学教学质量提高的瓶颈.初中化学教师如何才能教会、引导学生学好这部分知识呢?以下是本人的一些教学经验和教学实践,仅供参考.一、教材资源的挖掘
Junior high school chemistry acid, alkali, salt knowledge with a low starting point, high landing point, knowledge points, involving a wide range of comprehensive strong, easy to chaos, easy to forget, more difficult to use features found through teaching practice, learning acid-base salt Before, students’ interest in learning chemistry and ability level is not very different, but after learning acid-base salt, there are a lot of differences, many students began to know nothing about chemical learning, resulting in plummeted results.Therefore, acid-base salt is junior high school The emphasis and difficulty of chemistry teaching, the excellent and poor teaching achievement.The teaching quality of acid-base salt knowledge has become the bottleneck to check the chemistry teaching quality of junior middle school.How can junior middle school chemistry teachers teach and guide students to learn this part of knowledge? The following is some of my teaching experience and teaching practice, for reference purposes only.
