一、问题的提出高中化学教学的难度相对初中化学教学有比较大的提升,在高中化学课堂教学中,对习题的研究所占的的份额比较大,对教学的影响也较大,所以对习题进行研究的效率的高低在很大程度上决定着化学教学的成效。如何在有限的课堂教学时间内,最大限度地提高教学效率,尤其是如何在对习题的教学中进行教学方式的变革,改变教学过程中学生过分依赖教师的讲解、过于强调接受学习、死记硬背、机械训练的现状,变单一的师生互动为多向的生生互动,关注学生的个体差异,创设能引导学生主动参与的教学环境,激发学生的学习积极性,使每个学生都能得到充分的发展,寻求创新教学之路,就成为一个重
First, the problem raised The difficulty of high school chemistry teaching relative to junior high school chemistry teaching has been greatly improved in high school chemistry classroom teaching, the share of the study of exercises relatively large, the impact of teaching is also large, so the exercise The level of efficiency in conducting research largely determines the effectiveness of chemistry teaching. How to improve the teaching efficiency to a maximum extent in the limited time of classroom teaching, especially how to change the teaching methods in the teaching of exercises, to change the students ’reliance on teachers’ explanations in the process of teaching, to emphasize the acceptance of learning, rote memorization, The status quo of mechanical training, a single interaction between teachers and students for the interaction between students and students, pay attention to individual differences in students, to create a teaching environment that can guide students to take the initiative to participate in, stimulate students’ enthusiasm for learning so that each student can be fully developed , Seek innovative teaching, it becomes a heavyweight
