一、关于化学教学活动化学教学过程是通过一系列教学活动完成的。教学活动是教学过程中的师生双边活动。当学习内容、学习情景不同时,各阶段的具体活动内容也自然有所不同。在课堂教学中,我们倡导“活动建构”的教学模式,教师的教是为学生的学创设必要的外部条件,帮助学生有效的学习;而学生的学是基于对教师设计问题的思考和探究,在思考和探究中理解并掌握知识。化学教学活动建构的基本思路如下图:这个教学活动的一般过程具有一定的普遍意义。在一节课中,应该整体设计结构化的教学活动,按照最优化的原理合理安排学生的学
First, on the chemistry teaching activities Chemistry teaching process is completed through a series of teaching activities. Teaching activities are the bilateral activities of teachers and students in the teaching process. When learning content, learning scenarios are different, the specific activities of the various stages of natural content is also different. In classroom teaching, we advocate the teaching mode of “activity construction”. Teachers ’teaching is to create the necessary external conditions for students’ learning to help students to learn effectively. The students ’learning is based on the thinking of teachers’ design and Explore, understand and master knowledge in thought and inquiry. The basic idea of chemistry teaching activity construction is as follows: The general process of this teaching activity has a certain universal meaning. In a class, we should design structured teaching activities as a whole and arrange the students’ learning reasonably according to the principle of optimization
