探究实验是基于问题的学习活动,但在应用探究实验进行化学教学活动的过程中,我们发现存在一些问题:①学生固有的学习习惯阻碍了探究的顺利进行。②学生群体对探究实验的理解能力、探究能力、操作能力和实验设计能力存在差异,使一些探究实验需要较长的时间才能完成。③在教学中边讲边实验的探究方式,操作的局限性较大,除了实验室安排困难外,班级的教学秩序也不理想,受上课时间和教学进度的限制,探究常常局限于表面,难以深入,学生没
Inquiry experiments are problem-based learning activities. However, in the process of applying inquiry experiments to chemistry teaching activities, we found that there are some problems: 1 The inherent learning habits of students hinder the smooth progress of inquiry. 2 There are differences in students’ understanding ability, inquiry ability, operation ability and experimental design ability of inquiry experiments, which makes some inquiry experiments take a long time to complete. 3 In the course of teaching, the method of inquiry and experimentation has large limitations. In addition to the difficulties in laboratory arrangement, the teaching order in the class is not ideal. Due to the limitation of class time and teaching progress, the inquiry is often limited to the surface. In-depth, students did not
