要想上好科学实验课,就必须精心准备实验材料。只有在得力的助手、固定的材料员、学生的适当配合、材料的提前亮相以及材料的分批分发和材料的雪藏等方面做全面的有结构的材料准备,学生才能很好地进行观察实验,从而使学生的探究能力得到提高。 To take a good science experiment class, we must carefully prepare the experimental materials. Students should be able to conduct good observational experiments only if they are prepared in a comprehensive structured manner with the aid of a competent assistant, a fixed materialist, proper cooperation of students, early appearance of materials, batch distribution of materials, and snow storage of materials. So that students’ inquiry ability is improved.
