化学实验方案的设计是在实施化学实验之前,根据化学实验的目的和要求,运用相关的化学知识和技能,对实验的仪器、装置和方法进行的一种规划。让学生自主设计实验方案,对于培养创造性人才具有深远的意义和不可估量的作用。一、学生自主设计实验方案法的课堂模式1.积极探索,发现实验问题思维是从问题开始的,发现问题是解决问题的起点,也是解决问题的一种动力。学生在学习中需要有启发性问题的引导,才能逐步深入。在
The design of a chemical experiment program is a planning of the instruments, devices, and methods of experiments, based on the purpose and requirements of chemical experiments and the application of relevant chemical knowledge and skills prior to the implementation of chemical experiments. Allowing students to design experimental programs independently has a far-reaching and invaluable role in cultivating creative talents. First, the students self-designed experimental program classroom model 1. Active exploration and found that the thinking of experimental questions from the beginning of the problem, found that the problem is the starting point to solve the problem, but also a driving force to solve the problem. Students in learning need inspirational questions to guide, in order to gradually. in
