化学是一门以实验为基础的自然科学,要提高化学课的教学质量,加强化学实验教学,特别是改革实验课的教学方法是一条重要途径。一、构思与目的在实验课教学中,加强“实验目的”的教学,“学生实验”让学生自己设计方案,适当增加“演示实验”数量,从而调动学生学习积极性,发挥创造性,激发学习兴趣,全面培养能力,克服传统教法(即让学生完全按照书本上规定的步骤做实验)限制学生思维,压抑积极性与创造性之弊端,达到提高化学课教学质量之目的。二、方法与步骤 1.重视“实验目的”的教学每次实验课都有明确的目的,实验课自始至终都应围绕着如何达到“实验目的”而进行。但大多数学生预习实验时只简单地照抄书本上的“实验
Chemistry is a natural science based on experiments. It is an important way to improve the teaching quality of chemistry classes and strengthen the teaching of chemistry experiments, especially the teaching methods of reforming experimental courses. I. Concept and purpose In the experimental teaching, strengthen the teaching of ”experimental purposes“, ”student experiments“ let students design their own programs, and appropriately increase the number of ”demonstration experiments“ so as to mobilize students’ enthusiasm for learning. Creativity stimulates interest in learning, comprehensively develops ability, and overcomes traditional teaching methods (that is, allowing students to follow the steps specified in the book to do experiments) to limit students’ thinking, suppress disadvantages of enthusiasm and creativity, and achieve the purpose of improving the teaching quality of chemistry classes. Second, methods and steps 1. Emphasis on the ”experimental purpose“ of teaching each experimental class has a clear purpose, experimental course from beginning to end should be based on how to achieve the ”experimental purpose". However, most students simply copy the “experiment” in the book when preparing the experiment.
