实验是化学教学中的重要组成部分,也是学生获取知识、发展能力的重要途径。然而,由于我们教师对实验教学重要性的认识仅停留在能提高学生的学习兴趣、作为辅助化学概念原理的教学手段、应付实验考试等上面,导致化学实验的教学效果大打折扣,不仅影响了学生科学素养的养成,也严重影响了化学课程目标的达成。为了确保实验在化学课程中发挥应有的教学功能,除了开足化学课程中要求的实验课外,如何提高化学实验教学的有效性是我们 Experiments are an important part of chemistry teaching. They are also an important way for students to acquire knowledge and develop their abilities. However, because our teachers’ understanding of the importance of experimental teaching only stays at the level of improving students’ interest in learning, as a means of assisting the principles of chemical concepts, and coping with experimental examinations, etc., the effectiveness of teaching in chemistry experiments is greatly reduced, not only affecting students. The cultivation of scientific literacy has also seriously affected the achievement of the objectives of the chemistry curriculum. In order to ensure that the experiment plays a proper teaching function in the chemistry curriculum, in addition to opening the required experimental course in the chemistry course, how to improve the effectiveness of the chemistry experiment teaching is
