化学是一门以实验为主的科学,可见实验在化学教学中的重要性。初中化学实验是学生获取化学知识的主要手段之一,化学实验可以使学生获得更多的感性认识。素质教育要求教师在教学过程中充分发挥学生的主观能动性,让学生真正成为学习的主人。要想达到这一目的,加强学生的实践活动是最有效的途径。通过化学实验教学,对激发学生的学习兴趣,培养学生的合作探索精神,以及良好习惯的养成都是非常有益的。初中化学新教科书安排的实验大体有以下几种呈现形式:课堂实验、以探究为目的的实验活动、家庭小实验、实验习题。不同的实验形式在教学中对学生的要求是不同的,所起到的教学作用也是不同的。下面笔者谈一谈化学实验的重要性。
Chemistry is an experiment-based science, showing the importance of experiments in chemistry teaching. Junior high school chemistry experiment is one of the main means for students to acquire chemical knowledge, chemical experiments can make students get more perceptual knowledge. Quality education requires teachers to give full play to students’ subjective initiative in the teaching process so that students can truly become masters of learning. To achieve this goal, to strengthen students’ practical activities is the most effective way. Through chemistry experiment teaching, it is very beneficial to stimulate students’ interest in learning, cultivate the spirit of cooperation and exploration of students, and develop good habits. Junior high school chemistry textbooks arranged experiments generally have the following forms: classroom experiments to explore for the purpose of experimental activities, family experiments, experimental exercises. Different experimental forms have different demands on students in teaching, and their teaching effects are also different. Now I talk about the importance of chemical experiments.
