在化学课堂教学中,辅助课堂教学手段,能更清楚地说明问题,能更好地帮助学生接受和理解所学知识,手段方法要生动、逼真、贴切、多样。实验是化学教学的基础,是一种不能被代替的教学手段;多媒体效果显著,形象生动;计算机软件模拟化学反应原理,可帮助学生了解化学反应的实质,提高课堂教学的信息量;投影机既可投影片,还可投影实验,能促进学生对教学内容的进一步掌握。合理、科学地选择辅助教学手段,对学生化学概念的学习、化学原理的理解,提高分析、解决问题的能力都有帮助。 In chemistry classroom teaching, auxiliary classroom teaching methods can explain problems more clearly, help students better understand and accept the knowledge they learn, and the methods and methods should be vivid, realistic, appropriate and diverse. Experiments are the basis of chemistry teaching, which is a kind of teaching method that can not be replaced. The multimedia effect is remarkable and the image is vivid. The computer software simulates the chemical reaction principle to help students understand the essence of chemistry reaction and improve the amount of information in classroom teaching. Projection film, but also projection experiments, to promote students to further grasp of teaching content. Reasonable and scientific selection of aids to teaching methods can help students learn the concepts of chemistry, understand chemical principles, and improve their ability to analyze and solve problems.
