新课导入技巧很多,对于不同的新课内容选择怎样的导入技巧才能更好的揭示课题,导入新课是课堂教学不可缺少的重要一环。在这里新课的导入能否激发起学生的学习兴趣,是课堂导入教学的关键。针对当前中学生有厌学情绪,学习自觉性比较差等特点,我认为更应该重视化学课堂导入教学激发学生的兴趣和热情,从而优化教学,提高化学课堂的教学质量。下面结合我的教学实践和研究,谈谈化学课堂教学中常用的新课的导入技巧。一、“实验”导入法化学是一门以实验为基础的自然学科,实验导入法当为新课导入的最佳方案。如在化学起始课中教师先做几个有趣的化学实验:如小小照明弹、清水变牛奶、肥皂泡炸弹等等,让学生观察思考,
There are many new teaching skills in the new class. It is better to reveal the topics for different new course contents and how to introduce the new skills. The introduction of new courses is an indispensable part of classroom teaching. Whether or not the introduction of a new lesson can inspire students’ interest in learning is the key to teaching in the classroom. In view of the current middle school students’ feelings of tiredness and poor learning consciousness, I believe that more attention should be paid to the introduction of chemistry class teaching to inspire students’ interest and enthusiasm so as to optimize teaching and improve the teaching quality of chemistry class. The following combination of my teaching practice and research, talk about the introduction of new classes in chemistry classroom teaching skills. I. “Experimental” Introduction Chemistry is a natural science based on experiments. Experiment introduction method is the best solution for the introduction of new courses. For example, in the Chemistry Initiation class, teachers first do several interesting chemical experiments: such as a small illumination flare, clear water to change milk, soap bubble bombs, etc., to allow students to observe and think.
