演示实验是化学实验的重要组成部分,通常由教师在课堂上演示完成。演示实验可以较好地培养学生的观察能力、思维能力和创新能力,较好地揭示事物的本质,较好地发挥实验的育人功能,所以做好演示实验至关重要。现就演示实验教学的一些做法与大家分享。一、先睹为快,引人入胜演示实验对学生有很强的吸引力,学生一看到演示实验就兴奋。但从平时听课掌握的情况看,教师在进行
Demonstration experiments are an important part of chemistry experiments and are usually performed by teachers in the classroom. Demonstration experiment can better cultivate students’ observation ability, thinking ability and innovation ability, reveal the essence of things well, and give full play to the experimental education function, so it is very important to carry out demonstration experiments. Now demonstrate some experimental teaching methods to share with you. First, sneak preview, fascinating demo The experiment has a strong appeal to students, students excited to see the demonstration experiment. However, from the usual class to grasp the situation, teachers are in progress
