化学教学离不开实验,在所有化学教学活动中,最吸引学生,最易让学生参与的就是实验.实验教学的功能不仅仅在验证和扩展化学知识,培养实验能力,更重要的是通过学生亲身的观察,操作和体验,去感知科学的理念,为学生走进科学提供了独特的形式.由于学生的不良实验习惯,加上课时的不足,许多老师都是在班上放视频代替学生的实验,造成了部分学生高分低能.学生做实验的不良习惯有:1.一到实验室,就乱动桌上的药品.
Chemistry teaching is inseparable from the experiment, in all chemistry teaching activities, the most attractive to students, the most easy for students to participate in is the experiment.Experimental teaching function not only in the verification and expansion of chemical knowledge, develop experimental ability, more importantly, through the students In-person observation, operation and experience, to perceive the concept of science, for students to enter the unique form of science due to bad habits of students, plus class hours, many teachers are in the class instead of video Experiments, resulting in some students score low energy.Experienced students to do bad habits are: 1.Once the lab, the table on the random drugs.
