科学是在实验中产生的,同时又是通过实验进行论证的,因此要学好科学知识就必须重视实验。调查表明,多数学生对实验是非常有兴趣的,但是,由于受时间与空间条件的限制,学生在课堂教学中能接触的演示实验或探究实验还是比较少的。因此,为了解决这一矛盾,教师可以根据教学需要,让学生单独或编组,根据家庭的具体情况,独立或合作设计并完成的一些实验。家庭实验对于提高学生对于理化生课程的学习兴趣、动手能力以及学校的教学水平都是非常有意义的。 Science is produced in the experiment, but also demonstrated through experiments, so to learn scientific knowledge, we must attach importance to the experiment. The survey shows that most of the students are very interested in the experiment. However, because of the limitation of time and space, there are still few demonstration or inquiry experiments that students can contact in the classroom teaching. Therefore, in order to solve this contradiction, teachers can independently or cooperatively design and complete some experiments according to their teaching needs, individually or in groups, and according to the specific conditions of the family. Home experiments are very meaningful to improve students’ interest in learning, practical ability and teaching level in physics and chemistry.
