目前中等卫生学校化学课的教与学存在着难以调和的问题,教师的“难教”和学生的“难学”这对矛盾成为中等卫生学校教学面临的重大课题。应从传统的化学教学中解脱出来,在课堂上把化学知识和有趣的化学“小魔术”结合起来,提高学生上课的兴趣和集中他们的注意力,从而激发他们学习化学的主动性。 At present, the teaching and learning of chemistry classes in secondary health schools are difficult to be reconciled. The contradiction between the teachers ’“difficult teaching” and the students’ “difficult learning” has become a major issue facing the teaching of secondary health schools. Should be freed from the traditional chemistry teaching, the combination of chemical knowledge and interesting chemistry “magic trick ” in the classroom, to enhance students’ interest in class and to focus their attention, so as to stimulate them to learn chemistry initiative.
