如果学生对学习化学缺乏兴趣,甚至一见化学就头痛,一见化学老师就厌恶,则谈不上发挥学习的主动性和积极性和创造性了,学习效果可想而知。因此,在首堂课教学中,激发和培养学生的学习兴趣是提高学生学习质量的前提。 If students lack interest in learning chemistry and even see chemistry as a headache, seeing a chemistry teacher dislike them will not be able to exert their initiative, enthusiasm and creativity in learning, and the learning effect can be imagined. Therefore, in the first class teaching, to stimulate and develop student interest in learning is to improve the quality of students learning the premise.
