欲使学生能持久地、愉快地学化学;爱化学,就必须重视培养学生学习化学的兴趣。通过实践,我认为培养初三学生学习化学的兴趣,可从下列三方面作努力:一、加强实验包括增加演示实验的内容和学生实验的开设,布置切实可行的家庭实验。如要求学生回家制作明矾大晶体;从干电池中回收二氧化锰、碳棒和锌皮;观察石碱的风化、食盐的潮解;收集池塘中的沼气并点燃;自制植物指示剂;测定食醋、石灰水的酸碱性等。学生通过观察、操作和
For students to be able to learn chemistry persistently and happily, and to love chemistry, attention must be paid to cultivating students' interest in learning chemistry. Through practice, I think it is possible to cultivate the students 'interest in chemistry in the first three days of school from the following three aspects: First, to strengthen the experiment includes increasing the content of demonstration experiments and opening of students' experiments and laying out practical family experiments. Such as requiring students to go home to make large alum crystals; recovering manganese dioxide, carbon rods and zinc skins from dry cells; observing the weathering of the alkalis and the deliquescence of salt; collecting biogas from ponds and lighting; , Lime water acidity and so on. Students observe and operate
