学生是学习的主体。古语云:授之以鱼,不如授之以渔。教是为了不教,教会科学知识不如培养科学素质。化学学科由于它有一定的难记性,为聪明学生所不以为然;又由于它的综合性。为中下学生所畏难。所以在实验中培养好学生主动学习化学的兴趣、习惯、方法、能力和化学素质,显得尤为重要。 Students are the main body of study. Old saying goes: granted to the fish, it is better to grant the fishing. To teach is to not teach, the church scientific knowledge as training scientific quality. Because of its chemical discipline has some difficult to remember, for the discontented students; but also because of its comprehensiveness. Fear of middle school students. Therefore, it is particularly important to cultivate students' interest, habits, methods, abilities and chemical quality in experiments.
