一、自留作业更关注学生的个体差异性教育的起点在于,明确学生的个体差异并按差异施教。关注学生的个体差异,才能真正体现《化学课程标准》(实验)中提出的“不同的人在化学上得到不同的发展”这一基本理念。由学生本人根据自己的学习情况、兴趣爱好、能力强弱以及对教材重点、难点的把握,选择适合自己的作业。二、自留作业更能使学生产生学习化学的兴趣。 First, leaving homework more concerned about the individual differences in student education The starting point is to identify the individual differences in students and teach according to differences. Concerning the individual differences of students, can we truly embody the basic idea of ​​“different people get different development in chemistry” proposed in “Chemistry Curriculum Standard” (experiment). By the students themselves according to their learning, hobbies, ability and strength of teaching materials, difficult to grasp, choose their own homework. Second, leaving homework can make students more interested in learning chemistry.
