新课程标准中要求课堂教学要体现出生活性,并且要回归日常生活。初中科学教学不仅要营造生活化的教学情境,而且所布置的作业或练习也要具有生活性,从而培养学生学以致用的能力。 The new curriculum standard requires classroom teaching to reflect birth activity and return to daily life. The science teaching of junior middle school should not only create a life-oriented teaching situation, but also the homework or exercises that are arranged must also have a living nature, so as to cultivate students’ abilities to apply their knowledge in learning.
