电教媒体在学科教学中的运用已经深受每一位老师的青睐。在科学教学中,我们可以运用电教媒体来激发学生学习兴趣,来突破教学重难点,来培养学生的探究能力,促进学生课后进一步的研究,从而构建高效的科学教学课堂。 Audio-visual media in the use of subject teaching has been deeply favored by every teacher. In science teaching, we can use audio-visual media to arouse students’ interest in learning so as to break through teaching difficulties and hardships, to cultivate students’ inquiry ability and promote students’ further study after class so as to construct an efficient science teaching classroom.
