电教媒体是电学、光学、声学等物理科学技术单项或综合运用的音像媒体。它既是传输知识信息的主要载体,也是调控课堂教学的有效手段。巴班斯基提出“教学手段的优选是实施教学过程最优化的主要方案之一。”因此,在语文教学中,巧妙地使用电教媒体利于强化学生对课文内容的理解。笔者认为,使用电教媒体,必须做到“四个结合”。 Audio-visual media is electrical, optical, acoustic and other physical science and technology alone or comprehensive use of audio-visual media. It is not only the main carrier of transmitting knowledge and information, but also an effective means of regulating classroom teaching. Babanski proposed that “the optimization of teaching methods is one of the main programs to implement the optimization of teaching process.” Therefore, the clever use of audio-visual media in Chinese teaching helps to strengthen students’ understanding of the content of the text.
