美国心理学家布鲁纳认为:在学校教育中,所有教学计划在很大程度上将依赖于为达到教学目标而采用的教学媒体。在小学语文教学中,采用电教媒体进行教学,是提高教学质量的重要措施之一。而且电化教学采用幻灯、投影、录音、录像、电影、电视、计算机等教学,对提高教学质量具有十分重要的作用。 Bruner, a psychologist in the United States, believes that in school education, all instructional programs will largely depend on the medium of instruction used to achieve their teaching goals. In primary Chinese teaching, the use of audio-visual media for teaching is one of the important measures to improve the quality of teaching. And the use of electronic teaching slide, projection, recording, video, movies, television, computer and other teaching, to improve the quality of teaching has a very important role.
