各位看官,上回我们已向各位就教育技术的发展概况作了一次勾勒,这回接着讲现代远程教育中广泛使用的无线电广播手段。大家都可以想象一下:假如当今社会没有广播电视,我们的休闲时间会怎样度过?千家万家又是怎样可以收听收看同样的节目呢?这可是广播手段大显身手的结果。远程教育也同样离不开这种“千里传音、万里传像”的技术,只有这样,才能实现远距离大范围的教学。
Tell me what you saw, last time we outlined to you a general overview of the development of educational technology, and then we talked about the radio broadcasts that are widely used in modern distance education. We all can imagine: If today’s society does not have radio and television, our leisure time will be how to spend thousands of thousands of families is how to listen to watch the same program? This is the result of broadcasting means to show their talents. Distance education also can not do without this kind of “thousands of miles of sound transmission, Miles biography” technology, the only way to achieve long-range teaching.
