在许多教育电视节目中，自说自话、漠视传播效果的现象比比皆是，许多本身不适合大众传播媒介单向播出的教育节目充斥荧屏，浪费了频道资源，让人痛心。以辽宁教育电视台为例，以前曾经把课堂教学性节目放在“黄金时间”播出，使观众对辽宁教育电视台的印象是“讲课的那个台”? In many educational television programs, the phenomenon of disregarding the effects of communication abounds, and many educational programs that are not suitable for one-way broadcasting by the mass media are full of screens, which istes the channel resources. To Liaoning Education Television Station, for example, the classroom teaching programs have been put on “prime time” broadcast, so that the audience of Liaoning Education Television Station is the “lectures that Taiwan”?
