不久以前,录音机和电视在美国交了特殊的好运。它们除了担负录取声音、放映电视的正常任务以外,还荣幸地成了提高教员“生产率”的工具。据美国“新闻周刊”报道,路易斯安那州的一个天主教学校,为了解决教室拥挤和对“天孝”学生进行个别教育的问题,采用了双方互通的电括机、录音带和其他电子设备。据说,这样一来,一个教师可以同时教四班学生,而且可以打开桌上的电钮对学生进行单独谈话。使用这样多的科学设备来教学,教室拥挤的情况是不是会有所改进呢?“天才”的培养是不是更有成绩呢?天知道。也许正是由于录音机的效果不太令人满意吧,旧金山的教育家们想出了另一种办法:电视教学。在实验电视教学的时候,把学生分成三班。一个班在通常的教室里上课, Not long ago, tape recorders and television made special goodies in the United States.

It is said that, as a result, a teacher can teach four classes at the same time, and can open the button on the table to talk to students individually.
