广播电视大学是采用现代化教学手段进行远距离教育的一种新型学校,它克服了传统教育的空间封闭性和时间局限性,拥有普通高校无法比拟的时空优势。但是从它的远距离特性看,作为教学主体的学生与教学主导的主讲教师彼此分离,相距遥远,形成电大教学方式的特殊性。主讲教师不能及时得到学生的反馈信息,学生得不到主讲教师的亲自指导,双方不能沟通,不能交流。而这种沟通和交流有赖于辅导教师,在主讲教师进行远距离授课之后,在学生已经通过广播电视课时教材有所理解的基础之上进行的面授教学就形成了电大独具特色的授课形式——辅导课(有人称之为二级讲授)。辅导课是电大教学系统中的有机组成部分,是广播电视课的延伸和补充,因此探讨这种授课形式很有必要。笔者根据多年上《普通化学》、《无机

However, from its long-distance characteristics, the students as the teaching subjects and the teachers who lead the teaching are separated from each other and are far apart, forming the particularity of TVU’s teaching methods.

Tutorial is an integral part of TVU teaching system is an extension of radio and television courses and supplementary, so explore this form of teaching is necessary.
