First year pre-clinical medical students were taught about blood grouping and haemostasis using four audiotapes and associated booklets as the sole method of formal instruction. The audiotapes were readily accepted by the great majority of students as a replacement for lectures and those who listened to the tapes scored significantly higher in a multiple choice test 10 months later than did a previous years's student who had covered the same topics by means of lectures. If booklets are provided for each student, tapes are more expensive than lectures in terms of the time and running costs involved. By contrast, if booklets are sold or made available on loan with the audiotapes, then costs become equivalent when tapes are distributed to four to six average-sized medical schools and become increasingly cheaper as the number distributed increases. Other less readily quantifiable benefits of audiotape learning are discussed and it is concluded that in terms of both costs and effectiveness of learning, audiotapes can usefully replace a proportion of lectures in a conventional course. Consideration should be given to the provision of more space for audiotape tuition and less for formal lectures.
临床前医学专业一年级学生通过使用四盒录音带及相关手册作为唯一的正规教学方法来学习血型分类和止血知识。绝大多数学生欣然接受录音带作为讲座的替代方式，并且在10个月后的多项选择题测试中，听录音带的学生比前一年通过讲座学习相同内容的学生得分显著更高。如果为每个学生提供手册，那么从所涉及的时间和运营成本来看，录音带比讲座更昂贵。相比之下，如果手册与录音带一起出售或出借，那么当录音带分发给四到六所中等规模的医学院时，成本就会相当，并且随着分发数量的增加会越来越便宜。文中还讨论了录音带学习的其他一些较难量化的益处，并得出结论：就学习成本和效果而言，录音带可以有效地替代传统课程中的一部分讲座。应该考虑为录音带教学提供更多空间，减少正规讲座的空间。
