COST-EFFECTIVENESS ANALYSIS ON DISTANCE EDUCATION

该研究分析了使用PictureTel系统（一种通过电话线的压缩图形系统）进行远程教育的结果，并与传统的课堂教育进行了比较。大阪的老师给东京的学生做了一次讲座。为了比较远程教学和课堂教学，同一位老师在东京讲课。尽管从遥远的地方传来的教导会使人们对教学的评价比用传统的方式授课要低一些，但是通过特别注意讲课的方式，可以把负面影响降到最低。远程教学的成本不到传统教学的一半。通过电话线进行小规模的远程教育是可行的。为了评估长期影响，对UAJ毕业生的货币影响是根据他们通过问卷调查收集的年收入来计算的。通过回报率将它们与直接成本和间接成本进行比较。结果表明，除了本科学历外，UAJ教育对毕业生的回报率很高。如果UAJ在全国范围内扩张，学生数量会增加，那么成本效益会更好，并且由于远程教育的规模经济，政府负担的比例会降低。该研究还旨在确定对UAJ效果有强烈影响的因素。研究发现，对初级效应影响最大的因素是高质量的教育。另一方面，影响持续效应的因素是职业优点方面的“动机”和文化水平提升方面的“动机”和“知识获取”。因此，吸引积极的申请人，并在他们开始在UAJ学习时激励他们，对于实现大学的目标至关重要。

The study analyzes the results of distance education using the PictureTel system, a compressed-graphics system via telephone lines, in comparison with traditional in-class education. The instructor in Osaka gave a lecture to the students in Tokyo. To compare distance instruction with in-class instruction, the same instructor lectured in Tokyo. Although instruction sent from a distant place makes the evaluation of instruction somewhat lower than what it would have been if the same had been given in a conventional manner, the negative impact can be minimized by paying special attention to the way of giving a lecture. The cost of the distance instruction was less than half of that of instruction in a conventional style. tance education for a small group sent via telephone lines is feasibe.For evaluating long term effects, the monetary effects on UAJ graduates were calculated on the basis of their annual earnings collected through a questionnaire survey. They were compared with direct and indirect costs by using rates of return. The result shows that UAJ education yields high rate of return to the graduates, excepting the person who had bachelor degree before entering UAJ.If the student number increases by UAJ's nationwide expansion, the cost effectiveness will be better and the ratio of government burden will decrease because of economies of scale in distance education.The study also aims at identifying the factors that have strong influence on the effects of UAJ.It has been found that the factor which has the most influence on the primary effects is education of high quality. On the other hand, the factors influential to the continuative effects are "motivations" in terms of vocational merits and "motivations" and "the acquisition of knowledge" in terms of the enhancement of one's cultural level. It follows that attacting motivated applicants and motivating them at the time they start studying at the UAJ are crucial in achieving the objectives of the university.
