——负责控制教材设计、制作和发行以及处理对学生进行远距离教学活动的教务行政系统,一般要比正规制度在同一情况下更为清楚地同教学职能分开,其本身状况也比较复杂。在任何学生入学前,教务行政系统的期初投资可能是大量的,整个说来,也比正规制度在同一情况下开销更多。洛姆伯尔在一些远距离制度中的工作经验使他能鉴别远距离制度的主要成本发生器,表明成本如何随关键性投入或产出变量的变化而变化。 - The academic administration system that controls the design, production and distribution of textbooks and handles distance learning activities for students is generally more clearly separated from the teaching function than the formal system under the same circumstances, and the situation itself is rather complicated. Before any student enters school, the beginning investment in the educational administration system can be substantial, and overall it costs more than the formal system in the same situation. Lombard’s work experience in a number of long-range systems enabled him to identify the major cost generators of long-range systems and show how costs can vary with changes in key inputs or output variables.
