Previous work assessing the effectiveness of computers in education has gone no further than acknowledging a network of interconnected variables (comprising a system) which contribute to computer impact and describing its component parts. An impact systems model developed by Glasman and Bibiaminov (1981) has been adapted to facilitate measurement…

The methodology of data envelopment analysis, (DEA) a linear programming-based method, is described. Other procedures often used for measuring relative productive efficiency are discussed in relation to DEA, including ratio analysis and multiple regression analysis. The DEA technique is graphically illustrated for only two inputs and one output.…

Discusses and compares advantages and disadvantages of large and small computer-based instructional systems. Predicted and actual costs in two systems--PLATO, which uses a mainframe system, and VITAL, a microcomputer-based system--are analyzed, and cost comparisons are made based on class size. (LRW)

Describes current status of library school technological support systems and determines effectiveness of various laboratory configurations by assessing relationship of selected input variables to following output measures: number of courses requiring laboratory use, number of database systems available, a service index, and an equipment…

Based on a doctoral dissertation that involved a study of the nation's 100 most successful school computer systems, this report summarizes the study's purpose, scope, methodology, resultant model, general observations, and future implications. The model is divided into two major sections: (1) strategic planning activities, focusing on computer…
