Suggests a moving pictorial tool to help teach principles in the bubble sort algorithm. Develops such a tool applied to an unsorted list of numbers and describes a method to derive the run time of the algorithm. The method can be modified to run the times of various other algorithms. (JN)

Argues that a computer-based programming tutor for novice programmers needs to take into account not only the types and frequency of bugs found in the programs, but the intentions and knowledge state of the programmer. A first version of such a program was developed on the basis of the bug types found in a number of pencil-and-paper studies with…

Computer assisted instruction, software design, and course organization are among the topics discussed in this varied, 15-paper collection which includes descriptions of specific projects, general essays and practical suggestions for improving or implementing computer-oriented instruction.

A computer simulation model for allocating facilities and physical space is presented as a means of optimally allocating available educational resources. The model allows the decisionmaker to change specific program allocations, system parameters, and other controllable variables in order to determine the effects, both cost and utility, of these…
