TEACHING COMPUTER PROGRAMMING WITH PROGRAM ANIMATION

The Teaching Machine is a software system for animation of computer programs. It allows the instructor in the classroom or the student on their own to single step through computer programs written in C++ or Java while observing the effect of each step on the state of a virtual machine. The state of the machine is represented in a number of ways including a presentation of the current state of evaluation of an expression, the state of memory in terms of bits or symbolic values, a box and arrow view of pointer based data structures. We report on recent developments in the Teaching Machine and on experience in the classroom.
