Memory Diagrams:

Understanding the execution of an object-oriented program can be a challenge for a student starting a CS1 course. We have developed a type of diagram that we call a memory diagram that can aid the student's in understanding object-oriented programming and can assist the instructor in assessing the student's understanding. The advantage of memory diagrams is that they provide a visual way for someone to describe the object-related effects of each step of the execution of a program fragment. Memory diagrams are somewhat analogous to sentence diagrams used in the learning of English syntax.
