MENO-II: An AI-Based Programming Tutor.

Abstract : MENO-II is a computer-based tutor intended to help novices learning to program in Pascal. The BUG-FINDing component attempts to find non-syntactic bugs in a student's program. It draws on a database of 18 common bug types, represented as templates, and attempts to match these templates against its analysis of the student's program. The TUTORing component then attempts to infer the misconception that might underlie the bug and present the student with remedial instruction. We tested the BUG-FINDing component in a classroom setting: we report here on an analysis of the system's performance. (Author)
