Student log analysis functions for web-based programming education support tool pgtracer
Tetsuro Kakeshita, Kosuke Ohta · 2015
We are developing a programming education support tool pgtracer as a plug-in of well-known Web-based Learning Management System Moodle. Pgtracer provides fill-in-the-blank questions composed of a C++ program and a trace table to students. When a student answers a question by filling the blanks, pgtracer collects student's answers, elapsed time, evaluation result, etc. as student log. In this paper, we develop seven analysis functions to student log. The student log analysis functions are classified into the analysis functions of a student, those of a question, and those of an answering process. A teacher can analyze achievement level of the students and difficulty level of the problems utilizing the analysis functions. We also perform an evaluation experiment of the analysis function at an actual class and demonstrate the analysis result.
