Compile Error Collection Viewer: Visualization of Compile Error Correction History for Self-assessment in Programming Education

摘要

We have developed CocoViewer (Compile error Collection Viewer) for learners in programming to enable them to conduct self-assessment for compiling error records. CocoViewer generates charts that show a trajectory of reducing the correction time of the compile error that is calculated by logs recorded in students' computers during a programming course. Students can see lists of charts for many kinds of compile errors, as well as a particular detailed circumstance of error that is selected by a student. We hypothesized that the system promotes clear understanding regarding their compile error learning, which leads to encourage more experiences of compilation error correction, as well as to reduce unarticulated anxiety for the compile error. The system was tried in a self-assessment context at an undergraduate introductory programming course for approximately 100 non-CS students. The results in the questionnaire showed that the students appreciated the system for a reflection of their process, and we succeeded in reducing unarticulated anxiety for students. The results indicate that self-assessment with CocoViewer enable to boost students' motivation in programming education, which forms the basis of computer engineering education.
