Reviewing Learning Tasks through Detecting Specificity in Learning Log Data and Semantic Analysis Based on Information Structure —A Case Study on the Practical Use of Arithmetic Unit Word Problem Posing System: MONSAKUN—

Abstract

MONSAKUN is a software of learning by problem-posing for arithmetic unit word problems. We propose a learning log analysis and visualization method to support reflection activities on the practical use of MONSAKUN. First, we construct a method to convert learning logs into a multidimensional vector and use a clustering algorithm and a visualization method. Then, we apply the proposed method to a large set of log data obtained through practical use in all grades of the same public elementary school. As the analysis results with the proposed method, we concluded the proposed method useful because the proposed method could find some learning tasks that would be inappropriate for the students.
