Possibility of Visualizing Descriptions of Reflection by Text Mining

Abstract

　It is necessary for the learner to continue learning while looking back, and both the learner and the teacher need to see the learning situation and the learner's transformation from the description of reflection in the learning process.　It is expected that learning will be possible.　However, as learning progresses, the amount of retrospective explanation increases.　It is not easy to grasp the learning situation and changes from the explanation.　Attempts have been made to visualize learners' retrospective descriptions by text mining, but there is little debate about what visualization methods are effective. 　In this paper, we examined what kind of visualization method is effective for understanding the learning situation and transformation from the description of the learner's reflection.　As a result, by using the co-occurrence network, it is possible to know in detail what the students have learned, the connection of the words explained by the students in retrospect, and the learning situation and transformation in detail.　I will It became clear that it was most effective to present the retrospective explanation as it was.
