Treffer: Tendency Analysis of Python Programming Classes for Junior and Senior High School Students.

In this study, we analyze Python program codes and questionnaire results collected in the programming classes for 23 senior high school students on December 19, 2020, and for 48 junior high school students on August 11 and 12, 2021. Each student entered and executed the 168 Python programs described in the text on Google Colaboratory using each personal computer. Students' programs were collected by sharing in Google Drive. In the analysis, the similarity matrix is obtained from the correct / incorrect relationship of the students' programs and hierarchical clustering is performed by Ward's method and visualized by the dendrogram. As a result, the cluster is confirmed from the correct/incorrect relationship. For the questionnaire, we use conjoint analysis for the relationship with the number of correct answers, and Quantification Method of the Third Type for the relationship with the questionnaire category. As a result, we confirm that the tendency for the senior high school students is the same as or different from that for the junior high school students. [ABSTRACT FROM AUTHOR]
