Discourse Analysis of Teachers' Commentary on Students

Abstract

In this paper, we describe the application of sentiment analysis and topic model on abundant teachers’ comments. The goal of the analysis is to explore the teachers’ sentiment and concerns when making comments. Preliminary findings indicate that students’ class performance, completion of homework and subject literacy are still the main evaluation indicators which cannot keep pace with assessment of 21st century skill. Meanwhile, we proposed teachers to make more pluralistic comments for encouraging students’ development.
