Outline of Final Research Achievements

We analyzed student free-style comments written by themselves just after every lesson and extract words related to student learning characteristics, learning performance and/or class assessment. We set five learning attributes:
effort, attitude, understanding, collaboration, findings and proposed novel methods to estimate student learning performance using the learning attributes. The methods use several machine learning methods such as SVM, Artificial Neural Network, Random Forest, LDA, pLSA, LSA, Word2Vec, Multi-instance Learning. We found there were high correlations between combination of the attributes and student grades. We also showed the effect of teacher interventions for improving the quality of student comments, understanding student learning situations and estimating student learning performance.
