Study of Lecture Improvement for Teaching with Information Technology using Learner Characteristcs.

为了观察学习者的学习行为，对日本某大学的混合课程的本科生和硕士生进行了连续三年的调查。在这项研究中，学习者的特点和学习行为之间的因果关系的定量差异，学生水平（学士与硕士）和调查年份进行了测定。此外，为了确定学生在在线学习活动中的学习表现，引入了作文测试，并将其作为学士学位水平的混合和完全在线课程以及硕士学位水平的混合课程的评估工具进行了研究。此外，为了研究使用自动评估系统进行作文测试的结果，介绍了一个原型系统，并对结果进行了讨论。根据这些结果，混合学习可能的改进进行了讨论。

Bachelors and masters students who were enrolled in blended courses at a Japanese university were surveyed for three consecutive years in order to observe learners' behavior. In this study, the quantitative differences in the causal relationship between learner characteristics and learning behavior across student levels (bachelor vs. masters) and the survey years were determined. Additionally, to determine the students' learning performance in online learning activities, essay-testing were introduced and examined as assessment tools for blended and fully online courses in the bachelor level and for blended courses in the master's level. Also, to study the results of using an automated assessment system for essay-tests, a proto type system was introduced and results were discussed. According to these results, possible improvement for the blended learning were discussed.
