Many educational institutions implement blended lectures using an LMS. In addition, an analysis of learning activities using LMS learning records has been attempted by many educational institutions. In this paper, we analyzed students' learning activities and learning effects by using basic log data from an LMS on blended information literacy lectures to evaluate the lectures. In addition, we divided students into groups and analyzed their differences by the number of learning effects and learning activities. Additionally, in order to confirm which teaching materials were useful, this paper compared each group's usage of teaching materials and conducted a questionnaire with the students about lecture contents and teaching materials. As a result, we saw that there were variations in the use of teaching materials even among students with many learning activities. We report the details of these differences and make suggestions for improving lectures.
