grades early in order to support learners of medium or low achievement in on-demand courses. Considering the individual learning style affects learners' performance, page transition and reading time of online textbooks are as the indicators of learning style in this paper. Feature vectors, which represent page transition and reading time, are constructed from data recorded in LMS when learners have accessed the online textbook. A prediction of mid- and low-achievers is treated as a classification problem using the feature vectors in machine learning. Using the Word2Vec, a variance representation vector in each page of online textbook was derived. Then, the sum of variance representation vector added along the each learner's page transition was one of the feature vector. The center of variance representation vector along the each learner's page transition was another feature vector. Using these feature vectors, we constructed a machine learning model and verified its accuracy by KFold Cross Validation.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告教育学習支援情報システム（CLE）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2023-03-03","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"2023-CLE-39"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"created":"2025-01-19T01:24:36.181420+00:00","updated":"2025-01-19T12:55:44.931438+00:00","id":225089}
