十二年國民基本教育以「核心素養」為主軸,旨在培養國民適應現在的生活以及面對未來挑戰所需具備的知識、能力與態度,為了提供多元化的課程內容並確保學生具備相應的基本學力,教學重心從教科書轉而專注於學生需求,使教師承擔課程設計的挑戰,考驗教師資訊蒐集與知識轉化能力的同時卻也增加教師備課時的負荷。
為了拓展課程領域邊界,提供與課程主題相關的書籍資源,本論文建置課程相關書籍推薦模型,從TAAZE讀冊網站爬取147,990本書籍資訊,利用文字探勘技術分析11個課程教案,提供課程關鍵字的關聯分析,以隱含狄利克雷分佈模型成功找尋隱含於課程中的主題,再以餘弦原理計算課程與書籍間的距離,並給予課程相關的書籍推薦,能夠提供與課程相關並且教師感興趣的書籍。問卷結果顯示書籍推薦系統能夠提高課程品質及教師的工作效率,減少教師在尋找課程資訊的時間與壓力,有助於教師在備課時取得課程相關的學習資源,使教師持續朝核心素養的教學精神邁進,本論文可作為未來發展學習資源推薦系統之參考。
Developing students' Core Competencies is the critical purpose of K-12 Education in Taiwan. The goal of K-12 Education is to create students’ knowledge, ability, and attitude to face future challenges. The focus of teaching turns to ensure that students have essential competencies. This makes teachers encounter more tasks on curriculum design, information collecting and the ability to transform the knowledge while increasing the loading on teachers.
To expand the boundaries of the curriculum, and to provide reference books related to the subject of the curriculum. This paper constructs a course-related book recommendation system based on Latent Dirichlet Allocation topic models. Collect 147,990 book information from the TAAZE website, and use text mining technology to analyze 11 course teaching plans. Then use the cosine principle to calculate the distance between the course and the book, and recommend books related to the course. The questionnaire results show that book recommendation system can improve the quality of the courses, work efficiency of teachers and reduce the time and pressure of teachers to search for course information when preparing the lessons. The results can be a reference when developing a learning resource recommendation system in the future.
