磨課師(MOOC)的出現增加了學生學習知識的可能性。伴隨著開放式課程素材，學生擁有非常大的彈性來安排、調整自身的學習方式。而開放式課程素材並非只影響學生的學習，同時也給予課程講師充分的空間來安排課程內容及素材的編排、使用。這樣的彈性造就了MOOC課程的多樣性，例如課程沒有練習題或課程沒有考試。而這樣的彈性會造成學生無法在學習過程中檢視自己的學習成果。為此，我們分析MOOC課程主要的學習方式，觀看課程影片，來預測學生的學習成效，並回饋給學生，讓學生作出自適化的調整。我們透過收集學生觀看影片時的動作資料以及動作發生的時間點，根據間隔效應進行分析，分為學習行為分析與學習活躍度分析兩個類別。然後，利用深度學習的方式，去預測該學生於該學習模式下的學習成效，課程分數與課程等第。最後，系統會將分析數據視覺化成三種圖表，每日學習時間長條圖、每周學習熱點圖、活躍度雷達圖，並將圖表與預測結果反饋給學生，讓學生得以得知目前的學習狀況並加以調整自己的學習方式。

The emergence of massive open online courses(MOOC) increases the possibility of students learning. With the open course materials, students have great flexibility to arrange and adjust their own learning methods. The open course materials not only affect the students' learning, but also give the course instructors sufficient space to arrange the course content and materials. This flexibility has created a diversity of MOOC courses, such as courses without exercises or without exams. It may prevent students from reviewing their learning effectiveness during the learning process. To this end, we analyze the main learning methods of MOOC, video watching, to predict students' learning performance, and give back to students, so that students can make adaptive adjustments. We used the learning logs of videos, analyze them according to the spacing effect, and divide them into two categories: learning behavior analysis and learning activity analysis. Then, use the method of deep learning to predict the student's learning performance, course score and course grade. Finally, the system will visualize the analysis data into three charts, daily learning time bar chart, weekly learning heat map, learning radar chart, and feed back the charts and prediction results to the students, so that the students can learn the current learning status and adjust their learning methods.
