在本文中，我們透過比對學生於電子書中畫的重點和教師畫的重點的一致性來判斷學生的閱讀理解能力，比較TextRank, RAKE, BERT三種方法的代理度量(Proxy measure)效能，透過語言生成模型GPT-2產生小考問答題，透過語言代表模型BERT自動批改學生答案，最後根據批改結果自動給予學生建議並將結果反饋給教師，以完成高度自動化的閱讀理解能力智慧化評量。
;In recent years, various educational resources have been gradually digitized, e-learning platforms have gradually become popular, and students’ learning activities have been digitized. At traditional teaching sites, teachers need to understand students’ reading comprehension, often interacting through quizzes or in-class activities. In today′s e-learning platforms, how to measure students′ reading comprehension is an important topic in the field of learning analytics.
With the rapid development of artificial intelligence, the field of natural language processing has made significant breakthroughs in recent years. This paper hopes to use state-of-the-art natural language processing technology to find the best way to measure students′ reading comprehension. In addition, teachers want to know students′ reading comprehension ability is usually achieved by marking students′ quizzes. However, teachers often spend a lot of time and labor on setting and marking exam papers. This paper uses natural language processing technology to automate these two steps to help teachers understand students′ reading comprehension more quickly.
In this paper, we measure the reading comprehension of students by comparing the consistency of the markers drawn by students in e-books and the markers drawn by teachers, then we compared the proxy measure performance of the three methods of TextRank, RAKE, and BERT. In quiz generation phase, we use GPT-2, a state-of-the-art language generation model, to generate quizzes by parsing materials. In the grading phase, we use BERT, a pre-trained language understanding model, to grade students’ answers automatically, and give them guiding according to grading results to complete a highly automated reading comprehension measurement framework.
