Researchers indicate that motivation is critical in students′ reading behavior and habit. Therefore, maintaining students′ reading motivation and habits deserves our attention. In addition to vocabulary recognition, the breadth and depth degree of books students choose to read is also critical factor affecting reading ability. However, teachers seldom instruct students on how to select the books. It is also difficult for teachers to track students′ reading status to set their reading direction. With the development of internet technology, E-portfolio is a helpful tool for the teacher to monitor students reading behavior. This study develops the visual reading portfolio system based on a knowledge graph to provide teachers and students with a dashboard indicating the reading status of individuals and peers. In addition, this study integrates the system into an elementary school for 35 fourth and fifth-grade students. The reading and behavior data in 6 weeks are collected and analyzed to explore students′ reading comprehension, motivation, self-regulation, and reading behavior. The results indicate that the reading graph is an essential medium in guiding students to choose unfamiliar book topics or deeper-level books. Moreover, compared to students with higher reading comprehension, the knowledge graph is more helpful in enhancing students with lower reading comprehension, and significantly improves reading preference.
