Some researchers such as Liu and Lee
Liu 2013 and Hwang et al.
Hwang 2011 have developed electronic learning platforms utilizing knowledge visualization tools such as concept maps. By illustrating the relationship between different concepts in a concept map and making use of the concept map, these projects not only enhance students' motivation, but also consolidate the learning outcomes. Unfortunately, as these projects focus on natural science education in pre-university level, they may not be suitable for university in which the subjects are more diverse and the concepts are more complex and abstract.
Our platform overcomes the aforementioned issues by (1) organizing the course content by knowledge graphs which indicate the dependencies of concepts, (2) refining the course content management system so that learners can retrieve the information they want efficiently, and (3) integrating the quiz questions with the course material.
