Secondly, there are many studies on the effectiveness of mind map in subject teaching. Frrand’s (2002) experiments proved that mind map can motivate learners to recall the written information. Tze Kiong et al (2012) claimed that mind map was in favor of students’ learning performance and helpful to take notes and review a lesson. Thirdly, mind map can be used as a teaching aid. Conole &Weller (2008:1-13) pointed that mind map was seen as an aid to instructional design, which not only can help designers achieve their expected goals but also motivate designers to discuss and share ideas with others during the design process. In addition, with the development of the technology, mind map has become a good E-Learning tool to increase learning interest and help learners organize and navigate the knowledge.
