CHAPTER II REVIEW OF RELATED LITERATURE
This chapter provides the review of related literature for this study. This chapter talks about review of previous study, writing, mind mapping, and tree diagram
explanation.
2.1 Review of Previous Study
In conducting this research, the writer does not find a lot of previous studies about mind mapping in writing. Here are previous studies that have relation with this
research. First is a research that was conducted in 2010 by Utami entitled The
Use of Prewriting Strategies: Brainstorming and Mind Mapping in Essay Writing Recount. In this research, it is proven by the result of the research that there is
difference between students who used prewriting strategies than the students who did not use prewriting strategies. The achievement reached by the students who
used brainstorming and prewriting is higher than the students who did not. By using brainstorming and mind mapping, the students can improve their writing
because they can get many ideas. The students also felt more exciting because they could use colors, images, and imagination.
The second research was conducted in 2008 by Susanto entitled The Application of Mind Mapping Method in Teaching Descriptive Writing. The
objective of this study was to know if there was an effect of applying mind

mapping method in teaching descriptive writing to the third grade students of senior high school. The result of this study was that there is a significant
difference between the experimental group and the control group. Most of the students were interested in exploring their imagination using mind mapping. From
this research, the students are trained to think widely and be creative. Susanto, in his research, proposed some weaknesses. When students use mind mapping, they
spend more paper sheets to do the test and more time. He also must have a broad knowledge especially in vocabularies because the students sometimes asked the
English translation of the difficult words related to the topic. There is also a previous study that concerned with mind mapping, but
it has nothing to do with writing. It is a final project written by Farida 2010 entitled Efektivitas Pembelajaran Sistem Gerak Pada Manusia Melalui
Pendekatan CTL Berbasis Mind Mapping. The result of this research was the students can learn about kinetic system for human being easier than the
conventional way. Unfortunately, the writer could not find any previous study about tree
diagram in teaching writing. Hence, she focuses on the investigation of the effectiveness of tree diagram as teaching writing. The research introduces the use
of tree diagram to the teachers, particularly the English teacher of the eleventh grade students of SMA Negeri 2 Bae Kudus.
