the researcher found that to tt = 47.4 1.99 in significance level 5 and to tt = 47.4 2.65 in significance level 1. It meant there was obvious difference
between average score from the result of teaching descriptive text in experiment class and controlled class. It could be inferred that teaching descriptive text was
more effective by using mind mapping than GTM.
E. Theoretical Framework
According to the explanation that stated by many experts in language above; Descriptive text is one of genres in reading selection that is learned by
students either at junior high school or senior high school and the purpose of descriptive is to tell about the subject by describing its features without including
personal opinion. The aim of description is to enable the reader what something looks like. It attempts to paint a picture with words. In this sense, the description
also attempts to put the reader directly in touch with the physical world within the readers‟ senses.
And mind mapping technique is often created around a single word or text, placed in the center, to which associated ideas, words and concepts are added.
They generally take a hierarchical or tree branch format, with ideas branching into their subsections. Besides, mind mapping as a useful technique improves the way
you take notes, and supports and enhances your creative problem solving. It means that mind mapping can quickly identify and understand the structure of a
subject, and the way that pieces of information fit together, and it can encourage creative problem solving, and hold information in a format that your mind finds
easy to remember and quick to review.
F. Hypotheses
In this study, the writer uses alternative Hypothesis Ha and null Hypothesis Ho as below:
Ha = “There was an effect of using mind mapping technique toward comprehension of descriptive text of seventh grade
student of SMP Pelita YNH” Ho =
“There was not an effect of using mind mapping technique toward comprehension of descriptive text of seventh grade
student of SMP Pelita YNH”
Furthermore, the hypothesis of this research paper is there was not an effect of using mind mapping technique toward comprehension of descriptive text
because students still have low knowledge and skill to grasp the keywords of the texts. Moreover, it is a new technique implemented in the classroom both for the
teacher and for students. Therefore, it is probably difficult to carry out and adapt mind mapping technique within short time during the research.
