Data Processing and Analysis of Pretes and PostTest Data was collected from pretest and post was obtained from student, which covered material about optics instrumen then being rocessed by calculating score of students’ pretest and posttest that formed in multiple choice. Each correct answer was given a score one, while a wrong answer was given a score zero. Then, to find out final score with scale 100 from multiple choice done by using formulation, as given: Where, SS = Score obtained by student SM = Maximum Score FS = Final Score After getting the final score, pretest and posttest being analyzed for the effectiveness of their instruction by finding the value of N-Gain. The value of N-gain were categorized as high, medium and low. As follows : a. Average Normalized Gain in obtaining the average normalized gain score in this research was done by ©Microsoft Office Excel 2007. Average normalized gain is a method to assess the effectiveness of instruction. The average normalized gain is commonly used to assess students’ performence in pre- and post-test. the average or normalized could be calculated by using average scores of the class or individual student’s score. Generally, both of calculation has Novi Yufitri, 2014 Identify Role Of Learning Style Towards Students’ Cognitive Achievement And Creativity On Optics Instrument Concept Universitas Pendidikan Indonesia | repository.upi.edu | perpustakaan.upi.edu different product. The properties of two result were explored for several ideallized situations. The results indicated that it might be able to utilize the the difference between the two results to extract information about how population may have changed as a result of instruction. Average normalized gain g describe as the ratio of the average improvement in participantscores from pre-test to the post-test rescpectly to the maximum possible improvement. G can be calculated, as follows : Hake 1998 noted that the normalized gain has a significant measurement of how well a course though topics of physics to students. Hake regarded normalized gain in the category of high, medium and low. As illustrated in table below : Table 3.12 Category of Average Normalized Gain Normalized Gain Category 0.3 Low 0.3 X 0.7 Medium 0.7 High Hake, 1998 3.

CHAPTER V CONCLUSIONS AND RECOMMENDATIONS

A. Conclusion

Research of Learning Style Towards Students’ Cognitive Achievement and Creativity on Optic Instrument Concept has been conducted systematically, based on the research result it is acquired some conclusions as follows: 1. Auditory learners are prevailed with 36.36 , followed by Visual learners 27.27 , were readwrite and kinesthetic learners are 18.18. not all learners understand about their preference laerning style it is proof by no aural learners that is choose a project assigment which are design acoording to their learning style. 2. The learning style is an factor that can not be neglected in teaching learning process, it is noted based on the result of this study that learning style has a important role towards cognitive achievement. It is proof the alternative hypothesized retain H 1 that noted the different cognitive achievement within group of learning style through in posttest after the implementation has been conducted, with significancy level 0,003 using ANNOVA analysis. The group who choose a appropiate project with their learning style show higher improvement rather than group who are not. Visual and kinesthetics learners almost reached highest score in each cognitive test item C1-C4, it happened because undirectly they have more advantages in learning process and project itself. 3. The learning style is take a important role and can not be neglected in the creativity process. It is proof by the student who choosed a project product baed on their preference learning style has higher creativity on product result rather than students who Novi Yufitri, 2014 Identify Role Of Learning Style Towards Students’ Cognitive Achievement And Creativity On Optics Instrument Concept Universitas Pendidikan Indonesia | repository.upi.edu | perpustakaan.upi.edu are not choose project which are appropiate with their learning style.

B. Reccomendation

Based on the findings of the research that has been conducted and concluded, there are several recommendations that necessary to be conveyed by the researchers, some of them are: 1. It is necessary to conduct the learning style questionaire inventory in the begining of clas to know better understanding about student preffernce learning style. 2. Learning style is an aspect that can not be neglected in the diversity of student during teaching and learning process. Teacher should know that every student is unique and also student themselve shoul know that they are difference. Through learning style, not only teacher to know how to teach the student but also for student themselve to know how they learn better. 3. To develeop creativity based onthe learning style, teacher take an important role as a guidance to arrange nad guide which is potential for them. So, the development of creativity can be maximize. 4. For the next researchers who has interest in learning style, it is better to have a control and experiment class. Thus, the role of learning style itself can be seen clearly and the result are not bias between the high achiever and low achiever.
