Pengaruh Pendekatan Multi Representasi dalam Pembelajaran Fisika Terhadap Kemampuan Kognitif Siswa SMA

Abstract

The aim of this research is to know the effect of multiple representations approach in teaching physics towards cognitive ability of senior high school students. Multiple representations have five advantages such 1) Accomodate the difference of intelligence capabilities, 2) Visualization of brain, 3) Help to construct other forms of representation, 4) Some of representations are useful for qualitative reasoning, and 5) Abstract mathematical representation is used to qualitative reasoning. The multiple representations which are used in this research are verbal representation, visual representation and mathematical representation. The research was carried out using a quasi-experimental methode with non-randomized control group pretest-posttest design. The sample was taken by purposive sampling technique. This research was conducted at SMAN 7 Bekasi with the subject of the research are studenst of X MIA 3 as the experimental class and the X MIA 1 as the control class. Data collection techniques were a multiple choice objective test to determine students's cognitive abilities. The cognitive abilities that will be examinde according to Anderson taxonom. Based on the result of hypothesis test (test-T) with a significance level of 5 % and dk = 86 obtained t count at 6.11 and t table at 1.671, so that it can be seen that H o is refused and H 1 is accepted. It can be concluded that the multiple representation approach give a positive effect on students' cognitive abilities.
