Application of accelerated learning method to improve the ability of students mathematical representation

One of the mathematical skills that must be possessed by students is the ability of mathematical representation, therefore the applied learning method should be able to facilitate the students to learn to represent the mathematical ability they have. The purpose of this study to determine the improvement of students' mathematical representation in mathematics learning using accelerated learning method. The research method used is Quasi Experiments with Nonequivalent (Pretest and Posttest) design of Control Group Design. The population in this study is the students of grade X in Pasundan Majalaya Senior High School by using Purposive Sampling technique. The samples involved in the study were 48 students of Pasundan Majalaya Senior High School, 24 students came from class X MIPA 1 (experimental class) and 24 students came from class X MIPA 3 (control class). The learning method is applied to the students of class X MIPA 1 is the method of accelerated learning whereas in the students of class X MIPA 3 is conventional methods. The result of mathematical representation of students 'mathematical representation shows that there is an improvement of ability for students' mathematical representation with gain value of 0.56 with middle criterion for class X MIPA 1 and 0.17 with lower criterion for class X MIPA 3.
