Peri Nainggolan, 071188830023. The Effect of Approaching Realistic Mathematics and Students’ Learning Motivation on Capability of Student Mathematics Model of Junior High School Students in Lubuk Pakam Academic Year 2008/2009. A Thesis : Mathematic Study Program Post Graduate of State University of Medan 2009.
The objectives of the study are (1) to find out whether capability of student mathematics model using realistic learning approach and expository approach (2) to find out whether capability of student mathematics model of the student with learning motivation higher than that of the students with learning motivation lowly (3) to find out the interaction between the learning approaches and students’ learning motivation with capability of student mathematics model.
The population of the study was student of Grade VIII Junior High School Students in Lubuk Pakam. The sample of the study was 102 students in class VIII.1 and VIII.2 Junior High School Students Neg. 2 Lubuk Pakam; class VIII.1 and VIII.2 Junior High School Students HKBP Lubuk Pakam; and class VIII.1 and VIII.2 Junior High School Students RK Serdang Murni Lubuk Pakam; The samples of the study class each VIII.1 for realistic learning approach, but every class VIII.2 expository learning approach is used. These samples were taken by using cluster random sampling method. The instrument in collecting data of capability of student mathematics model was essay test that consisted of 5 item with reability of 0,675. In collecting data of students’ learning motivation, 30 items test is used adopted from Sembiring to the students. Before data analyzed used at first tested by analysis rules in normality ang homogeneity of data. Normality test was tested using Liliefors test while Homogenity was tested using Bartlett test. The data was analyzed using two ways ANAVA with = 0,05 and the using Scheffe.
The results of the study were: (1) the mean of the capability of student mathematics model of the students who are taught with general by using realistic mathematic approach was = 26,1132 higher than with expository approach was = 23,850 with F observe = 10,6981 > F table = 3,938. (2) the mean of capability of student mathematics model with high learning motivation ( = 28,1731), higher than those learning motivation lowly ( = 21,640) with F observe = 77,8567 > F table = 3,938. (3) there was interaction between learning approaches and learning motivation with capability of student mathematics model with F observe = 8,8654 > F table = 3,938. Based on the result of the study with it is concluded generally that the capability of student mathematics model by using realistic learning approach higher than expository approach. The student characteristic is capability of student mathematics model with high learning motivation higher than higher than low learning motivation and for high expository learning motivation approach is appropriate. The implication of the study is specialized to mathematics teachers, that is applying learning approach. They must consider the student’s characteristic specially learning motivation characteristic.
