Abstract

The research is motivated by  students’ understanding of mathematical concepts that still low and the material that students have was lost from their mind. This reserach is to determine wether students’ understanding of   mathematical concepts  by using a strategy Hollywood square Review better than students’ understanding of mathematical concepts by using conventional strategy at VIII Grade of SMP N 1 Koto Baru. Type of this research was experiment. Population in this research was students at VIII grade of SMP N 1 Koto Baru, and sample of this research was students class VIIIA as experimental class and VIIIc as control class. Post-test was as instrumentation in this research, with realibility 0,88. From the data analysis get mean score from students’ achievement in experimental class was 66,22 that high  rather than in control class that was 35,68. data analysis was done by using hypothesis testing. Tcalculated= 4,15 and ttable= 1,65. so, we can conclude that students’ understanding of  mathematical concepts that used Hollywood Square Review better that conventional strategy  at VIII Grade of SMP N 1 Koto Baru

Abstract

This research was conducted based on the fact that the students’ understanding on mathematics concept was still low and the students prefer to study in group, but the result is not appropriate with expectation. This research was aimed at revealing whether the use of cooperative learning Numbered Heads technique could improve the second year students’ understanding on mathematics concept better than that of conventional learning. Type of this research is experimental research which using Random subject as research design. The populations in this study were eighth grade students of SMP 28 Padang academic year 2013/2014. By using technique of Random sampling, the sample was selected the class VIII4 as experimental class and VIII6 as control class. This study used post-test as instrument to measure the students’ understanding mathematical concepts. The form of post-test is essay with a reliability r11 = 0,87 . The data analysis technique used t –test by using MINITAB. Based on the analysis of the data found that the two classes are normally distributed and homogeneous samples at the level of 95 % with α = 0.05 . Hypothesis test results obtained P - value equal to 0.015 means less than α = 0.05 , then the hypothesis in this study received so it can be concluded that the students understanding of mathematical concepts by using cooperative learning Numbered Heads technique is better than student understanding of mathematical concepts by conventional teaching class VIII SMP 28 Padang

Abstract

This research is based on the lack of the students’ comprehension of mathematical concepts and the students’ low achievement of mathematic at class IX SMPN 10 South Solok academic year 2013/2014. The purpose of this research is to find out whether the students’ comprehension ability of mathematical concepts by Quick on the Draw technique is better than Conventional technique does. The design of this research is experimental. The population is the students of class IX SMPN 10 South Solok academic year 2013/2014. Technique of selecting sample is randomly. As a result, IX2 is experiment class and IX1 is control class. The instrument that is used is testing with indicator of concept comprehension ability. The testing contains 9 items with high reliability (0.89). The students’ score is analyzed by using t-test one tail. It is found that ttable(1.67) <tcalculated(5.44). It means that the hypothesis is accepted with significant value 95%. This can be concluded that the students’ comprehension of mathematical concept by quick on the draw technique is better than the students’ comprehension of mathematical concept by conventional technique at IX class of SMPN 10 South Solok academic year 2013/2014.

Abstract

The research of this background is based on the students understanding of mathematical concepts have minimum level, in pre-teaching,  the teacher do not generate interest of the students and do not give motivation to the students, students tend to be passive and reluctant to ask. The aims of This study is to determine whether students understanding of mathematical concepts by applying the Learning Cycle models are better than student understanding of mathematical concepts by applying conventional learning in class XI students of SMA Negeri 15 Padang. Type of this research is experimental research, the researcher choose the sample of research using Random Subjects . The population of this study was four class of XI IPA students of SMA Negeri 15 Padang academic year 2013/2014. The sample was IPA2 class as the experimental class  and class XI IPA1 as the control class. The Instruments that used in this research is a test of understanding mathematical concepts. Based on the analysis of the data found that the two classes are normally and homogeneous samples at α = 0.05 and the results obtained from testing the hypothesis P-value = 0.007 means less than α = 0.05, so it means that the hypothesis in this study is received . It can be concluded that the students understanding of mathematical concepts that apply the Learning Cycle Model with taped questions better than students understanding of mathematical concepts by applying conventional learning in class XI student of SMA Negeri 15 Padang.
