Abstract

The background of this research is the students’ mathematical concept understanding that is still low. The purposes of research are to know how the development of the students’ mathematical concept understanding is and to know whether the students’ mathematical concept understanding by applying the cooperative learning model of Think Pair Share type with quiz is better than that by using the conventional learning. The type of research is an experimental research with Random to Subject design. The population of research is the grade-IX students of SMPN 7 Pariaman of the year 2013/2014. The technique of sampling is applied randomly and the chosen samples are IX.2 as an experimental class and IX as a control class. The instruments used in this research are quiz and final tests of mathematical concept understanding. The form of tests used is essay and the test reliability is 0.89. The technique of data analysis is t-test of one side with MINITAB. Based on the analysis of data, it is known that both sample classes are distributed normally and homogenous at α level of 0.05. The hypothesis tests are indicated that P-value is similar to 0.028, meaning less than 0.05, so that the hypothesis of this research is accepted. Then, it can be summarized that the students’ mathematical concept understanding by applying the model of cooperative learning of Think Pair Share type with questionnaires is better than that by using the conventional learning with trust level of 95%. Quiz look at the development of indikators to classify objects according to the nature of certain properties cantained in the quiz I, III, and IV quiz. Quizzes I progress indikator is 86,22%, quiz III percentage progress indikator is 88,89% and the percentage development indikator quiz IV 90,97%.

Abstract

This motivation of this research is about students’ understanding of mathematical concepts that are low.  The students are lazy to give questions and opinions that the material is least understood. This is looked from the result of students’ mathematics learning at class VIII MTsN Tarusan. The purpose of this research is to know students’ understanding of mathematical concept that applay active learning model type trading places which is more good than students’ understanding of mathematical concept that applay convensional learning at class VIII MTsN Tarusan. The type of this research is experiment research with random sampling. The data analysis uses uji t,    and = 1,645. Because of   . Thus, the hypothesis in this research is accepted. In briefly, student’ understanding of mathematical concept use active learning model type trading places  which is more good than students’ understand of mathematical concept by using conventional learning at class VIII MTsN Tarusan.

Abstract

This research is motivated by the group learning is not optimal and the understanding of mathematic concept the class VII students of SMPN 1 Bayang Utara is low. One of the means for improving the students understanding of mathematic concept is applying the cooperative learning model with NHT type accompanied by quiz. The purposes of this research is to know: 1) how the development understanding of mathematic concept indicators by using this the NHT type accompanied by quiz the class VII of SMPN 1 Bayang Utara , 2) whether the understanding of mathematic concept by using this model is better than using the conventional learning the class VII students of SMPN 1 Bayang Utara. This is an experimental research with Random to Subject design. The population in this research is class VII students of SMPN 1 Bayang Utara of the year 2012/2013, consist of two classes. The sampling technique is total sampling made randomly for determining the samples. So, in VII1 class is selected as an experimental class and the VII2 class as a control. The instrument used valid and reliable tests for the understanding of mathematic concept in the form essay on the convidence interval of 95%. Based on the results of data analysis, the students undersanding mathematic concept  by applying NHT-type cooperative learning model with quiz is better than using the conventional learning the class VII students of SMPN I Bayang Utara of the year 2012/2013.

Abstract

This research was stimulated by the backgraund of lower students’ activity in learning mathematic and their comprehension about the math concept at the class VIII SMPN I IV Jurai of South Pesisir Was Still Lower. The objective of this research are: 1) to know whatever the students’ teaching activity by using active teaching strategy of Firing Line Tipe provided with Handout. 2) To Know whatever the students’ comprehension of math concepety by using active teaching stategy of Firing Line type provided with Handout was better than students’ comprehension of math by using conventional teaching. The type of this research was experimental research was all students at the class VIII SMPN I IV Jurai of South Pesisir period 2013/2014 consisted four classes. Technique of taking sample was done randomly by selecting the class was VIII4 as exsperimental class and VIII2 control class. This research used intrument of observation sheets and students’ comprehension of mathematic concept test. This formh of test used essay by reliability test score R11=0,91. Based on the observation result can be concluded that the implementation of active teaching strategy of Firing Line type provided with Handout can improve students’ activity in teaching, especially students Y who work yhe problem from students X have increased from 83% become 95%. The result of hypothesis by using t-test was obtained p-value = 0,002 less than  = 0.05. Thus the hypothes in this research was accepted with the confidence level 95%. Therefore can be concluded that the students’ comprehension about mathematic concept by using active teaching strategy of Firing Line type provided with Handout was better than students’ comprehension of math concept by using conventional teaching model toward student at the class VIII SMPN I IV Jurai of South Pesisir.

Abstract

ABSTRACT This research is caused students low understanding of mathematical concepts are. Because  in learning process is still focus on the teacher . The students still have low ability to explore their idea and to arrange the material . So, one of way to solve this problem is by appliying the ability of Clustering .The goal of this research is to know the influence of clustering toward students understanding of mathematics concepts at grade nine SMPN 4 sutera. Metodology research used experimental research. By using type One Shot Case Study. The population of this research is all grade nine students of SMPN 4 Sutera. In collecting the data by using Sampling simple random sampling, the graden nine (IX2) as experimental class. The final tests is analized by using simple regretion analyze. Thus, the research found the coofesien of corelation r = 0,49. It  means the ability of clustering sampling has influence toward students of understanding of mathematics concepts at grade nine student of SMPN 4 Sutera.

Abstract

ABSTRACT The  background of this research is that the students mathematical concept apprehensions are low and the students like to ask to her friends reather than to teachers. So low students learning out comes VIII-grade of SMPN 1 Basa Ampek Balai Tapan of year 2013/2014. The purpose of this research is to know whether the students mathematical concept apprehensions by applying the snowball throwing cooperative learning model is better than using the conventional learning for the VIII-grade students of SMPN 1 Basa Ampek Balai Tapan. This is experimental research with random to subject design. The population in this research is the VIII-grade students of SMPN 1 Basa Ampek Balai Tapan. The technique of sample classes were determined randomly. The instrument used in this research is test for the mathematical concept apprehension. Based on the result of data analysis, it is know that both sample classes distribute normally and homogenously. So that the hypothesis is accepted, that means that the students mathematical concept apprehension. Using the snowball throwing cooperative learning model is better than that using the conventional learning for the VIII-grade students of SMPN 1 Basa Ampek Balai Tapan
