Abstract

The purpose of this study is to determine the application of make a match learning model can improve students' understanding in the material set.This research is a Classroom Action Research (CAR). The subjects of this study were the students of class VII A SMPN 2 Kalimanggis District Kuningan academic year 2016/2017. The study was conducted collaboratively between researchers, observers, and subjects studied. Implementation of this research is done in the even semester of the academic year 2016/2017. This classroom action research process is conducted in two cycles, each cycle consists of four main actions: planning, action implementation, observation, and reflection. The end of each cycle is tested using question instrument. The test used is a description test performed at the end of cycle I and cycle II. Besides as an evaluation tool, this test is conducted to know the students' understanding. Data processing techniques student learning outcomes are performing tests, collecting test results, correcting test results, scoring the acquisition of test results, determining the value of test results and determining the average value.The results showed that the average value of learning outcomes in the first cycle to get the value of 75 and the second cycle of the average value of learning outcomes increased to obtain the value 87. Similarly, the results of student activity observations showed an increase. In the first cycle of participation and activity of students is 60% and in the second cycle of participation and student activity increased to 80%, so most of the participation and activities of students categorized well. While the results of teacher performance observation obtained the value of implementation aspects of observations in the first cycle of 80% and in the second cycle managed 100%. This study concludes that make a match learning model can improve students' comprehension ability in Mathematics subject in the material set.

Abstract

Improving Student Mathematical Communication Ability.This study used a description test instrument to evaluate students' mathematicalcommunication abilities and used student response questionnaires to find out howstudents respond to the applied learning. To compare the ability of the two classes theresearcher uses one-way t test for two independent samples, Meanwhile, to analyzethe hypothesis of the class gain experiment, researchers used one sample t-test.From the pretest result it was known that the mean score of the experimental class was 4,57 and the control class was 3,79. Through the t-test at that value it is known that thitung = 1,86 while at 5% freedom degree and dk = 86 is known ttabel = 1,99. From both data it was known that -1,99 ? 1,86 ? 1,99 then it meets the acceptance criteria of H0. It means both classes have the initial ability of the same mathematical communication. Meanwhile, from posttest result it was known that the average of experiment class score was 11,53 and control class was 7,57. Because the posttest scores of the experimental class and homogeneous controls, then the comparative test was performed by the t-test. From the t-test it was known that thitung = 3,81 and ttabel = 1,67. From both data it was known that thitung ? ttable then thitung was not available in the reception area H0. This means that after the treatment of students' mathematical communication abilities, the experimental class was better than the control class. The improvement of mathematical communication ability of experimental class students were in the medium category. In addition, from the results of questionnaire responses of students, it was known that students showed a positive response to the probing-prompting learning model.

Abstract

Application Of Cooperative Learning ModelType Think Talk Write In An Effort To Increase Mathematical Communication Skill.This study aims to examine the improvement of students' mathematicalcommunication skills with Think Talk Write model. This research involvesexperimental class and control class which is taken from class VII (Seven) SMPNegeri 1 Lebakwangi academic year 2016/2017. From the results of the pre-testknown that mean score of the control class was 9,53 while the experiment class is16,85. While the result of the post-test show that the mean of the control classes skorare 26,12 then the mean of the experiment classes score 29,75. The data that gettingfrom post-test doesn’t come from the normal distribution, so this dara was comparedby using Mann-Whitney (U) test for large samples. From the analyze, we know thatzcount = 0,43 dan ztable = 1,64. From both of data we know that 0,43 < 1,64. It meansthat after treatment the experiment classes student’s of mathematical communicationmore than control classes. The improvement of the mathematical communicationability of the classroom is not in addition to the result of the student responsequestionnaire, it is known that the students show neutral response to the learningmodel Think Talk Write.
