Validity of React Model Based Learning Devices to Improve Mathematical Communication Ability

This study is a pre test-post test experiment with control group design having a goal to analyze the role of scientific approach on students’ mathematical communication ability (MCA) and self confidence (SC). The study involves 46 eleventh grade Vocational School students, a mathematical communication test, a mathematical self confidence scale (MSC), and a perception on scientific approach scale. The study found that on MCA and its Normalized Gain (N<G>), students getting treatment with scientific approach attained better grades than the grades of students taught by conventional teaching, but both student’s grades were still at low-medium level. On MSC, there was no different grades between students on both teaching approaches, and those grades were at medium level. The other findings, there is no association between MCA and MSC, and students performed high perception toward scientific approach.

This research aims to describe the students’ mathematical communication ability by using cooperative learning talking stick type. This research conducted at one of junior high school in Asahan-North Sumatera- North Sumatera. This research used posttest experimental class design as the method to obtain data. The indicators used to measure mathematical communication ability in this research arranged in three, as follows: 1) the ability of explaining a mathematical problem into figure; 2) the ability to explain mathematical problem situations by own words; 3) the ability of stating a mathematical problem in writing into mathematical models and doing calculation to solve the problem. The result found from this research is there are the differences in the students’ way of answering the problem even though the learning model and the instrument used is same.

The main purpose of this study to investigate the ability of mathematical communication ofHigh School Students, as a result of learning mathematics through application RealisticMathematics Education (RME). Research design used was a quasi experimental. Subjects inthis study consisted of 70 students of class VII Junior High School, Junior High School on oneof the states in Bandung academic year 2015/2016. Subject determined by purposivesampling techniques, and this study using pretest-posttest design of the control group. Datacollected with a mathematical communication ability test descriptions. Data were analyzedusing parametric statistical tests which is Test Independent Sample T-Test and nonparametrical tests which is Test Mann-Whitney. The results showed that: (1) students wholearn math with RME approach has a better ability mathematical communication of studentswho do not learn math with RME; (2) increasing mathematical communication ability ofstudents who learn with RME better than students who do not learn with RME; (3) students'attitudes toward learning mathematics through RME showed a positive attitude.

This study aims to determine (1) the mathematical communication ability of students taught by the gallery walk type cooperative learning model is higher than the mathematical communication skills of students taught by conventional learning models (2) student responses through the application of the gallery walk type cooperative learning model to communication skills. mathematics students of SMP Negeri 8 Padangsidimpuan. The research method used is quasi-experimental. The population of this study were all seventh grade students of SMP Negeri 8 Padangsidimpuan. Sampling using simple random sampling. The sample is class VII-2 as the experimental class and class VII-1 as the control class. Data collection using a mathematical communication ability test sheet.The results showed (1) t_(count )= 3.56 and t_(table )= 1.67 or) t_(count ) > t_(table ) so that it can be concluded that students' mathematical communication skills are taught by cooperative learning model type gallery walk is higher than the mathematical communication ability of students who are taught by conventional learning models. (2) Based on the results of student responses, an average score of 3.55 was obtained so that it can be concluded that student responses through the application of the gallery walk type cooperative learning model to the mathematical communication skills of SMP Negeri 8 Padangsidimpuan students were very positive.
