Profile of mathematical communication skills junior high school students in problem solving

This research is motivated by the low mathematical communication skills of junior high school students in the city of Bandung Regency. This study aims to determine the comparison of the mathematical communication skills of junior high school students in the city of Bandung regency between the learning usingmodels Think Talk Write. The method used in this study is a quasi-experimental method with a pretest-posttest control group design involving two groups and randomly selected classes, at the beginning and end of the study the two classes were given a test. The population in this study were junior high school students in the city of Bandung Regency, while the sample consisted of two randomly selected classes. Obtained class VII A (experimental class) given themodel Think Talk Write and class VII B (control class) is given a scientific approach. The instrument used was a 5-item mathematical communication ability description test, then theability scores mathematical communication students'were analyzed with descriptive and inferential statistics using the help of SPSS 21 software. Based on the results of the study, it was concluded that there were differences in the achievement of students' mathematical communication skills using models Think Talk Write with students who used a scientific approach.

This article is derived from the research result entitled “The Application of Problem Solving Approach in Improving Junior High School Students’ Mathematical Communication and Disposition Skill”. The research is purposed to see and analyze if there are some improvements in mathematical communication and disposition skill achievement of the students who have been treated using problem solving approach compared to the students who are still treated using conventional approach. The population of the research is all students at a junior high school in Subang regency. Out of these students, 40 students of class VIII D were chosen randomly as the experiment class, and 41 students of class VIII C have also been randomly chosen as the control class. The data in this research have then been analyzed using parametric and non-parametric statistic. The result of this analysis has shown that the achievement of experiment class students’ mathematical communication and disposition skill is better than the achievement of the control class students. The experiment class students’ mathematical disposition is also better than those of the control class. Lastly, the result also shows that there is some kind of correlation between the mathematical communication and mathematical disposition on the level of medium.

Correlational Method

This study aims to analyze in depth the influence of mathematical disposition on mathematical communication ability of junior high school students. The method in this research using a correlational method with quantitative approach. The population of this study is all junior high school students in one of the SMP Negeri in West Bandung amounted to 34 students. Instruments in this study using the test of mathematical communication skills as much as 5 items and the scale of mathematical disposition as much as 23 points of statement scale. The result of this research is student's mathematical disposition influenced by 76,5% then its rest influenced by other factors outside mathematical disposition equal to 23,5%.
