This research is to analyze and analyze the improvement and achievement of students' understanding and communication ability and the independence of junior high school students learning using Reciprocal Teaching approach compared to using ordinary learning. The population in this study is the seventh-grade students of SMP in one school in Bandung. The sample of the experimental class and the control class. The method used in this research is quasi-experiment. Data processing of communication skills and mathematical understanding using a t-test, two-lane ANOVA, and linear regression. The result of the research shows that the achievement and improvement of students' mathematical understanding and communication ability which get the learning using the Reciprocal Teaching approach are better than the students who get regular learning. Students of experimental class with Reciprocal Teaching learning and control class with ordinary learning there is no relation between mathematical understanding ability with student learning independence and experimental class students with Reciprocal Teaching lesson and control class with ordinary learning there is no correlation between mathematical communication ability with student learning independence.

This study aims to determine the improvement of mathematical communication skills of junior high school students from the influence of contextual approach. This research takes the form of a posttest pretest design that compares the influence of a contextual approach with a conventional approach. This study has a population that is all students of SMP class VII in Cianjur District while the sample is a student of class VII SMP Plus Al-Ittihad Cianjur. The samples were taken at random into experimental groups and control groups. Based on the data in the field, it can be concluded that the effect of improving mathematical communication ability of junior high school students who gain learning using contextual approach is better than conventional learning. Therefore, the effect of improving learning with contextual approach is much better while conventional learning is still very less.

Attitudes Towards Learning

This experimental research focuses on improving Junior High School students’ mathematical communication ability through the implementation of teaching math using reciprocal teaching method. The low level of students’ mathematical communication ability has been one of the underpinning reasons why this research was carried out in the first place. The aim of this research is to investigate students who are taught using reciprocal teaching methods show better improvement on their mathematical communication ability compared to those who are taught using conventional methods. In addition to that, this research is also interested in understanding students’ attitudes towards learning math using reciprocal teaching method. The research population is all students of SMP Negeri 4 Cimahi, grade VII. The treated group is from class VII B while the controlled group is from class VII H. Both of the groups were chosen randomly. Based on this analysis, it could be concluded that 1) students’ who were taught using reciprocal teaching method showed higher improvement on their mathematical communication ability compared to students who were taught using conventional methods, and 2) almost all students demonstrated positive attitudes towards learning math when they were taught using reciprocal teaching method.

The ability of mathematical communication is the skill to communicate mathematics that is learned and the skill of using mathematics as a communication tool (mathematical language). Mathematical communication skills are very necessary in learning. Without mathematical communication skills, a person will not be able to deliver statements according to their desire. This qualitative descriptive study aims to describe the level of mathematical communication ability of junior high school students in solving open ended problems with the topic of functional graphs. The method of collecting data through written tests and interviews. Written tests were given to 115 8th grade students of junior high schools in Surabaya, followed by interviews of one student at each level of mathematical communication ability. The results showed 51 people (44%) were at fourth level, 27 people (24%) at third level, 23 people (20%) at second level, and 14 people (12%) at first level. Students at fourth level and third level are equally able to use mathematical language that was accurate and effective, and appropriate in providing the strategies. But it was different in giving the arguments. Students at second level can not provide logical arguments, the mathematical language used was less effective and accurate, and the strategies used were precise but incomplete. Students at first level did not provide the right strategies because the lack of information which contained in the story, did not provide responses more to the stories they have been written, and did not demonstrate the ability to use mathematical language that was  accurate and effective.

Communication Ability

The ability of mathematical communication is contained in the curriculum and objectives of mathematics learning. Through mathematical communication is expected to improve students abilities of mathematical concepts. The purpose of this study is to determine the level of mathematical communication ability of junior high school students on the material system of two linear equations. This research is a descriptive research with qualitative approach. The study time was held in the even semester of the academic year 2017/2018. The subjects of the study were students of SMP class VIII in Cimahi city as many as 33 students. Data collection methods used are test methods, observation and documentation. Based on the results of data analysis showed the students mathematical communication ability of SMP on linear equation system two variables were obtained: (1) students ability in reflecting real objects, drawings and diagrams into mathematics idea with percentage of 81,08%; (2) students ability to explain ideas, situations and mathematical relations both orally and in writing using real objects, images, graphs and algebraic expressions with percentage of 33,33%; (3) the ability of students to declare daily events in language or mathematical symbols or to construct an event mathematical model of 18.18%; (4) students ability in explaining and making math questions studied for 7.58% and (5) students ability in making conjectures, formulating arguments, formulating definitions and generalizations of 7.58%.
