The Subject

Students' mathematical communication skills are still unsatisfactory, the average student error shows an error in expressing daily events in the language of mathematics. This is due to a lack of student understanding of the material that has been taught, and the level of students' creativity in recording important concepts contained in the content of the subject matter is still not satisfactory, student records tend to be still boring. The purpose of this study are: (1) to describe the implementation of mind mapping in the scientific approach to improve students' mathematical communication skills, and (2) describe the results of the assessment of mathematical communication skills that occur in students after learning is done with mind mapping in the scientific approach. The type of research that the author is doing is included in classroom action research (CAR). The author uses interview, observation, test and documentation methods. As for the analysis, the author uses descriptive qualitative analysis techniques, namely in the form of qualitative data and quantitative data that the author obtained during direct observation in the field. The research findings show that the application of mind mapping in the scientific approach can improve mathematical communication skills in students of Jambi City Vocational High School 9. (1) The process of implementing mind mapping with a scientific approach to improve students' mathematical communication skills can run smoothly as planned. The application of mind mapping has provided new experiences for students and teachers and provides several benefits, the benefits of mind mapping obtained include: students become the spirit of learning, students easily remember lessons and students gain drawing experience to find the relationship between one concept and another concept and the teacher easier to explain the subject matter to students; (2) on the assessment of students 'mathematical communication skills, from quantitative data the acquisition of scores on students' mathematical communication obtained a high enough value, namely in the first cycle the average value obtained was 75.87 or around 77.2%, in the second cycle there was an increase namely 80.1 or around 87.1%.Keywords: Mind Mapping, scientific approach, and mathematical communication skills

ABSTRACTThis study aims to improve students' mathematical communication skills through the application of cooperative learning model Match Mine on the subject of integers in classVII MTs2 Medan. This type of researchis a classroom action research. The subjects were students of class VII-1 MTs 2 Terra in TA 2014/2015 which amounted to 42students. The object of this research is the students' mathematical communication skills through cooperative learning model Match Mine on  the     subject of         integers. The research instrument used is th eobservation and test mathematical communication skills. This study consisted two cycles and at the end of each cycleis given test comunication is mathematical ability. Before given, test           first      validated to the  validator. The results showed that cooperative learning model in the material Match Mine integer scan improve students' mathematical communication. It is seen from the results before action is given, the provisi on of diagnostics tests of 42 students only as many as 15 students (35.72%), which reached a value ≥ 65 with an average value of 58.18 class. After agiven action, the first mathematical communication skills tests in the first cycle, from 42 students as many as 25 students (59.52%) reached a value ≥ 65 with an average value of 66.95 class. From theanalysis ofthe test data communication capabilities mathematicalI on the second cycle of 42 people found that the students are 37 students (88.09%) reached a value ≥65 with an average value of 74.38 class. Based on observation, learning management research conducted in the first cycle, including both categories with a scoreof 2.87. Furthermore,in the second cycle, the researcher's ability to manage the learning increased to 3.40 so very good category. Based on the above results, it can be conclude edthatby implementing cooperative learning model Match Mine can improve students' mathematica lcommunication on the subject of integers in class VII MTs 2 Medan.
