<![CDATA[Each person has a different mathematical communication ability. Mathematical communication ability is a person's ability to convey information about mathematical concepts and ideas both in spoken and written form. This study aimed to describe the mathematical communication skills of students of Grade VIII of SMP Negeri 2 Purwokerto based on extracurricular activities. The type of this research was descriptive qualitative. The subjects used in this study were students of Grade VIII B SMP N 2 Purwokerto in the 2019/2020 academic year. Data were collected using the form of tests, interviews, and documentation. The test used in this study was a written mathematical communication skill test. The research subjects consisted of 2 students with academic extracurricular activities, 2 students with non-academic extracurricular activities, and 2 students with both academic and non-academic extracurricular activities. The results of this study indicated that: 1) students who only took academic extracurricular activities and students who took both academic and non-academic extracurriculars were able to present mathematical ideas in the form of images, mathematical symbols, and provide arguments for problems that were presented appropriately, and 2) students who only joined non-academic extracurricular activities, in general, had not provided arguments for a problem that was presented properly, but they were able to present mathematical ideas into the form of images and mathematical symbols appropriately.Keywords: Mathematical communication skills, extracurricular activities.]]>

<![CDATA[The purpose of this study is to compare the results of reliability estimation for multiple choice test instrument with data derived from simple random sampling and stratified random sampling using KR-20 formula and Considering one of disadvantages of a multiple choice instrument is guessing factor, this studi also estimatie reliability by using probability guessing formula as well. The study use quantitative descriptive method,with one way analisys of variance. Data Population is mathematics test results of 69.193 12th grade students fromall over jakarta senior high school wich secondary obtained from BNSP. The results of this study show that, on the same sampling technique,indicates that probability guessing formula estimation are higher compare to KR-20 formula. In terms of estimate reliability with same formula and data derived from different sampling method, indicate even by KR-20 formula or probability guessing formula, estimation of reliability will higher by data derived from simple random sampling Keywords: KR-20 formula, probability guessing formula, sampling technique, simple random sampling, stratified random sampling]]>

<![CDATA[This study aims to determine the increase in learning outcomes of class VIII.F SMP Negeri 2 Kota Bengkulu in the academic year 2017-2018 in solving questions on SPLDV material through the implementation of cooperative learning with peer tutors.The subjects of this study were 34 students of VIII.F of SMP Negeri 2 Kota Bengkulu. Data collected includes: student learning outcomes, teacher observation results, student observation results. This research is a Classroom Action Research (CAR) conducted in two cycles. Each cycle includes 4 (four) stages, namely: planning, action, observation (observation) and reflection. In this study it is said to be successful if at least 75% of students get a value of ≥60.The results of this study shows that the first cycle of learning outcomes is not yet appropriate with the expectation. There are only 55,88% of students who reach completeness. It means that the indicator of success has not been achieved, while in cycle II shows thatlearning outcomes are in line with expectations. There are 88,24% of students who reach completeness. It means that indicators of success have been achieved.Based on the analysis of the research results it can be concluded that through the implementation of cooperative learning with peer tutors can improve the learning outcomes of grade VIII.F SMP Negeri 2 Kota Bengkulu in the school year 2017-2018 in solving questions on SPLDV material. Thus it is recommended that Mathematics teacher associates in the teaching and learning process use cooperative learning models with peer tutors so that student learning outcomes are better. Keywords: learning outcome, peer tutors ]]>

<![CDATA[The comparison of students’ mathematics analogic through cooperative learning think talk write with students facilitator and learning model on class VII MTs NurulHasanahVelage Sungai Gelam districts Muaro Jambi. The comparasion of mathematics analogic through cooperative learning model think talk write with students’ facilitator and explaning learning model on class VII students’ of MTs NurulHasanahVelage Sungai Gelam districts Muaro Jambi.Based on the observation in MTs NurulHasanahVelage Sungai Gelam districts Muaro Jambi, it is found that the mathematic analogi the students are on low category. It can be seen from the students ore on low category. It can be seen from the students test result. This happened because teacher was being so active in the class room, while the students put themselves only as the receiver of the learning material. Based on the problem research, the methode used in this research is experimental research because there is cause and effect between two variables. This research is located in MTs NurulHasanahVelage Sungai Gelam districts Muaro Jambi. The subject of the research is class VII studentsacademil year 2018/2019. The population of the students of class VII MTs NurulHasanahVelage Sungai Gelam districts Muaro Jambi.The result of the research show that the ability of the student in solving mathematics problem with cooperative learning model think talk write: 1) based on the post test, it can be seen that student test result in experimental class by using cooperative learning think type write is 33,7. While the result of control class by using student facilitator and explaining model is 29,9. Based on the result, it can be concluded that student ability in solving mathematics analogy by suing cooperative learning model think type write (ttw) is hinger than student who used student facilitator and explaining model on class vi student of MTs NurulHasanahVelage Sungai Gelam districts Muaro Jambi. Keywords: Mathematics reasoning, TTW, Student facilitaor and explaining]]>

<![CDATA[The purpose of the study was found out the differences in students' mathematical communication skills learning model based on problem learning, the cooperative Jigsaw type and conventional learning model. The learned model which the results was better differences in students' mathematical communication between learning models problem based learning (PBL), the learned models cooperative jigsaw type, and the models conventional junior high school students. This type of the research was quasi experiment. This research was conducted at SMP N 10 of Bengkulu at VIII grade 1st in the academic year 2017/2018. The population of this study was all students of the class VIII consisting of 5 classes. The sample of the research was chosen at randomly that VIII A was given a learning model cooperative jigsaw type, and class VIII D was given a conventional learning model. Mathematical ability of the students gathered with mathematical communication ability test, This test consists of pre-test and post-test. The data was analyzed with one-way ANOVA, followed by BNT test. The results showed that there were differences between students' mathematical communication skills in PBL models,jigsaw models and conventional models. The test was results further suggested was not the difference in the ability of the differences between PBL with Jigsaw. While conventional and jigsaw, PBL with conventional differences.based on the average score of the three models of mathematical communication skills learning, PBL learning model provides results of mathematical communication skills was better. Keywords: communication ability, problem based learning, jigsaw]]>
