This study is against the background of low students' mathematical communication skills. This study aims to determine the effectiveness of concept achievement model with scientific approach to students' mathematical communication skills in the function material of grade VIII SMP Negeri 1 Berastagi. This research is a quasi-quantitative research experiment. The sample technique used is cluster random sampling obtained class VIII-1 as an experimental class. Indicators of learning effectiveness used by researchers are 1) the quality of learning; 2) the level of learning. This study uses post-test instruments of learning results in the form of essays and observation sheets of teachers' similar teaching with the learning model used. Based on the regression analysis test obtained the regression equation   Y= 16,230 + 0,783X, which means that both variables have a positive linear relationship. For the meaning of the correlation coefficient of communication ability obtained  t table = 2,04 and t count = 16,368  which is the  t count > t table. So the testing of the hypothesis of reject H0 and Ha accepted, then there is a strong and meaningful relationship between the learning model of concept achievement to the mathematical communication skills of students. Then the coefficient of determination obtained r^2= 89,93% means that there is a contribution of concept achievement learning model with scientific approach to the mathematical communication skills of students on function teaching materials by 89.93% so that based on learning quality indicators, the learning model is said to be effectively used. Based on the results of active observations of teacher activities obtained a total average of 4.26 which means the uniformity of teachers teaching with a model of learning concept achievement with a scientific approach is good and effective to the mathematical communication skills of students

Mathematical analytics Important, analytical skills When students are able to understand analysis in physics learning, students will be able to answer questions with questions that are different from the examples given by the teacher. The aim of studying the increased thinking of participants in cognitive taxonomy analysis in Newton's law materials was approved using problem solving learning models. Hypothesis testing is done by comparing the average value of the ability of the initial test (pre-test) and the average ability of the final test (post-test) of students. The process of testing the hypothesis will test the normality and homogeneity test as a requirement to use parametric statistics, namely by using the t-test. Based on the results of the study obtained a value of tcount (8.25) and ttable value at dk = 42 with a 95% confidence level obtained at 2.02. This shows that tcount> t table. So can it be concluded that the expansion of students' thinking analysis ideas on cognitive taxonomy in the legal material used uses problem solving learning models.

From the results of the answers to the test of mathematical communication skills and the deployment of the questionnaire obtained the problem, namely the low capacity of mathematical communication students, the difficulty of students to write the form of mathematical symbols, and the limitations of teaching materials used during learning in class V in elementary school. This study aimed to develop valid worksheets of students (LKPD) on building simple spaces in class V elementary school, knowing the practicality of LKPDs from users, educators and students, and knowing the effectiveness of LKPD on increasing mathematical communication skills. The method of development used in this study referred to the research design of Borg and Gall. Data collection techniques were carried out through documentation, observation, questionnaires, and students' mathematical communication skills tests. The subjects of this study were 25 control class students and 25 experimental class students at SDN 1 Semuli. The study results stated that LKPD products based on the AIR learning model were valid, practical, and effective in improving students' mathematical communication skills. It was proven by material experts, media experts, and language experts validating results with the "Very Valid" category. LKPD based on AIR learning models was practiced to be used by fulfilling the aspects of attractiveness, convenience, and usefulness with the "very practical" category. LKPD-based AIR learning models were effectively used to improve students' mathematical communication skills in the pretest and post-test scores, with the results of the calculation of the experimental class n-gain entry in the category was quite effective
