This study aims: (1) To find out whether the Realistic Mathematics Learning approach influences students' mathematical communication skills. (2) To find out whether the increase in students' mathematical communication skills with the Realistic Mathematics Learning approach is higher than conventional learning. This type of research is experimental research using pretest-posttest control group design. The study population was all VII grade students of YPAK Galang SPM consisting of three classes. The research sample was selected using simple random sampling technique, so that the VII-A class as the experimental class and VII-C class as the control class were obtained with 37 students each. The data used in this study are quantitative data. Based on the analysis of the research data, the following results are obtained: (1) the results of the regression analysis obtained by the equation (Y) Ì‚ = 36,945 + 1,003X. And from the results of the correlation obtained that Realistic Mathematics Learning has a positive effect with a correlation coefficient of 0.944 and a coefficient of determination of 89.1%. So it can be concluded that Realistic Mathematics Learning influences students' mathematical communication skills. ; (2) the results of the t-test analysis with the value of t count = 4.489 and t table = 1.666 which means t count> t table, then the hypothesis Ho is rejected. So it can be concluded that the mathematical communication skills of students taught by Realistic Mathematics Learning are higher than the mathematical communication skills of students who are taught by conventional learning.

    The result of observation shows that the students' understanding of physics science subject is still low. Many teachers still use conventional methods. Students just listen and take notes. Therefore, the use of appropriate and varied learning models is expected to help students in understanding a concept. One alternative of physics learning that can help students understand the concept is through pictorial riddle learning method. This pictorial riddle learning method uses a riddle of drawings on a whiteboard, poster or projected from a transparency then the teacher asks questions relating to the riddle. The purpose of this study is to determine the extent of the influence of pictorial riddle learning method on the understanding of physics concepts class IX students semester 1 SMP Negeri 2 Painan 2015/2016 academic year. Sampling is done by simple random sampling technique. The research population is all students of class IX SMP Negeri 2 Painan. The sample used is class IX-2 as experiment class and IX-3 as control class. The variable in this research is the students' concept understanding on the magnetism materials, with the experimental control group design pre test post test. Data retrieval is done through the test in the form of free description and analyzed using simple regression analysis, coefficient of determination and test of significance in microsoft excel. The results of data analysis showed the relationship between variables expressed in a simple regression equation Y = 51.99 + 0.4286. The value of correlation coefficient 0,5787 with enough criterion (0,5 <r <0,8) value 0,3348 and coefficient of determination equal to 33,5% and> (3,175> 2,015) at significance level 5%, which mean study pictorial Riddle method effect of 33.5% on the understanding of student physics concepts. Thus it can be concluded that there is a positive influence and quite significant method of learning pictorial riddle on the understanding of students' concepts on magnetism materials.

The concrete success of Adiwiyata program is a self-awareness of the surrounding environment in controlling undisciplined habit and taking action as a shared responsibility. The character building using Value Clarification Technique (VCT) learning model becomes a teacher’ alternative in emphasizing students’ activity. This study aimed at analyzing the effect of VCT learning on students’ characters through population density material and humans’ role in the environmental management. The research used quasi-experimental design with nonequivalent posttest only control group design. The population of this study was a total of 293 students of class VII in SMPN 2 Jati Kudus in the academic year of 2016/2017. The sampling used simple random sampling technique. The data of this research were characters of discipline, responsibility, and environmental care obtained from psychological scales instrument and observation sheets, implementation sheets of VCT models, and responses questionnaires of students and teacher. The data analysis techniques used t-test, simple regression, correlation test, and coefficient of determination. The results showed that the VCT learning model had a strong positive correlation to the responsibility character and a moderate correlation to the discipline and environmental care character that could be generalized. Moreover, the results of the correlation analysis and coefficient of determination of VCT learning on students’ characters of discipline, responsibility, and environmental care were 33.2%, 38.3%, and 22.7% respectively. These results indicated that there was another dominant factor on students’ characters.

This study concerned on the influence of constructivism and student self-efficacy approach to mathematical communication. The ability of mathematical communication and self-efficacy of student-controlled students is very important for students. This research sought to examine (1) the influence of learning approach of constructivism to mathematical communicative ability, (2) the influence of student self-efficacy toward student's mathematical communication ability, (3) influence of constructivism and student self-efficacy approach to students' mathematical communication ability. This is a quantitative research employing the pretest-posttest non-equivalent control group design, the population in this study is all Year 7 students of junior high school. Data collection was done by student mathematical communication skills test and student self-efficacy attitude scale. This study found that the use of constructivism and self-efficacy approach significantly influence students' mathematical communication skills and there is no interaction between students’ mathematical communication skills and self-efficacy using the constructivism learning approach.

One of the objectives of mathematics learning is to learn to communicate, because through communication students can communicate ideas, reasoning, and be able to compile mathematical evidence using complete sentences, symbols, tables, diagrams, or other media. One learning model that can be applied to improve students' mathematical communication skills is a group investigation model. This study aims to determine the improvement of students' mathematical communication skills between students who obtain group investigative learning and students who obtain conventional learning are reviewed as a whole and based on the level of students. This study uses experimental research. The design of this study was a pre-test post-test control group design. The population in this study were all seventh grade students of SMP Negeri 9 Banda Aceh. Samples are taken through random sampling techniques. To obtain research data, the instrument is used in the form of tests of students' mathematical communication skills. The results of the study showed that the mathematical communication skills of students who received group investigation learning were better than students who obtained conventional learning both overall and based on the level of students.
