Communication is the foundation of every learning activity. Mathematical communication is a skill to represent ideas in mathematical language so that it is understood by others who are used in problem-solving activities. This study aims to improve mathematical communication skills by using open-ended student worksheets in algebra. The research sample involved 6 junior high schools in Purworejo Regency, Indonesia which is divided into 2 groups, the experimental group consists of 91 students and the control group consists of 96 students. The study design used a randomized static group comparison design. The research instrument used 5 item essay tests that contained non-routine problems. The data analysis technique used an independent sample T-test. The results showed that the communication skills of students who were subjected to learning using open-ended student worksheets were better than the communication skills of students who were subjected to learning using student worksheets that are commonly used by teachers. These results provide an important impact that teachers should always integrate the presentation of non-routine problems in the form of worksheets as an integral part of mathematics learning.

ABSTRACTThis research is motivated by the fact that the ability of mathematical communication in Indonesia is low. The models and approaches used in the learning process are one of the supporting factors for learning mathematics in the classroom. This study aimed to analyze SMA 1 Namlea students' mathematical communication skills with realistic mathematics learning assisted by GeoGebra. The research method used is quasi-experimental. WHO researched SMA Negeri 1 Namlea, Buru Regency. The analysis results show that the test instrument is valid and reliable to be used for pretest and posttest. The results showed that the mathematical communication of students who received realistic mathematics learning assisted by GeoGebra was better than students who received realistic mathematics learning without GeoGebra. The results also showed that there was a positive response from students towards learning realistic mathematics with GeoGebra.KEYWORDS: Realistic Mathematics, GeoGebra & Mathematical Communication

This research is based on the problems of many elementary students who have difficulty solving math problems especially those related to students' mathematical communication ability. The purpose of this study is to answer the question whether by Think-Talk-Write method (TTW) can develop student self confidence. The research method used is Classroom Action Research, which consists of 3 learning cycles, each cycle consists of 3 actions. Population in this research is grade 6 student of SD in Bandung City. The instruments used include students' mathematical communication skills such as stories, questionnaires, observation guidelines, interviews and documentation. The quantitative data obtained were analyzed using SPSS 19, while the qualitative data used Miles & Huberman technique. The results showed that there is an increase in self-confidence of students with learning Think-Talk-Write method (TTW). The recommendation in this research emphasizes the learning of Think-Talk-Write method (TTW) as one of the alternative learning method that able to give good benefit and stimulation to the ability and confidence of elementary school students in mathematics learning in accordance with the stages of cognitive development of students.

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.

The purpose of this study is to examine:  Improvement of mathematical communication skills of students who obtain Gerlach and Ely learning is better than mathematical communication skills of students who obtain conventional learning, The relationship between students' initial mathematical abilities with Gerlach and Ely learning towards communication skills mathematical, but the relationship between students' mathematical communication skills with student mathematics learning outcomes. This research is a semi-experimental research. The population of this study were all IT students Baitul Quran Langsa, amounting to 22 students where 15 students were in class VII and 7 students were in class VIII. Then the two classes are given different treatment of the learning model. The experimental class was treated with Gerlach and Ely learning and control classes with conventional learning. The instrument used consisted of: a test of mathematical communication skills. The instrument was stated to have fulfilled the content validity requirements, and the reliability coefficient was 0.87. Data analysis was performed with the t-test statistical test, bivariate correlation test and 2-way anova test. Based on the analysis results obtained by the results of the study are:  an increase in mathematical communication skills of students who get Gerlach and Ely learning better than students who obtain conventional learning,  there is no interaction between learning with students 'initial ability to increase students' mathematical communication skills, there is a positive relationship between students' mathematical communication skills and student mathematics learning outcomes. Descriptively the answers to the problem formulation were also examined, namely: the process of solving students' answers whose learning with Gerlach and Ely learning was neater and more complete based on indicators of mathematical communication skills compared to students who used conventional learning. Based on the results of the study, the researchers suggest: Gerlach and Elypada learning of mathematics to improve students' mathematical communication skills can be used as an alternative to applying varied and innovative mathematics learning.

This study was conducted to know the effect of applying Peer Review Strategy on the students’ achievement in writing descriptive paragraph. It was conducted by using experimental research method. This research design was conducted pre-test, post test in experimental and control group. The population of this research was the eight (VIII) grade students of SMP IT IQRA’ Medan. The sample of this research was taken by lottery technique. They were in class VIII-1 by experimental group and the class VIII-2 by control group. The experimental group was taught by using Peer Review Strategy while the control group was given no treatment. The instrument used to collect the data was writing essay test. The data were analyzed by using t-test formula. The result showed that the value of t-observed was higher than the value of t-table. (3,55 > 2,05 (a = 0.05)) with the degree of freedom (df) = 28. It means that there was a significant effect of applying Peer Review Strategy on the students’ achievement in writing descriptive paragraph. So, the alternative hypothesis (Ha) was accepted.

This research aimed to determine the effectiveness of the Cooperative Problem-Based Learning (CPBL) Model in Learning Statics. The experimental class's research method was experimental, in which the experimental class was applied with the CPBL model, and the control class was applied with conventional models. A simple random sample carried out sampling for the experimental group and the control group. The instrument used was the learning outcomes test. The findings show that the experimental group's student learning outcomes are better than those of the control group. Thus, there is an increase in learning outcomes, and student effective results on the CPBL model in statics learning are in a very good category. It is concluded that the application of the CPBL model is more effective than conventional learning.
