Mathematical communication skills are very important and is one of the capabilities that should be owned by the students. To create students with good communication skills and meaningful, then used the SAVI approach and realistic approach. This study aims to determine differences in improvement of communication capabilities of students who applied mathematical SAVI approach with computer media and students who applied realistic approach in terms of the level of students' mathematical abilities. To see the interaction SAVI approach to media computer with early ability students (low, medium, and high) to the improvement of communication capabilities mathematical students, to interaction realistic approach to the initial ability of students (low, medium, and high) to the improvement of communication capabilities mathematical students , To describe the differences in the attitudes of students who applied SAVI approach with computer media and students who applied realistic approach. The population in this study were all students of class VII SMP Negeri 1 Nibong North Aceh.Samples were selected VII3 as SAVI class and the class as a class VII2 realistic. Result of analysis shows that there was no difference in improvement of communication capabilities of students who applied mathematical SAVI approach with computer media and students who applied realistic approach. There is no interaction with the computer media SAVI approach with prior knowledge of students (low, medium, and high) to increase students' mathematical communication skills. There is a realistic approach interactions with students 'initial ability (low, medium, and high) to increase students' mathematical communication skills. Students' attitudes toward learning mathematics through realistic approach has a positive attitude score higher than SAVI approach with computer media.

Interest geometry are taught is to develop spatial ability so as to impart knowledge to support other materials. As NCTM specify one of five content standards in mathematics, namely geometry measurement an important element involves the use of visualization and modeling. This shows that modeling is the demands of the curriculum that must be accommodated in the classroom. Therefore, teachers should be able to apply the learning object model that abstracts from geometry into real situations imaginable learners. One lesson that applies the use of models that help learners build their own knowledge is Realistic Mathematics Education (RME). Shaped media selection Information and Computer Technology (ICT) can also meet the demands of the curriculum on the use of visualization to teach geometry. One of ICTs to facilitate learners to imagine something abstract geometry of the object is Cabri 3D software. But in reality there is no learning device that integrates Cabri 3D geometry once using RME approach. This study aims to develop and produce devices RME-assisted learning Cabri 3D is valid, practical, and effective. This research is a research development refers to the model of Dick and Carey consisting of nine steps, namely the identification of learning objectives, learning analysis, identification of the characteristics of learners, formulate learning objectives, develop test items, develop learning strategies, develop learning materials, design and implement formative evaluation, and revising instructional materials. The trial in this study conducted in SMP 19 Pilot Banda Aceh. The result showed that the learning device geometry with Cabri 3D-assisted RME approach memenui valid criteria, practical andeffective.

Every individual basically has the creative potential and creative thinking abilities of students can be improved, so that the teacher needs to know the level of creative thinking abilities of the students in solving mathematical problems and filed. By knowing the level of creative thinking abilities of students the teacher can design methods, strategies and learning techniques to improve students' ability to think creatively. One way to determine the level of students' creative thinking among others, by asking students to solve problems and propose open (open ended). The use of open-ended questions can stimulate creative thinking, original thinking skills, and innovation in mathematics. This study aims to determine the level of students' creative thinking in mathematical problem solving and problem posing through open ended type of questions and the level of creative thinking of students in the filing of mathematical problems through open ended type of questions. This research is a descriptive qualitative data collection using the test method open ended questions and interviews. The subjects were students of class VII MTsN Meureudu. All the study subjects given a test with open-ended questions, the results were analyzed based on three components, namely creative thinking fluency, flexibility and originality, then researchers conducted interviews with six students to confirm an answer and describe the level of creative thinking. The results showed that two students are at level 4 (very creative), a student is at level 3 (creative), and two students are on the 2nd level (quite creative). While the other students do not have the ability to think creatively in solving problems. Three of the six students are on the 2nd level (quite creative), while three other students do not have the ability to think creatively in a posing problem.

The rise of the moral crisis that occurred among students, fuelling disquiet and anxiety of the various elements of the nation. One of the solutions to tackle the problems of the moral crisis is through the character education. This research aims to analyze the efforts of teachers to develop the character of critical thinking and creative thinking of students through the learning of mathematics, and know the relationship of teacher's effort to develop the character of critical thinking and creative thinking characters with student learning outcomes related to the ability of critical thinking and creative thinking. Subjects in the study was a teachers of mathematics class V-2 MIN Tungkop Aceh Besar District. Research data collected through observation and interview against teachers and students as well as through tests the ability of the creative thinking and critical thinking that are given to students. Based on the results of the research it is known that 1) The teacher had been an effort to develop the character of critical thinking and creative thinking of students by providing questions that include critical thinking and creative though not at all meetings, but the encouragement of teachers in order to give students the critical thinking and creative thinking during the learning process still belongs to minimal 2) The ability of critical thinking and creative thinking students of class V – 2 in the category of “Very low”.

The thought process is very important in learning mathematics, especially in problem solving. By knowing the thought process didwa then the teacher can design an efficient learning model. The purpose of this study was to determine the thinking of students MTsN Rukoh Banda Aceh in solving the problem about the story in terms of cognitive style reflective and impulsive. This study uses a qualitative method. This research was conducted in Banda Aceh MTsN Rukoh in class VII. Sources of data obtained from observation, MFFT, tests and interviews. Examination of the validity of the data is done by triangulation of time. Data analysis was carried out through several stages of data reduction, data presentation and conclusion. Based on the results obtained: (1) the thinking of students who styled cognitive reflective as follows: (a) the students are able to understand the problem; (b) the students have been able to make a plan or a way to solve problems and create a relationship between the known data with data asked in question; (c) the student is capable of running plans have been made, by operating the known data on the matter to the steps that have been made, and then execute the plan. Having obtained the results of the plan and then operate on the issues in question; (d) look back at what has been done or checked back in. (2) the thinking of students whose cognitive style Impulsiveness as follows: (a) the students are able to understand the problem; (b) students make settlement by relying intiusi so that the answer given was one of the students to operate on a mathematical concept; (C) the student is capable of running plans have been made, but in running student plan is still lacking precision in understanding the steps to resolve the matter in question; (d) a student can not make a conclusion on the question of.
