This research aims to look at the difference in the ability of mathematical creative thinking in students, through Realistic Mathematical Education learning or RME and through conventional learning. The research design used was an experiment, namely in the form of a test of the ability of creative thinking. The population in this study of Junior High School students throughout the country, namely in West Bandung Regency. Sample research VIII grade i.e. in one of the Junior High School in West Bandung chosen at random and selected class A (grade experiment) that uses learning Realistic Mathematics Education (RME) and class B (grade control) that uses regular or conventional learning. The research results showed that the p-value of 0.000 < critical limits. Thus, the ability of mathematical creative thinking of the students who got the learning with Realistic Mathematics Education better than the students who got conventional learning.

The purpose of this study was to find out how the mathematical communication skills of students in solving the problem of flat building of class VII triangles in one of the SMP in the city of Cimahi. Data collection uses written tests for 33 students. The research method used is descriptive qualitative research that is analyzing students' difficulties in solving mathematical communication skills on indicators stating everyday events and lowering the quadrangular flat building area formula of grade VII students of junior high school. The results of this study can be concluded that there are 6.06% (2 students) who have excellent mathematical communication skills, 93.94% (33 students) have good mathematical communication skills and 0% (no students) who have communication skills mathematically is not good at problem 1 which indicator states everyday events and decreases the formula of quadrilateral flat building. This is due to the lack of ability of students to communicate their ideas so that they cannot solve problems in the given questions and even if asked they can only smile and be quiet.

The purpose of this study was to analyze the problem solving skills of junior high school students based on student gender. This research is descriptive qualitative. Data from the research results obtained from the results of writing written questions and the results of oral interviews of 14 students of class VIII from Waringin Middle School, Bandung. The instrument used is 3 numbers of material questions that are in accordance with indicators of cognitive aspects. The results of this study indicate that from the problem description given and from the results of interviews about problem solving abilities of junior high school students with female gender on average, it is better than the problem solving ability on average junior high school students have a way to solve while solving problems. So that researchers can conduct research using active student learning methods to get better results, and also be able to understand other factors related to problem solving problems of junior high school students, both male and female students.

This study aims to determine the mathematical connection skills and confidence of junior high school students. With the background of the low mathematical connection skills and self-confidence of students, this study was conducted. The method used for analysis in this study is a Descriptive Qualitative Method that aims to be able to analyze the results of students 'work on the questions of students' mathematical connection abilities and questionnaires to search for confidence in students of SMP Bina Harapan Bangsa. The subjects studied were 1 class of students, amounting to 37 students in class IX-B of Bina Harapan Bangsa Middle School in Bandung Regency. The test questions used are mathematical connections with the questions given as many as 3 questions and non-test instruments for students' self-confidence. The results of the analysis obtained are the mathematical connection ability of students in junior high schools in the district of Bandung based on written description tests are still relatively low. But students already have good confidence in learning mathematics.
本研究旨在探讨初中生数学联系技能与自信心的关系。本研究是在学生数学联系能力和自信心较低的背景下进行的。本研究使用的分析方法是描述性定性方法，旨在分析学生在学生数学联系能力和问卷调查问题上的工作结果，以寻找SMP Bina Harapan Bangsa学生的信心。研究对象为万隆县比那希望邦沙中学IX-B班1班37名学生。试题采用的是与题目之间的数学联系，题目最多提供3道题，并使用非测试工具来增强学生的自信心。分析得出的结果是，万隆区初中学生的数学连接能力基于书面描述测试仍然相对较低。但是学生已经对学习数学有了很好的信心。

Based on the analysis, the mistakes made by students in doing the mathematical understanding problems on the material on the flat side room on the indicator of applying the concept or problem-solving algorithm only reached 21% and the average percentage of students' mathematical understanding ability is 39%. The question instruments used are questions that have been tested for reliability, validity, differentiation and difficulty indexes have also been validated by expert validators. The mathematical disposition of junior high school students on the material of the flat side room is 49%. The lowest percentage is in the indicator has a sense of interest that affects other indicators. The research method used qualitative descriptive analysis to find out how far the achievement of indicator of mathematical understanding ability and to know the level of category of mathematical disposition at each item statement. Based on the results of the overall research that the achievement of indicators of mathematical understanding ability has not been fully achieved and the ability of students disposition is low.

This research examines the learning of mathematics-learning cooperatives the type of Team Assisted Individualization with contextual approach and it is relation with improved mathematical connection quality of high school (Junior High School) Private in the city of Bandung. The purpose of this research was: know how to increasiing learner mathematical connection quality who follow the method of contextual approach Through Cooperative Learning the Type of TAI compared with students who follow the teaching of mathematics with the conventional models, implementation approach contextual approach in class and the difficulties faced students of middle school in solving about the connection mathematics. The study instrument apply was a black-and-white exam mathematical connection quality. The results obtained in the form of the pretest and posttest scores then processed with statistical methods test the difference of two averages. The output indicate that improvement of connection quality of middle school student who follow the method of contextual approach Through Cooperative Learning the Type of TAI is more increased compared with students who follow the teaching of mathematics with the conventional models. Implementation contextual approach can improve the ability of connection mathematics students middle school, the difficulties faced students middle school in solving about the connection mathematics is indicator using math in the part of another study or in daily life.
