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.

This study aims to determine the ability to think creatively mathematically junior high school students in Ngamprah village with indicators of students' creative thinking ability used is fluency (fleuncy), flexibility, originality and elaboration. the ability to think mathematically creative is the ability to think that aims to create or find new ideas that are different, unusual, original that brings definite and precise results. This research was conducted to 33 students in one of Junior High School in Ngamprah Village by using qualitative descriptive method. Instrument used in the form of 5 items about the ability of students' mathematical creative thinking on the matter of building a flat side room with interviews to students. The conclusion of this research is the ability of mathematical creative thinking of junior high school students in Ngamprah village is still very low.

This study aims to determine the increased ability of mathematical generalization and self-confidence of students junior hight school with Methaporical Thinking approach. The research method used is an experimental method involving 2 classes, namely experimental class and control class. The sample of this study was chosen randomly with the number of samples were 30 students of class XII at SMP RAHAYU. And elected class 7-1 as experimental class and class 7-2 as control class. In each data collection each student will be given the same pretest and postes. Intrument used is a test of mathematical generalization ability and scale of confidence. From the calculation and hypothesis test, it can be concluded that the improvement of mathematical generalization ability of the experimental class is significantly better than the control class, then most of the students who get the learning with methaporical thinking had better self confidence than ordinary learning.

The aims of this research is to know the influence of cooperative learning think-talk-write (TTW) to students' mathematics communication skill. This research was conducted on one group that is class VII-C in MTs Negeri 1 Kota Cimahi. This research method used pre-experimental one group pretest-posttest design. Analysis of this research data using paired sample T-test and independent sample test T-test. The results of this research are 1) the significant influence of cooperative learning TTW on mathematics communication skill of male students and female students, 2) no difference between the achievement of mathematics communication skill of male students with the achievement of mathematics communication skill female students.

This study aims to determine the ability of students mathematical communication skills of junior high school students in the material of One Variable Linear Equation and Inequality. The study was conducted on seventh grade students in one of the junior high schools in Cimahi as many as 37 students who were taken 6 random samples based on the results of the location of errors done by students in different criteria according to Watson's error. The research approach used is qualitative with descriptive method. The instrument used is a matter of mathematical communication that has been validated. Tests carried out by students were examined for the type of error based on the Watson category and an analysis of error answers was carried out. The results showed that based on the percentage of the types of errors students who had completed mathematical communication problems based on the category of errors according to Watson were incorrect data / ID errors included in a small error of 21%, improper procedure errors IP) is included in a high error of 46%. Omitted conclusions (OC) fall into a fairly low error of 3%. Errors in data missing (ommited data / OD) which is equal to 21%, Error hierarchical problem (SHP) problem is 7%. While conflict response levels (response level conflict / RLC), indirect manipulation (UM), and also errors other than the seven above other / AO) are 0% each, including very low errors.

Extracurricular activity is an activity related to co-curricular and intracuticular in school. One of the main objectives of this extracurricular activity as a place for students who have the interest to follow the activity. This activity can form a positive attitude of students. This study aims to determine the effect of extracurricular activities on the ability of students' mathematical understanding in SMP Negeri 1 Ngamprah. The research method used is a quantitative method with the help of IBM SPSS Statistic 24 applications. The sample used in this study is the students of class VIII SMP Negeri 1 Ngamprah who follow extracurricular and do not follow extracurricular. Students who follow extracurricular become experimental class and students who do not follow extracurricular become control class. The results of this study are the ability of students' understanding of mathematics in SMP Negeri 1 Ngamprah who follow extracurricular and do not follow extracurricular have significant differences. Students who follow extracurricular activities have a better understanding of mathematics than students who do not follow extracurricular activities. Seen based on the existing data obtained the average of the experimental class is 41.8 and the control class 34.4. It gives some influence to the students' comprehension ability that is, giving positive values and good personality for the students, such as thinking creatively and wisely in determining the action, attitude, and decision.
