This research seeks to explore and reveal students' mathematical problem solving abilities by analyzing student answers. The research subjects were seventh grade students taken from a public junior high school in Purwakarta Regency. The results of the study show that students' mathematical problem solving ability is still very weak and far to be complete even though the level of difficulty of the instrument is in the medium category. In general, the ability of these study subjects in mathematical problem solving is still below 50%. It is time for teachers to apply problem-based learning, in addition to conventional learning models, to provide opportunities and experiences for students to see and experience mathematical problem solving in the classroom. This qualitative study exposes students' responses in dealing with story questions in a rectangular building material. In addition the students are given the questions shown to reveal whether the students are using a systematic solution or can answer directly without a sequence, judging by the ability to solve mathematical problems. There were 6 heterogeneous students who were the subjects in this study. Based on the analysis that has been done, the results obtained are (1) students answer the problem is not systematic, (2) lack of understanding of the sequence of problem solving, (3) students are too hasty in doing math problems.

The purpose of this study is to examine how the relationship between the ability of mathematical understanding with the independence of student learning in learning using a contextual approach. The method in this research is quasi-experimental method, with two different classes taken, where the first class get learning with contextual approach and second class using ordinary learning. The population is all students in one of the cities cimahi with samples taken two classes. Both classes were given pretest and early questionnaires to determine their initial ability, then in the experimental class were given learning with contextual approach and control class were given regular learning, and at the end of both classes were given postes and also final questionnaire, which the data at the end will be in though and in the correlation analysis using Product Moment Pearson. The results showed a significant relationship between the ability of mathematical understanding and student learning independence in learning mathematics..

The ability of mathematical connections is an essential skill that must be mastered by high school students, as it will help master understanding of meaningful concepts and help solve mathematical problems through the interrelationship between mathematical concepts and between mathematical concepts and concepts in other disciplines even with applications in real-life students. This study aims to examine the ability of mathematical connections of students in one junior high school in Bandung on Social Arithmetic materials. The method used in this study is descriptive qualitative, with the subject of research is 36 students of class VIII in one of the State Junior High School in Bandung. Instrument given in the form of description test as much as 3 problem each representing indicator ability and analyzed so that get data fulfillment indicator ability of mathematic connection. Based on the data analysis, the students 'mathematical connection ability is still low, so it is necessary to design the learning activities that can facilitate students' mathematical connection ability.

The research objective is to examine the achievement of mathematical critical thinking capacity of students applying the CTL approach with a comparison of students applying ordinary learning and examining the extent to which the increasing capacity of critical thinking in mathematics students apply the CTL approach to the comparison of students who apply ordinary learning. The study population was all junior high schools in West Bandung regency, were chosen arbitrarily and were selected by Darul Hikmah Junior High School. The sample is taken by any selected class of class 7-A as a research class, and class 7-B as a review class. The research class is given a learning model with the CTL approach, and the review class is given an ordinary learning model. The research instruments used in mathematical critical thinking capacity tests take the form of descriptions. Data processing increases the capacity of critical thinking mathematically by applying tests that distinguish two means using IBM SPSS 23 software. Data from the analysis showed that the achievement and improvement of the critical thinking capacity of the mathematics of the participants who were given the learning method using the CTL approach was better than those of the participants who were given the usual learning method.

This research is motivated by the importance of mathematic critical thinking ability for students and the low ability of students matematics critical thinking. The population in this study were all students of SMPN 2 Cimahi class VII, while the sample was students of class VII-7. Then through observation and interview determined 6 students as research subjects. The method used in this study is analytic descriptive. The research instrument is 5 essay questions that represent indicators of mathematic critical thinking ability. The results showed that the average achievement of students in each indicator was less than 50%, which means it can be concluded that students' critical thinking skills are still relatively low.
