This study describes the ability of mathematical connections. This study is a qualitative descriptive research with the subject of research as many as 27 students of class IX SMP Negeri 01 Cipongkor West Bandung regency. Subject given a written test in the form of an instrument about the connection consisting of eight items. After that, researchers conducted interviews with selected subjects. From the result of student completion and interview, it is found that the level of mathematical connection ability of junior high school students is still low. This is seen from the mistakes that students do in solving the problem, where students actually already understand the problem quite well as can mention the elements that are known and asked. However, students are less conscientious about how the relationship between the data is known and what is asked. So that students are wrong in choosing the right strategy in the settlement. In addition, this is also influenced by students' lack of understanding in the application of formulas. The errors are caused by several factors, including students are less understanding of the material and students are not able to transform the issues submitted into the knowledge it has.

The background of this research is that the situation in the field shows that the pythagorean theorem material is an abstract material, complicated, and requires precision in calculating using formulas. The purpose of this study is for learning learning using the PBL model (Problem Based Learning) in the Pythagoras theorem material. The method of this study used the exeriment method with the design of the pretest-posttest group, the subject of this study was class VIII of SMP Negeri 2 Campaka Mulya which produced 32 students consisting of 20 males and 12 females. The instruments used are tests and non-tests. Data collection tools are RPP Learning Implementation Plans, Observation Sheets, and Test Sheets. Based on the results of class VIII tests before using the PBL model in pythagoras lotus material obtained an average value of 53. And the results of class VIII tests after using the PBL model on pythagoras teorema material scored an average value of 75. and after the application of the PBL model Based on teacher observation and students in the implementation of mathematical learning in the material of the pyhtagorean theorem can be concluded to run well. 78% and 75% student activities are carried out.

This study aims to determine the mathematical problem solving ability of SMP class VIII students in solving story problems on the material of a two-variable linear equation system (SPLDV). This research is a qualitative descriptive study. The subjects in this study were 20 grade VIII students at SMP Negeri 2 Haurwangi. The data collection technique used a test technique in the form of descriptive questions, totaling 4 questions and each question representing each indicator of mathematical problem solving ability. The instrument used in this research is in the form of a test of mathematical problem solving ability on the material of linear equations of two variables. Based on the results of the study, the results of the mathematical problem solving ability of students who had low mathematical problem solving abilities were 8 students (40%), the category of moderate mathematical problem solving ability was 7 students (35%) and the category of high mathematical problem solving ability was 5 students (25 %). It can be concluded that the mathematical solving ability of SMP class VIII students in solving story problems on the material of linear equations of two variables is still relatively low.

This research is motivated by the low ability of students to understand basic concepts and students' interest in learning mathematics. The purpose of this study was to determine the improvement of student learning outcomes through the use of Problem-Based Learning in class X mathematics subjects. The research method used was qualitative and quantitative data analysis, with the research subjects of all 34 students of class X. Based on the processing and results of data analysis, the application of the Problem-Based Learning model in mathematics learning has increased after the actions of cycle I, II, and cycle III were held. Student learning outcomes in the first cycle have an average grade of 73.5%, student learning outcomes in the second cycle have slightly increased, namely the average grade of 81.4% and classical absorption of 73.5%, then proceed to the cycle III and experienced an even better improvement, with an average grade of 83.5% and classical absorption of 88.2%. The conclusion of this research is that learning mathematics using Problem-Based Learning can improve the learning outcomes of class X students at SMA Karya Pembangunan Cicalengka.

The purpose of this study was will explain students' mistake when working on math problem on the lesson of flat-sided geometry material at SMP Negeri 8 Cimahi Class VIII, namely 27 people. Used qualitative research with descriptive method. How to collect data, namely test instruments and interview with seven description question. The results of the student's response test for question number five were 29.63%, for question number seven it was 37.04%, and for question number three it was 40.74% still very low. Research conducted by students is difficult when working on these question. Explanation of data and assessment of students made part type of errors, is: (1) students' difficulties in understanding concept; (2) difficulty understanding question or not being careful when understanding question so that students' response are incomplete; (3) difficulty in understanding mathematics theory or the prerequisites of the Pythagorean theorem; (4) lack of accuracy when working on the calculation phase. This proves that class VIII students are very low when working on the problem of building a flat side room.
