<![CDATA[ABSTRACTThe purpose of this study was determine the application of contextual teaching learning approach to improve the mastery of concepts volume of the rotary object. The study design was nonequivalent pretest-posttest control group design. Data collection technique used pretest and posttest to determine the mastery of concepts of volume of the rotary object. Hypothesis testing using t-test to compare the the mastery of concepts volume of the rotary object in the experimental class and control class, then a further test by comparing the mean (compare means) and average absolute gain Based on the research result the data show that it can be concluded that the approach of contextual learning significantly distinction of concepts volume of the rotary object. Keywords: Contextual Teaching Learning Approach, The Mastery of Concepts, Volume of The Rotary Object]]>

<![CDATA[Mathematics is a science that is structured and consists of integrated concepts. So in solving problems in mathematics, good mathematical connection skills are needed. The purpose of this study was to analyze and describe the mathematical connection abilities of high school students in the Arithmetic Sequences and Series material. This type of research used is a qualitative descriptive study with the research subjects being students of class XI in a high school in Bekasi Regency with a total of 30 students. Data collection techniques used in this study were interviews and tests, while the data analysis technique consisted of 3 stages, namely data reduction, data display and then a conclusion was drawn from the research results. From the results of the study, it is known that the mathematical connection ability of students on the connection indicator between mathematics and everyday life is obtained by a percentage of 70% which is in the medium category, on the indicator of the connection between concepts in one mathematics material and the inter-topic connection in mathematics obtained a percentage of 73% and has entered the high category, then the last indicator, namely the connection between mathematical material, namely arithmetic sequences and arithmetic series with other sciences, gets the highest percentage of other indicators, namely 84% and is in the high category. Overall the average mathematical connection ability of the students was in the high category.]]>

<![CDATA[Mathematical problem solving skills are one of the important skills that students have in learning mathematics. The purpose of this study is to describe students' mathematical problem-solving ability to solve PISA problems on quantity content. This research uses qualitative methods. The subjects in the study were students of class IX A SMPN 2 Tirtamulya. The data collection technique in this study is to provide a test in the form of two PISA Math problems. The results of this study are the average score of mathematical problem-solving skills of students classified into the medium category, which is 10.33. Students' mathematical problem-solving abilities in high categories meet the entire stage of problem solving, namely understanding problems, devising a plan, carrying out the plan, and looking back. The mathematical problem-solving ability of students in medium category is fulfilling the stage of devising a plan and carrying out the plan. Students' mathematical problem-solving abilities in low categories meet one of four stages, namely devising a plan.]]>

<![CDATA[This program is one of the community service programs carried out by groups of lecturers and student representatives of the mathematics education program at UNSIKA. This program is in the form of providing tutoring outside school hours to elementary school students in mathematics. Most students are of the view that mathematics is difficult. Based on these conditions, we will design a program to help the school in providing tutoring to students in dealing with students to facilitate learning multiplication and division. The form of the program is in the form of providing tutoring for elementary school students, to facilitate student learning in completing multiplication and division operations. For the implementation of this activity, the mathematics textbooks and modules that are designed for guidance and study must be prepared. The material to be applied is about mathematical materials that have been summarized relating to multiplication and division operations. The structure of teaching materials for each topic starts with concepts, examples of questions, exercises, discussions and key answers. The textbook is ready to be used for the program.]]>
