Learning media in Mathematics by using Microsoft Excel software that assisted Visual Basic application is a tool that can be applied for a more interactive visualization so that students better understand about mathematical concepts. Microsoft Excel is a software that serves to process data in the form of numbers that are always associated with mathematical commands. In addition, the functions of commands in Microsoft Excel can be applied in various fields such as Statistics, Economics and Finance, Mathematical Logic, and Engineering. If using mathematical concepts with data processing. But it is not just a number, it can also be used to process objects on shapes or drawings on images. This, of course, requires a function other than the mathematical functions of Visual Basic Applications, which can make math tools more interesting. The advantages of Microsoft Excel with Visual Basic for Application (VBA) are (1) the images are more interactive with different sizes and can make more; (2) more economical; (3)saving time; (4)the software is easy to find, and (5)improving students 'understanding of mathematical concepts and foster students' sense of trust, especially in junior high school students.

Do textbook series in arithmetic develop the mathematical concepts and skills in accordance with current learning theory? This is an important question for the junior high school mathematics teacher. The answer determines the extent to which the teacher may rely on the textbook for guidance in the learning sequence. Since, for many students, mathematics instruction ceases at ninth grade, mathematical strands considered by teachers and textbook writers to be important must be brought to a culminating point by that time.

This research was motivated by several reasons: (1) there was a misconception of some elementary school geometry materials that were considered essential; (2) the form of evaluation given was dominantly objective/multiple choice; (3) teachers' teaching methods tend not to be contextual; and (4) students' way of thinking simply to take the practical one. Through this research, it is expected to obtain information about: geometrical reasoning in elementary schools according to Bruner's theory, problem solving and mathematical representations. Theresearch was conducted in a descriptive analytic form, with the following steps: (1) giving questions for the geometry reasoning test for SMP; (2) analyzing answers according to the criteria of reasoning; and (3) mapping students' answers to the results of the analysis according to the profile criteria. The data obtained were analyzed, and the results were described to illustrate the condition of the geometric reasoning abilities of elementary school students. Theresults obtained in this study were: (1) The Mastery of the concept of geometry in each junior high school/equivalent. The target with the acquisition of an average score from all schools was 55, which was quite low because there were some students who did not master the concept of geometry and there were other mathematical concepts related to solving test questions; (2) There was no significant difference in the mastery of geometry concepts for male or femalestudents for each SMP/equivalent target, except for one school, namely SMP Negeri 17, which was because males are superior to females in three questions with a difference in the percentage of numbers of significantly correct; (3) The mastery of geometry concepts in each junior high school. The target of studying each geometry material was considered good, except for question number 1 with the subject of the Pythagorean Theorem, because students were dominant in not being able to use the relationship between concepts, especially the operation ofthe compounding form and the roots.

The purpose of this study was to obtain an overview of the mathematical connections of junior high school students on the concepts of ratio and proportion. This research uses a descriptive qualitative method with data triangulation. The research participants were four junior high school students in Sukabumi. The instrument used in this study consisted of a description test of three questions that had been consulted with experts and based on considerations regarding indicators of mathematical connection ability. Based on the results of the study, it is known that the ability of students to recognize and use connections between mathematical ideas is 50%, the ability of students to connect and apply mathematical concepts with other disciplines is 50%, and the ability of students to connect and apply mathematical concepts to problems in everyday life with a percentage of 50%. The results showed that the mathematical connection ability of some junior high school students in Sukabumi on the concept of comparison was included in the poor category.

Pemahaman Konseptual Matematis (PKM)  memiliki peran penting karena dengan kemampuan ini siswa mudah dalam membangun hubungan untuk memahamai ide dan konsep baru. Kemampuan PKM ini dapat ditumbuh-kembangkan melalui pembelajaran di kelas. Untuk mencapai kecakapan tersebut, pembelajaran perlu memperhatikan keberagaman siswa karena pembelajaran yang mengakomodasi keberagaman menjadi lebih efektif, efesien, dan menarik. Keberagam tersebut dapat berupa Gender (G), Kemampuan Awal Matematika (KAM) dan Gaya Belajar Matematis (GBM) siswa. Salah satu pendekatan pembelajaran yang mengakomodir keberagaman ialah pembelajaran pendekatan Rigorous Mathematical Thinking (RMT). Artikel ini bertujuan untuk mengkaji kemampuan PKM siswa SMP yang memperoleh pembelajaran pendekatan RMT ditinjau dari : a). Gender, b). KAM siswa, dan c). GBM siswa. Penelitian ini merupakan penelitian eksperimen pada siswa SMP di salah satu sekolah di Bandung. Salah satu hasil yang penting adalah dengan pembelajaran ini menjadikan siswa dengan KAM sedang dan rendah dapat mencapai kemampuan yang baik. The Effect of Rigorous Mathematical Thinking (RMT) Learning Approach On Students’ Understanding of Mathematical Concepts AbstractAn understanding of mathematical concepts (PKM) has an important role because with this ability students are easy in building relationships to understand new ideas and concepts. The ability of PKM can be grown-developed through learning in the classroom. To achieve these skills, learning needs to pay attention to the diversity of students because learning that accommodates diversity becomes more effective, efficient, and engaging. Such diversity can be Gender (G), An initial mathematical ability (KAM) and students’ mathematics learning styles (GBM). One approach to learning that accommodates diversity is the Rigorous Mathematical Thinking (RMT) learning approach. This article aims to examine the ability of junior high school students who have learned RMT approach in terms of: a). Gender, b). students’ KAM, and c). students’ GBM. This research is an experimental research on junior high school students in one school in Bandung. One important result is that this learning engages students with medium and low of KAM able to achieve good abilities.

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.

There has never been a more interesting time to be teaching mathematics. The new programs are rich in subject matter and are a challenge to students and teachers a like. We are building mathematical concepts in addition to drilling on fundamentals in the same amount of time which previously had been used for drilling alone. This presents a substantial problem to which, I am sorry to say, I do not have the total solution. My concern is with being able to teach all of the mathematics desired in the time that is available. There is one device of instruction in the new materials that I believe has great potential in conveying mathematical ideas quickly and accurately. This device is the number line.
