<p class="Abstrak"><strong>Abstract:</strong> The purpose of this study is to describe the algebraic reasoning of junior high school students in solving mathematical problems in terms of Adversity Quetients. The study was conducted in Tarus Self-help Junior High School. The stages of students’ algebraic reasoning in solving problems were generalisation activities, transformation activities, and global metal-level activities. The instruments used in this study were ARP instruments (Adversity Response Profile), algebraic reasoning tests, and interview guidelines. The results of this study showed that the Climber students did algebraic reasoning on generalisation activities, transformation activities, and global metal-level activity. The Camper students only did algebraic reasoning on general activities. While Quitter students did not do algebraic reasoning on all activities.</p><strong>Abstrak:</strong> Tujuan penelitian ini mendeskripsikan penalaran aljabaris siswa SMP dalam memecahkan masalah matematika ditinjau dari <em>Adversity Quotient. </em>Penelitian dilakukan di SMP Swadaya Tarus Kupang.

Visual Basic Application for Excel is a simple program language and has the power to process data quickly, let alone the utilization of math functions in Microsoft Excel can help work on Excel display more interactive so that teachers can create props inside Excel. The advantages of Microsoft Excel compared to mathematical software are the many math functions and images available in the form of shapes or pictures. With the availability of VBA, math and image functions in Microsoft Excel, teachers can design the creation of media related to mathematics learning especially helping to develop the ability of junior high school students who have difficulty connecting mathematics lessons with basic mathematics knowledge requirements. In general, that most students in Indonesia have not solved mathematical problems, therefore, by using VBA for Excel the ability of junior high school students to improve in the usual way significantly with a t-test with 0.006 <0.05 and there is an association between Trust self-comfidence student with students' mathematical comprehension skills with a contingency value with a significant amount of 0.016 <0.05 with a contingency coefficient of 0.525 including a moderate association

Mathematical Connection

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 purpose of this study is to describe the intuition characteristics of junior high school students in solving mathematical problems viewed from mathematical abilities. This research based on qualitative descriptive study. The subjects of this study were taken from Lab School UNESA  Junior High School, which consisted of three students from class VIII A, namely one student with high, moderate,  and low mathematical ability. The method that used to collect data consists of the mathematical ability test,  problem solving test and so of the interview method. Data analysis uses the intuitive characteristic indicators at each stage of the problem solving. The conclusion of this study indicate that student with high mathematical ability at the stage of understanding the problem using affirmatory intuition with the characteristics of extrapolativeness, intrinsic certainty and perseverance, at the stage of making plans using anticipatory intuition with the characteristics of global ideas, and at the stage of carrying out plans and checking again not using intuition. Student with moderate mathematical ability at the stage of understanding the problem using affirmatory intuition with the characteristics of extrapolativeness, intrinsic certainty and perseverance, at the stage of making plans using anticipatory intuition with the characteristics of global ideas, and at the stage of carrying out plans and checking again not using intuition. Student with low mathematical ability at the stage of understanding the problem using affirmatory intuition with the characteristics of perseverance and coerciveness, at the stage of making plans using anticipatory intuition with the characteristics of global ideas, and at the stage of carrying out plans and checking again not using intuition. Keywords: Intuition, Problem solving , Mathematics ability

This study aims to determine the profile of students' thinking in solving mathematical problems and to find out the results of the application of Brunerd's theory in solving the problem of building a Limas room in junior high school students.Retrieval Techniques The subjects in this study were seen from the results of tests with high, medium, low categories. High categories were seen from the test results if the answers to the tests were all correct, the categories were seen from the test results if the answers to the tests still had errors, while the categories were low seen from the test results if the answer to the test is still wrong. This technique is used because researchers have a specific purpose for several considerations, namely to find out whether the application of bruner theory can be applied in mathematics subjects, considering that mathematics is considered a difficult subject for students. The subjects of this study were 6 students. Data collection techniques in this study used test, interview and documentation methods while the data validity techniques in this study used triangulation techniques which included 3 elements, namely sources, methods, theories. In this study researchers used data analysis techniques with 3 components, namely: data reduction, data presentation, conclusion drawing.The results showed that subjects with a high category tended to have high-thinking profiles, they had no difficulty in doing tests and interviews. The subjects with the medium category were more likely to have thinking profiles, while they had a little difficulty in doing tests and interviews, while the subjects with the lower category were more likely to have low-thinking profiles, they had difficulty doing tests and interviews. This is what causes a difference between them. Based on the discussion, it can be concluded that junior high school students in their profile think in solving problems in the building of a limiter junior high school students are able to describe the building of Limas space means that SMP students are able to understand pyramid material shown to the sensitivity of students in learning to build Limas space so that junior high school students in their imagination are able to mention 1 example of a pyramid building and all junior high school students are able to mention the types of Limas indicated by the independence of junior high school students who are able to mention various types of building> 1 in terms of bases, and junior high students are able to say> 1 element the building elements of the Limas space means that junior high school students are able to understand the pyramid material shown to the sensitivity of junior high school students to be able to mention the Limas parts properly and correctly.
