Penelitian ini bertujuan untuk mendeskripsikan letak, jenis, faktor-faktor kesulitan, dan self-efficacy siswa SMP swasta di Kabupaten Sleman, DIY dalam memecahkan masalah matematika berbentuk soal cerita. Penelitian ini termasuk penelitian survei dengan pendekatan kuantitatif dan kualitatif. Subjek penelitian adalah 124 siswa SMP swasta di Kabupaten Sleman, DIY yang berasal dari empat sekolah dengan kategori tinggi, sedang, dan rendah. Sampel penelitian ditentukan dengan stratified proportional random sampling technique. Instrumen yang digunakan berupa tes diagnostik terdiri atas 5 butir soal, angket self-efficacy, dan pedoman wawancara. Hasil penelitian menunjukkan bahwa kesulitan siswa dalam pemecahan masalah matematika berbentuk soal cerita terletak pada pengetahuan faktual, pengetahuan konseptual, pengetahuan prosedural, dan pengetahuan metakognitif. Jenis kesulitan yang dialami siswa yaitu pada mengingat fakta, mengingat konsep, memahami fakta, memahami konsep, menerapkan konsep, menerapkan prosedur, menganalisis prosedur, mengevaluasi faktual, mengevaluasi konsep, mengevaluasi prosedur, dan mengomunikasikan metakognitif. Faktor-faktor kesulitan yang dialami siswa SMP dalam memecahkan masalah matematika berbentuk soal cerita kelas VIII yaitu siswa merasa waktu yang diberikan tidak cukup, mudah menyerah, kurang teliti, sering lupa, merasa cemas, dan siswa tergesa-gesa untuk mengerjakan soal. Self-efficacy dari 124 siswa berada dalam kategori tinggi dengan rata-rata sebesar 90,4.Kata Kunci: analisis kesulitan siswa, self-efficacy, pemecahan masalah matematika, soal cerita AN ANALYSIS OF DIFFICULTIES AND SELF-EFFICACY OF JUNIOR HIGH SCHOOL STUDENTS IN SOLVING STORY FORM MATHEMATICAL PROBLEMS AbstractThis research aimed to describe the positions, types, difficulty factors, and self-efficacy of junior high school students in Sleman, DIY in solving story form mathematical problems. This study was survey research using the quantitative and kualitative approach. The subjects of this research were 124 students of private junior high schools in Sleman, DIY, which were from four different school groups in the high, middle, and low categories. The sample was established using the stratified proportional random sampling technique. The instruments which were used namely diagnostic test that consisted of 5 items, self-efficacy questionnaire, and interview guides. The results indicate that students’ difficulties in solving story form mathematical problems lie on factual knowledge, conceptual knowledge, procedural knowledge, and metacognitive knowledge. The types of difficulties experienced by students include remembering fact, remembering concept, understanding facts, understanding concept, applying concept, applying procedure, analyzing procedure, evaluating fact, evaluating concept, evaluating procedure, and communicating metacognitive. Difficulty factors that grade VIII students experience in solving story form mathematical problems include: students feel that the time given is not enough, easily give up, are not meticulous enough, oftenly forget, and are anxious and impatient while solving the problems. The self-efficacy of 124 students can be categorized as high with an average score of 90.4.Keywords: analysis of students’ difficulties, self-efficacy, mathematics problem solving, story problem.

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

Difficult Subject

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.
