The study aims to find out pseudo-thinking in solving mathematical problems. The methods used in this study are qualitative descriptive. The research subject is junior high school students using the purposive sampling technique, the students are grouped into three ranks i.e. low, medium and high rankings which each ranked 3 students as respondents. The total number of respondents was 9 students. Data collection techniques using tests, interviews, and documentation. From the results of the study gained that: 1) students who are ranked low in solving mathematical problems are experiencing pseudo-analytic or pseudo-false, 2) students who are in the moderate level also experience pseudo-analytic or pseudo-incorrect, 3) students who are in high ranking experience pseudo-analytic and pseudo-4) students who experience pseudo-thinking choose procedures using their own reasoning and convince it as a correct understanding , so there is no attempt to re-examine what he has done

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.

One factor in learning mathematics is the need for communication skills. Carpenter & Gorg (2000: 60) states "Communication is an essential part of mathematics and mathematics education", which means that communication is an important part of mathematics and mathematics education. Mathematical communication is related to problem solving, because with the existence of mathematical communication students will understand better in solving mathematical problems. This qualitative descriptive study aims to describe the written mathematics communication of junior high school students in solving mathematical problems in terms of students' mathematical abilities. The data obtained came from three subjects, namely VIII grade junior high school students who had received the material system of two-variable linear equations (SPLDV). The three subjects consisted of students with high mathematical abilities, students with moderate mathematical abilities, and students with low mathematical abilities. The results of this study are the accuracy of writing mathematics for high ability and medium ability students is declared accurate, but low abilities is not declared accurate. In the completeness aspect, high ability and medium ability students written mathematics communication is complete for any information that has been submitted. But, student with low abilities is not complete. In the aspect of fluency, students with high abilities are able to communicate fluently in mathematics, but students with moderate and low abilities cannot fluently. . Keywords: Mathematical Communication, Problem Solving, Mathematical Ability.

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
