This study aims to explore and describe the process of problem solving geometry reach the level of visualization, analysis and informal deduction based on the Van Hiele theory. This type of research is descriptive explorative and qualitative approach. Subject of the study was obtained from the high school students who were tested on the level of Van Hiele geometry. Each level of visualization, analysis and informal deduction taken two learners who can communicate well. The results of this study indicate that solving problems in geometry learners who attained think visualization is to identify problems and set goals using the language question. Troubleshooting on the geometry of learners who attained think theanalysis is through fifth troubleshooting step IDEAL using their own language, but less systematic. Troubleshooting on the geometry of students who reach a level of thinking is through the informal deduction fifth troubleshooting step IDEAL by systematically using their own language.

Penelitian ini bertujuan untuk mendeskripsikan letak kesulitan siswa yang dominan dan faktor-faktor kesulitan yang dialami siswa SMA dalam memecahkan masalah matematika. Penelitian ini termasuk penelitian deskriptif dengan pendekatan kuantitatif dan kualitatif. Subjek penelitian ini adalah 94 siswa SMA Negeri di Kota Yogyakarta yang berasal dari tiga sekolah dengan kategori tinggi, sedang, dan rendah. Pemilihan subjek penelitian dilakukan dengan stratified proportional random sampling. Pengumpulan data dilakukan dengan menggunakan dokumen, tes, dan wawancara. Analisis data dilakukan dengan metode analisis deskriptif kualitatif dengan pendekatan kuantitatif dan kualitatif yang memberikan gambaran mengenai letak dan faktor kesulitan siswa. Hasil penelitian menunjukkan bahwa kesulitan matematika siswa terletak pada kesulitan mengingat fakta 1,77%, kesulitan memahami fakta 3,54%, kesulitan menerapkan fakta 3,54%, kesulitan menganalisis fakta 10,18%, kesulitan mengingat konsep 1,33%, kesulitan memahami konsep 13,27%, kesulitan menerap-kan konsep 11,95%, kesulitan menganalisis konsep 4,42%, kesulitan memahami prosedur 7,52%, kesulitan menerapkan prosedur 15,49%, kesulitan menganalisis prosedur 16,37%, kesulitan mengingat konsep visual-spasial 1,33%, kesulitan memahami visual-spasial 3,54%, kesulitan menerapakan visual-spasial 3,10%, dan kesulitan menganalisis visual-spasial 2,65%. Faktor-faktor kesulitan yang dialami siswa SMA dalam memecahkan masalah matematika kelas XII program IPA yakni: siswa kurang teliti, tergesa-gesa dalam mengerjakan soal, lupa, kurang waktu untuk mengerjakan soal, cepat menyerah, terkecoh, dan cemas. Kata Kunci: analisis kesulitan, pemecahan masalah matematika, kemampuan pemecahan masalah   AN ANALYSIS OF SENIOR HIGH SCHOOL STUDENTS’ DIFFICULTIES IN MATHEMATICS PROBLEM SOLVING BASED AT GRADE XII OF SCIENCE PROGRAM IN YOGYAKARTA CITY Abstract This research aims to describe the locations of the difficulties and the factors of the difficulties faced by Senior High School students in mathematics problem solving in Yogyakarta City. This research is descriptive supported by the quantitative and qualitative approach. The subject of this research was 94 grade XII students of senior high schools in Yogyakarta City. The sample was established from three different schools grouped in the three categories namely high, middle, and low category. The subjects of this research were selected by using the stratified proportional random sampling. The data were collected from the documents and the result of the test and interviews. The data analysis was done by using the qualitative descriptive analysis method with quantitative and qualitative approach that figure out the types and factors of students’ difficulties. The research result suggests that mathematics difficulty locations faced by the research subjects are fact remembering difficulty 3.54%, fact analyzing difficulty 10.18%, concept remembering difficulty 1.33%, concept understanding difficulty 13.27%, concept applying difficulty 11.95%, concept analyzing difficulty 4.42%, procedure understanding difficulty 7.52%, procedure applying difficulty 15.49%, procedure analyzing difficulty 16.37%, visual-spasial concept remembering difficulty 1.33%, visual-spasial understanding difficulty 3.54%, visual-spasial applying difficulty 3.10%, dan visual-spasial analyzing difficulty 2.65%. The factor that make the student difficult in mathematics problem solving was external factor, which is: student that carelessness, answering the question in a hurry, forgetfullness, and having a time limit in doing the work, easily giving up, getting decieved, and being worried. Keywords: analysis of difficulties, mathematics problem solving, problem solving skill

Geometry is among the cornerstones of mathematics because of its applicability in real life and its connection to other areas of mathematics. The reported study explored how the volume of 3D geometric shapes was taught in one high school in Lesotho. One male teacher and an intact class of sixty high school students were the participants of the study. The study was exploratory in nature. This was in order to understand the phenomenon under study so as to suggest ways on how to make some improvements for the future. Data were collected through classroom observations, photo shootings, note-taking, and interviews. Classroom observations enabled the researchers to start the analysis while also observing. The photos taken captured the nature of the tasks given to students, some explanations, and class interactions. The Van Hiele theory of geometric thought was used as the framework of analysis. The findings of the study show that at level 1, the teacher focused mainly on the vocabulary of the concept at hand, the information phase. Another phase which was dominant in the teaching at the same level is the direct orientation. The free-orientation phase was not fully realized. The analysis level was achieved through the information phase and the direct orientation phase. Thus the progression from one level to another by students occurred having some phases of learning being skipped due to the way the instruction was organized. It is postulated that lack of proper understanding of some concepts in geometry by students may result from this kind of instruction.

Achievement In Mathematics

The major aim of teaching Mathematics is to develop problem solving skill among the students. This article aims to find out the problem solving strategies and to test the students’ ability in using these strategies to solve problems. Using sample survey method, four hundred students were taken for this investigation. Students’ achievement in solving problems was tested for their Identification and Application of Problem Solving Strategies as a major finding, thirty one percent of the students’ achievement in mathematics is contributed by Identification and Application of Problem Solving Strategies.
