Abstract: Purpose of this research was to study students' pseudo thinking in concept of fractions. Data obtained using questions and interviews. Question used to find answers of students in understanding concept of fractions. Interviews used to find reasons for students answer. Findings show that students think pseudo conceptual, true-pseudo and false-pseudo. Pseudo conceptual thinking when students condition not understand shade when drawing fractions. Thinking true-pseudo when students in state not understand concept of drawing fractions begins with same size and broken down as much denominator fractions. Thinking false-pseudo when students state poor understanding problem and reflection for concept of drawing fractions.Abstrak: Tujuan penelitian ialah untuk mempelajari berpikir pseudo siswa dalam konsep pecahan. Data diperoleh dengan menggunakan instrumen soal dan wawancara. Soal digunakan untuk mengetahui jawaban siswa dalam memahami konsep pecahan. Wawancara digunakan untuk mengetahui alasan siswa dalam menjawab. Temuan menunjukkan bahwa siswa mengalami berpikir pseudo conceptual, true-pseudo dan false-pseudo. Berpikir pseudo conceptual saat siswa pada kondisi tidak memahami perlunya mengarsir saat menggambar pecahan. Berpikir true-pseudo saat siswa pada kondisi tidak memahami konsep menggambar pecahan berawal dari ukuran yang sama dan dipecah sebanyak penyebut pecahan. Berpikir false-pseudo saat siswa pada kondisi kurang memahami soal dan diperlukan refleksi konsep menggambar pecahan.

Abstract: This study used a qualitative-descriptive study with the aim of this study to describe the pointing profile and gesture representation of students in solving mathematical problems with the material of linear functions. The subjects in the study were 2 students of class X SMA Negeri 2 Dompu. The research subjects were selected by 1 student as the pointing gesture and 1 student as the representational gesture. Data was collected by providing assignments, gesture observation sheets, and interviews with selected subjects. The data were analyzed qualitatively through data reduction, data presentation, and drawing conclusions. This study resulted that the pointing gesture helped P1 describe the answer completion plan, helped focus himself to perform calculations, generate ideas, and facilitate the description of information from questions and answers as well as check and understand questions and answers when solving questions. Representational gesture helps R1 to describe the steps to understand the graphic related to the problem, helps focus on understanding the problem and can be careful in solving the problem. Also plays a role in concretizing ideas/ideas that are being worked on or are being thought of by students.Abstrak: Penelitian ini menggunakan penelitian kualitatif-deskriptif dengan tujuan penelitian ini untuk mendeskripsikan profil pointing dan representasi gesture siswa dalam menyelesaikan soal matematika materi fungsi linear. subjek dalam penelitian adalah 2 orang siswa kelas X SMA Negeri 2 Dompu. Subjek penelitian dipilih 1 orang siswa sebagai pointing gesture dan 1 orang siswa sebagai representational gesture. Perolehan data dilakukan dengan memberikan lembar tugas, lembar Observasi gesture, dan wawancara yang terpilih menjadi subjek. Data di analisis secara kualitatif melalui reduksi data, penyajian data, dan menarik kesimpulan. Penelitian ini menghasilkan bahwa Pointing gesture membantu P1 menggambarkan rencana penyelesaian jawaban, membantu memfokuskan dirinya untuk melakukan hitungan, memunculkan ide, dan mempermudah gambaran informasi dari soal dan jawaban serta mengecek dan memahami soal dan jawaban saat menyelesaikan soal. Representational gesture membantu R1 untuk menggambarkan langkah memahami grafik terkait hubungan dengan soal, membantu memusatkan perhatian memahami soal dan dapat teliti dalam menyelesaikan soal. Berperan juga untuk mengkongkretkan ide/gagasan yang sedang dikerjakan maupun sedang dipikirkan siswa.

This study aims to reveal mathematical connections of elementary school teachers in solving trigonometric problem. The subjects of this study were 22 elementary school teachers as the prospective participants of Professional Teacher Education and Training (PTET). They came from several districts of South Sulawesi Province. The teachers were given trigonometry problem. Trigonometry problems could encourage teachers to connect geometrical and algebraic concept, graphical representation and algebraic representation, as well as daily life context. The result shows that most of the subject teachers of this study solved the problem according to procedures they know without considering everyday life context. On the other hand, there were some subjects who connected problem with everyday life context using graphical, verbal, or numerical representation. Thus, subjects who were able to connect problem information with appropriate concepts and procedures are categorized as substantive connections. While the subjects who were able to connect problem information with mathematical concepts but less precise in using the procedure are categorized as classification connections.

The problem that arises in learning the material for sequences and series in class XI Accounting at An-Nuuru Tirtoyudo Islamic Vocational School is the low problem-solving ability. These indications are seen, among others, the lack of basic knowledge of students about mathematics, counting errors, errors in applying strategies, inability to translate problems in mathematical form, misinterpreting problems in mathematical concepts, and lack of understanding of problems that arise. The application of the Problem Based Learning (PBL) model is an alternative that can be done by teachers to improve mathematical problem solving abilities. This research is a Classroom Action Research (CAR) on the Implementation of Problem Based Learning (PBL) Models to Improve Problem Solving Ability of Class XI Accounting Students at SMK Islam An-Nuuru Tirtoyudo. The results showed that the application of the PBL model could improve mathematical problem solving abilities. The stage of orienting students to problems, among others, students can relate the problem to the knowledge they have, can determine the things that are known, and can determine the things that are asked. The stage of coordinating students to learn through the formation of study groups. The stage of guiding the investigation is done by going around each group to provide facilities to students who have difficulty. The stage of developing and presenting the work is done by asking students to present their work in the form of reports, photos, videos, and others. The stage of analyzing and evaluating problem solving is done by asking students to re-examine the process and problem solving results obtained.

PSEUDO SISWA DALAM MENYELESAIKAN SOAL BERTIPE HIGHER ORDER THINKING SKILLS BERDASARKAN AKTIVITAS PROBLEM SOLVING Dwi Susanti; Purwanto Purwanto; Erry Hidayanto

Learning mathematics involves students not only to be able to ensure calculations but also be able to ensure reasoning and analyzing. Analytical skills are included in high order thinking skills (HOTS). Higher order thinking skills (HOTS) can be generated through problem solving activities. In solving a problems, it is possible that the way the student thinks is not suitable to the answer they get or it can be said that they are doing pseudo thinking. Pseudo thinking can be caused by the absence of reflection by students. This study aims to describe the student's occurring false-pseudo thinking in solving HOTS type problems on the quadratic inequality. Research subjects were taken based on purposive sampling, taking into account their communication abilities. The subjects in this study were high school students who had studied the material inequality squared. The data collection was done by using think-out-loud (TOL) method, the students were asked to express out loud what they were thinking when solving the problem which was given. From the results it can be explained that the process of the students’ false-pseudo thinking HOTS type problems on the quadratic inequality happen as follows: 1) It begins with the students’ mistake of making assumptions when they are understanding the problem 2) The incompleteness of the students’ thinking substructure in the process of understanding the problem, and 3) The incompleteness of the students’ thinking substructure in planning the solution.
