Desain Pembelajaran Matematika Bagi Calon Guru Matematika (Mathematics Learning Design for Pre‐Service Mathematics Teacher)

Pembelajaran matematika bagi calon guru matematika melibatkan sedikitnya tiga aspek proses, yaitu; konstruksi, refleksi dan komunikasi. Konstruksi bertujuan agar calon guru "mengalami" belajar. refleksi bertujuan untuk menginternalisasi pengetahuan yang telah dikonstruk dan komunikasi bertujuan agar pengetahuan itu menjadi informasi yang bermakna. Makalah ini membahas hasil ujicoba desain pembelajaran yang berorientasi kepada membangun ketiga aspek kemampuan itu

Developing Mathematics Teaching Material “Investigative” for Pre-Service Mathematics Teacher

Teaching material are significant component for supporting teaching-learning activities. Based on the teaching material, goal and the kinds of learning activities are determined. Also, the interaction among learning components are determined by teaching material design. Therefore, teaching material have central role that ascertain learning activities. Unfortunately, current teaching material not continually suitable with the newest situation or real class situation. Therefore it is needed continous effort to develop so that it is able to overcome the dynamic learning situation. Based on the reason this reseach focus on developing teaching material that is able to facilitate the learner are able to do investigation, and in this article named as Investigative Teaching Material. Try out result recommend that, activities structure of investigation must be “strong structured” and “strong organized”. The detail of the activities are as follow: (information display, (2) preliminaries activities from real situation, (3) investigation activities in semi abstract level, (4) generalization, and (5) internalization.

Efforts to Build Students' Mathematical Problem-solving Ability Through Problem-based Learning Models on Number Operation Materials in Class VII SMPN 25 Malang

The background of this research is students’ low mathematical problem-solving ability. The purpose of this study was to determine the efforts to build mathematical problem-solving abilities of junior high school students, especially in the number operations material caused by the lack of attention and involvement of students in the learning process, students’ difficulties in understanding story problems related to contextual problems, and students who were less active and creative. in constructing problem-solving ideas. Therefore, we need a learning model that can build students’ mathematical problem-solving skills, namely the problem-based learning model. This research was conducted at SMPN 25 Malang as classroom action research (CAR) which refers to the MC Taggart learning model which was carried out for two cycles. The study was carried out on 31 students of class VII.C. The results of this study indicate that the test results of students’ mathematical problem-solving abilities have changed for the better from cycle I to cycle II, where in cycle II the average score has reached 76 and the criteria for completeness have exceeded the mastery limit, which is 87.10%. In this case, it can be concluded that the application of the problem-based learning model can build the mathematical solving abilities of students in class VII-C of SMPN 25 Malang.

Penalaran Imitatif Siswa Berkemampuan Matematika Tinggi dalam Memahami Sistem Persamaan Linear Dua Variabel

Penelitian ini bertujuan untuk mendeskripsikan penalaran imitatif siswa SMP dalam memahami sistem persamaan linear dua variabel. Jenis penelitian ini merupakan penelitian deskriptif dengan pendekatan kualitatif. Penelitian ini dilaksanakan pada siswa kelas VIII E SMPN 7 Pasuruan tahun ajaran 2022/2023. Dua subjek dalam penelitian ini dipilih dengan kriteria jawaban tes tuntas dan benar dengan menunjukkan adanya tiruan prosedur, menggunakan metode SPLDV yang sama, serta mempertimbangkan kemampuan siswa mengomunikasikan pemikirannya saat proses wawancara dan keteraturan penyusunan jawaban pada lembar pekerjaan tes. Hasil penelitian menunjukkan bahwa pada unsur berlandasan matematika, subjek mengerti susunan langkah-langkah dalam menyelesaikan soal, tetapi dalam menerapkannya subjek hanya fokus untuk mengecek proses perhitungannya saja tanpa memperhatikan kelogisan dari langkah pemisalan variabel dan kesimpulan yang dibuat. Pada unsur peniruan prosedur, subjek menyelesaikan soal dengan mencontoh prosedur penyelesaian soal rutin SPLDV dan berkeyakinan bahwa prosedur tersebut hanya dapat diterapkan dengan mengikuti aturan pengerjaan yang telah dijelaskan oleh guru. Sedangkan pada unsur argumentasi logis, kedua subjek memiliki kemampuan yang berbeda dalam memberikan alasan logis dari prosedur penyelesaian yang telah dilakukan. Namun dalam hal membuktikan kebenaran kesimpulan, kedua subjek sama-sama tidak dapat menghubungkan jawaban pada pertanyaan sebelumnya untuk menjelaskan bukti terkait rincian uang untuk membeli bahan kue bipang yang dibutuhkan jika diketahui jumlah uang yang dikeluarkan

Profil Pemecahan Masalah Siswa Berdasarkan Tahapan Polya Ditinjau dari Kecerdasan Emosional

Pemecahan masalah merupakan hal yang sangat penting dalam proses pembelajaran matematika dikarenakan ketika siswa memiliki kemampuan pemecahan masalah yang baik maka akan mampu mentransfer kemampuan pemecahan masalahnya dalam memecahkan masalah kehidupan sehari-hari. Oleh karena itu tujuan penelitian ini adalah mendeskripsikan proses pemecahan masalah siswa berdasarkan tahapan Polya ditinjau dari kecerdasan emosional. Penelitian ini merupakan penelitian kualitatif dengan jenis deskriptif. Pemilihan subjek dilakukan secara purposive sampling dengan diikuti oleh 58 siswa di SMPN 1 Tajinan yakni 32 siswa dari kelas XI A dan 29 siswa dari XI B. Subjek dalam penelitian ini yaitu tiga siswa yang terdiri dari satu siswa kecerdasan emosional tinggi, satu siswa kecerdasan emosional sedang dan satu siswa kecerdasan emosional rendah.

Teacher interventions to induce students’ awareness in controlling their intuition

This study aimed to describe teacher interventions in students’ problem-solving. The subjects were three upper- class students at an elementary school in Indonesia who used system 2 when solving problems. This study used a qualitative case study approach. Data were obtained from students’ written answers and audio-visual recordings of teacher interventions to students. The results showed that the subjects needed teacher interventions to induce their awareness when involving system 2. Each subject needed intervention different stages. Subject 1 required intervention stage 3, subject 2 required intervention stage 2, and subject 3 only required intervention at stage 1. From the research results, it was known that the active moment of system 2 in all three subjects was the same, that is after the core problem was known. The core of the problem was ascertained after a doubtful feeling arose on the truth of the resulting answers. This feeling arose because the teacher intervened in the form of questions conducted dialogically

PROFIL FOLDING BACK SISWA DALAM MENYELESAIKAN SOAL CERITA

The purpose of this study was to analyze and describe student folding backs in solving linear program problems based on Polya's steps. This research use desciptive qualitative approach. The subjects of this study consisted of 3 subjects, namely S1, S2, and S3 indicated that they were doing folding back. The results of this study indicate that the S1 folding back occurs. S1 is a subject who has problems when defining variables but already knows the steps to work well. Folding back is done by S1 in defining variables. Folding back is also carried out by S1 to determine the point of intersection between two lines. The intercept obtained by S1 is algebraically and geometrically different. S2 is a subject that has not been able to plan completion. Folding back is carried out by S1 in defining variables and formulating constraints. S2 writes constraints in two forms, namely equations and inequalities. Folding back is also carried out by S2 in determining the coordinates of the intersection point, drawing a graphic sketch of the inequality, determining the coordinates of the extreme points, and determining the optimum value. S3 is a subject that has been able to carry out the plan but has less accuracy. This folding back is done by S3 in writing the coordinates of a point, determining the point of intersection between two lines (because it is not careful in calculations), and when drawing inequality graphs (because it does not draw a complete graphic sketch).Keywords: folding back, proble
