Teachers’ diagnostic practice on students-difficulties is one of the important steps in designing and managing classroom lessons. The purpose of this study was to explore teachers’ perception and practices regarding diagnosing students’ learning difficulties. The participants of the study were 28 Indonesian mathematics teachers of Junior High School. The data was collected through a Focus Group Discussion and a teacher questionnaire. The data were analyzed qualitatively to describe how the teachers perceive learning difficulties and how the teachers diagnosed students’ learning difficulties. The results of the analysis reveal that the teachers do not yet perform an in-depth diagnosis of students’ difficulties in learning mathematics. The teachers only focus on the mathematics topics and non-mathematical issues, instead of on students’ thinking process. The teachers also do not differentiate the diagnosis, evaluation, and prediction test. With regard to the strategies used by the teachers to diagnose students’ difficulties, analyzing students’ responses to tests was the majority. In this respect, observing students’ learning process during classroom activities is rarely done by the teachers in the purpose of diagnosing students’ learning difficulties. The results of the diagnosis are mainly used as the basis for remedial and drill and practices. The results imply that more support is needed for teachers to improve their competences particularly in diagnosing students’ thinking process difficulties when learning mathematics.

This quasi-experimental study aims to determine the impact of realistic mathematics education (RME) on increasing Mathematical Problem-Solving Abilities (MPSA). The research design used was the non-equivalent control group with the subject population of all junior high school students in the city of Yogyakarta originating from low (C), moderate (B), and high (A) levels. From each school level, one school was taken then from each school taken an experimental class that received RME and one class of control who received regular learning (PB). The instrument used is in the form of two sets of equivalent MPSA tests. Data analysis uses the t-test and Anava. The results of the research were: (1) an increase in the MPSA of RME students was higher than the increase in the MPSA of PB students for all students and all levels of the school; (2) the highest increase in MPSA for RME students occurs at level A schools; and (3) there is no interaction between learning at school level in increasing MPSA.

Tujuan penelitian ini adalah untuk mengetahui perkembangan belajar operasi pecahan siswa sekolah dasar menurut teori Gravemeijer di Kabupaten Ngada NTT. Jenis penelitian kualitatif fenomenologi digunakan untuk mencapai tujuan penelitian. Dalam penelitian ini Hypothetical Learning Trajectory (HLT) memainkan peranan penting sebagai instrumen penelitian. Perangkat pembelajaran yang disusun untuk menjalankan serangkaian aktivitas belajar dalam HLT telah dikonsultasikan dengan dua orang ahli Pembelajaran Matematika selanjutnya diuji coba pada kelompok kecil yaitu lima siswa Kelas IV Sekolah Dasar Katolik Bomari Langa pada tahap eksperimen pilot. Selanjutnya HLT dibandingkan dalam proses pembelajaran sebenarnya pada tahap eksperimen pengajaran dengan 24 siswa. Berdasarkan analisis ditemukan bahwa siswa dapat berkembang dalam belajar operasi pecahan dengan menggunakan tingkat aktivitas yang berbeda berdasarkan pendekatan PMR menurut teori Gravemeijer. Pada level pertama yaitu level situasional, Drama Matematika dapat menstimulasi pengetahuan informal siswa tentang prosedur operasi penjumlahan dan pengurangan pecahan. Pada level referensial, untaian manik-manik dan kartu pecahan menjadi model dari situasi drama matematika yang merupakan jembatan menuju gagasan penggunaan garis bilangan untuk operasi penjumlahan dan pengurangan pecahan. Pada level ketiga yaitu level general, siswa dapat menggunakan garis bilangan sebagai model untuk operasi penjumlahan dan pengurangan pecahan. Pada level formal, dengan bantuan untaian bilangan membawa siswa mengkonstruksi soal cerita sendiri dan menyelesaikan soal cerita yang dihasilkan dengan prosedur formal operasi penjumlahan dan pengurangan pecahan. Kata Kunci: Teori Gravemeijer, hipotesis trayektori belajar, penjumlahan dan pengurangan pecahan.

PEMBELAJARAN BANGUN DATAR MENGGUNAKAN PERMAINAN ANAK TRADISIONAL INDONESIA Ana Muslihatun; Sugiman Sugiman
AKSIOMA: Jurnal Program Studi Pendidikan Matematika Vol 11, No 3 (2022)
Publisher : UNIVERSITAS MUHAMMADIYAH METRO

Kegiatan pembelajaran bangun datar yang hanya menitikberatkan pada prosedur formal, tidak mampu mengembangkan lintasan belajar siswa. Oleh karena itu, pembelajaran bangun datar menggunakan konteks permainan tradisional menjadi salah satu alternatif yang dapat dilakukan. Tujuan penelitian ini adalah untuk mendeskripsikan learning trajectory siswa dalam mengkonstruksikan konsep luas bangun datar dengan menggunakan konteks bentuk papan permainan dam-daman sebagai titik awal pembelajaran. Metode penelitian ini menggunakan penelitian kualitatif berupa design research. Hasil dari penelitian ini adalah serangkaian aktivitas pada tingkat situational, referensial, general, dan formal. Pada tingkat situational, pemahaman awal secara langsung bentuk-bentuk bangun datar menggunakan bentuk papan permainan dam-daman. Tingkat referensial, siswa merepresentasi bentuk bangun apa yang ditemukan pada papan permainan dam-daman melalui representasi gambar. Tingkat general, siswa menghitung luas dari suatu bangun dengan menggunakan satu satuan luas yang telah ditentukan. Terakhir, tingkat formal, siswa merekonstruksi pemahaman mereka untuk menentukan rumus masing-masing luas bangun datar. Simpulan dari penelitian ini menunjukkan bahwa papan permainan dam-daman mampu merangsang siswa dalam mengkonstruksikan konsep luas bangun datar seperti persegi panjang, segitiga, jajar genjang, dan trapesium.
