Abstract

. Masalah geometri masih dianggap sulit oleh mahasiswa Pendidikan Guru Sekolah Dasar (PGSD), padahal materi geometri diajarkan di setiap level pendidikan dari sekolah dasar sampai perguruan tinggi. Tujuan penelitian ini adalah menganalisis pengetahuan konseptual dan prosedural serta proses berpikir geometris pada mahasiswa PGSD level deduktif dan informal deduktif dalam menyelesaikan masalah geometri. Jenis penelitian yang dilakukan adalah kualitatif, dengan lima orang mahasiswa semester 6 sebagai subjek penelitian. Data dikumpulkan dengan tes awal, tes uraian dan wawancara. Analisis data kualitatif yang digunakan adalah interaktif model menurut Miles & Huberman. Hasil penelitian menunjukkan tiga mahasiswa berada pada level deduktif memiliki pengetahuan konseptual dan prosedural yang benar, baik dan lengkap. Mahasiswa pada level deduktif mampu menalar dengan baik dari permasalahan geometri yang dihadapi dan menunjukkan proses pemecahan masalah geometri yang runtut dan masuk akal. Sedangkan mahasiswa pada informal deduktif, analisis dan visualisasi menunjukkan berpikir yang rumpang dan proses pemecahan masalah yang kurang terorganisasi. Simpulan penelitian ini adalah mahasiswa level deduktif telah memiliki pengetahuan konseptual dan prosedural dalam geometri yang memadai untuk digunakan dalam menyelesaikan masalah geometri.

Abstract

The ethnomathematics approach could complement mathematics learning at all levels of education. This study aims to determine the progress map of the ethnomathematics research. The literature review was carried out from April to May 2021 by searching through the Scopus, Google Scholar, and Crossref database using ‘ethnomathematics’ as the keyword with the help of the VosViewer software. The results showed the development of research and publications on ethnomathematics in the last twelve years (2015 to 2021) from three international databases including Scopus with 200 articles, Crossref with 142 articles, and Google Scholar with 840 articles. The progress map of the ethnomathematics publication based on co-words was grouped into 5 clusters. The authors found four keywords; pedagogy, problem-solving ability, elementary school student, and teaching materials in the collected ethnomathematics publications that can be developed for future research and learning studies at Elementary School Teacher Education Study Program.

Abstract

Permasalahan penting yang dihadapi sekolah inklusi adalah belum banyak pendekatan yang digunakan dalam pembelajaran untuk melayani PDBK (Peserta Didik Berkebutuhan Khusus), belum mengoptimalkan potensi yang dimiliki PDBK. Tantangan bertambah pada saat sekolah diharapkan mendukung implementasi kurikulum merdeka dengan pengembanagn pembelajaran berdiferensiasi.  Tujuannya agar guru kelas memiliki pengetahuan dan keterampilan yang memdai untuk merancang IEP bagi PDBK dengan mengimplementasikan pendekatan mutlisensori. Pelaksanaan kegiatan yang dilakuakn dalam 4 tahap yang mengadopsi pendekatan OL (Organizational Learning), yaitu sosialisasi, eksternalisasi, kombinasi, dan internalisasi. Dimana keempat tahap tersebut dibangun dalam 4 blok bangunan OL. Hasil yang dicapai meliputi: (1) pengetahuan guru tentang IEP dan pembelajaran berdiferensiasi, pendekatan multisensori dan membaca permulaan mencapai 77,8 kategori cukup baik, (2) dihasilkan dan diimplementasikan rancangan IEP bagi PDBK, dari 3 guru kelas mencapai kategori baik. Simpulan dari kegiatan ini adalah IEP dengan pendekatan multisensori dapat membantu guru kelas mewujudkan pelayanan yang optimal bagi PDBK berkesulitan membaca di SD inklusi.

Abstract

This study is motivated by the use of lecture methods that are less preferred by students, low understanding of concepts in plane figure area, and the lack of learning media in learning mathematics. This study aims to describe the implementation of the Problem Based Learning model assisted by puzzle lubang datar media to improve student learning outcomes in the knowledge aspect and describe student learning outcomes in the aspects of attitudes and skills on the material of flat area of flat area of grade V students of Wonolopo 02 State Elementary School. The type of research used is descriptive qualitative. The data collection techniques used were tests and non-tests. Tests in the form of pretests and posttests and non-tests in the form of interviews, observations, attitude assessment rubrics, and skill assessment rubrics. The data analysis technique used was descriptive analysis. The results showed that there was an increase in the average score from pretest to posttest, which amounted to 24.81. The percentage of students who completed also increased, the percentage of pretest students who completed 19.23%, while the percentage of posttest students who completed 73.08%. In the attitude aspect, it reached the good category with the percentage of students who reached the completeness criteria ≥ 3 in the indicators of confidence 76.92% and cooperation 80.77%. In the skill aspect, it also reached the good category with the percentage of students who reached the completion criteria ≥ 3 in the indicators of confidence 76.92%, cohesiveness 73.08%, and delivery of results 76.92%. So that implementing the Problem Based Learning learning model assisted by puzzle lubang datar media in plane figure area for fifth grade students of Wonolopo 02 State Elementary School can improve student learning outcomes in the knowledge aspect and the achievement of student learning outcomes well in the aspects of attitude and skills.
