Abstract

Salah satu strategi untuk melakukan pembuktian geometri adalah strategi two-column proof atau dikenal sebagai strategi pembuktian dua kolom. Guru-guru matematika di Kabupaten Musi Banyuasin masih menghadapi kesulitan untuk melakukan pembuktian geometri, hal tersebut dikarenakan kurangnya pemahaman konsep dasar pembuktian geometri, keterbatasan sumber belajar, serta kurangnya dukungan dari lingkungan belajar. Padahal, untuk dapat mendampingi peserta didik dalam melakukan pembuktian geometri, guru perlu memahami dengan baik materi pembuktian geometri. Mengingat pentingnya peran guru dalam mengajarkan pembuktian geometri, Prodi Pendidikan Matematika FKIP Universitas Sriwijaya melaksanakan program Pengabdian kepada Masyarakat (PkM) yang bertujuan untuk melatih dan memberikan pengalaman kepada guru matematika tentang pembuktian geometri melalui kegiatan pelatihan secara synchronous maupun asynchronous. Adapun peserta PkM ini adalah guru-guru Matematika yang tergabung dalam kelompok MGMP Matematika Kabupaten Musi Banyuasin sejumlah 15 orang. Berdasarkan kegiatan PkM dapat disimpulkan bahwa: (1) secara umum terdapat peningkatan kemampuan pembuktian geometri guru peserta PkM setelah mengikuti kegiatan pelatihan, (2) kemampuan pembuktian geometri guru peserta PkM termasuk dalam kategori level 3 dan level 4 Van Hiele, yakni Informal Deduction dan Deduction, serta (3) adanya respon yang sangat baik terhadap kegiatan PkM. Tindak lanjut dari kegiatan ini adalah disarankan untuk menerapkan strategi two-column proof dalam pembelajaran pembuktian geometri dengan peserta didik secara berkelanjutan.

Abstract

Pemecahan masalah matematika merupakan satu kemampuan yang harus dimiliki peserta didik untuk menyelesaikan soal-soal level Higher Order Thinking Skill (HOTS). Rendahnya kemampuan pemecahan masalah matematika peserta didik di Indonesia disebabkan salah satunya karena peserta didik belum terbiasa menyelesaikan soal-soal pemecahan masalah. Selain itu, dalam buku cetak, referensi, atau LKPD yang digunakan peserta didik belum berbasis pemecahan masalah. Kegiatan Pengabdian kepada Masyarakat (PkM) berupa pendampingan yang bertujuan untuk mendukung Musyawarah Guru Mata Pelajaran (MGMP) Matematika dalam merancang LKPD berbasis pemecahan masalah yang dapat digunakan peserta didik. Kegiatan ini dilaksanakan di SMKN 1 Kayuagung, Kabupaten Ogan Komering Ilir, Provinsi Sumatra Selatan. Kegiatan ini diikuti oleh 23 Sekolah Menengah Atas dan sederajat dari Kabupaten Ogan Komering Ilir. Metode yang digunakan adalah deskriptif kualitatif. Kegiatan pendampingan ini dilakukan dengan tiga tahapan yakni, tahap persiapan, tahap pelaksanaan, dan tahap evaluasi. Hasil kegiatan pendampingan MGMP Matematika dalam merancang LKPD berbasis pemecahan masalah menunjukkan ketercapaian kegiatan sebesar 86,67%. Di mana indikator ketercapaian pelatihan tertinggi terletak pada materi PkM yang diberikan dalam bentuk kegiatan pendampingan MGMP Matematika dalam merancang LKPD berbasis pemecahan masalah telah sesuai dengan kebutuhan peserta. Kegiatan PkM ini menghasilkan LKPD berbasis pemecahan masalah yang dapat digunakan untuk pembelajaran bagi peserta didik.

Abstract

The Basic Calculus course is one of the compulsory courses that must be mastered by prospective mathematics teachers. This study aims to analyze the errors in the topic of Continuity in terms of prospective mathematics teachers’ ability to (1) interpret function graphs, (2) draw functions, and (3) utilize relevant concepts to construct written solutions. This is a descriptive study involving 27 second-semester of prospective mathematics teachers enrolled in Basic Calculus course as the subject of the study. Data were collected through written tests to all subjects, and interviews to selected subjects. The analysis of students' written answers revealed five types of errors: (1) errors in reading function graphs, (2) errors in sketching function graphs, (3) errors in determining the limit value of functions, (4) errors in understanding the concept of division by zero, and (5) errors in using the concept of Continuity. The findings of this study indicate that 66.67% of prospective mathematics teachers continue to demonstrate a limited proficiency in reading function graphs, 59.26% of students exhibit a lack of competence in function sketching, and 25.93% of students have a low level of ability in utilizing concepts to construct written solutions.

Abstract

Understanding the concept of whole number operations, especially addition and subtraction, is an important basis in mathematics that must be mastered by students. However, many students still experience difficulties in understanding the material, especially in more complex operations. This study aims to analyze students' concept understanding ability on whole number operation material by applying the demonstration method. The research method used was descriptive qualitative, involving 26 students of class VII.A at Srijaya Negara Junior High School Palembang as research subjects. Data was collected through written tests consisting of five description questions and interviews to explore students' understanding more deeply. The results showed that 47.62% of students scored in the high category, 14.28% in the medium category, and 38.09% in the low category, with an average score of 59.05 which indicates understanding in the medium category. The application of the demonstration method, in which students actively participated by walking on the marked tiles, proved to increase students' enthusiasm and provide a more memorable learning experience. Nonetheless, the proportion of students in the low category indicates the need for more attention in the learning process. This study concludes that the demonstration method is effective in improving concept understanding, but needs to be balanced with additional approaches to support students who have difficulty in understanding integer operation material.
