Abstract

Menurunnya kemampuan akademis di bidang matematika dan munculnya kecemasan matematika di benak siswa merupakan dampak dari memahami konsep-konsep matematika dengan pembelajaran daring. Kegiatan workshop ini bertujuan untuk membantu dan meningkatkan kemampuan guru dalam merancang media pembelajaran yang menyenangkan bagi generasi digital menuju tatanan kehidupan baru dan memfasilitasi guru agar mampu menganalisis kecemasan matematika yang dialami siswa dan mampu mengatasinya agar siswa dapat belajar dengan optimal. Pelaksanaan kegiatan pengabdian dilakukan mulai tanggal 25 s.d. 27 Oktober 2020 secara daring (online) melalui aplikasi Zoom Cloud Meetings. Kegiatan ini melibatkan 17 orang guru Sekolah Dasar di Kota Bandar Lampung. Guru mengungkapkan hasil belajar siswa dalam pembelajaran daring sebanyak 53% kurang memuaskan. Guru pun mengutarakan mengatasi siswa yang kesulitan dalam pembelajaran matematika dengan memberikan bimbingan, perhatian khusus dan mengulang-ulang penjelasan. Setelah guru mengikuti pemaparan materi dan penyusunan media pembelajaran yang mendukung pembelajaran menyenangkan untuk mengatasi kecemasan matematis, 82% guru mengungkapkan lebih mudah menyusun lagu matematika, dikarenakan mudah dikaitkan dengan lagu yang dikenal anak-anak. Wawasan guru dalam media pembelajaran matematika harus lebih beragam lagi. Penyusunan media pembelajaran selanjutnya diperlukan secara digital mengingat tatanan kehidupan baru semenjak terjadinya pandemi Covid-19. DOI: https://doi.org/10.23960/rp/v1i2.hal.96-99

Abstract

Mathematical communication skills are essential for students to develop in mathematics learning. These skills involve expressing ideas, explaining problem-solving procedures, and constructing logical arguments systematically. However, observations and interviews at SMP Negeri 9 Metro revealed that students' mathematical communication skills remain low. They struggle to write mathematical models, represent problems visually, and convert contextual situations into appropriate mathematical symbols or notations. This condition is further aggravated by teacher-centered learning and using less engaging and contextual media. This study examines the effectiveness of Student Worksheets (LKPD) based on Problem-Based Learning (PBL) in improving students' mathematical communication skills. The research employed a quasi-experimental method with a post-test only control group design. The sample consisted of two eighth-grade classes selected through purposive random sampling: class VIII F, which used the LKPD before revision, and class VIII D, which used the LKPD after revision. The research instrument was a mathematical communication test, while the data were analyzed using the Mann-Whitney test. The results showed no significant difference in students' mathematical communication skills between the classes before and after the revision of the PBL-based LKPD, with a significance value of 0.876 (> 0.05). These findings indicate that the revised LKPD has not yet fully incorporated elements that support communication skills, such as tasks promoting discussion, written and oral expression, and adequate visual representation. Therefore, future development of LKPD should integrate real-life contexts, engaging visualization, and collaborative activities to enhance students' ability to communicate mathematical ideas. Keterampilan komunikasi matematis merupakan kompetensi penting yang harus dimiliki peserta didik dalam pembelajaran matematika. Keterampilan ini mencakup kemampuan mengungkapkan ide, menjelaskan prosedur pemecahan masalah, serta menyusun argumen logis secara sistematis. Namun, hasil observasi dan wawancara di SMP Negeri 9 Metro menunjukkan bahwa kemampuan komunikasi matematis peserta didik masih rendah. Mereka mengalami kesulitan dalam menuliskan model matematika, merepresentasikan masalah secara visual, serta mengubah situasi kontekstual menjadi simbol atau notasi yang sesuai. Kondisi ini diperburuk oleh pembelajaran yang berpusat pada guru serta penggunaan media yang kurang menarik dan kontekstual. Penelitian ini bertujuan menguji efektivitas Lembar Kerja Peserta Didik (LKPD) berbasis Problem Based Learning (PBL) untuk meningkatkan kemampuan komunikasi matematis. Metode penelitian yang digunakan adalah eksperimen semu dengan desain post-test only control group. Sampel terdiri dari dua kelas VIII yang dipilih melalui purposive random sampling, yakni kelas VIII F sebagai kelompok yang menggunakan LKPD sebelum revisi dan kelas VIII D sebagai kelompok yang menggunakan LKPD setelah revisi. Instrumen penelitian berupa tes kemampuan komunikasi matematis, dengan analisis data menggunakan uji Mann-Whitney. Hasil penelitian menunjukkan tidak terdapat perbedaan signifikan antara kemampuan komunikasi matematis peserta didik pada kelas sebelum dan sesudah revisi LKPD berbasis PBL, dengan nilai signifikansi 0,876 (> 0,05). Temuan ini menunjukkan bahwa revisi LKPD belum optimal dalam memuat unsur yang mendukung pengembangan komunikasi matematis, seperti penugasan diskusi, penyampaian ide secara tertulis maupun lisan, dan representasi visual. Oleh karena itu, pengembangan LKPD selanjutnya perlu mempertimbangkan integrasi konteks nyata, visualisasi menarik, serta aktivitas kolaboratif agar peserta didik dapat berlatih mengomunikasikan ide matematika secara efektif.

Abstract

This study aims to analyze classroom discourse within the didactical design of linear equations in one variable, focusing on the development of students’ critical thinking skills. The research employed a qualitative approach with an evaluative design. The main participants consisted of one mathematics teacher and 12 seventh-grade students (class VII-1) from a public junior high school in Bandar Lampung during the first semester of the 2024/2025 academic year. The students were grouped according to their mathematical abilities into high, medium, low, and mixed categories. Based on secondary data, the majority of the class consisted of students with low academic ability. Data were collected through observation, interviews, and documentation, while validity was ensured using triangulation techniques. Data analysis was conducted in three stages: data condensation, data display, and conclusion drawing and verification. The findings indicate that (1) the most dominant form of classroom discourse produced by students was questions and answers, highlighting the importance of designing learning activities that facilitate complex questioning and answering to support the development of students’ critical thinking skills; (2) the most frequently observed indicator of critical thinking in classroom discourse was evaluation; and (3) students with medium-level mathematical ability were the most dominant in generating classroom discourse, which was influenced by factors of comfort.
