Abstract

Based on the problems faced in schools from the results of interviews with the lack of student learning outcomes on the circumference and area of ​​flat shapes this is due to the lack of media and approaches used by classroom teachers, so researchers want to improve students' critical thinking skills by developing power point learning media assisted by the Canva application that can help students understand the material and various questions with critical thinking skills, as well as a contextual teaching and learning approach that makes students find out and be active in learning. The research method used is Research and Development from Borg and Gall with the following stages: 1) Research, 2) planning, 3) product development, 4) limited test, 5) Revision, 6) wider test, 7) final product . For the results of the teacher's response, 84% are in good category and 73% are in good enough category. For the results of improving students with the n-gain test, the limited trial was 0.65 and the broad trial was 0.66, including the medium category. The normality test in the limited test is 0.200 and 0.068 while for the broad test it is 0.256 and 0.813 so that the distribution is normal. Paired simples test in limited trials and wide trials 0.000 <0.05 then H0 is rejected, Ha is accepted. So there are significant and effective differences in learning.

Abstract

AbstractThis study identified and analyzed epistemological obstacles experienced by prospective elementary school teachers in solving mathematical literacy tasks on plane geometry material. This study employed a case study method, involving 24 students from a university, which was located in Cimahi City, West Java. The diagnostic test served as the research instrument and the data were analyzed using a thematic analysis approach to uncover various epistemological obstacles encountered by undergraduate students, including misconceptions regarding the properties of plane figures and difficulties in applying geometric concepts to mathematical literacy tasks. Epistemological obstacles arise due to the students' inability to connect abstract concepts with practical contexts, as well as their limited understanding of basic geometric concepts. These obstacles primarily stem from misconceptions about fundamental concepts of plane figures, difficulties in applying geometric concepts in contextual situations, and procedural learning approaches that lack conceptual depth. This research contributes to developing geometry learning strategies at the elementary school level, which can ultimately improve the overall quality of mathematics education.Keywords: epistemological obstacle, mathematical literacy, plane geometry. AbstrakPenelitian ini bertujuan untuk mengidentifikasi dan menganalisis hambatan epistemologis yang dialami oleh mahasiswa calon guru sekolah dasar dalam menyelesaikan tugas literasi matematis pada materi geometri bidang datar. Penelitian ini menggunakan metode studi kasus dengan melibatkan 24 mahasiswa dari sebuah universitas yang berlokasi di Kota Cimahi, Jawa Barat. Test diagnostik digunakan sebagai instrument penelitian, dan data dianalisis menggunakan pendekatan analisis tematik untuk mengungkap berbagai hambatan epistemologis yang dialami oleh mahasiswa, termasuk miskonsepsi terhadap sifat-sifat bangun datar dan kesulitan dalam menerapkan konsep geometri pada tugas literasi matematika. Hambatan epistemologis muncul karena ketidakmampuan mahasiswa dalam menghubungkan konsep-konsep abstrak dengan konteks praktis, serta keterbatasan pemahaman terhadap konsep dasar geometri. Hambatan-hambatan ini terutama berasal dari miskonsepsi mengenai konsep dasar bangun datar, kesulitan dalam menerapkan konsep geometri dalam situasi kontekstual, dan pendekatan pembelajaran prosedural yang kurang mendalam secara konseptual. Penelitian ini memberikan kontribusi terhadap pengembangan strategi pembelajaran geometri di tingkat sekolah dasar, yang pada akhirnya dapat meningkatkan kualitas pendidikan matematika secara keseluruhan.Keywords: hambatan epistemis, literasi matematis, bangun datar.

Abstract

Kegiatan pengabdian ini bertujuan untuk meningkatkan kapasitas guru sekolah dasar dalam mengembangkan modul ajar berbasis literasi kesehatan yang terintegrasi dengan pembelajaran tematik Kurikulum Merdeka. Kegiatan dilaksanakan melalui lima tahapan, yaitu: persiapan, pelatihan, pendampingan teknis, implementasi di kelas, dan evaluasi. Pelatihan diikuti oleh 12 guru dari jenjang kelas 3–5 dan difokuskan pada penguatan konsep literasi kesehatan serta praktik penyusunan modul ajar. Hasil pendampingan menunjukkan bahwa guru mampu mengembangkan sembilan modul ajar yang memuat topik-topik kesehatan seperti kebersihan diri, gizi, dan lingkungan sehat. Modul-modul tersebut telah diimplementasikan di kelas dan mendapat respon positif dari siswa, ditandai dengan meningkatnya keterlibatan dan pemahaman terhadap perilaku hidup sehat. Evaluasi juga menunjukkan peningkatan pemahaman guru terhadap literasi kesehatan dan kemampuan mengintegrasikannya dalam pembelajaran. Kegiatan ini memberikan kontribusi positif terhadap penguatan praktik pembelajaran kontekstual dan membuka peluang keberlanjutan melalui pembentukan komunitas belajar guru berbasis literasi kesehatan.
