Pengembangan Media Pembelajaran Matematika “Minitim Kabar” Untuk Meningkatkan Hasil Belajar Kognitif Siswa

Abstract

Weight measurement mathematics was an important material for weighing objects in everyday life. Based on the resulted of observations of students' scores on weight measurement 58% did not reach the KKM (Minimum Completeness Criteria). This study aim to (1) developing Minitim Kabar media for 2nd grade; (2) knowing the feasibility of “Minitim Kabar" media; (3) knowing the increased in cognitive learning outcomes measuring weight in Class II SD students. This research was R&D which includes 10 steps in research which include: research potentials and problems, design data, design validation, revision design, product testing, product revision, usage testing, product revision, product production. The expert tested subjects in this study were the media expert validator and the material expert validator, while the tested subjects were 6 students in the media trial and 9 students in the product trial. Data tested techniques using interviews, observation, tests, and documentation. The data analysis technique used quantitative data analysis techniques and qualitative data analysis. The resulted of this study indicate that the mini media had a high level of validity and attractiveness. The resulted of the validation of material experts were 92.3%, the resulted of the validation of media experts were 87.5%, and the proportion of student questionnaire responses was 100%. The increase in students' cognitive learning outcomes was 45.06. The N-gain test result of 0.65 was at a moderate level. Thus, the Minitim Kabar media was suitable for used as a thematic learning media to improve cognitive learning outcomes in 2nd grade on weight measurement matters.

Role Play Game (RPG) to Improve Student Problem Solving Skills

“…This is backed by the belief (Gumilang et al, 2019) that learning through interactive learning media can enhance problem-solving abilities. According to the findings of research (Ramadani & Oktiningrum, 2020)the use of learning media can enhance students' mathematical skills.. This is because interactive learning media used in the learning process can encourage students to think systematically, beginning with identifying problems, planning strategies, implementing those strategies, drawing conclusions, and evaluating each stage that has been completed.…”

Pengembangan Media “Kanca” (Keseimbangan Angka Ceria) Berbasis Local Culture

“…Penelitian oleh Handayani dan Alamsyah menyatakan bahwa media timbangan dapat meningkatkan aktivitas dan hasil belajar siswa kelas II SD dalam (Ramadani et al, 2020). Oleh sebab itu, peneliti mengembangkan media dengan berbentuk timbangan yaitu "kanca" berbasis local culture yang dapat digunakan sebagai media pembelajaran dan diharapkan dapat membantu siswa lebih memahami materi penjumlahan dan pengurangan.…”

Pengembangan Modul Matematika Berbasis Realistik Terintegrasi Higher Order Thinking Skills (Hots) Pada Materi Bangun Ruang

“…Seperti yang diutarakan oleh Rusmana & Kurniawarsih (2020: 40) bahwa media pembelajaran merupakan sebuah alat peraga yang digunakan untuk mempermudah siswa dalam mempelajari hal yang abstrak melalui perantara benda konkret. Sedangkan media pembelajaran menurut Ramadani & Oktiningrum (2020) mengatakan bahwa suatu alat bantu/instrumen yang digunakan sebagai perantara untuk menyampaikan pesan atau materi pembelajaran kepada siswa agar lebih mudah dimengerti. Berdasarkan beberapa pendapat di atas, dapat disimpulkan bahwa media pembelajaran merupakan segala bentuk bahan, alat, atau segala sumber daya yang digunakan guru untuk menyampaikan materi guna membantu merangsang pikiran dan kemampuan siswa dalam proses belajar mengajar.…”
