Introduction

Pengembangan media jawa (jagoan waktu) untuk mengatasi miskonsepsi materi waktu kelas 2 sdn candi 01 semarang. Penelitian ini mengembangkan media JAWA (Jagoan Waktu) yang efektif & layak untuk atasi miskonsepsi materi waktu pada siswa kelas 2 SD. Terbukti tingkatkan hasil belajar matematika.

Abstract

Tujuan yang hendak dicapai dalam penelitian ini adalah untuk mengetahui keefektifan dan kelayakan media JAWA (Jagoan Waktu) dalam membantu siswa untuk membaca waktu. Jenis penelitian ini adalah penelitian dan pengembangan pada produk (Research and Development). Penelitian penelitian ini menghasilkan produk berupa media JAWA (Jagoan Waktu) untuk mengatasi miskonsepsi materi waktu kelas 2 SDN Candi 01 Semarang. Teknik analisis yang digunakan yaitu deskriptif kualitatif dan kuantitatif. Instrument yang digunakan berupa angket angket penilaian validasi media, validasi materi, respon siswa, tes (pretest dan posttest). Hasil ujian keefektifan mendapat nilai signifikan dari SDN Candi 01 Semarang sebesar 0,000. Disimpulkan bahwa terdapat pengaruh pada keefektifan media JAWA (Jagoan Waktu) terhadap hasil belajar siswa. Hasil validasi media diperoleh hasil nilai rata-rata kevalidan sebesar 97%. Kemudian dilanjutkan validasi materi diperoleh hasil nilai rata-rata sebesar 94%. Kesimpulannya bahwa media pembelajaran JAWA (Jagoan Waktu) efektif dan sangat layak digunakan untuk pembelajaran matematika materi mengenal waktu. Berdasarkan hasil penelitian ini saran yang dapat disampaikan adalah media JAWA (Jagoan Waktu) dapat digunakan menjadi media pembelajaran yang baru dan inovatif.

Review

This paper presents an intriguing investigation into the development and evaluation of an innovative learning medium, JAWA (Jagoan Waktu), specifically designed to address common misconceptions in understanding time among second-grade students. The research employs a robust Research and Development (R&D) methodology, aiming to ascertain the effectiveness and feasibility of this new media in improving students' ability to read time. Addressing fundamental mathematical concepts at an early age is crucial, and the focus on "miskonsepsi" (misconceptions) indicates a targeted and pedagogically relevant approach, promising a tangible solution to a pervasive learning challenge. The methodology adopted is a commendable blend of descriptive qualitative and quantitative analysis, providing a comprehensive assessment of the JAWA media. Key instruments included pre- and post-tests to gauge learning outcomes, alongside questionnaires for media validation, material validation, and student responses. The results are particularly compelling, with the effectiveness test yielding a statistically significant value of 0.000, strongly suggesting a positive influence of JAWA media on student learning outcomes. Furthermore, the high validation scores—97% for media validity and 94% for material validity—underscore the quality and appropriateness of the developed tool. These findings collectively support the conclusion that JAWA media is both effective and highly feasible for teaching time concepts in mathematics. While the study provides strong evidence for the effectiveness and feasibility of the JAWA media within its specific context (Grade 2 at SDN Candi 01 Semarang), its primary limitation lies in its localized scope. The encouraging results warrant further research to explore the generalizability of these findings across different schools, student demographics, and potentially other grade levels or learning difficulties. Future studies could also delve deeper into the specific pedagogical mechanisms through which JAWA media alleviates misconceptions, perhaps through qualitative observations of student-media interaction. Nevertheless, this research successfully introduces a promising and innovative educational tool, offering a valuable contribution to improving early mathematics education and setting a strong foundation for future advancements in media-supported learning.
