PENGEMBANGAN LEMBAR KERJA SISWA BERBASIS CHALLENGE BASED LEARNING (CBL) MENGGUNAKAN AUTOGRAPH UNTUK MENINGKATKAN KEMAMPUAN NUMERASI

Abstract

Numerasi merupakan kecakapan yang diperlukan di abad ke-21, Namun faktanya, kemampuan numerasi siswa Indonesia masih terhitung rendah. Penelitian ini bertujuan untuk mengembangkan lembar kerja siswa model Challenge Based Learning (CBL) pada topik program linear berbantuan Autograph sebagai upaya untuk meningkatkan kemampuan numerasi siswa. Penelitian ini dilakukan di Madrasah Darus-Sunnah, melibatkan 16 siswa kelas XI tahun ajaran 2021/2022. Metode penelitian yang diaplikasikan adalah penelitian dan pengembangan 3-D dengan langkah Define, Design, dan Develop. Teknik analisis data yang digunakan adalah deskriptif kualitatif dan analisis deskriptif kuantitatif. Hasil penelitian menunjukkan bahwa lembar kerja siswa menggunakan model CBL dinyatakan valid, berdasarkan penilaian ahli. Penskoran kevalidan prototipe pengembangan lembar kembar kerja siswa model CBL menggunakan Autograph sebesar 93%, lembar kerja siswa sebesar 92%, dan instrumen kemampuan numerasi dalam kategori valid. Selanjutnya lembar kerja siswa memenuhi kritera praktis berdasarkan respon siswa sebesar 92%. Demikian pula lembar kerja siswa tergolong efektif yang terlihat dari adanya peningkatan rata-rata kemampuan numerasi siswa dari sebelum menggunakan lembar kerja siswa model CBL sebesar 32 menjadi 52 (p-value = 0,001) setelah diaplikasikannya lembar kerja siswa model CBL. Kesimpulan penelitian ini adalah lembar kerja siswa model CBL menggunakan Autograph telah valid, praktis, dan efektif sehingga dapat digunakan untuk meningkatkan kemampuan numerasi. Numeracy is a necessary skill in the 21st century. However, in fact, the numeracy skills of Indonesian students are still relatively low. This research aims to develop model student worksheetsChallenge Based Learning (CBL) in linear programming material assisted by Autograph as an effort to improve students' numeracy skills. This research was conducted at Madrasah Darus-Sunnah, involving 16 class XI students for the 2021/2022 academic year. The research method applied is 3-D research and development with steps Define, Design, and Develop. The data analysis technique used is descriptive qualitative and quantitative descriptive analysis. The research results showed that: student worksheets using the CBL model were declared valid, based on expert assessment. The validity scoring of the CBL model student worksheet development prototype using Autograph was 93%, the student worksheet was 92%, and the numeracy ability instrument was in the valid category. Furthermore, the student worksheet meets practical criteria based on student responses of 92%. Likewise, student worksheets are classified as effective, which can be seen from the increase in the average student numeracy ability from before using the CBL model student worksheets, which was 32 to 52 (p-value = 0.001) after applying the CBL model student worksheet. The conclusion of this research is that the CBL model student worksheets using Autograph are valid, practical and effective so they can be used to improve numeracy skills.
