Abstract

Pandemi COVID-19, menyebabkan  penurunan pembelajaran yang signifikan khususnya pada mata pelajaran matematika. Kegiatan belajar mengajar memerlukan media pendidikan yang dapat membangkitkan perhatian dan ketertarikan siswa terhadap materi. Berdasarkan hal tersebut, penting untuk mengamati pengaruh penggunaan media terhadap pembelajaran matematika terutama pada materi penjumlahan dan pengurangan operasi bilangan bulat. Kalkulator operasi bilangan bulat (Kopi Ulat) adalah salah satu alat pembelajaran matematika yang dapat digunakan dalam materi operasi penjumlahan dan pengurangan pada bilangan bulat. Dengan memanfaatkan Kopi Ulat, siswa mendapatkan pengalaman langsung dalam menjumlahkan dan mengurangkan bilangan bulat kecil. Penelitian ini bertujuan untuk melihat pengaruh penggunaan Kopi Ulat pada hasil belajar. Penelitian ini dilakukan pada siswa kelas 4 SD Negeri 04 Segaran sebanyak 19 siswa. Hasil penelitian menunjukkan bahwa penggunaan Kopi Ulat dalam pembelajaran matematika di kelas mampu meningkatkan hasil belajar operasi penjumlahan dan pengurangan operasi bilangan bulat. Hal ini dibuktikan dengan naiknya persentase ketuntasan siswa. Melalui media Kopi ulat, siswa juga mampu merumuskan langkah-langkah operasi penjumlahan dan pengurangan bilangan bulat, mampu membedakan  bilangan positif maupun negatif, serta lebih mudah dalam menyelesaikan soal.

Abstract

The implementation of mathematics learning in class X of SMK As-Salam revealed that students have difficulty in understanding mathematical concepts because learning methods are predominantly conventional and lack the connection of material to real life. Therefore, an e-LKPD based on live worksheets with contextual problems was developed. This study focuses on testing the validity, practicality, and effectiveness of the e-LKPD based on Liveworksheets. This study aims to develop a contextual e-LKPD based on live worksheets to increase the learning motivation of mathematics students in class X at SMK As-Salam. The research method used is the ADDIE (Analysis, Design, Development, Implementation, Evaluation) development model. The developed e-LKPD was validated by experts and tested for practicality through teacher and student responses. The validation results showed that the e-LKPD fell into the highly valid category with a score of 3.668. The product's effectiveness was tested using a paired sample t-test. Based on the analysis of data from 31 students, the average learning motivation score was 51% before treatment and 66% after treatment. The calculated t-value was -3.655, indicating that the e-LKPD is effective, and the sig. (2-tailed) value was 0.000, which is less than 0.05. Therefore, there was a significant increase in student learning motivation after using the e-LKPD. The conclusion of this study shows that contextualized e-LKPD based on live worksheets is effective in increasing students' motivation to learn exponent material. Therefore, it is expected that this e-LKPD can be used as an alternative to innovative learning media to improve the quality of mathematics learning.
