Abstract

This study aims to develop a valid and practical Interactive Multimedia-Based Student Worksheet (LKS) to foster students’ mathematical creative thinking skills. The research adopts a development research design using the ADDIE model, which includes the stages of Analysis (curriculum, students, and learning material), Design, Development, Implementation, and Evaluation. Instruments used in this study consist of validation sheets for learning tools and student response questionnaires for measuring practicality. The research was conducted at SMA Negeri 6 Bengkulu City with Grade X students during the 2024/2025 academic year, focusing on the topic of arithmetic sequences and series. The results demonstrate that the developed interactive multimedia-based LKS is both valid and practical. Expert validation results indicate that the material aspect achieved an average score of 3.61 and the media aspect achieved 3.67, both categorized as “highly appropriate.” In terms of practicality, analysis of student response questionnaires yielded a score of 78.3%, which also falls into the “highly practical” category. These findings suggest that the developed LKS is a feasible and effective tool for enhancing students’ mathematical creative thinking skills in secondary education settings.

Abstract

Mathematical literacy focuses on students' ability to analyze, solve, and interpret mathematical problems in a variety of contexts. These abilities need to be measured so that they can be a reference to find ways to improve students' mathematical literacy skills. The shift to an independent curriculum can be a new gateway for learning in Indonesia to improve students' mathematical skills. The purpose of this study is to determine the mathematical literacy ability of grade VII students of SMP Negeri 21 Bengkulu Tengah in implementing the independent curriculum. This study investigated 25 students who used the independent curriculum. As a method of data collection, written tests, interviews, and documentation were used. The results of the study show that most students are still at a low level of mathematical literacy. 8 students reached level 1c, 2 students were at level 1b, and only 1 student reached level 1a. On the PISA scale, level 1c is the lowest level, where students can only answer questions with very explicit information, while level 3 shows the ability to use reasoning and apply mathematical concepts in more complex contexts. This low achievement is influenced by the lack of habit of solving contextual problems, difficulty understanding the information in the problem, and limited ability in basic calculation operations. These findings show the need for improvement in the approach to mathematics learning with an emphasis on contextual problems, and the practice of applied numeracy skills. Literasi matematis berfokus pada kemampuan siswa untuk menganalisis, memecahkan, dan menafsirkan masalah matematis dalam berbagai konteks. Kemampuan tersebut perlu diukur sehingga dapat menjadi acuan untuk mencari cara bagaimana meningkatkan kemampuan literasi matematis siswa. Pergeseran ke kurikulum merdeka dapat menjadi gerbang baru bagi pembelajaran di Indonesia untuk meningkatkan kemampuan matematis siswa. Tujuan penelitian ini adalah untuk mengetahui kemampuan literasi matematis siswa kelas VII SMP Negeri 21 Bengkulu Tengah dalam menerapkan kurikulum merdeka. Penelitian ini menyelidiki 25 siswa yang menggunakan kurikulum merdeka. Sebagai metode pengumpulan data digunakan tes tertulis, wawancara, dan dokumentasi. Hasil penelitian menunjukkan bahwa sebagian besar siswa masih berada pada level literasi matematis rendah. 8 siswa mencapai level 1c, 2 siswa berada di level 1b, dan hanya 1 siswa mencapai level 1a. Dalam skala PISA, level 1c merupakan tingkat terendah, di mana siswa hanya dapat menjawab soal dengan informasi yang sangat eksplisit, sedangkan level 3 menunjukkan kemampuan menggunakan penalaran dan menerapkan konsep matematika dalam konteks yang lebih kompleks. Rendahnya capaian ini dipengaruhi oleh kurangnya kebiasaan menyelesaikan soal kontekstual, kesulitan memahami informasi dalam soal, serta terbatasnya kemampuan dalam operasi hitung dasar. Temuan ini menunjukkan perlunya perbaikan dalam pendekatan pembelajaran matematika dengan menekankan pada soal-soal kontekstual, dan latihan keterampilan berhitung yang aplikatif.
