Abstract

This study aims to develop and validate the In Action learning design guidebook for mathematics in junior high school, as well as test teachers' responses to the guidebook. The research method refers to the Plomp development model, which includes the Preliminary Research Phase, Prototyping Phase, and Assessment Phase. The instruments used were design book assessment sheets, expert response questionnaires, and teacher response questionnaires. The results of the study based on expert validation analysis at the Assessment Phase stage showed that all indicators in the guidebook were in the valid and very valid categories (average assessment ranged from 3.17 to 3.63), indicating the feasibility of the product for implementation. Teacher response trials showed "very positive" results on small group tests (majority of aspects above 75%) and increased on field group tests (most aspects above 86%). However, there are inputs for design simplification, more in-depth explanations, and continuous assistance for usage optimization. Overall, this guidebook meets the eligibility criteria and can be implemented with several improvements based on the teacher's input to improve practicality and readability.  Keywords: Learning design, In Action, Mathematical connections, Mathematics, Teacher response.   Penelitian ini bertujuan untuk mengembangkan dan memvalidasi guidebook  desain pembelajaran In Action untuk matematika di SMP, serta menguji respon guru terhadap guidebook  tersebut. Metode penelitian mengacu pada model pengembangan Plomp, yang meliputi tahapan Preliminary Research, Prototyping Phase, dan Assessment Phase. Instrumen yang digunakan adalah lembar penilaian buku desain, angket respon ahli, dan angket respon guru. Hasil penelitian berdasrkan analisis validasi ahli pada tahap Assessment Phase menunjukkan bahwa semua indikator pada guidebook  berada dalam kategori valid dan sangat valid (rata-rata penilaian berkisar antara 3.17 hingga 3.63), menunjukkan kelayakan produk untuk diimplementasikan. Uji coba respon guru menunjukkan hasil yang "sangat positif" pada uji kelompok kecil (mayoritas aspek di atas 75%) dan meningkat pada uji kelompok lapangan (sebagian besar aspek di atas 86%), mengindikasikan keunggulan, kesesuaian kebutuhan, serta kemudahan penggunaan dan implementasi guidebook . Meskipun demikian, terdapat masukan untuk penyederhanaan desain, penjelasan lebih mendalam, serta pendampingan berkelanjutan untuk optimalisasi penggunaan. Secara keseluruhan, guidebook  ini memenuhi kriteria kelayakan dan dapat diimplementasikan dengan beberapa penyempurnaan berdasarkan masukan guru untuk meningkatkan kepraktisan dan keterbacaan.  Kata Kunci: Desain pembelajaran, In Action, Koneksi matematis, Matematika, Respon guru

Abstract

This study aims to conduct an in-depth analysis of the impact of the learning environment on students’ low understanding of mathematical concepts, particularly in algebra topics among junior high school students. The learning environment is an essential factor that plays a major role in determining students’ success in comprehending abstract mathematical concepts that require logical thinking skills. This research employs a theoretical review or literature study method by examining various scholarly sources such as journals, books, and previous research findings relevant to the topic. Data collection techniques were carried out through analysis, comparison, and synthesis of information from various references. The results of the study indicate that the condition of the learning environment, both physical and non-physical, has a significant influence on students’ understanding of algebraic material. Factors such as classroom noise, inadequate lighting, limited learning facilities, low motivation, and less conducive social interactions have been proven to reduce students’ concentration and interest in learning mathematics. Therefore, it can be concluded that efforts to improve students’ understanding of mathematical concepts must be accompanied by creating a comfortable, interactive, and creative learning environment that motivates students to think critically and participate actively in the learning process.
