Abstract

Penelitian ini bertujuan untuk mengkaji pengaruh model pembelajaran Picture and Picture terhadap pemahaman konseptual dan prestasi belajar matematika peserta didik. Penelitian ini menggunakan pendekatan kuantitatif dengan desain kuasi-eksperimen post-test only control group. Subjek penelitian terdiri atas 58 peserta didik kelas VIII yang dibagi ke dalam kelompok eksperimen dan kelompok kontrol. Data dikumpulkan melalui tes uraian untuk mengukur pemahaman konseptual dan prestasi belajar matematika. Data dianalisis menggunakan one-way Multivariate Analysis of Variance (MANOVA). Hasil penelitian menunjukkan adanya perbedaan multivariat yang signifikan antara kedua kelompok, dengan peserta didik pada kelompok eksperimen memperoleh skor pemahaman konseptual dan prestasi belajar matematika yang lebih tinggi dibandingkan kelompok kontrol. Temuan ini menunjukkan bahwa penggunaan gambar berurutan secara terstruktur dalam model pembelajaran Picture and Picture mampu meningkatkan pemahaman konseptual sekaligus mendukung peningkatan prestasi belajar matematika peserta didik pada jenjang Sekolah Menengah Pertama. This study aimed to examine the effect of the Picture and Picture learning model on students’ conceptual understanding and mathematics achievement. A quantitative approach was employed using a quasi-experimental post-test only control group design. The participants consisted of 58 eighth-grade students divided into an experimental group and a control group. Data were collected through open-ended test items designed to assess conceptual understanding and mathematics achievement. The data were analyzed using one-way Multivariate Analysis of Variance (MANOVA). The results revealed a significant multivariate difference between the two groups, with students in the experimental group achieving higher scores in both conceptual understanding and mathematics achievement than those in the control group. These findings indicate that the structured use of sequential images in the Picture and Picture learning model supports students in organizing mathematical ideas and contributes to improved mathematics achievement at the junior high school level.

Abstract

This study aims to describe the alignment of hypothetical learning trajectories (HLT) in SPLTV designed with the actual learning processes that occur in the classroom and the reasoning processes students go through in understanding SPLTV. This present study is the result of the first cycle of the design research method with three stages, namely preliminary design, teaching experiment, and retrospective analysis. Data collection was carried out through interviews with teachers and students, observation in the classroom, study of students' answer sheets during the teaching experiment, and analysis of photos or videos taken during the research. Data analysis was conducted by using data triangulation, which involves comparing the HLT designed as a reference with the actual learning that occurred and reviewing the results of observations, documentation, digital footprints, and interviews. The research findings indicate that students’ learning trajectories develop through levels of thinking, from understanding basic algebraic concepts to discovering formal procedures for solving SPLTV. The study concludes that HLT, designed as a local learning instruction theory, can provide students’ reasoning paths and prove that appropriate instructional design supports the process of independent rediscovery without neglecting the necessary levels of understanding.

Abstract

Penelitian ini bertujuan untuk mengembangkan media pembelajaran berbasis Canva Site pada materi Bangun Ruang Sisi Datar serta menganalisis tingkat validitas, kepraktisan, dan peningkatan kemampuan representasi matematis murid. Canva Site ini berbentuk microsite yang dirancang untuk menyajikan pembelajaran secara menarik dan mudah diakses dalam satu halaman. Metode yang digunakan adalah penelitian dan pengembangan (Research and Development) dengan model ADDIE yang meliputi tahap analisis, desain, pengembangan, implementasi, dan evaluasi. Subjek penelitian melibatkan 20 murid kelas VIII di salah satu SMP di Kabupaten Garut. Instrumen penelitian terdiri atas angket validasi ahli materi dan media, angket respons murid, serta tes pretes dan postes kemampuan representasi matematis. Hasil penelitian menunjukkan bahwa media pembelajaran berbasis Canva Site memiliki tingkat validitas sangat tinggi, dengan persentase validasi materi sebesar 89,95% dan validasi media sebesar 90,17%. Tingkat kepraktisan media berada pada kategori sangat praktis dengan persentase 84%. Selain itu, kemampuan representasi matematis murid mengalami peningkatan dengan nilai rata-rata gain sebesar 0,40 yang termasuk kategori sedang. Hasil ini menunjukkan bahwa media pembelajaran berbasis Canva Site layak dan efektif digunakan dalam pembelajaran matematika. This study aimed to develop Canva Site-based learning media for the topic of polyhedrons and to examine its validity, practicality, and effectiveness in improving students’ mathematical representation ability. This Canva Site takes the form of a microsite designed to present learning content in an engaging and easily accessible single page. The research employed a Research and Development approach using the ADDIE model, which consists of analysis, design, development, implementation, and evaluation stages. The participants were 20 eighth-grade students from a junior high school in Garut Regency. Data were collected through expert validation questionnaires for material and media, student response questionnaires, and pre-test and post-test instruments on mathematical representation ability. The results indicated that the developed Canva Site-based learning media achieved very high validity, with material validation reaching 89.95% and media validation 90.17%. The practicality level was categorized as very practical, with a percentage of 84%. Furthermore, students’ mathematical representation ability showed a moderate improvement, indicated by an average gain score of 0.40. These findings suggest that Canva Site-based learning media are valid, practical, and effective in enhancing students’ mathematical representation ability.
