Abstract

Analisis bibliometrik merupakan analisis yang mendeskripsikan dan membuat peta struktural penelitian ilmiah yang dikumpulkan dari metadata artikel/jurnal. Tujuan dari penelitian analisis bibliometrik ini adalah untuk mengidentifikasi peluang dan perkembangan tren penelitian terkait pengembangan e-modul berbasis STEM terhadap kemampuan berpikir kritis dalam pembelajaran matematika. Metode penelitian yang digunakan adalah metode bibliometrik dengan mengumpulkandata publikasi tahun 2019-2024 melalui website Google Scholar berbantuan software Publish or Perish dengan kata kunci Stem, critical thinking, modul, mathematics, geometry. Analisis data bibliometrik menggunakan software VOS Viewer dengan menampilkan 3 visualisasi yaitu network visualization, overlay visualization, dan density visualization. Hasil penelitian menunjukkan dari 996 jumlah minimun tampilan kata dari kata kunci terkait yang memenuhi ambang atas hanya 127 sedangkan yang terpilih adalah sebanyak 76 kata. Berdasarkan hasil analisis bibliometrik variabel yang berhubungan dengan kemampuan berpikir kritis matematis yang mempunyai peluang dan inovasi untuk penelitian selanjutnya adalah stem module, stem learning, geometric, critical thinking ability, e-module, virtual reality, stem approach dan student critical thinking.

Abstract

Penelitian ini bertujuan untuk mendeskripsikan cara efektifitas Lembar Kerja Peserta Didik (LKPD) dengan model Discovery Learning berbasis indikator pemahaman konsep peserta didik kelas VIII pada materi teorema Pythagoras. Penelitian ini adalah penelitian pengembangan (Research and Development) dengan prosedur 4-D yaitu tahap pendefinisian (define), tahap perancangan (design), tahap pengembangan (develop). Uji efektifitas LKPD dilakukan di kelas VIIIB SMP N 02 Kota Bengkulu dengan jumlah siswa 36 orang pada semester genap tahun ajaran 2019/2020. Instrumen penelitian ini adalah lembar efektifitas LKPD berupa aktivitas peserta didik, respon peserta didik dan hasil belajar peserta didik. Hasil penelitian menunjukkan bahwa LKPD sangat efektif karena LKPD memiliki langkah – langkah yang memuat indikator pemahaman konsep yaitu : a) menyatakan ulang konsep; b) mengklasifikasikan objek menurut sifat-sifat tertentu sesuai dengan konsepnya; c) memberi contoh dan bukan contoh dari suatu konsep; d) menyajikan konsep dalam berbagai bentuk representasi matematis; e) mengembangkan syarat perlu dan syarat cukup dari suatu konsep; f) menggunakan dan memanfaatkan serta memilih prosedur atau operasi tertentu; g) mengaplikasikan konsep atau algoritma pada pemecahan masalah. Indikator pemahaman konsep dapat memaksimalkan aktivitas peserta didik. Serta indikator pemahaman konsep memotivasi peserta didik dalam belajar. Hal ini dibuktikan dengan skor efektifitas 4,30 dalam kategori sangat efektif dengan rincian aktivitas peserta didik dalam kategori sangat baik dengan skor rata-rata 4,52, respon peserta didik dalam kategori sangat baik dengan skor rata-rata 4,39 hasil belajar peserta didik kelas VIII.B SMP Negeri 2 kota bengkulu sangat baik berdasarkan penilaian LKPD dan tes hasil belajar dengan skor rata-rata 4,05 dan telah mencapai persentase ketuntasan klasikal yaitu 88,88%. Kata kunci : Efektifitas, Discovery Learning, Lembar Kerja Peserta Didik (LKPD), Pemahaman Konsep, Penelitian Pengembangan.

Abstract

Purpose – Problem-solving is a key component in mathematics education, as emphasized by the NCTM. At SMAN 6 Kota Bengkulu, students’ performance in trigonometry remains low due to weak problem-solving skills and limited engagement. This study investigates the effect of the Problem-Based Learning (PBL) model, supported by mathematical literacy worksheets, on students’ mathematical problem-solving abilities. Methodology – A quasi-experimental design was employed using the Nonequivalent Posttest-Only Control Group Design. The population consisted of all 10th-grade students at SMAN 6 Bengkulu. Two classes were selected: Class XJ as the experimental group, taught using the PBL model with literacy-based worksheets, and Class XI as the control group, taught using a Cooperative Learning model. Data were collected through a mathematical problem-solving test and analyzed using an independent t-test. Findings – Results showed a significant difference in performance, with t<sub>value</sub> = 3.713 > t<sub>critical</sub> = 1.673, indicating that the experimental group outperformed the control group in problem-solving ability. Novelty – This study offers a novel integration of PBL with mathematical literacy worksheets—an underexplored instructional approach in secondary trigonometry education. By combining content-specific literacy materials with a problem-based pedagogy, the study addresses a gap in research focused on enhancing higher-order thinking in mathematics. Significance – The findings provide empirical support for incorporating literacy-based, student-centered strategies in mathematics instruction. The study has implications for curriculum design aimed at improving problem-solving performance in similar educational contexts.

Abstract

Mathematical problem-solving ability is a fundamental competency in mathematics education that must be developed from the primary education level. This study aims to describe the mathematical problem-solving abilities of fifth-grade elementary school students in Bengkulu City. The research instruments included a mathematics problem-solving test based on number material and interview guidelines. The results of the study showed that most students were in the fair (29.4%) and low (26.5%) categories in their problem-solving abilities (14.7) in the very low category, while for the very high category (8.8%) and high category (20.6%). The main difficulties faced by students were in the planning phase of the solution and the final verification of answers. The differences in student performance between schools indicate the influence of pedagogical and environmental factors. Teacher interviews revealed that the dominant teaching approach was conventional, lacking emphasis on reasoning and higher-order thinking skills. The findings recommend implementing problem-based learning strategies and providing professional development for teachers to design instruction that promotes critical and creative thinking skills.

Abstract

The understanding of analytic geometry is often hindered by its abstract presentation and its disconnection from local contexts familiar to students. Therefore, this study designed a learning trajectory using conic section batik patterns rooted in Bengkulu’s cultural context. This served as a consolidation phase in learning conic sections and geometric transformations. The study used a design research methodology with three phases: preliminary design, teaching experiment, and retrospective analysis. The participants were mathematics education students enrolled in an Analytic Geometry course. The findings showed that the resulting learning trajectory has three interconnected learning pathways: conceptual exploration, validation through practice, and applicative project work. These pathways illustrate a progression of understanding, moving from procedural toward relational, representational, and applicative thinking. The conic section batik–based learning approach helped students connect elements and general equations of conic sections with visual representations using GeoGebra. It allowed them to apply these concepts in contextual batik designs.
