Abstract

The purpose of this research is to produce a Hypothetical Learning Trajectory for geometric transformation material on the topic of rotation using the context of batik motifs and the Ferris wheel game. The research method used is design research. The learning approach used is Realistic Mathematics Education Indonesia (RME). Hypothetical Learning Trajectory (HLT) was developed from learning activities using the context of batik motifs and the Ferris wheel game. The research subjects were three students of class IX SMPN 7 Bukittinggi. Theoretical development was carried out through designing learning activities with HLT design at the preliminary stage, carrying out one to one activities in teaching experiments and retrospective analysis. Data was collected by observation, interviews, and documentation. After the observations were made, the results of the LKPD work were collected which were given to students, interviewed students. The results obtained from the interview process, students can use the HLT design that was developed because it has a systematic guide sequence to teach the topic of geometric transformation about rotation in the one to one implementation. what is predicted and what is anticipated. So the results of the HLT design for geometric transformation materials on the topic of rotation using the context of batik motifs and the Ferris wheel game are obtained.Tujuan penelitian menghasilkan Hypothetical Learning Trajectory materi transformasi geometri pada topik rotasi menggunakan konteks motif batik dan permainan bianglala. Metode penelitian yang digunakan adalah design research Pendekatan pembelajaran yang digunakan adalah Realisticcs Mathematics Education Indonesia (RME). Hypothetical Learning Trajectory (HLT) dikembangkan dari aktivitas pembelajaran menggunakan konteks motif batik dan permainan bianglala. Subjek penelitian adalah tiga peserta didik kelas IX SMPN 7 Bukittinggi, Pengembangan secara teoritis dilaksanakan melalui perancangan aktivitas pembelajaran dengan desain HLT pada tahap preliminary, melaksanakan kegiatan one to one pada teaching experiment dan restrospective analysis. Pengumpulan data dilakukan dengan observasi, wawancara, dan dokumentasi. Setelah observasi dilakukan maka dikumpulkan hasil pengerjaan LKPD yang diberikan pada peserta didik, mewawancarai peserta didik. Hasil penelitian diperoleh proses wawancara, peserta didik dapat menggunakan desain HLT yang dikembangkan karena memiliki urutan panduan yang sistematis untuk mengajarkan topik transformasi geometri tentang Rotasi pada  pelaksanaan one to one menunjukkan bahwa penggunaan konteks motif batik dan permainan bianglala pada desain HLT transformasi geometri tentang Rotasi sesuai antara apa yang diprediksi dan antipasi yang dilakukan. Jadi  diperoleh hasil rancangan HLT materi transformasi geometri pada topik rotasi menggunakan konteks motif batik dan permainan bianglala.

Abstract

Kemampuan pemecahan masalah sangat penting untuk menghasilkan ide dan strategi untuk mengonstruksi pengetahuan. Faktanya, kemampuan pemecahan masalah matematika peserta didik masih kurang akibat kurangnya perangkat pembelajaran dan keterlibaatan belajar yang tidak memadai. Penelitian ini memiliki tujuan untuk mengembangkan modul ajar dan E-LKPD berbasis Creative Problem Solving untuk meningkatkan kemampuan pemecahan masalah matematis peserta didik kelas X SMA. Penelitian pengembangan ini dilakukan dengan mengikuti tiga tahapan model Plomp yang meliputi fase investigasi awal, pengembangan, dan penilaian. Investigasi awal mencakup analisis kebutuhan, kurikulum, konsep, karakteristik peserta didik, dan studi literatur. Fase pengembangan mencakup perancangan modul ajar dan E-LKPD berbasis CPS, diikuti evaluasi formatif melalui self evaluation, expert review, one to one evaluation, dan small group evaluation. Fase penilaian melibatkan field test dan analisis soal tes kemampuan pemecahan masalah. Data dikumpulkan melalui lembar validasi, pedoman wawancara, angket, daftar ceklis, dan soal tes kemampuan pemecahan masalah. Hasil penelitian menunjukkan modul ajar berbantuan E-LKPD berbasis CPS memenuhi kriteria “sangat valid” dengan nilai validitas sebesar 3,51 untuk modul ajar dan 3,50 untuk E-LKPD pada aspek kelayakan isi, penyajian, kegrafikan, dan bahasa. Praktikalitasnya dikategorikan “sangat praktis” dengan nilai praktikalitasnya 91,67% (modul ajar) dan 85,59% serta 86,28% (E-LKPD). Efektivitasnya terlihat dari peningkatan kemampuan pemecahan masalah dengan persentase peserta didik yang tuntas adalah 71,88%. Disimpulkan bahwa modul ajar dan E-LKPD berbasis CPS pada materi perbandingan trigonometri valid, praktis, dan efektif dalam meningkatkan kemampuan pemecahan masalah matematis peserta didik.Problem-solving ability plays a crucial role in developing ideas and strategies to construct knowledge. However, students’ mathematical problem-solving skills remain low due to limited active learning and the absence of learning tools specifically designed to support this skill development. This study aims to develop a teaching module and an electronic student worksheet (E-LKPD) based on Creative Problem Solving (CPS) to improve the mathematical problem-solving ability of tenth-grade high school students.The research follows the Plomp development model with three phases: preliminary investigation, development, and assessment. The preliminary investigation includes needs analysis, curriculum study, concept review, student characteristics analysis, and literature review. The development phase involves designing the teaching module and CPS-based E-LKPD, followed by formative evaluations through self-evaluation, expert review, one-on-one evaluation, and small group evaluation. The assessment phase consists of field testing and analyzing problem-solving test results.Data were collected via validation sheets, interview guides, questionnaires, checklists, and problem-solving tests. The results show the CPS-based teaching module and E-LKPD are “very valid,” with validity scores of 3.51 for the module and 3.50 for the E-LKPD, covering content feasibility, presentation, graphics, and language. Practicality is rated “very practical,” with scores of 91.67% for the module and 85.59% and 86.28% for the E-LKPD. Effectiveness is indicated by an increase in problem-solving skills, with 71.88% of students achieving mastery. In conclusion, the CPS-based teaching module and E-LKPD on trigonometric ratios are valid, practical, and effective in improving students’ mathematical problem-solving abilities.

Abstract

The development of digital technology has shifted the learning paradigm towards a more interactive and collaborative approach. This study aims to evaluate the effectiveness of the Team Games Tournament (TGT) learning model combined with Baamboozle media in improving the quality of the process and student learning outcomes. The research method used was a Systematic Literature Review (SLR) and bibliometric analysis of articles retrieved from Google Scholar in the 2020–2025 period. From the search results, 10 publications relevant to the research topic were obtained. The results of the study indicate that the implementation of the TGT model assisted by Baamboozle can improve students' learning outcomes, motivation, active participation, teamwork, and critical thinking skills. In addition, the bibliometric analysis shows that dominant keywords such as "team games tournament", "Baamboozle", and "cooperative learning" reflect the increasing research trend on the integration of cooperative models with interactive digital media. Thus, the integration of TGT and Baamboozle can be an effective pedagogical strategy to create fun, collaborative, and relevant learning to meet the needs of education in the digital era.
