Penelitian ini bertujuan untuk merancang langkah-langkah pembelajaran mengenai luas permukaan balok berdasarkan PBL dan mendeskripsikan kemampuan siswa dalam memahami konsep matematika tentang luas permukaan balok setelah mengalami pembelajaran dengan pendekatan PBL. Penelitian ini dilaksanakan di SMPN 1 Ende tahun 2020. Desain pembelajaran diperoleh dengan mengembangkan Hypothetical Learning Trajectory (HLT), yang membantu siswa mengembangkan konsep luas permukaan balok berdasarkan pendekatan PBL. Pengumpulan data dilakukan dengan menggunakan tes tertulis, dan wawancara. Analisis data meliputi reduksi data, penyajian data, verifikasi atau penarikan kesimpulan. Hasil penelitian menunjukkan bahwa (1) langkah-langkah pembelajaran pada materi luas permukaan balok dengan menggunakan pendekatan PBL yaitu (a) mengorientasikan, (b) mengorganisasikan peserta didik, (c) membimbing penelitian secara individu atau kelompok, (d) mengembangkan dan mempresentasikan hasilnya, (e) menganalisis dan mengevaluasi. (2) Terdapat kemampuan pemahaman konsep siswa kelas VIII setelah mengikuti pembelajaran berbasis pendekatan PBL, yaitu (a) untuk soal nomor 1 terdapat 14 siswa yang dapat mencapai indikator 1 sampai 4 dalam pemahaman konsep, dan ( b) untuk soal nomor 2, ada 11 dari 14 siswa yang dapat mencapai indikator 1 sampai 4 dalam pemahaman konsep, 3 dari 14 siswa tidak dapat mencapai indikator 3 dan 4 dalam pemahaman konsep.

This study aims to explore the students’ mathematical understanding in integer division operation through the context of archipelago traditional cakes in class VII. This research is related to the Indonesian Realistic Mathematics Approach (PMRI) as a learning approach used. The methodology used in this study is Design Research consisting of three stages: preliminary design, experimental design, and retrospective analysis. The study was conducted on VII grade students of Palembang 1 Junior High School. The learning path (Hypothetical Learning Trajectory) in design research plays an important role as a research design and instrument. The Hypothetical Learning Trajectory (HLT) was developed together with a series of activities using the context of archipelago traditional cakes such as: omelette roll, bakpia, milk pie, etc. The medium used in this study was the Students’ Activity Sheet. The results of this study indicate that exploration using the context of traditional archipelago cakes can help students understanding in multiplication and division of integers. The conclusion of this study is the use of archipelago traditional cakes as starting point in mathematics learning in integer division operation material helps the students to explore their understanding in solving mathematics problems.

After launching an online Computer Science post-baccalaureate degree program, this study was undertaken to inform the redesign of an introductory Computer Science course using a student-centered, problem-based learning approach. The research team proposed a weekly/unit learning trajectory as they were engaged in student-centered, problem-based learning. Over a timeframe of three university terms, the research team used a design-based, iterative examination to refine the implementation of various instructional actions in the learning trajectory. Multiple small groups of students discussed their learning experiences each term, providing directions for improvements. The analysis directed successive iterations, refining the content, problem solving, and collaborations in the class. This research method assured authentic student voice in an iterative redesign of the course.
