Toward learning trajectory‐based instruction: A framework of conceptions of learning and assessment

This research aims to produce a Learning Trajectory Based Instruction (LTBI) that can help the ninth grade students understand the concept of congruence of the two-dimensional shape by examining Lawang Sewu as one of Central Java historical buildings. LTBI is defined as a teaching and learning trajectory that uses Hypothetical Learning Trajectory (HLT) for instructional decisions. The present research uses the design research developed by Gravemeijer and Cobb that consists of three phases; the preliminary design, design of the experiment (pilot experiment and teaching experiment), and retrospective analysis. In this study, a series of learning activities is designed and developed based on the Realistic Mathematics Education (PMRI) approach. This research produced LTBI that consists of a series of learning processes embodied in three activities of (1) identifying and finding the properties which shapes are congruent shapes by watching Lawang Sewu video, (2) proofing two shapes are congruent through transformation (translation and rotation), and (3) solving problem related to the congruence of two-dimensional shape. The activity can help to improve the students’ understanding of the concept of congruence. Nevertheless, the present study is limited to the first stage of Gravemeijer and Cobb’s design research, namely preliminary design.

AbstrakSebagian besar siswa masih mengalami kesulitan dalam belajar kerucut. Oleh karena itu diperlukan pendesainan lintasan belajar materi tersebut menggunakan konteks dan media yang tepat. Penelitian ini bertujuan untuk menghasilkan Learning Trajectory Based Instruction (LTBI) materi kerucut menggunakan konteks tradisi Syawalan masyarakat Pekalongan yaitu Megono Gunungan yang dikemas dalam bentuk video interaktif. Penelitian ini menggunakan design research yang dikembangkan oleh Gravemeijer dan Cobb yang terdiri dari tiga tahap yaitu: preliminary design, design of the experiment (pilot experiment and teaching experiment), dan retrospective analysis. Namun, artikel ini memaparkan hasil pada tahap pertama, yaitu tahap preliminary design. Subjek penelitian ini adalah siswa kelas IX SMP N 38 Semarang. Dalam penelitian ini dihasilkan LTBI yang terdiri dari serangkaian aktivitas pembelajaran, yaitu: (1) mengidentifikasi bagian-bagian kerucut melalui video interaktif Megono Gunungan, (2) menemukan luas permukaan kerucut dengan menggunakan jaring-jaring kerucut, (3) menemukan volume kerucut dengan menggunakan media beras, dan (4) menyelesaikan masalah kontekstual yang berkaitan dengan kerucut. Selanjutnya, siswa diharapkan dapat lebih mudah memahami materi kerucut melalui beberapa aktivitas yang telah didesain. Development of Learning Based on Trajectory Material Cone Middle School Using Megono Gunungan AbstractMost students still experience difficulties in learning cones. Therefore it is necessary to design the learning trajectory of the material using the right context and media. This study aims to produce Learning Trajectory Based Instruction (LTBI) cone material using the context of the Pekalongan community's Syawalan tradition, Megono Gunungan, which is packaged in the form of interactive video. This study uses design research developed by Gravemeijer and Cobb which consists of three stages: preliminary design, design of the experiment (pilot experiment and teaching experiment), and retrospective analysis. However, this article presents the results of the first stage, the preliminary design stage. The subjects of this study were students of class IX SMP N 38 Semarang. In this study LTBI produced consisting of a series of learning activities, namely: (1) identifying cone sections through interactive video Megono Gunungan, (2) finding the surface area of the cone by using cone nets, (3) finding the volume of the cone by using rice media, and (4) resolve contextual problems related to cones. Furthermore, students are expected to more easily understand the cone material through several activities that have been designed.
