Abstract:This study aims at determining the role of the number line media in helping students understand and obtain local instructional theory in learning integer operations in the 4th Grade of Madrasah Ibtidaiyah in Tarakan. This research is design with three stages, namely preliminary design, experimental design, and retrospective analysis. In the preliminary design stage, a number line media along with the hypothetical learning trajectory is made. Then the teaching experiment is conducted to compare the expected learning trajectory with the actual learning trajectory that takes place. In the final stage, a retrospective analysis is carried out by viewing the video recording of learning and evaluation results. From the analysis, it was found that the use of number lines can help students to understand the operations of addition and subtraction of integers. This study also developed local instructional theory related to learning integers using number lines.Abstrak:Penelitian ini bertujuan untuk mengetahui peranan media garis bilangan dalam membantu pemahaman siswa serta mengembangkan teori instruksional lokal (local intructional theory) pada pembelajaran operasi bilangan bulat di kelas IV di salah satu Madrasah Ibtidaiyah di Kota Tarakan. Desain penelitian ini terdiri dari tiga tahap, yaitu desain pendahuluan, desain percobaan, dan analisis retrospektif. Pada tahap desain pendahuluan dilakukan pembuatan media garis bilangan beserta dugaan lintasan belajar, kemudian dilakukan percobaan pengajaran untuk membandingkan lintasan belajar yang diharapkan dengan lintasan belajar yang sesungguhnya terjadi. Pada tahap akhir dilakukan analisis retrospektif dengan melihat rekaman video pembelajaran dan hasil evaluasi. Dari analisis tersebut ditemui bahwa penggunaan garis bilangan dapat membantu siswa untuk memahami operasi penjumlahan dan pengurangan bilangan bulat.

This article presents the results of a 7th-grade classroom teaching experiment that supported students' understanding of integer addition and subtraction. The experiment was conducted to test and revise a hypothetical learning trajectory so as to propose a potential instructional theory for integer addition and subtraction. The instructional sequence, which was based on a financial context, was designed using the Realistic Mathematics Education theory. Additionally, an empty, vertical number line (VNL) is posited as a potentially viable model to support students' organizing their addition and subtraction strategies. Particular emphasis is placed on the mathematical practices that were established in this setting. These practices indicate that students can successfully draw on their experiences with assets, debts, and net worths to create meaning for integer addition and subtraction.
