Abstract
Penelitian terdahulu telah mendokumentasikan learning obstacles yang dialami peserta didik SMP dalam mempelajari materi Sistem Persamaan Linear Dua Variabel (SPLDV), yang berakibat pada rendahnya hasil belajar matematika. Tujuan penelitian ini adalah merancang Local Instruction Theory (LIT) melalui Hypothetical Learning Trajectory (HLT) dengan karakteristik matematika bermakna, berbasis konteks, kolaboratif, reflektif, dan rekonstruksi untuk mengembangkan koneksi matematis, representasi matematis, dan intuisi matematis peserta didik. Rancangan LIT dalam penelitian ini yaitu pada materi SPLDV menggunakan pendekatan Realistic Mathematics Education (RME). Metode penelitian yang digunakan yaitu design research yang dilakukan sebanyak dua siklus. Masing-masing siklus dilakukan dalam tiga tahap design research yaitu preliminary design, teaching experiment, dan retrospective analysis. Subjek penelitian ini sebanyak 50 peserta didik dengan masing-masing siklus melibatkan 25 peserta didik. Siklus I dilakukan selama 5 minggu dengan melibatkan peserta didik kelas VIII di SMPN 19 Bandung. Siklus II dilakukan selama 5 minggu dengan melibatkan peserta didik kelas VIII di SMP Salman Al Farisi Bandung. Pembelajaran di kedua siklus dilakukan secara luring di akhir masa pandemi COVID-19. Data yang dikumpulkan dari berbagai sumber yaitu dari hasil tes, lembar kerja peserta didik, lembar observasi guru dan peserta didik, dokumentasi, wawancara, dan rekaman video selama pembelajaran. Hasil penelitian ini mendeskripsikan bagaimana desain LIT SPLDV dalam pola integrasi RME embedded (tertanam) dengan materi utama SPLDV dan materi tertanam persamaan garis dan grafik kartesius, juga simulasi SPLDV secara realistik. LIT pada materi SPLDV menjelaskan langkah-langkah yang dilalui peserta didik pada submateri pengertian SPLDV, penyelesaian SPLDV dengan metode aljabar, penyelesaian SPLDV dengan metode aljabar singkat, penyelesaian SPLDV dengan metode grafik, penyelesaian SPLDV dengan metode gabungan, dan penyelesaian SPLDV dengan metode gabungan dan grafik. Penerapan LIT SPLDV dalam pendekatan RME berkontribusi pada pengembangan setiap indikator dari koneksi dan representasi matematis. Secara keseluruhan, rata-rata siklus I mencapai kategori baik, namun muncul beberapa learning obstacle baru. Hasil pada Siklus II menunjukkan bahwa learning obstacle baru telah berhasil diatasi dan semua learning obstacle telah berhasil diatasi dengan LIT yang telah direvisi. LIT yang dihasilkan berdampak pada pengembangan koneksi, representasi, dan intuisi matematis peserta didik dengan baik. Previous research has documented the learning obstacles experienced by junior high school students in learning the material of Two-Variable Linear Equations System (SPLDV), which results in low mathematics learning outcomes. The purpose of this study is to design a Local Instruction Theory (LIT) through a Hypothetical Learning Trajectory (HLT) with the characteristics of meaningful mathematics, context-based, collaborative, reflective, and reconstruction. to develop mathematical connections, representations, and students' mathematical intuition. The LIT design in this study is on SPLDV material using a Realistic Mathematics Education (RME) approach. The research method used is design research conducted in two cycles. Each cycle was carried out in three stages of design research, namely preliminary design, teaching experiment, and retrospective analysis. The research subjects were 50 students with each cycle involving 25 students. Cycle I was carried out for 5 weeks involving eighth-grade students at SMPN 19 Bandung. Cycle II was carried out for 5 weeks involving eighth-grade students at SMP Salman Al Farisi Bandung. Learning in both cycles was conducted offline at the end of the COVID-19 pandemic. Data were collected from various sources, including test results, student worksheets, teacher and student observation sheets, documentation, interviews, and video recordings during learning. The results of this study describe how the LIT design for SPLDV is integrated with RME embedded pattern with the main SPLDV material and the embedded material of line equations and Cartesian graphs, as well as realistic SPLDV simulations. The LIT for SPLDV material explains the steps taken by students in the subtopics of understanding SPLDV, solving SPLDV with algebraic methods, solving SPLDV with short algebraic methods, solving SPLDV with graphical methods, solving SPLDV with combined methods, and solving SPLDV with combined and graphical methods. The application of LIT for SPLDV using the RME approach contributes to the development of every indicator of mathematical connections and representations. Overall, the average score in Cycle I reached the good category, but some new learning obstacles emerged. The results in Cycle II show that new learning obstacles have been successfully overcome, and all learning obstacles have been successfully addressed with the revised LIT. The resulting LIT has a positive impact on the development of students' mathematical connections, representations, and intuition.
