Abstract

Artikel ini bertujuan untuk mendeskripsikan proses koneksi matematis secara prosedural ditinjau dari asimilasi dan akomodasi pada materi perbandingan. Jenis penelitian ini menggunakan pendekatan kualitatif. Subjek penelitian ini adalah siswa kelas VII SMP Negeri 1 Trucuk yang berjumlah 20 siswa, kemudian terpilih 6 siswa sebagai subjek penelitian yaitu 2 subjek terkategori asimilasi, 2 subjek terkategori akomodasi, dan 2 subjek terkategori asimilasi-akomodasi. Instrumen penelitian terdiri dari soal tes dan wawancara. Untuk keabsahan data digunakan triangulasi metode dan triangulasi sumber. Analisis data menggunakan model Miles dan Huberman dengan tahapan reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa proses koneksi matematis secara prosedural pada subjek yang mempunyai kecenderungan asimilasi melalui tahapan dapat menggunakan pengetahuan sebelumnya untuk memecahkan masalah. Selanjutnya, proses koneksi matematis secara prosedural pada subjek yang mempunyai kecenderungan akomodasi melalui tahapan dapat memodifikasi sendiri dalam memecahkan masalah. Namun, subjek akomodasi akan mengalami hambatan jika tidak dapat melakukan penyesuaian sehingga hasil pekerjaannya tidak tepat. Selain itu, ada juga proses koneksi matematis secara prosedural pada subjek yang mempunyai kecenderungan menggunakan gabungan antara asimilasi dan akomodasi melalui tahapan dapat menyesuiakan pengetahuan yang dimiliki sebelumnya serta dapat melakukan modifikasi untuk mempermudah dalam memecahkan masalah.

Abstract

The purpose of this study was to describe the assimilation-accommodation process on a proportion topic. The descriptive qualitative approach was utilized to elucidate the assimilation-accommodation process. Data collection was accomplished using assessments administered to 13 students online and 7 students offline. The participants were chosen from a pool of twenty students based on their classification of procedural predictions of mathematical connection indicators. Six research subjects were selected from seven students who satisfied the expected indications of assimilation, accommodation, and assimilation-accommodation, with each category two students having the identical work. Additionally, data are gathered through tests and interviews that have been triangulated for source and method validity. The findings indicated the first two subjects demonstrate the assimilation process through the phases of proportion concept knowledge taught in primary school. This is shown by how the problem is solved, which begins with formulating the symbolic form proportion formula in variables. In proportion, the following two subjects demonstrate the accommodation process by converting their knowledge into different types of formula produced by assimilation groups, which is in the form of numbers. This is shown by how the problem is solved by immediately writing the answer into the proportion form without using another variable symbol. Meanwhile, the accommodation-assimilation process indicate a proclivity for modifying prior information by dividing proportion formula into different solution procedures from the assimilation and accommodation groups, i.e., in mixed form (some symbols and some numbers). The findings of this study indicate that the assimilation-accommodation process can aid in the acceleration of problem solutions in new materials.
