Abstract

Penelitian ini adalah penelitian deskriptif kualitatif untuk menganalisis kesalahan pemahaman konsep peserta didik dalam menyelesaikan soal-soal integral lipat dua pada koordinat polar. Tiga puluh peserta didik yang mengambil mata kuliah kalkulus peubah banyak menjadi subjek dalam penelitian ini. Data dikumpulkan dengan menggunakan tes dan dokumentasi. Hasil jawaban tes peserta didik serta dokumentasi hasil pengerjaan peserta didik, dikoreksi, dianalisis berdasarkan indikator pemahaman konsep dan didisplay data. Analisis kesalahan jawaban peserta didik berdasarkan indikator pemahaman konsep yakni (1) menyatakan ulang konsep integral. (2) merepresentasikan konsep ke bentuk lain, (3) memilih dan menggunakan prosedur serta (4) menggunakan konsep dan algoritma pemecahan masalah. Dalam menyatakan ulang konsep integral peserta didik langsung menggunakan batas atas dan batas bawah integrasi tanpa menuliskan terlebih dahulu hasil pengintegralan. Kesalahan merepresentasikan fungsi ke grafik adalah, fungsi langsung disketsakan tanpa membuat table, memplot titik dan membuat kurva. Kesalahan dalam memilih dan menggunakan prosedur dan penggunaan algoritma pemecahan masalah dikarenakan kurangnya pengetahuan awal peserta didik mengenai materi prasyarat yakni, integral trigonometri dan fungsi trigonometri.

Abstract

Change of thinking starting from the references used to new knowledge that will be taught and learned. In every design or learning process there will definitely be a didactic transposition process. This research is a phenomenological research that explains what didactic transpositions occurred when designing the arithmetic learning vlog script in the Tijarah context which was prepared by one of the students at UIN Raden Fatah Palembang. The data used is in the form of learning resources, results of expert discussions and 4 drafts of arithmetic learning vlog scripts in the Tijarah context. All data is explained and combined into a table that is easier to understand. Data collection took the form of group discussions and also portfolio analysis carried out on learning vlog scripts. From the results of the analysis, it was found that didactic transposition occurred in the preparation of the Arithmetic learning vlog script in the Tijarah context, which was seen from 1) changes in context and the problems raised; 2) the form of constructivist learning and 3) the relationship between learning and the Tijarah context. This shows that in the process of preparing open materials, didactic transposition can occur.
