Abstract

The purpose of this study is to describe students’ commognitive processes when solving contextual problems on definite integrals related to the area between curves. The research method was carried out through several stages, namely preparation, data collection, analysis, and drawing conclusions. The research subjects were ten students from a private university in Indonesia who were asked to solve a contextual mathematics problem within 30 minutes, specifically on definite integrals to determine the area bounded by two curves. Based on their work, one student was selected as the main subject to be analyzed using a commognitive approach and interviewed in depth to obtain more detailed information. The results of the study showed that the subject was able to translate the problem statements into mathematical form accurately. The subject was also able to use mathematical terms and symbols correctly (words use), illustrate the given conditions into graphs appropriately (visual mediators), and apply problem-solving steps systematically based on prior knowledge (routines). In addition, the subject was able to draw correct conclusions supported by valid mathematical arguments. Based on these findings, it can be concluded that students are capable of solving contextual mathematics problems successfully. Furthermore, it is expected that students can improve their understanding of course materials so that they are able to solve given problems more optimally and support the achievement of learning objectives.

Abstract

Latar Belakang: Pembelajaran online dengan  menggunakan e-book/ buku digital merupakan media pembelajaran digital yang dapat diakses  kapanpun dan dimanapun. Pembelajaran ini dirancang interaktif untuk mepermudah pemahaman siswa. Dalam memudahkan pembuatan e-book, maka dirancanglah Sigil yang bersifat open source dan menggunakan format EPUB[7]–[9].  Serangkaian fitur canggih dapat mengemas dan memformat e-book melalui sigil dan dapat berjalan pada multiplatform baik Windows, Linux, maupun Mac; serta mendukung impor file EPUB dan HTML, sheets, dan gambar. Tujuan: untuk memberikan pelatihan pembuatan e-book dengan Sigil kepada guru-guru SDI An-Nur Surabaya. Metode: pelatihan penyusunan e-Book dengan Sigil, dengan  format  kegiatan  pemaparan  materi dan  praktik  terbimbing, serta produk  yang dihasilkan oleh peserta berupa e-Book sesuai dengan mata pelajaran yang diampu    oleh    guru. Hasil: guru dapat Menyusun e-Book sesuai dengan tingkat pemahaman siswa. Kesimpulan:  dengan pelatihan yang diberikan, diharap guru dapat menyusun e-book dengan baik.
