Abstract

The mathematics teaching materials used by teachers today are still printed teaching materials provided by the government. As a result, it is ineffective to improve students' learning outcomes because they seem discouraged and bored while learning. Thus, it is important to design teaching materials that utilize technological developments so that they are easily accessible to students to learn mathematics anytime and anywhere. This study aims to design a valid E-Module with an Open Ended approach based on Gambyong Dance Ethnomathematics on grade VIII SPLDV material. This research uses the Research and Development (R&D) research methodology with the ADDIE development model which is limited to the analysis, design and development stages. The data analysis techniques used include needs analysis, media expert validation analysis and material experts. This study produced an E-Module design along with the results of E-Module validation from media experts with an average assessment of 3.5 which is classified as a valid category and material experts with an average assessment of 3.6 which is classified as a valid category. The average combined E-Module assessment from media experts and material experts obtained a score of 3.54 in the valid category. This shows that the E-Module design is feasible to be tested on students during math learning.

Abstract

Berpikir komputasioal adalah kemampuan untuk memecahkan masalah melalui prinsip komputasi yang penting dikuasai mahasiswa. Salah satu masalah matematika yang sering kali menuntut mahasiswa untuk berpikir secara komputasional adalah masalah-masalah yang berkaitan dengan program linear dalam mencari solusi optimal permasalahan yang memiliki kendala-kendala tertentu. Beberapa metode penyelesaian masalah program linear antara lain metode simpleks, metode dualitas, dan metode pemrograman dinamis. Metode simpleks menggunakan konsep iterasi dan pertukaran variabel untuk menemukan solusi optimum. Tujuan dari penelitian ini adalah untuk mendeskripsikan kemampuan berpikir komputasional mahasiswa dalam mengaplikasikan metode simpleks pada penyelesaian masalah program linear. Metode penelitian ini menggunaka deskriptif dengan pendekatan kualitatif. Subjek yang dilibatkan adalah 16 mahasiswa semester III Program Studi Pendidikan Matematika.  Teknik analisis dilakukan melalui tahapan antara lain reduksi data, penyajian data, dan pengambilan kesimpulan. Hasil penelitian ini menunjukkan mahasiswa dalam melakukan penyelesaian masalah matematika hanya dapat memenuhi indikator dekomposisi dan pengenalan pola. Artinya mahasiswa memiliki kemampuan yang terbatas pada tahap penyederhanaan masalah dan menyusun strategi penyelesaian. Shingga pencapaian indikator tersebut menjadi dasar bahwa mahasiswa memiliki kemampuan berpikir komputasional yang rendah.
