Abstract

This study aims to produce worksheets using an ethnomatematic based CTL approach on SLETV material that is valid and practical. This type of research and development is R&D. The ADDIE development model consists of: analyze, design, development, implementation, evaluation. However, this research is limited to the implementation stage for individual trials (one to one) and small group trials. The results of this study were obtained from the aspects of validity and practicality. a) the validity aspect is obtained based on 3 validators with assessment aspects based on content, construct, and language with the first validator score of 84.61% in the "valid" category then the second validator is 92.30% with the very valid category and the third validator is 86.53 % with a valid category. b) the practicality aspect is obtained based on 9 student response questionnaires given in the small group trial stage completed with an average score of 83.79% and categorized as "practical".Penelitian ini bertujuan untuk menghasilkan produk LKS Menggunakan Pendekatan CTL berbasis etnomatematika pada materi SLETV yang valid dan praktis. Jenis penelitian dan pengembangan ini adalah R&D. Model pengembangan ADDIE terdiri dari: analyze, design, development, implementation, evaluation.Namun pada penelitian ini dibatasi pada tahap implementasi untuk uji coba perorangan (one to one) dan uji coba kelompok kecil (small group). Hasil penelitian ini di peroleh dari aspek kevalidan dan kepraktisan. a) aspek kevalidan diperoleh berdasarkan 3 validator dengan aspek penilaian berdasarkan isi, konstruk, dan bahasa dengan skor validator pertama yaitu 84,61% dengan kategori “valid” kemudian validator kedua 92,30% dengan kategori sangat valid dan validator ketiga yaitu 86,53% dengan kategori valid. b) aspek kepraktisan diperoleh berdasarkan 9 angket respon siswa yang diberikan pada tahap uji coba kelompok kecil selesai dengan skor rata-rata 83,79% dan dikategorikan “praktis”.

Abstract

The purpose of this study is to create an E-Module based on conceptual understanding of linear programming that is valid, practical, and understands the potential effects of E-Modules. The Research and Development (RD) method was used in this study. This study employs the ADDIE model development procedure, which consists of five stages: analysis, design, development, implementation, and evaluation. The E-Module is declared "valid" based on the assessments given by three validators with four aspects assessed, namely content feasibility, presentation feasibility, language feasibility, and graphic feasibility, with a total percentage of 79.8 percent. The E-Module was regarded "highly practical" based on the results of student response surveys in the small and large groups, which received 83.8 percent and 81.5 percent, respectively. Based on the findings of the teacher response questionnaire, the E-Module was declared "highly practical" with a score of 92 percent. Based on the student learning outcomes test, the e-module is determined to have a "good" potential effect with a score of 66.7 percent.Penelitian ini bertujuan untuk menghasilkan E-Modul berbasis pemahaman konsep pada materi program linear yang valid, praktis dan mengetahui efek potensial E-Modul. Jenis penelitian ini adalah penelitian Research and Development (RD). Penelitian ini mengggunakan prosedur pengembangan model ADDIE yang terdiri dari lima tahapan yaitu Analysis, Design, Development, Implementation, dan Evaluation. Hasil dari penelitian ini adalah E-Modul dinyatakan “valid” berdasarkan penilaian yang diberikan oleh tiga validator dengan empat aspek yang dinilai yaitu kelayakan isi, kelayakan penyajian, kelayakan bahasa, dan kelayakan kegrafisan dengan jumlah persentase sebesar 79,8%. E-Modul dinyatakan “sangat praktis” berdasarkan hasil angket respon peserta didik pada kelompok kecil (Small Group) dan kelompok besar yang masing-masing mendapat persentase sebesar 83,8% dan 81,5%. Serta E-Modul dinyatakan “sangat praktis” berdasarkan hasil angket respon guru dengan persentase sebesar 92%.  E-modul dinyatakan memiliki efek potensial “baik” berdasarkan tes hasil belajar peserta didik yang dengan persentase sebesar 66,7%.

Abstract

Selecta capita of mathematics is a subject that discusses algebra, geometry, and high school calculus material. Students face obstacles during the learning process: misconceptions about studying selecta capita of mathematics and the lack of electronic textbooks. Therefore, it is necessary to have electronic textbooks that can help students to solve problems by prioritizing independence in the learning process. This study aims to produce a selecta capita of mathematics e-books for SHS on a reasonable and practical contextual teaching and learning (CTL) approach and to see the effectiveness of the e-book that has been developed. The development of selecta capita of mathematics e-book for SHS on CTL approach refers to ADDIE development model. The instruments used to determine the quality of a developed e-book are (1) questionnaires to measure the validity, (2) student response questionnaires to measure practicality, and (3) learning outcomes test questions. The results showed that selecta capita of mathematics e-books for SHS based on the CTL approach developed was good quality and could be used in learning.Kapita selekta matematika merupakan mata kuliah yang membahas materi aljabar, geometri dan kalkulus sekolah menengah atas. Salah satu kendala yang dihadapi peserta didik selama proses pembelajaran yaitu terdapat miskonsepsi dalam mempelajari kapita selekta matematika serta masih minimnya buku ajar elektronik. Oleh karena itu, diperlukan adanya bahan ajar elektronik yang dapat membantu peserta didik memecahkan permasalahan dengan mengutamakan kemandirian dalam proses pembelajaran. Penelitian ini bertujuan untuk menghasilkan e-book kapita selekta matematika SMA berbasis pendekatan contextual teaching and learning (CTL) yang valid dan praktis, serta melihat keefektifan e-book yang telah dikembangkan. Pengembangan e-book kapita selekta matematika SMA berbasis pendekatan CTL mengacu pada model pengembangan ADDIE. Instrumen yang digunakan untuk mengetahui kualitas e-book yang dikembangkan, yakni: (1) angket untuk mengukur kevalidan; (2) angket respon peserta didik untuk mengukur kepraktisan; (3) soal tes hasil belajar. Hasil penelitian menunjukkan e-book kapita selekta matematika SMA berbasis pendekatan CTL yang telah dikembangkan berkualitas baik dan dapat digunakan dalam pembelajaran.
