Abstract


Abstract: This study aims to produce teaching materials in the form of e modules based on a contextual approach with a REACT (Relating, Experiencing, Applying, Collaborating, Transferring) strategy on acid-base materials.This development is a type of EDR (Educational Design Research) research with a plomp research model. Lecturers and teachers act as expert reviews, and 9 students become research subjects in this development research. The data obtained in the form of content validity, construct, linguistic and graphic data were processed using the AIken's V formula, while the practicality data was processed using practical percent. Based on the results of the study, the V value for content validity was 0.84, construct validity was 0.83, linguistic validity was 0.84 and graphic validity was 0.87, which were included in the valid category. Then the practicality results show a value of 90 percent with a very practical category and the results of the effectiveness test show that e modules can improve student learning outcomes

Keywords: e modul, contextual approach, REACT learning strategy, acid base

 

Abstrak: Penelitian ini bertujuan untuk menghasilkan bahan ajar berupa e-modul berbasis pendekatan kontekstual dengan strategi REACT (Relating, Experiencing, Applying, Collaborating, Transferring) pada materi asam basa. Pengembangan ini merupakan jenis penelitian EDR (Educational Design Research) dengan model penelitian plomp. Dosen dan guru sebagai expert review, dan 9 mahasiswa menjadi subjek penelitian dalam penelitian pengembangan ini. Data yang diperoleh berupa data validitas isi, konstruk, kebahasaan dan kegrafisan diolah menggunakan rumus aiken's V, sedangkan data kepraktisan diolah dengan persen praktis. Berdasarkan hasil penelitian diperoleh nilai V untuk validitas isi 0,84 validitas konstruk 0,83 validitas kebahasaan 0,84 dan validtas kegrafisan 0,87 yang termasuk dalam kategori valid. Kemudian hasil praktikalitas menunjukkan nilai sebesar 90 persen dengan kategori sangat praktis dan hasil uji efektivitas menunjukkan bahwa e-modul dapat meningkatkan hasil belajar siswa. Sehingga dapat disimpulkan bahwa e-modul yang dikembangkan sudah valid dan praktis sehingga layak digunakan dalam pembelajaran

Kata kunci: e modul, pendekatan konstekstual, strategi REACT, asam basa.
