THE DEVELOPMENT OF BILLINGUAL INTERACTIVE E-BOOK WITH CONTEXTUAL TEACHING AND LEARNING ORIENTED ON ELECTROLYSIS SUB TOPIC

Abstract

Tujuan penelitian ini adalah untuk mengetahui kelayakan E-book berdasarkan penilaian guru yang meliputi kelayakan kesesuaian dengan komponen CTL, materi, penyajian ilustrasi, dan bahasa. Metode penelitian ini menggunakan metode Research & Development (R&D) dan pada tahap pengembangan menggunakan 4D (define, design, develop, disseminate) namun hanya terbatas pada tahap develop. Instrumen yang digunakan adalah lembar telaah dan lembar validasi. Telaah dilakukan oleh 3 orang dosen kimia dan 1 guru kimia. Validasi dari 3 guru kimia terhadap E-book yang dikembangkan memperoleh presentase 81,58% termasuk kategori sangat layak.

Kata Kunci: E-book, CTL, kelayakan, Elektrolisis.

The aim of this research to know feasibility of E-book development based on teacher assessment that consist of CTL component, content, layout, and language suitability. This research uses Research & Development (R&D) method and on development step uses 4D models (define, design, develop, disseminate) but it is limited in develop step. Instruments that are used review and validity sheet. Review has been done by three chemistry lecturers and one chemistry teacher. Validity from three chemistry teachers shows that the E-book that was prepared reach 81,58%, included very good (very feasible) category.

Key words: E-book, CTL, feasibility, Electrolysis
