PENGEMBANGAN MODUL BERBASIS CONTEXTUAL TEACHING AND LEARNING (CTL) MELALUI METODE EKSPERIMEN PADA POKOK BAHASAN KOLOID

Abstract: Development of Contextual Teaching and Learning (CTL) Based Modules Through Experimental Methods on Colloidal Subjects. This study aims to (1) determine the level validation learning modules colloidal materials developed based CTL, (2) student responses CTL-based through experimental methods materials, (3) outcomes modules. materials. uses method (R&D) with Dick Carey model at each stage (planning development, validation, revision (modification), product testing).
