DEVELOPING DIGITAL WORKSHEET BASED ON ANDROID SUBJECT BIODIVERSITY GASTROPODS IN MANGROVE FOREST AT TUNDA ISLAND BANTEN

Abstract

ABSTRACT This research aimed to develop a digital student’s work sheets used Android based on mangrove forest of Tunda Island gastropod diversity for invertebrate sub concept and to assessed the student’s work sheets based on material, media, and student response aspects.
