Abstract

Abstract The development of STEM-based LKPD (Science, Technology, Engineering and Mathematics) in this study aims to improve students' scientific literacy skills on excretory system material and is distributed through software construct 2 which has the advantage of not using programming languages . (coding) in its design. The research design applied is a research and development type with a 4-D framework model consisting of four stages, namely: 1) Definition, 2) Design, 3) Development (Develop) and 4) Implementation.
