Development of STEAM - PjBL Integrated LKPD on Basic Laws of Chemistry Phase E High School

Abstract

This This research aims to produce teaching materials in the form of STEAM-PjBL integrated LKPD on Basic Chemical Law material that is valid and practical. This research is development research or Research and Development (R & D) and 4-D is the development model. The 4-D model consists of four stages, namely define, design, develop and disseminate. Due to lack of time, this research was only limited to the development stage, namely testing validity and practicality. The instruments used in this research were validation sheets and practicality sheets. The validity test was carried out by 5 validators and the practicality test was carried out by 2 teachers and 10 Phase E students at SMA N 15 Padang. Validity test will be analyzed using the Aiken's v scale formula. Data analysis obtained an average validity of 0.88 with a valid category. Based on the practicality test of teachers and students, respectively, percentages of 93.16% and 91% were obtained in the very practical category. It can be concluded that the STEAM – PjBL integrated LKPD on basic chemistry legal material is valid and practical.
