Application of TPACK Approach in Developing E-LKPD Based on PBL Model of Atomic Structure Material Phase E High School

Abstract

Education in the modern era refers to innovative learning using technology and student-centered learning methods. This research aims to produce teaching materials equipped with technology such as E-LKPD using TPACK and PBL approaches for valid and practical atomic structure materials. This study uses a type of Research and Development (R&D) research with the ADDIE model. The research of the ADDIE model consists of five stages such as; analysis, design, development, implementation and evaluation at each stage. With time and cost limitations, this research is limited to the development stage with validation and practicality tests. The validity test was carried out with five media and material experts while the practicality test was carried out with two chemistry teachers and nine students at SMA N 1 Sitiung. The validity test was processed using Aiken'V theory. The average validity analysis results were obtained at 0.92 with the valid category. The analysis of the results of the practicality test of teachers and students was obtained by 91.4% and 84.6%, respectively, which were categorized as very practical. It can be concluded that E-LKPD uses TPACK and PBL approaches for valid and practical atomic structure materials.
