DEVELOPMENT OF LKPD ON MOLECULAR SHAPE MATERIAL BASED ON INTEGRATED PJBL ETHNOSCIENCE IN SMA

Abstract

evelopment research (R&D) Student Worksheets (LKPD) has been carried out on molecular shape material based on integrated ethnoscience Project Based Learning (PjBL) which aims to determine the validity and practicality of an LKPD using a 4-D model which consists of four stages, namely define , design, develop and disseminate. This development stage is only carried out up to the devolop stage. The instrument used in this study was a validation questionnaire consisting of content and construct validations by five validators. practicality is carried out by chemistry teachers and class XI students of SMAN 2 Pariaman Practicality results data are analyzed using the aikens'V formula and the value analysis obtained is analyzed using the formula for comparing students' scores with students' maximum scores on scoring. The results of the analysis obtained a value of 0.84 which is categorized as valid. While the results of the practicality of teachers and students obtained NP values of 0.86 and 0.92 which were categorized as very practical.
