Development of Student Woorksheet Base on STEAM-PjBL Integrated on Reaction Rate Material for Senior high School Class XI

Abstract

ABSTRACT

This development research has produced teaching materials in the form of student worksheets (LKPD) integrated with STEAM-PjBL ( Science, Technology, Engineering, Art and Mathematics - Project Based Learning ) on the subject of Reaction Rate. The results of developing teaching materials that have been designed are tested for validity and practicality to fulfill the requirements of a LKPD. This LKPD development research uses the R&D ( Research and Development ) method namely research and development, with the 4- D model. This 4- D model has stages consisting of (1) define, (2) design, (3) develop and (4) disseminate stages. This development stage is only carried out until the develop stage. In this study using an instrument in the form of a validation questionnaire consisting of a content and construct validation questionnaire and a practicality questionnaire. Validation was carried out by validators, which came from 3 chemistry lecturers at FMIPA UNP and 2 high school chemistry teachers. Practicality testing was carried out by 2 high school chemistry teachers and class XI students from SMAN 13 Padang. Testing this LKPD will produce data that will be analyzed using the Aiken's V formula. Based on the results of the analysis it can be summarized that the resulting LKPD is a teaching material product that is categorized as valid based on a V value of 0.86.
