Pengembangan Lembar Kegiatan Peserta Didik (LKPD) Berbasis Model Pembelajaran Multipel Representasi Pada Pokok Bahasan Laju Reaksi Untuk Kelas XI SMA/MA Sederajat
Development of Student Activity Worksheets (LKPD) Based on Multiple Representation on the subject of reaction rates is the development of teaching materials that prioritizes three levels of chemical representation, namely macroscopic, submicroscopic, and symbolic representations. This research aims to develop LKPD based on multiple representation learning models on the subject of reaction rates for class XI SMA/MA and equivalent that are valid and to determine user responses to LKPD based on multiple representations. The development research method used is (Research and Development, R & D) with a 4-D development model which includes Define, Design, Develop and Disseminate. The object of this research is LKPD based on Multiple Representations on the subject of reaction rates for class XI SMA/MA equivalent. The data collection instruments used were validation sheets and user response questionnaires. The results of the data processed from the validation sheet and user response questionnaires obtained validity results for aspects of the feasibility of content, characteristics of the Multiple Representation model, language, presentation and graphics respectively 95.83%, 97.16%, 95%, 98.33% , and 97.92% with valid criteria. LKPD that has been validly tested on 20 students and 2 high school chemistry teachers each obtained a response of 88.303% and 92.79% with very good criteria.
