Uji Validitas Pengembangan Lembar Kerja Peserta Didik (LKPD) Berbasis Keterampilan Proses Sains untuk SMAN pada Konsep Sistem Ekskresi
Daftar Isi:
- This study aims to produce a student worksheet (LKPD) based on science process skills on biology subjects a valid excretory system concept. This type of research and development. The development model used is a four-D model consisting of four stage, namely: (1) Define, (2) Design, (3) Development, (4) Disseminate. This article is limited to the development secion, especially the validity test. Validity test data obtained from the results of validation. To test the validity of LKPD instrument sheets are used, the instrument used is the LKPD validation instrument and data collected from the results of the LKPD validation. LKPD validation is based on three aspects, namely: (1) aspect of LKPD presentation, (2) aspect of content eligibility, (3) aspect of language. The results of the validator assessment for LKPD based on science process skills that was assessed from the aspect of presentation of the LKPD obtained an average 4,40 which is in the valid category, and aspect of content eligibility get an average 4,40 which is in the valid category, and aspect of language get n average 4,25 which is in the valid category. Of the tree aspect LKPD assessment, it is obtained that the average 0f 4,35 is in the valid category. Validation results show that LKPD based on science process skills developed is valid and feasible to use.
