Pengembangan Lembar Kerja Peserta Didik (LKPD) Berbasis Reading, Mind Mapping And Sharing (RMS) Pada Pokok Bahasan Kesetimbangan Ion Dan Ph Larutan Garam Kelas Xi SMA/MA Sederajat
The development of Student’s Worksheets based on RMS (Reading, Mind Mapping and Sharing) on the material of ion balance and pH of salt solution aims to produce a Student’s Worksheet with valid categories and determine user responses. The development of Student’s Worksheets is carried out with an R&D approach using a 4-D development model, but only carried out until the third stage, namely Develop. The data collection instrument consists of a validation sheet and a user response questionnaire. The analysis technique used is to calculate the percentage score from the validation results and user responses, so that the research results are obtained in the form of percentage values from aspects of content feasibility, RMS characteristics, language, presentation and graphics with scores respectively 95,24%, 93,75%, 95%, 97,22%, and 95,83% with valid category. Valid Student’s Worksheets were then tested one by one to 3 students who had different abilities and responded to the RMS-based Student’s Worksheets, after that a trials was conducted on 3 chemistry teachers who scored 94,79% with very good criteria, and a limited trial by 20 students with a score of 89,875% on very good criteria.
