Validitas dan Praktikalitas E-Modul Berbasis Inkuiri Terbimbing Terintegrasi Laboratorium Virtual pada Materi Hidrolisis Garam kelas XI SMA/MA

This study aims to produce a salt hydrolysis e-module which is based on guided inquiry learning model and integrated with virtual laboratories and reveal the validity and practicality of e-modules. The type of this research is Reasearch and Development (R&D), the method used in this research is development model by using 4-D design. They are define, design, develop and disseminate. This research was limited to the stage of development, the validity and practicality test. The data collection instrument were observation, validity and practicality questionnaires. The e-module was validated by 6 experts, consisting of 3 chemistry lectures of FMIPA UNP and 3 chemistry teachers while test was carried out by 2 chemistry teachers and 15 XII grade students of MIPA SMAS Adabiah 2 Padang. Data form validity and practicality test were analyzed using Aiken’s V technique. Based on the results of the study, it was found that average Aiken’s V index (V) of validity test was 0,83 with high validity category, the average Aiken’s V index (V) of teachers practicality test was 0,81 with high practicality category and the average Aiken’s V index (V) of students practicality was 0,82 with high practicality category. The results of the analysis of students answer on e-modules were obtained on average 90% on key questions, 94.8% on worksheets and 90% on evaluation sheets. Based on the results of the study it can be concluded that e-modules based on guided inquiry learning model and integrated with virtual laboratories on salt hydrolysis topic was valid and practical for chemistry learning in high school.
