Validity and Practicality of Chemical Bonding E-module Guided Inquiry Basef Integrated Virtual Laboratory for High School

Abstract

The increasingly rapid development of science and technology allows for innovation in various aspects of life, one of which is learning activities. Innovations in learning activities can take the form of teaching materials from printed to electronic. This research aims to develop a printed module into an e-module on chemical bonding material based on guided inquiry in an integrated virtual laboratory that is valid and practical for high school. The development model used is 4D. The e-module validation test was carried out by UNP lecturers and chemistry teachers. The practicality test was carried out by chemistry teachers and students. The research instrument is a validity and practicality questionnaire. The validation questionnaire was analyzed using the Aiken's V formula and the practicality questionnaire was analyzed using descriptive statistical percentages. Based on research, the average Aiken's V was 0.86 with a valid category. The practicality value of the e-module obtained from teachers and students was 85.2% and 90.1% respectively in the very practical category. Based on the results of research on the chemical bonding e-module based on guided inquiry integrated with the virtual laboratory for high school, the result is valid and practical.
