Development of Green Chemistry-Based Practicum Module for Senior High School to Promote Students’ Environmental Literacy

Abstract

Chemistry learning ideally should invite students to interact directly with the object being studied. This can be realized through a practicum in the laboratory. However, chemistry practicum still generates significant waste in the environment. There is also a need for character education to promote environmental literacy. Therefore, there is a need for a green chemistry-based practicum module for class X senior high school. This research aims to develop a green chemistry-based practicum module, to know the quality of a green chemistry-based practicum module, and to know the students' responses to environmental literacy. This a research and development using a modified Borg and Gall development model that includes information gathering, planning, product development, limited trial, and product revisions. The results of the validity of the green chemistry-based practicum module in terms of material had a percentage of 93.45% and in terms of media had a percentage of 90.00% with a very valid criterion. The use of the green chemistry-based practicum module gets a very practical criterion with a score of 86.67% based on students’ responses. The green chemistry-based practicum module effectively increases students’ learning outcomes which are marked by the n-gain value of 0.3 - 0.78 in the medium to high criteria. The value of tcount ttable and sig.(2-tailed) in three practicums 0.05 indicates that the green chemistry-based practicum module can support students' environmental literacy
