AbstractGreen chemistry is an educational approach that is guided by Sustainable Development Education which aims to provide students with the knowledge of scientific solutions on how to solve environmental pollution. This study aimed to develop an instrument to gauge students’ level of green chemistry experiment, knowledge, attitude and practice and to test the usability of the questionnaire developed to explore students’ green chemistry experiment, knowledge, attitude and practice. This quantitative research employed a newly self-constructed Green Chemistry Awareness Questionnaire. The instrument validity and reliability is estimated by two experts and the reliability of the instrument was estimated during the pilot test, yielding Cronbach’s alpha value of 0.926. Questionnaires were distributed to 100 chemistry students from five secondary schools in Muallim district. Data was analyzed using descriptive and inferential statistical analysis to address all research questions. The indepen.....
