A proposed unit in green chemistry based on the Eisencraft investigative model to develop the depth of chemical knowledge, motivation towards environmental sustainability, and decision-making skills among first-year secondary school students.

    The aim of the current research was to measure the Effectiveness of a proposed unit in Green Chemistry based on the Eisencraft survey model to develop the Depth of Chemical knowledge, Environmental Awareness, and Environmental Decision-Making skills among first-year secondary school students. The research group consisted of (38) students from Al-Jaafra Secondary School for Boys, affiliated with the Daraw Educational Administration. In Aswan Governorate; To implement the research experience during the first semester of the academic year 2022-2023 AD, the researcher used: the descriptive approach in preparing the theoretical framework for the research and the proposed unit, and the research tools (test: depth of chemical knowledge, and two scales: environmental awareness and environmental decision-making skills), In analyzing and interpreting the results, and the experimental approach in the field part represented by the one-group experimental design that is based on pre- and post-measurement of the dependent research variables, the results showed the effectiveness of the proposed unit in developing the research variables, as was the rate of adjusted gain for “Blake” It is acceptable for the growth of chemical knowledge, environmental awareness, and environmental decision-making skills, and the size of the effect of the proposed unit on the research variables as measured using the value of (η2) was high. In light of these results, the researcher recommended the necessity of adopting the proposed unit in green chemistry based on the Eisencraft investigative model, and providing What is necessary for this in a way that helps develop the depth of chemical knowledge, environmental awareness, and environmental decision-making skills among first-year secondary school students, and holding training courses for chemistry teachers that address the nature of research variables and their importance for students of this stage in order to improve their abilities in a way that benefits them and their community, and provides teachers with the necessary skills and competencies. To use this model successfully in teaching, and to direct developers of chemistry curricula at the secondary level to the necessity of using the proposed unit in teaching chemistry to first year secondary school students.
