الملخص EN

A suggested unit based on the principles of green chemistry and its applications to develop the knowledge side and decision-making skills of students of the Chemistry Department at the College of Education


The current research aimed to determine the effectiveness of a suggested unit in green chemistry to develop the knowledge and take decision making among second year at the Faculty of Education, Benha University, Chemistry Division.

The study group included (41) male and female students.

Two research tools were applied previously to the study group, and after completing the teaching unit "green energy and its application technology" then applying the two tools laterally.

The results indicated that there is statistically significant difference (0.01) between the mean scores of students of the study group in the pre and post applications to test the cognitive aspect of green chemistry in favor of post-test, and the presence of a statistically significant difference (0.01) Between the mean scores of students in the study group in the pre and post scale of decision-making towards environmental problems and issues in favor of post-scale, which indicates the effectiveness of the unit presented in developing the cognitive aspect and decision-making skills of students.

the study recommended Include its chemical innovations and all that is new in the decisions of the chemistry program at faculties of education and include decisions of chemistry activities and exercises that contribute to the development decision-making skills.
