تحليل محتوى كتابي العلوم (وحدتي الكيمياء) للمرحلة المتوسطة على وفق المشكلات البيئية
The main goal of the current research is to identify the environmental problems included in the content of the two science books (chemistry units) at the intermediate stage. A list of environmental problems had been prepared that consisted of (8) main areas, which are (air and atmosphere pollution, water pollution, soil pollution, energy, disturbance of biodiversity and environmental balance, waste management, food and medicinal pollution, and investment of mineral wealth) were (60) sub-problems. The researcher analyzed the two science books of the intermediate stage for the academic year (2020-2021) in light of a prepared list. The results showed that the two science books (two chemistry units) of the first intermediate grade achieved (19) sub-problems with a percentage of (31.66%). The two science books for the second intermediate grade achieved (15) sub-problems with a percentage of (25%). Finally, the researcher recommends including the content of the two science books (two units of chemistry) for the intermediate stage, the main and sub-environmental problems that are not available as one of the modern trends in science education based on the environmental problems themselves.
