The researcher used three tools, namely the environmental knowledge test, which consisted of (25) Questions, a design thinking skills test consisting of (20) questions, and a measure of the attitude towards sustainable environmental development consisting of (25) statements. The validity of the tools was verified by presenting them to (10) experienced, and the stability of the tools was verified. The tools were applied to an exploratory sample from outside the study sample by calculating the reliability coefficient for internal consistency using the Cronbach alpha method, which reached (0.922) in the environmental knowledge test, (0.839) in the design thinking skills test, and (0.839) in the attitude towards measure. Sustainable environmental development, which are high rates and educationally acceptable to achieve the purposes of the study. The study found that there were statistically significant differences at the level of significance (α ≤ 0.05) in the environmental knowledge test, the design thinking skills test, and the measure of the trend towards sustainable environmental development for the benefit of the group. Experimentally, and in light of these results, the study recommended the need to enhance the use of artificial intelligence applications in education, and develop the social studies curriculum to suit the updates of artificial intelligence applications. The study came out with some proposals, including conducting studies that reveal the impact of the artificial intelligence chat application ChatGPT on developing academic achievement and thinking skills.
