AU - المنتشري، تغريد عبد الله AU - الفراني، لينا بنت أحمد بن خليل AB - The study aims to develop Fluency skill in the mathematics course, and to reveal the impact of using the 3D design program according to the integrated approach of STEM in the development of Fluency skill in grade 7 students. The quasi-experimental approach was use in one group design with pre and post-test of creative thinking skills, and a product assessment card to evaluate students' projects as a product of the learning process. The sample study was composed of (16) middle grade female students who were randomly selected. Overall, the results were positive, as there were statistically significant differences at level (p ≤ 0.05) emerged between the average of students’ grades in the pre and post-test of the creative skills test for the benefit of the post-test. This shown the positive use of 3D design based on STEM model to develop Fluency skill. The results also showed statistically significant differences at level (p ≤ 0.05) between the average grades of the experimental group and the default grade of perfection in the product evaluation card, indicating the evolution of Fluency skill using 3D design programs in middle grade students. The study recommended providing STEM labs with the latest technology such as 3D printer, virtual reality and robots are crucial to activate them in the educational process and performing more studies on this subject.
