الملخص EN

The aim of the current Research was to investigate the Eeffectiveness of a proposed unit and a proposed unit in Nanotechnology based on differentiated Instruction Strategies to develop the Scientific Culture and Motivation towards Science Learning among middle school students with Different Learning styles.

Bahri Joint Preparatory School of the Drau Educational Administration in Aswan Governorate; To apply the research experience in it during the academic year 2019/2020 during the second semester, and the problem of the current Research was identified in the low Scientific Culture related to Nanotechnology, and the weak level of Motivation towards Sscience Learning among first-grade middle school students, and the current research relied on the descriptive approach and the experimental approach , The researcher reached conclusions that there is a statistically significant difference at the level of (0.05) between the mean scores of the research group in the post application of my test: the Scientific Culture related to Nanotechnology, the measure of Motivation towards Science Learning, in favor of the post application, and the rate of gain adjusted for "Blake" was acceptable for the growth of scientific culture related to Nanotechnology, the drive towards Science Learning, and the size of the impact of the strategy is generally high in both: Scientific Culture, and the drive towards science learning.

Based on the research results, the Researcher recommended the necessity of reformulating and organizing the science curriculum units in the class.

The first preparatory school according to the "Differentiated Instruction Strategies", and the inclusion of the proposed Nanotechnology unit in the content of the Science Curriculum in the first intermediate grade, and the holding of programs Training for middle school science teachers with the aim of providing them with the skills and competencies needed to successfully use "Differentiated Instruction Strategies" in teaching, and adopting a clear strategy by the state; To spread awareness of issues related to nanoscience and nanotechnology, by intensifying relevant training programs, awareness leaflets, print, audio and video programs and advertisements.
