A1 أبو الحمد، زينب طاهر توفيق. AB The present study aimed at examining the effect of a proposed program in fractal geometry on optical thinking and achievement of female students of mathematics department, college of science and arts at Najran University, in the academic year 1437-1438 H. This research used the quasi experimental method. To achieve this purpose, the following tools were prepared: 1) A proposed program in fractal geometry. 2) An achievement test in fractal geometry. 3) Optical thinking test. The sample of the study consists of 21 female Students of level 7 mathematics department, college of science & rats at Najran University. The results showed a statistically significant difference at 0.01 between the scores of the students of the research group in pre-test and post-test of the Achievement test and the visual thinking test in favor of the post test.
