أثر استخدام مبادئ و أنشطة هندسة الفراكتال في تنمية مهارات التفكير المنظومي و مهارات اتخاذ القرار في الرياضيات لدى تلاميذ المرحلة الإعدادية

Abstract EN

The study aims at finding out the effect of using fractal geometry principles and activities in developing first year prep stage students' systematic thinking and decision making skills in Fayoum Governorate.

The sample was made up of 76 students sub-divided into two groups; 38 students in the experimental group and 38 in the control one.

The researcher re-designed the (geometry and measurement) unit included in the 2016/2017 student book of the second term in light of the fractal geometry activities principles and characteristics.

The researcher prepared the following tools: Systematic thinking skills test and mathematics decision making skills measure.

The researcher ensured the validity and reliability of the study tools and the equality of the two groups of the study then implemented the experiment.

The study revealed the following: The experimental group members outdid the control one in both tools as there were statistically significant differences in the post implementation in favour of the experimental group.
