فعالية استخدام المنصة التعليمية التفاعلية (Edmodo)‎ في تنمية مهارات حل المشكلات و الاتجاه نحو مادة البيولوجي لدي طلاب المرحلة الثانوية بمدارس (STEM)‎

الملخص EN

The current research aimed to develop problem-solving skills and the attitude towards biology among secondary school students in STEM schools using the interactive educational platform (Edmodo), which was represented as the experimental treatment subject; Where it was used as an independent variable with a sample of second-year secondary students in STEM schools for the academic year 2018/2019 from the School of Excellence in Science and Technology in Kafr El-Sheikh Governorate as an experimental group that consisted of (45) students, while the method used in STEM schools was used with a control sample of The same school consisted of (45) students as well.

The tools of the research included: a test of problem-solving skills, and a scale of attitude towards biology, both of which were prepared by the researcher.

The descriptive analytical approach and the semi-experimental approach with the experimental and control groups were used, with the application of the pre and post measurements of the research tools on the two research groups.

The data was processed after the pre and post application of the research tools through the use of the SPSS, version 22.00 program, and the averages and standard deviations were calculated, and the "t" test was used to calculate the differences between the mean scores of the two groups, and Using the Eta square equation h2 to measure the impact of the learning strategy using the platform (Edmodo), and (Pearson correlation coefficient) was used to calculate the correlation coefficient between the two research tools.

Accordingly, the results of the search for the following resulted in: the presence of statistically significant differences at the level of 0.05 in both the problem-solving skills test and the scale of attitude towards biology in favor of the experimental group, and also resulted in the presence of an effect of using the interactive educational platform Edmodo in developing problem-solving skills and attitude towards biology among the research sample, and a positive correlation was found between the results of the two tools in the post test of both the experimental and control groups.
