فاعلية برنامج تدريبي في تنمية ممارسات معلمي الرياضيات بالمرحلة المتوسطة لاستراتيجيات تدريس مهارات التفكير العليا بمحافظة جدة
The study aimed to investigate the effectiveness of a training program in developing the practices of mathematics teachers at the intermediate stage of strategies for teaching higher-order thinking skills in Jeddah, and the experimental approach with a semi-experimental design was used on a random sample of (30) teachers from mathematics teachers, and a performance observation card for math teachers has been used for applying the strategies for higher thinking skills development, pre-prepared by the researcher, and they were trained in the prepared training program, then the observation card was post-applied. The data were collected and analyzed statistically, and the results of the test (T) of the correlated samples showed a statistically significant difference at (α ≤ 0.05) between the average experimental group scores between the pre and post-applications on the observation card for the application of (the problem-based learning strategy, a self-questioning strategy, and a solution strategy for the mathematical issue) for teaching higher-order thinking skills in favor of post-application, as the results of the Modified Blake's Gain Ratio showed the effectiveness of the training program in providing middle school mathematics teachers (study sample) strategies for teaching higher-level thinking skills as a whole. The researcher recommends giving attention to in-service training for mathematics teachers on the use of higher-order teaching skills in mathematics curricula at the intermediate level and enabling them to apply those skills, by reducing the teaching burden.
