فاعلية برنامج قائم على التعلم البنائي في تنمية مهارات التفكير النحوي لدى طالبات المرحلة الثانوية في الجمهورية اليمنية
The aim of the research is to determine the effectiveness of a program based on constructive learning in developing grammatical thinking skills among female students in secondary schools in the Republic of Yemen. To achieve this goal, the researcher used descriptive and quasi-experimental methodologies, prepared a list of grammatical thinking skills, a test to measure these skills, and an educational program based on the constructive learning model. The research sample consisted of 100 female students from the first grade of secondary school in the capital city of Sana'a, who were purposefully selected and divided into two groups: the experimental group studied using the constructive learning program, and the control group studied using the conventional method. The research reached the following results: 1) There is a statistically significant effect at the significance level (0.05) for the effectiveness of the program based on constructivist learning in developing grammatical thinking skills among first-year secondary school female students. 2) There are statistically significant differences at the significance level (0.05) between the average scores of the experimental and control groups in the post-application of the grammatical thinking skills test in favor of the experimental group. These differences are attributed to the program based on constructivist learning. 3) There are statistically significant differences at the level of significance (0.05) between the average scores of the female students of the experimental group in the pre- and post-applications of the grammatical thinking skills test in favor of the post-application as a result of using the program based on constructivist learning.
