فاعلية أنموذج هيرمان في تحصيل طالبات الصف الرابع العلمي في مادة الأحياء

The research aims to identify the effectiveness of Herrmann Model in the achievement of Fourth-Scientific Class female students in Biology. The researcher has adopted the partial-control experimental method to adjust the research variables. The research sample consists of (70) student (35) student who have studied according to Herrmann model and (35) student who have studied according to normal method). Before starting the experiment, the researcher has made an equivalence between the two groups representing in variables (age by months, students' previous achievement in biology, testing previous information and intelligence test). Statistics have proved that the two groups of research are equivalent to those variables. After conducting the equivalence, the researcher has prepared application requirements including plans, goals and tests for the two groups of research. She has applied her research tools after completing the experiment application. After marking the student answers, she has obtained data for the experimental group and control group, where those data have been statistically processed by (T-test) for two independent samples. Results have shown superiority of the experimental group which has studied according to Herrmann Model over the control group which has studied according to the normal method in the studying achievement variable.
