تطوير بيئة للتعلم المدمج قائمة على نمطي الدمج (التتابعي/ التشعيبي) وأثره في تنمية المفاهيم العلمية لدى تلاميذ التعليم الأساسي
The aim of this research is to develop the scientific concepts through an environment for the blended learning on the two blended patterns (Flow/ Core and Spoke) among the basic education students. To achieve this goal, a list of scientific concepts was identified and create two strategies for blended (Flow/ Core and Spoke), the criteria of designing for the blended learning with the two blended patterns (Flow/ Core and Spoke) were determined, and developing the blended learning environment with its two blended patterns (Flow/ Core and Spoke) according to the design criteria and as per Al Jazzar Model (2014) for educational design. To achieve this goal, the researchers prepared achievement test to measure the development of scientific concepts. The research followed the developmental research, which is based on the Systems Development Method, which is the integration of three consecutive Methods to the research (Elgazzar, 2014), namely: The descriptive and analytical research method, to answer the first and second sub-questions of the research questions. The Systems Development Method, to answer the third sub-question of the research questions, and the experimental research method, to answer the fourth subquestion of the research questions. The researcher used the Semi-experimental design for 2 experimental groups with the pre and post measurement, and the research sample reached (40) students from the fourth grade of primary school, who were divided into 2 groups randomly according to Blended patterns (Flow/ Core and Spoke), and the results showed a basic effect of the two Blended patterns (Flow/ Core and Spoke)in the blended learning environment on the post application of the achievement test to measure the development of scientific concepts, in favor of the Core and Spoke blended pattern.
