Designing a multimedia-based instructional unit for teaching science to the second grade intermediate school students

The research aims to design a multimedia-based instructional unit for teaching science to the second grade intermediate school students. To achieve this goal, the researchers began the design process, through several steps and stages of producing electronic lessons. After reviewing a number of computer programs that allow the design and implementation of such lessons, the researchers chose (MS Power Point) and (BB Flashback software). After obtaining the curriculum and book for science in the second grade of intermediate school, a number of behavioral objectives were formulated that are expected to be achieved through the instructional unit. The researchers relied on pictures, figures, and diagrams included in the book, and then added a number of illustrative pictures and educational videos specifically designed for this purpose.The instructional unit was designed and then presented to a committee of experts in educational psychology and educational sciences, and obtained a good acceptance rate of over (80%). The researchers selected a random sample of (30) female students from Ninawa intermediate school to apply the instructional unit in order to assess the ability of the students to use it. They also calculated the time required to execute each lesson and ensured that appropriate programming environments were available for implementing such lessons. Based on these results, some concepts were reformulated, and the pictures, backgrounds, and text styles were changed. The instructional unit was then ready for implementation and use. Based on these findings, the researchers drew several conclusions, recommendations, and proposals
