Designing a Multimedia Instruction based on Sweller's Cognitive Load Theo-ry And Determining Its Effect on the Engagement and Transfer of Math Learning Among Third Grade Primary School Learners

The purpose of this study is to design a multimedia instruction based on the Sweller's Cognitive Load Theory and its impact on the engagement, and transfer of learning Math subject in the 3rd grade students of elementary school. The quasi pre-, post-test, with control group were used in this research. The statistical population were all of 3rd grade students of elementary school in Chaipareh (502 students) in 1396-1397 school year. According to the cluster sampling method two classes from two schools and 15 students from each class were selected randomly. These two groups, in its own, were also randomly assigned to experimental and control groups. The data were collected using of the academicl engagement questionnaire of Shufley & Becker (2006), and the test of transfer of learning in case of the Math (designed by the researcher). Analyzing hypotheses with MANCOVA and t test indicated that the teaching basis of a multimedia instruction based on the Cognitive Load Theory on the students has also a positive effect on the academic engagement including skills, commitment and absorbtion components and transfer of learning of math lesson. according to the findings of this research, it can be concluded that a multimedia instruction based on the Sweller's Cognitive Load Theory is possible to be regarded as one of the efficient ways for expand the level of learners' engagement in classroom learning process and transfers it to a newer and higher educational situations.
