Abstract
The present study was conducted with the aim of investigating the effectiveness of external cognitive teaching in a multimedia way on the self-regulation of learners.
Method: The present study was a semi-experimental study with a pre-test-post-test design with a control group. The statistical population of the research includes all elementary school students of Houshmanshahr schools in Tehran. With the aim of removing the intervention effect, available sampling method was used. Based on this, 30 students who were taught by an experimental science teacher were selected and randomly placed in experimental and control groups of 15 people. During 15 sessions of 40 minutes, the experimental group was exposed to the independent variable (educational multimedia based on Merrill's educational design model). The control group was taught the content of the experimental science course, which was designed according to Merrill's educational design model, in the usual teaching method. Students in both groups answered Bronken, Plus and Leutner questionnaires before and after training. The collected data was analyzed with spss software.
Findings: The results of the paired t-test showed that the use of multimedia education based on Merrill's design model reduces external cognitive load and increases self-discipline of learners. Also, it was found that the experimental group with multimedia training based on educational design model experienced more external cognitive load and had more self-regulation than the control group with multimedia training without educational design model.
