The purpose of this paper was to evaluate the effectiveness of a four-component multimedia-based instructional design model in learning complex issues. To achieve this purpose, a quasi-experimental approach with pretest/posttest with control group was used. All sophomore high school male students in Karaj comprised the population of this research. The sample was selected through cluster sampling method including 60 subjects who were divided in three groups (experimental 1, experimental 2 and control group). Intended subject matter was presented to the control group with the traditional teaching methods and the first experimental group was taught with common multimedia software available on the market and the second experimental group was instructed with multimedia software designed with four component multimedia-based instructional design model. Then, for all the three groups, the pre-test and post-test were conducted. Data gathering tool was a researcher-made test with a reliability of 0.84. Covariance analysis and Scheffé post hoc test were used to analyze the data. The Results showed that there was a significant difference between the scores of the control and experimental groups. The dependent variable, that is, the students’ learning in the class based on the common multimedia software was better than the group that was trained with traditional method. In addition, students being taught with four-component multimedia-based instructional design model were better than students who were taught with common multimedia software. Accordingly, it is recommended that in teaching complex issues, potentialities of multimedia based instructional model, particularly the four-component instructional model, be used to teach complex subjects.

The present study aims to investigate the effecs of multimedia design education based on the principles of cognitive theory on learning, remembering and educational progress motivation of grade-five female students at math. the study was pseudo-educational and pretests and posttests administered to the control group. The population of the study includes allfemale students at grade five across the city of Ahvaz. The sampling of the study was done according to multi-level cluster sampling from Ahvaz, area4. Among the schools of this region, Bahar School with 325 students was chosen. Fromthe five grades in school only grade five students were taken into account.At this grade two classes named A and B, each with 30 students were available. Due to lack of cooperation of the teacher in classB, onlythe classA was considered.Next, thestudents were devided into two groups:control and experimental group(15 students each).Data collection instruments include two learning and remembering tests devised by the author and Keller's educational progress questionnaire (1993).In order to analyze the data covariance analysis tests were used. The results of the study showed that educational multimedia design based on principles of cognitive theory has an effect on learning,remembering and educational progress motivation of female students at grade five.
