According to cluster sampling meth two classes from schools and 15 students from each class were selected randomly. These two groups were also randomly assigned to experimental and control group. Lichtenfeldet al. (2012) educational excitement questionnaire was used for information collection. Multivariate covariance (MANCOVA) test was used for hypotheses analyze. The results showed that implementation of multimedia education designing based on Sweller's cognitive load theory effects significantly on increasing educational excitement enjoy and decreasing educational excitement fatigue and anxiety. Experiment group mean in posttest was more than control group mean. It can be concluded, according to results, multimedia education designing based on Sweller's cognitive load theory can be used as one of the decreasing negative educational excitements and increasing positive educational excitement of students
