The aim of study was toinvestigate the effect of learning and content sustainability on interns of Semnan University ofMedical Sciences in two methods of lecture and compact discs.Methods : This study was a semi-experimental study. Our study was conducted on all the internsof Semnan University of Medical Sciences in 2016-2017. The sample size included 110 peoplewho were randomly divided into two groups. The students allocated into two groups and assignedto a lecture group and the CDs group. In a group, disaster management and control of nuclearpollution training were lecture-based and in the other group were CD-based. For evaluation andcomparison of the effects of the intervention on learning, three multiple-choice question tests wereadministered at the beginning and at the end of the training course and 4 weeks after theintervention. The mean and standard deviation of the scores in each step were compared for eachgroup and the two groups were compared by independent t-test in each stage. All data wereanalyzed by SPSS software version 16. 0.Results : The results showed a significant difference in the amount of response to previousquestions after the training. This difference was more in the CD method than in the lecture, andthe same response in the one-month test showed a significant difference between the CD and thelecture(p<0/001). Indicates the reliability of the content. Also, age and gender did not affectamount of learning.Conclusion : Multimedia education was more effective than lecturing on content sustainabilit y.However, the combination of these two methods probably will increase the effectiveness of thetraining method.
