The present research is a quasi-experimental study with two groups (before and after training). This study compared the two methods of lecturing training and education by the multimedia software. Two selected battalions were considered in which each battalion had 300 person-als. Based on the entry and exit criteria and preliminary test of measuring the knowledge (cognitive domain) (1). Those personals were selected whose scores were less than 60% of the test (200 in the first group and 180 from the second group). 30 personals were selected randomly organized from each battalion. These personals were trained with self-aid and body-aid techniques by using the lecturing method and multimedia software training. The necessary sample size in each group was estimated by Altman Nomogram (2), about 28 cases respectively. 30 cases were calculated with the probability of 10% detachment in the sample size. Namely, a total of 60 personals were considered in both groups. The initial conditions for participation in the statistical community were the followings: diploma education and above, obtaining preliminary test scores of less than 60%, no previous training in self-aid and body-aid, to be whether in the first or second decades of service. These cases were also the initial conditions for participation in the statistical community of multimedia software packages group: minimal familiarity with Microsoft Windows software, having a personal computer and the ability to use a multimedia CD (3). The pre-test in both groups was consisted of 38 written standardized questions. The validity and reliability were assessed as formal and substantive. The questions related to the cognitive domains (knowledge) were performed before the intervention (4). Then, the face to face training was conducted for the first group (5). This training was included the followings: lecture, questioning and answering and self-aid and body-aid educational booklet (prepared and notified by Training Deputy Joint Staff of the IRGC). The non-attendance training was considered for the second group. The educational package was provided for this group containing the following items: multimedia educational CD with the content of self-aid and body-aid (prepared and notified by Training Deputy Joint Staff of the IRGC) (6). The reliability and validity was confirmed by the editorials. The content of this educational package included: literature, printed CD, slides, images, audio, video and tests. Teaching was performed without limits of time and the …
