The present research seeks to assess the impact of a researcher-made multimedia on the learning and retention of the Persian pre-printing skills. The participants were all the first graders of elementary schools in Teheran in the school year 2010-2011. 40 students were selected through multilevel random sampling to represent the experimental group (20 subjects) and control group (20 subjects). The method of the research was semi-experimental, and the used research plan was pretest-posttest with control group. Firstly, the researcher took a pre-test from both groups using a research-made exam, and then taught pre-printing skills to the experimental group using a research-made multimedia built on multimedia designing principles. Separately, the teacher taught the same pre-printing lesson using the traditional method. Finally, both groups were taken an exam. The results indicated an increase in alphabet-tracing learning, alphabet-tracing retention, eye/hand coordination skill learning and letter-shape recognition learning in comparison with the control group. The impact of the multimedia on the learning was confirmed while the increase of eye/hand coordination retention and letter-shape recognition retention were not confirmed. This shows that the multimedia can be effective in the learning of Persian pre-printing skills course but not necessarily in its retention in the long run.

Background: Today, can we overcome the limitations of time and place by using modern communication technologies. Realizing this fact, new educational systems, such as distance education system is an important issue. Objective: The aim of this research is to study the effects of multimedia and lecturing teaching methods on achievement motivation (internal and external motivation) of students Arabic (3) course of a distance education centers in Tehran. Method: The research statistics society is consisted of total girls' students on third grade human sciences of a distance education center in Tehran in the academic year of 1388-89. In order to select the desired sample, we used the multi-step cluster randomly sampling way. The amount of sample's number was 30 people, who was grouped into two 15 groups randomly. Then, one group was taught with multimedia method and the other, was taught by lecturing method. We evaluated the achievement motivation (internal and external) in two groups by Verland Test (1991), and then the obtained results were analyzed applying the covariance analyze test. Results: The result of this research indicated that, there was no meaningful difference between the degrees of achievement motivation in these two groups. Also, the obtained results indicated that there was no meaningful difference between the both groups, but in the level of sub- segments scales of internal motivation for doing the after of (development) and the internal motivation to figure out, there was a meaningful difference. While, there was no meaningful differences between the both groups, in the level of internal motivation scale to test the effect. Conclusion: It is suggested to apply appropriate teaching methods to increase the level of achievement motivation in students.

The purpose of this study was to investigate the effect of multimedia, sound and color on the brain waves of male undergraduate students. Population of the study was male students at the TarbiatMoallem University of Tehran. The sample consisted of 14 male students. The instrument of the study was EEG (SD-C24). The results indicated that:
(a) the use of multimedia had a significant effect on brainwaves at p<0.01 when eyes were open, (b) the use of sound had a significant effect on brainwaves at p<0.05 when eyes were shut, (c) there was no significant difference between sound and multimedia on brainwaves at p<0.05, and (d) there was a significant difference between sound, multimedia and colors on brainwaves at p<0.05.This investigation showed that multimedia affects the brainwaves. However, there was no significant difference between effects of sound and multimedia. Color in comparison to other two variables had a meaningful effect on the brainwaves. Therefore, in designing and developing the media, these factors must be considered. Since learning is the outcome of change of the behavior, it is reflected on the brainwaves.
