The aim of this study is the effect of multimedia education on understanding the concept and solving the mathematical problem of fifth grade students. The method used is a quasi-experimental type with pre-test and post-test and two experimental and control groups. The target population of this study was the fifth grade male students of Qarchak city who were studying in the academic year of 98-99 and the selected samples were randomly assigned to 60 students in two control groups (30) and 30 people were tested. The research tools were used for multimedia training of Aria e-bag software and for understanding the concept (spatial, spatial and temporal) and solving the mathematical problem that the researcher had asked. The validity of this test was 0.744 through Cronbach's alpha and its validity was confirmed according to experts. Data analysis collected in the study was performed using SPSS software and using descriptive statistical methods of mean indices, standard deviation and in the inferential statistics section, covariance analysis method was used. The results show that there is a significant difference between the mean of post-test scores of the two control and experimental groups in the dependent variable of understanding the concept and solving the mathematical problem. This confirms the effective role of multimedia teaching on better understanding of mathematical concepts (spatial understanding, spatial understanding and temporal understanding) and solving math problems of fifth grade students.

The present study aimed to investigate the effect of educational multimedia on the educable mentally retarded student’s growth of self-directed learning skills in first grade of high school in Tehran, has been done. The target population includes all educable mentally retarded students of first grade in high school in Tehran. With using multi-stage cluster sampling method, 12 students were selected and randomly were replaced in experimental and control group. Data, questionnaires, was Fisher and colleague’s self-directed learning Scale. After the pre-test on both groups, the independent variable (education by multimedia) were administered in six sessions on the experimental group and the control group were well away from the independent variable. After completing the education with multimedia, post-test was conducted in both of groups. The results showed that the experimental group in the component willingness to learn and management was significant progress compared to the control group, respectively. But in self-control components, there was no significant difference between control and experimental groups.

This paper attempted to evaluate the impact of educational multimedia based on Gagné’s Instructional Systems Design (ISD) on learning and retention of Natural Sciences among sixth grade students with intellectual disability. The methodology involved a quasi-experimental procedure, pretest-posttest and a control group. The population included all sixth grade female students with intellectual disability studying at special education centers of Khorramabad, Iran, during the academic year 2014-2015. Using convenient sampling, 30 students were selected and then randomly divided into two groups. The instrument used in this study was a researcher-made learning and retention quiz. The learning pre-test was administered by the researcher for both experimental and control groups. Then, the experimental group was trained through eight sessions using multimedia devices based on Gagné’s model, while the control group received the conventional treatment. Post-test was administered on both groups. The researcher administered the retention quiz on students two weeks after the completion of course. Statistical methods were employed at descriptive and inferential levels to analyze the statistical data. The findings suggested a significant difference between the experimental and control groups in terms of learning and retention rate. In fact, the experimental group achieved better learning and retention.

This study aims to investigate the effect of multimedia conversational instruction style on increasing communication skills in the student’s girls with partial hearing loss in Tehran. The research method is quasi-experimental and the statistical population is composed of all elementary school 6th-graders with partial hearing loss in Tehran out of whom 15 students were randomly selected using the convenience sampling method and placed in two control and experiment groups. The instrument for data collection is Attarha Communication Skill Assessment Inventory (2007) which has three subscales. The experiment group received training in 7 sessions using the researcher-developed multimedia software program, and the control group was excluded from training. Descriptive statistics (central and dispersion indices) and inferential statistics (univariate covariance analysis) were adopted for data analysis. The results generally suggest that multimedia conversational instruction style improves communication skills including emotional management, others’ perception and self-assertion in the students with partial hearing loss. Therefore, the results indicate that multimedia conversational teaching style has a positive impact on increased communication skills in the students with partial hearing loss.
