This study aimed to examine the effect of educational software on 3rd-grade elementary-school students’ mathematical problem-solving skill. This was a quasi-experimental, pretest-posttest, controlled study. The statistical population comprised all 3rd-grade elementary-school male students in District 4 of Karaj (Iran) in the academic year 2018-2019. A sample was selected via convenience sampling, and the participants were randomly assigned to two experimental and control groups (20 each). On pretest, two tests of “numerical analysis” and “attention and concentration” (Wechsler test) and a researcher-made problem-solving skill test were administered. Then, the experimental group received eight 40-minute sessions of software training, while the control group received the class’s routine education. Finally, both groups took the posttest. The data were analyzed via univariate analysis of covariance and independent samples t-test. After the experimental intervention, the two groups demonstrated a significant difference (p < 0.001) at three levels of “problem-solving speed”, “attention and concentration”, and “numerical analysis”. The two groups also showed a significant difference at the level of “problem-solving strategy identification” (p < 0.05). Accordingly, the role of educational media, and especially educational software, can be highlighted in promoting students’ learning and mathematical problem-solving skill.

This study was conducted to investigate the effect of conversational style education through multimedia on increasing communication skills of female students. The research method was quasi-experimental and the statistical population included female students in sixth grade of District 2 of school system in Tehran(Iran), of whom 60 were selected by cluster sampling and placed in two groups of control and experiment. Data collection tools included Attar's standard communication skills questionnaire (2007) whose face validity was confirmed by eleven teachers using Delphi technique and its reliability through Cronbach's alpha coefficient for subscales, emotion management, others perception and assertiveness. It was equal to 0.92, 0.89 and 0.88, respectively. Research data were analyzed using SPSS.22 software. The results showed that there was a significant difference between the mean scores of the control and experimental groups regarding students' communication skills at the level of 95%. Students' communication skills in conversational style through multimedia were better than students trained in the traditional way. The results of this study indicate the positive role of interactive teaching through multimedia in increasing the communication skills of primary school students, and this emphasizes that schools and educational institutions need more multimedia tools to deepen Learn and enhance learners' communication skills.
