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.

Background: This study aimed to design and apply a self-care training package for elementary students’ health. According to the purpose of the study, two hypotheses were posed. The first hypothesis states that the self-care training package is effective for the elementary students’ health improvement and the second hypothesis is that the self-care training package is effective in promoting the health components of elementary students. Method: This research was experimental with pretest-posttest and control group design. The statistical population of the study was all elementary students of public schools in Tehran city in the academic year 2019-2020. In this study, the health questionnaire and a researcher-made self-care questionnaire were used to collect the required data. In compiling the training package, the topics were divided into eight dimensions or topics of self-care including physical, nutritional, psychological, social, sleep, virtual, sexual, and health components. Results: The results of the study showed that the self-care training package was effective in promoting primary students’ health. Conclusion: It also was effective in promoting each health component (physical health and mental health) in primary school students.
