Students with specific learning disorders (SLD) have major difficulties in learning and using listening, speaking, reading, writing, and math skills. The present study aimed to investigate the effectiveness of proprioception-enhancing exercises on dyslexia and dysgraphia in students with SLD. The research method was quasi-experimental with a pretest-posttest design and a control group. The study population consisted of all girl and boy elementary school students (2nd and 3rd grades) with SLD who received educational and rehabilitation services from public and private centers for learning disorders in Ahvaz, Iran in 2022. Using convenience sampling, 30 students were selected and randomly assigned to the experimental and control groups (n= 15 per group). The participants in the experimental group received proprioception-enhancing exercises in twelve 45-minute sessions, whereas those in the control group received no intervention. The research instruments included the Reading and Dyslexia Test and Dysgraphia Test. The data were statistically analyzed using analysis of covariance (ANCOVA). According to the demographic results, the mean age of the students in the experimental and control groups was 8.64±2.31 and 8.30±2.47 years, respectively. The results showed that proprioception-enhancing exercises were effective in improving dyslexia and dysgraphia in students with SLD (p<0.01). It can be hence concluded that proprioception-enhancing exercises improve not only dyslexia and dysgraphia in students with SLD but also their academic performance.

This study aimed to determine the effect of educational packages based on executive functions on students' working memory. This was a quasi-experimental pretest-posttest study with a control group. In this study, the statistical population was all fifth-grade male students of Shahreza city located in Iran in the academic year 2020-2021. A boys' primary school and 40 students were selected using the available sampling method randomly. Experiments and controls were replaced in two groups of 20 people. The experimental group underwent 10 sessions of training based on executive functions; The control group did not receive any intervention. The data collection process was performed in the pre-test and post-test stages with Daniman and Carpenter's (1980) working memory scale for all participants in two groups. The collected data were analyzed by the ANCOVA method. ANCOVA results showed that performance-based education increased the working memory of students in the experimental group compared to the control group in the post-test (P<0.05). According to the results, the educational package based on executive functions can be used to increase the working memory of students in schools and educational centers.

The use of technology-based instructions and treatment tools to compensate for deficiencies in autism spectrum disorder (ASD) is evidently increasing. The present study that performed during 2021-2022 was a systematic review and meta-analysis concerning the efficacy of digital technologies in improving the deficient communication skills in language learners with ASD. Ten studies met the inclusion criteria. The results revealed that the overall effect size (Cohen’s d) was 0.12 for both fixed effect model and random-effect model (z = 1.155, p >0.05). The effect size was statistically non-significant. We also considered Magnitudes of Cohen’s d fixed at 0.2, 0.5, and 0.8 which commonly accepted for small, medium and large quantities. Again, the result approached the small magnitude (1.12 > 0.2). Despite estimation of variances of effect sizes across studies (Q index, I2 and T2 values) approved homogeneity in study results, due to small number of studies included in this meta-analysis they\ results may not be generalizable (Q= 8.780, I= 0.00, T= 0.00, p> 0.05). For future comparisons, we therefore recommend use of more evidence-based experimental studies with modifications in their technology devices to secure higher statistical gains. We also recommend considering moderator variables which affected the effect size of included publications consisting age, IQ level, treatment durations and validity rate of technology devices.
