Given the transformative potential of technology-enhanced methods in language education, this study investigated the effect of AI-scaffolded learning-oriented assessment (LOA) on Iranian EFL learners' vocabulary acquisition. A quasi-experimental design was employed, with 40 male intermediate-level learners non-randomly assigned to an experimental group (AI-supported Nearpod platform with adaptive scaffolding) and a control group. The Oxford Placement Test ensured homogeneity, while the Vocabulary Knowledge Scale measured vocabulary gains. The experimental group received AI-driven scaffolding, including real-time adaptive feedback, tiered support, and interactive peer-review tasks aligned with LOA principles. Statistical analysis revealed a significant difference in post-VKS scores (M = 130.05) for the experimental group compared to the control group (M = 99.85), with a large effect size (t = 39.38, p < .001, d = 1.96). These results demonstrate that AI-scaffolding, when integrated with LOA, substantially enhances vocabulary learning by personalizing feedback and promoting active engagement. The study highlights the efficacy of AI tools like Nearpod in EFL contexts while underscoring the importance of pedagogical design, such as balancing automation with teacher guidance, to maximize learning outcomes. These findings advocate for the strategic adoption of AI-scaffolded LOA in language curricula, though challenges like digital literacy and equitable access warrant further exploration.

This study aimed to examine the mediating role of executive functioning in the relationship between parental involvement and math achievement among children with learning disabilities. A descriptive correlational research design was employed, involving 379 Malaysian parents of children aged 9 to 12 years diagnosed with learning disabilities. Participants were selected using stratified random sampling based on the Morgan and Krejcie (1970) sample size determination table. Data were collected using three validated instruments: the Parent and School Survey (PASS) to assess parental involvement, the Behavior Rating Inventory of Executive Function (BRIEF) to measure children's executive functioning, and the Math Composite of the Wechsler Individual Achievement Test–Third Edition (WIAT-III) for math achievement. Pearson correlation analysis was conducted using SPSS version 27, and structural equation modeling (SEM) was performed using AMOS version 21 to test the hypothesized mediation model and assess the model fit. Pearson correlation results indicated significant positive relationships among all variables: parental involvement and executive functioning (r = .41, p < .001), parental involvement and math achievement (r = .36, p < .001), and executive functioning and math achievement (r = .48, p < .001). The SEM revealed an acceptable model fit (χ²/df = 1.84, CFI = 0.97, RMSEA = 0.045), and confirmed that executive functioning significantly mediated the effect of parental involvement on math achievement. Both the direct effect (β = 0.26, p < .01) and the indirect effect through executive functioning (β = 0.18, p < .001) were statistically significant. The findings underscore the importance of executive functioning as a cognitive mechanism through which parental involvement enhances mathematical performance in children with learning disabilities. Educational interventions should integrate strategies to strengthen both parental engagement and children’s executive functioning skills to optimize academic outcomes.

The purpose of this research is to determine the effect of using new educational technologies (interactive PowerPoint) on the collaborative learning of sixth grade students. The present research is an applied research in terms of purpose and semi-experimental one in terms of data collection method. The selected research design is the pre-test-post-test design with a control group. The statistical population of this research (250) includes all the sixth grade students of Qazvin city, Lower Tarem region, in the academic year 2017-2018. Using simple random sampling method, 50 people (25 control group and 25 experimental group) were selected. The main data collection method is library research method. For data collect purpose, participatory and active learning questionnaire (Cho and Bavli, 2007) has been used. The data collection instrument is a package of using modern educational technologies (interactive PowerPoint). Content validity was checked to secure the validity of the research and Cronbach's alpha coefficient was used to determine the reliability of the instrument. The reliability of the questionnaire was found to be 0.85. In the descriptive statistics section, statistical characteristics such as frequency, percentage, mean, and standard deviation have been reported, and in the inferential statistics section, the KS test was employed to determine whether the variables are parametric or non-parametric. Also, one-variable covariance analysis was run using SPSS23 software. The results of the present study indicated that the use of new educational technologies (interactive PowerPoint) had a positive and significant effect on the group dynamics and project of the sixth grade elementary students. The findings of the present research also revealed that making use of use of new educational technologies (interactive PowerPoint) had a significant effect on the collaborative learning of students. It also indicated that the use of new educational technologies (interactive PowerPoint) had a significant effect on the dimensions of collaborative learning (group dynamics, doing work on the project, feedback) and students' feedback
