<![CDATA[The abstract nature of many mathematical concepts presents a significant pedagogical challenge in elementary education, often leading to difficulties in student comprehension. The integration of multimedia, such as learning videos, offers a promising avenue to make these concepts more concrete and accessible. This study aimed to quantitatively determine the effectiveness of using learning videos on elementary school students’ understanding of mathematics concepts. A quasi-experimental, pre-test/post-test non-equivalent control group design was employed. The sample consisted of two fifth-grade classes, with one class (N=32) assigned as the experimental group utilizing learning videos and the other (N=32) as the control group receiving conventional, textbook-based instruction. Students’ conceptual understanding was measured using a validated, standardized mathematics concept test. Data were analyzed using an independent samples t-test and normalized gain scores. The results revealed a statistically significant difference in the post-test scores between the two groups (p < 0.01), with the experimental group demonstrating a substantially higher mean score and a significantly greater normalized gain. The study concludes that the use of learning videos is a highly effective instructional strategy for improving students’ understanding of mathematical concepts in elementary school.]]>

<![CDATA[Prosocial behavior—voluntary actions intended to benefit others—is a cornerstone of functional societies. While its benefits for the recipient are clear, a growing body of research in positive psychology suggests that engaging in altruistic acts may also be a powerful and often overlooked pathway to enhancing the actor’s own psychological well-being and overall life satisfaction. This study aimed to empirically investigate the relationship between the frequency of engaging in prosocial behavior and self-reported levels of psychological well-being and life satisfaction in a diverse adult population, and to determine if this relationship holds after controlling for key demographic variables. A cross-sectional survey design was employed with a sample of 450 adults (aged 25-65). Participants completed a battery of validated instruments, including the Prosocialness Scale, the PERMA Well-being Profiler, and the Satisfaction with Life Scale (SWLS). A strong, positive correlation was found between prosocial behavior and both well-being (r = .51, p < .001) and life satisfaction (r = .48, p < .001). The regression analysis revealed that prosocial behavior remained a significant and unique predictor of both outcomes even after controlling for all demographic variables. It accounted for a substantial portion of the variance in both well-being and life satisfaction scores. Engaging in prosocial behavior is a robust and significant predictor of higher psychological well-being and greater life satisfaction. The findings suggest that altruistic actions are not merely a consequence of happiness but are an active ingredient in creating a fulfilling life.]]>
