Abstract

Project-Based Learning has gained increasing attention as an instructional approach aligned with the demands of twenty-first-century education, particularly in fostering higher-order thinking and social competencies in primary classrooms. This study aims to examine the effectiveness of Project-Based Learning in developing critical thinking and collaboration skills among primary school students. The research employed a quasi-experimental mixed-methods design involving an experimental group taught through Project-Based Learning and a comparison group receiving conventional instruction. Quantitative data were collected through performance-based critical thinking tests and collaboration observation rubrics, while qualitative data were obtained from classroom observations and teacher field notes. The results indicate that students exposed to Project-Based Learning demonstrated significantly higher gains in critical thinking and collaboration than those in the comparison group. Qualitative findings further revealed improved student engagement, more balanced participation, and deeper peer interaction during project activities. The study concludes that Project-Based Learning provides an effective pedagogical framework for integrating cognitive and social skill development in primary education. These findings suggest that early implementation of learner-centered, inquiry-based instruction can support the cultivation of essential twenty-first-century skills without compromising curricular objectives. The implications extend to teachers, curriculum designers, and policymakers seeking evidence-based strategies for meaningful primary classroom innovation worldwide contexts.

Abstract

Parental styles play a significant role in shaping the development of children, influencing various aspects of their emotional, cognitive, and social growth. While much research has explored the immediate effects of parenting on children, few studies have examined these effects over an extended period. Understanding how different parental styles impact child development across time is essential for identifying long-term outcomes and informing parenting strategies. This study aims to investigate the long-term influence of different parental styles on child development, focusing on emotional regulation, social competence, and academic achievement. The goal is to explore how these parenting styles affect children at various developmental stages. A longitudinal design was employed, with data collected from 200 families over a span of 10 years. Parenting styles were categorized based on the authoritative, authoritarian, permissive, and uninvolved frameworks. Child development was measured using standardized assessments for emotional regulation, social competence, and academic performance. The findings revealed that children of authoritative parents showed higher levels of emotional regulation, better social skills, and stronger academic performance compared to children of authoritarian, permissive, or uninvolved parents. This study underscores the importance of authoritative parenting in fostering positive long-term outcomes in child development.

Abstract

Manual Requirement Engineering (RE) in Agile software development creates a significant bottleneck. The reliance on natural language user stories at scale results in high-volume backlogs prone to ambiguity, duplication, and incompleteness, leading to costly, downstream development defects. This research aims to design, develop, and empirically validate a novel, hybrid Natural Language Processing (NLP) framework, termed the Agile Requirement Quality (ARQ) framework, to automate the detection of these common requirement defects. The goal is to reduce cognitive load and improve defect detection velocity during backlog refinement. A mixed-methods Design Science Research (DSR) methodology was employed. We developed the ARQ artifact (a hybrid BERT and heuristic model) and validated it both in-vitro against a 5,000-story “gold standard” annotated corpus (Fleiss’ Kappa 0.86) and in-situ through a quasi-experiment with professional Agile teams. The findings demonstrate high efficacy. In-vitro validation achieved high accuracy (overall 95.2%, with F1-scores of 0.87 for ambiguity and 0.94 for duplication). The in-situ experiment was conclusive: the ARQ-assisted team achieved a 73% increase in defect detection and an 87.5% reduction in “defect leakage” compared to the control team, registering high usability (88.5 SUS). This study provides robust empirical evidence that NLP-driven automation is a viable, high-impact strategy for mitigating risk in Agile RE. The framework functions as a practical “augmented intelligence” tool, significantly reducing defect leakage and improving quality assurance velocity.

Abstract

Epigenetics plays a crucial role in how plants adapt to environmental stressors such as drought, salinity, and extreme temperatures. Understanding the mechanisms behind epigenetic modifications can provide insights into plant resilience and survival strategies in changing environments. This study aims to investigate the role of epigenetic mechanisms in plant adaptation to various environmental stressors. By examining specific epigenetic modifications and their effects on gene expression, the research seeks to elucidate the pathways through which plants respond to stress. A combination of field experiments and laboratory analyses was employed to study epigenetic changes in selected plant species exposed to different environmental stress conditions. Techniques such as DNA methylation profiling and histone modification analysis were utilized to assess epigenetic alterations. Findings indicate that epigenetic modifications, including changes in DNA methylation and histone acetylation, play a significant role in regulating gene expression in response to stress. Certain stress-induced epigenetic changes were associated with enhanced tolerance to adverse conditions, suggesting a vital adaptive mechanism for plants. This research highlights the importance of epigenetics in understanding plant adaptation to environmental stress. The findings contribute to the growing body of knowledge regarding plant resilience mechanisms and may inform breeding programs aimed at developing stress-tolerant plant varieties

Abstract

Conventional cancer treatment is often limited by side effects and resistance to therapy. Therefore, immunotherapy research, especially those involving gold nanoparticles (AuNPs), is growing as a more effective and specific therapeutic alternative. AuNPs have the potential to modulate the body's immune response, improving the recognition and destruction of cancer cells by the immune system. This study aims to investigate the immunomodulation mechanisms triggered by AuNPs and evaluate their potential as cancer therapeutic agents by increasing immune cell activity and cytokine production. This study used cell culture to test the effects of AuNPs on the activity of T cells, macrophages, and dendritic cells as well as the production of cytokines IL-2, TNF-?, and IL-12. Gold nanoparticles were applied at various concentrations (5, 10, 20 ?g/ml) and treatment times (24, 48, 72 hours), then measured using flow cytometry and ELISA. The results showed that AuNPs increased the activity of immune cells, especially dendritic cells, macrophages, and T cells, as well as the production of cytokines IL-2, TNF-?, and IL-12. This increase in immune cell and cytokine activity is directly related to the concentration and duration of AuNPs treatment. This study shows that AuNPs can modulate the body's immune system and increase the immune response to cancer. Gold nanoparticles have the potential as immunomodulatory agents in more effective and safe cancer therapy. More research is needed to confirm these findings in animal and human models.
