A STEM Teachers’ Perspective: Mobile Application Consumption and Their Impact on Students' Creative Academic Performance
This study examines the effect of professional development (PD) programs on STEM teachers’ capacity to integrate STEM content into K-12 classrooms in China, employing a rigorous mixed-methods design. The study combines a systematic literature review (SLR) of empirical studies (2016–2023) from major databases (Web of Science, Scopus, ERIC, and CNKI) with quantitative data collected through stratified random sampling of 550 participants (150 teachers, 200 students, and 200 parents) across rural Chinese high schools. The methodology features: (1) a PRISMA-guided systematic review with strict inclusion criteria focusing on STEM PD outcomes and (2) crosssectional surveys analyzed via SPSS regression to examine relationships between PD participation and teaching efficacy/student outcomes. Thematic findings revealed that mobile apps enhance interactive learning but face adoption challenges due to infrastructural gaps and inadequate teacher training. Quantitative results aligned with the technology acceptance model (TAM), indicating that perceived usefulness (PU) and perceived ease of use are primary drivers of adoption, while perceived risk (PR) negatively impacts behavioral intention. The study concludes that mobile learning holds significant potential for STEM education, but it requires targeted professional development, equitable resource allocation, and risk-mitigation strategies to achieve a scalable impact. Practical implications include policy recommendations for integrating mobile technologies into teacher training programs and addressing socioeconomic disparities in digital access
Applied Informatics in the Sphere of Medical Informatics Innovation: A Review Article
This systematic review critically examines the pivotal role of applied informatics in advancing medical innovation, with a particular focus on the integration of artificial intelligence (AI) and machine learning (ML) technologies. By bringing together recent research, the study demonstrates how these computer tools can transform healthcare, particularly by enhancing the accuracy of illness diagnosis using advanced medical imaging and enabling real-time patient monitoring. New trends in the field indicate that deep learning (DL), the Internet of Things (IoT), and intelligent computer systems are being increasingly utilized, all contributing to enhanced patient care and the development of more effective healthcare systems based on data. The review also examines foundational enablers for sustainable innovation, including the standardization of medical data formats, interoperability across health information systems, and the implementation of robust cybersecurity protocols to safeguard patient privacy and ensure data integrity. While the integration of AI and ML is primarily perceived as beneficial within the healthcare domain, the review identifies several persistent challenges. These include issues of clinician trust in algorithmic decision-making, the need for ethically sound implementation practices, and the development of evolving regulatory frameworks to accommodate rapid technological change. Additionally, the application of ML and data mining in predicting outcomes and aiding clinical decisions shows enormous potential, which could transform how we approach preventive and personalized medicine
Open, Small, Rigmarole – Evaluating Llama 3.2 3B’s Feedback for Programming Exercises
Large Language Models (LLMs) have been subject to extensive research in the past few years. This is particularly true for the potential of LLMs to generate formative programming feedback for novice learners at university. In contrast to Generative AI (GenAI) tools based on LLMs, such as GPT, smaller and open models have received much less attention. Yet, they offer several benefits, as educators can let them run on a virtual machine or personal computer. This can help circumvent some major concerns applicable to other GenAI tools and LLMs (e.g., data protection, lack of control over changes, privacy). Therefore, this study explores the feedback characteristics of the open, lightweight LLM Llama 3.2 (3B). In particular, we investigate the models’ responses to authentic student solutions to introductory programming exercises written in Java. The generated output is qualitatively analyzed to help evaluate the feedback’s quality, content, structure, and other features. The results provide a comprehensive overview of the feedback capabilities and serious shortcomings of this open, small LLM. We further discuss the findings in the context of previous research on LLMs and contribute to benchmarking recently available GenAI tools and their feedback for novice learners of programming. Thereby, this work has implications for educators, learners, and tool developers attempting to utilize all variants of LLMs (including open and small models) to generate formative feedback and support learning

NLP-Enhanced Techniques for Cheating Detection in Virtual Exams: A Comparative Study of String and Semantic Similarity Measures with K-Shingling, Minhashing, LSH, and K-Means
As online learning gains popularity, the issue of cheating becomes a topic of interest in discussions and scientific papers about virtual and distance education. The shift from in-person to online exams has raised many concerns about its potential to make cheating easier. The best way to detect cheating in online exams is to compute the closeness between answers. In this paper, we introduce a new approach based on similarity measure techniques from text mining to analyze answers in order to identify common patterns among academic responses. For this purpose, we have improved the K-Shingling-Minhashing-locality sensitive hashing (LSH) technique by incorporating the K-means clustering step, and then we applied our approach to a use case to efficiently find similar answers in a large dataset. Comparing our results with related works underscores the efficiency and applicability of our method in educational contexts, offering a novel contribution to the field of text similarity detection by highlighting the reliability and consistency of mathematical methods
Hand Gesture Recognition for Virtual Mouse Control
Our work delved into the complexities of real-time hand motion interpretation and fingertip recognition to simulate the functionality of a traditional mouse. We developed a python-based technique that seamlessly translates hand movements into mouse commands by analyzing the angles between fingers and calculating the ratio of the hand’s silhouette to its convex hull. Our methodology was refined to ensure an intuitive and accurate user experience. However, challenges remained in achieving robustness and accuracy in gesture recognition systems in various scenarios, including variations in lighting, hand orientation, and individual human characteristics. These factors had a significant impact on system performance and reliability. To address these challenges, our approach incorporated the algorithms and machine learning models designed to adapt to different conditions. Despite these advances, further research and development were essential to improve the reliability and comprehensiveness of gesture recognition technologies
