    New technologies offer unprecedented opportunities to enhance classroom education, especially in practical subjects like physics, where experiments can be controlled via mobile devices. This facilitates both theoretical and practical learning. This study assesses the impact of using dedicated mobile devices in educational settings compared to traditional teaching methods. The application allows students to view educational information on an M5Stack Core2 device that also includes an electromagnet. We use the Student Evaluation of Educational Quality (SEEQ) to gather feedback and evaluate various aspects of the learning experience. Results indicate significant improvements in learning, enthusiasm, organization, group interaction, individual relationships, and breadth of device usage. Evaluations show that device-assisted classes outperform traditional classes in most categories, highlighting the benefits of integrating technology into education. The findings emphasize the importance of adapting teaching methods to enhance the overall quality of education and student engagement using dedicated mobile devices.

    This study explores the most effective method for impact measurement in laser shooting ranges, crucial for security training, accident prevention, and cost reduction. It utilizes video surveillance and image processing algorithms in Python to accurately determine laser impact locations. The research found that employing a single target per silhouette is most efficient, minimizing errors to ±1 impact and enabling heat map generation for feedback. The combination of video surveillance and image processing significantly enhances safety and reduces costs by providing real-time data. The findings advocate for the single target approach due to its precision and the comprehensive insights gained from heat maps, maintaining accuracy within a two-hit margin.

    This study assesses the effectiveness of Global Navigation Satellite Systems (GNSS) in Ecuador, a country situated on the equator, where unique challenges include elevated ionospheric activity and increased solar radiation. It focuses on the accuracy of major satellite navigation systems such as GPS, Glonass, and Galileo in various environments, from open fields to urban areas with dense building coverage. Using a satellite communication module and a data logger capturing information every second, the study provides a detailed comparison of these systems. The findings indicate that a combination of GPS and Glonass significantly enhances accuracy, reducing errors to less than 20 cm, which is crucial for high-precision applications in the equatorial region. This outcome is consistent with and expands the understanding of satellite navigation performance across different Andean landscapes, highlighting the need for tailored approaches in both urban and rural settings within the equatorial context. In summary, the research reaffirms the transformative role of geopositioning and GNSS in global navigation and emphasizes the potential for improving GNSS accuracy in the equatorial region. It contributes significantly to ongoing efforts to optimize geopositioning systems, ensuring their effectiveness in diverse geographical and environmental conditions, as exemplified in the Andean regions of Ecuador.
