Measuring academic performance is vital in higher education, where it plays a fundamental role beyond simple grading. Therefore, this article on student performance in Mathematics II at the Universidad Nacional Experimental del Táchira (UNET) is of great relevance, since it is considered a key indicator of academic success for a university student. Performance should be analyzed from various perspectives, including systemic and operational factors affecting the quality of education. Where evaluation, as a methodical and scientific process, provides the data required for the study of it and plays a fundamental role in understanding mathematical learning. The research has a quantitative and descriptive approach, using data from grades obtained by students in four academic periods in 2024. A statistical analysis is performed that includes central trend and scatter measures, as well as an analysis of variance (ANOVA) to compare ratings between periods. In addition, performance, dropout and failure indicators are calculated to assess students' academic performance. The results show that the average grade is close to the minimum pass mark of five points, indicating a performance which is hardly acceptable. The rate of return was above 62% in all periods, but dropout and reprobate rates were worrying, especially in 2024-0, where reprobates reached 29%. The variance analysis shows significant differences in average ratings between periods, highlighting 2024-3 as the most successful with an average of 5.26 points. In conclusion, the study underlines the need to identify areas of improvement in the teaching processes of learning in mathematics II, considering the regular average as well as high drop-out and failure rates; to promote the efficiency and quality of education at UNET.
Since antiquity, human beings have strived to access water by constructing structures to transport it from distant sources to central locations. Today, this remains a challenge, especially when it comes to supplying small, remote communities outside large centralized systems. In developing countries in particular, rural aqueducts are fundamental elements in water management. However, most of these systems are managed by communities with limited access to technical training, materials, technology, and resources in general, which hinders sound decision-making and prevents the establishment of sustainable processes. In this context, sustainability is linked to the ability of these systems to maintain certain quality conditions in technical, environmental, social, institutional, and economic aspects over time. This qualitative research focuses on the technical dimension of the service level in rural aqueducts and its impact on their sustainability. To this end, a documentary review was carried out to establish the components inherent to the mentioned dimension and their corresponding indicators. The selected components were: water source, intake structure, screening unit, adduction and conduction line, grit chamber, disinfection unit, storage tank, and distribution network. The selection principle was based on the structural units typically present in these systems. The technical components allow for the consolidation of an efficient and high-quality water supply. Proper design, the use of appropriate materials, and continuous maintenance ensure that the aqueduct operates safely and efficiently. This clearly contributes to the sustainability of the systems, as their integrity fundamentally depends on the physical components, which have a decisive influence on all dimensions of the system and constitute the essence of its operation.
Nowadays, the combination of information technologies and artificial intelligence (AI) has become a fundamental element for the transformation and competitiveness of organizations, especially in the telecommunications sector. These technologies not only optimize internal processes but also enable organizations to quickly adapt to current market demands and improve the customer experience within the telecommunications field. In this regard, this study analyzed the impact of information technologies on artificial intelligence (AI) within the company Digitel, Authorized Agent Espacio Digital, C.A., located in Acarigua, Portuguesa state. It was also possible to measure how these technologies improve operational efficiency and customer service. To this end, a quantitative approach was used through a non-experimental and descriptive design, applying surveys to 15 employees of the company. The results indicated that 87% of the respondents stated that software platforms and AI tools are used, which has contributed to an 80% decrease in response time to customer requests and a 67% increase in customer satisfaction. However, 60% of employees considered that the company lacks the necessary resources to implement new AI tools, which could limit its potential. Additionally, 67% of the workers reported that improvements in AI-related processes have been suggested in the past six months. In conclusion, the research showed that, although Digitel has integrated advanced technologies that have optimized its operations and improved customer service, it still faces challenges in maximizing its impact, suggesting the need to invest in resources and staff training to strengthen the use of AI in the future.
Introducción: Este artículo presenta el desarrollo de un planificador para la superación de obstáculos por parte de robots móviles, implementado en MATLAB. Dicho planificador fue integrado como un módulo dentro de la arquitectura del robot Lázaro, que ahora puede superar obstáculos formados por diferentes inclinaciones, mientras se evalúa cuantitativamente la navegabilidad mediante índices de estabilidad al vuelco y deslizamiento. Metodología: El desarrollo de este planificador incluyó varias fases metodológicas: la definición de los requerimientos del sistema, la estructuración y programación del planificador en MATLAB, y la creación de un módulo de interacción con el usuario. Este último permite ingresar la información geométrica del obstáculo y observar los resultados a través de animaciones y gráficas, evaluando la factibilidad de la tarea antes de su ejecución real. Resultados: Una vez incorporado este módulo en la arquitectura del robot, se realizaron pruebas utilizando simulación dinámica y ensayos en entornos reales. Los resultados demostraron la efectividad del sistema propuesto, generando consignas de movimiento precisas que permitieron al robot superar diversos obstáculos. Conclusiones: La relevancia del sistema radica en su compatibilidad con la arquitectura establecida y su capacidad de integrarse como una maniobra compleja dentro del robot Lázaro.
La motivación de los estudiantes universitarios hacia la escritura creativa constituye un desafío recurrente en el ámbito educativo, especialmente cuando las actividades se perciben como poco dinámicas o desvinculadas de sus intereses. En este contexto, la gamificación ha sido propuesta como una estrategia pedagógica orientada a integrar elementos lúdicos en procesos formativos tradicionales. El objetivo de esta investigación fue analizar las percepciones de estudiantes universitarios sobre la influencia de la gamificación en su motivación intrínseca y extrínseca hacia la escritura creativa. El estudio se desarrolló desde un enfoque cuantitativo, con un diseño descriptivo y no experimental. La muestra estuvo conformada por 100 estudiantes universitarios de segundo año que cursaban la asignatura Escritura Creativa II. La recolección de datos se realizó mediante un cuestionario estructurado con escala tipo Likert, diseñado para medir dimensiones asociadas a la motivación intrínseca y a la motivación extrínseca. El análisis de los datos se efectuó mediante estadística descriptiva. Los resultados muestran que una proporción considerable de los estudiantes manifestó percepciones favorables respecto al uso de elementos gamificados, particularmente en relación con el disfrute del proceso creativo, la visualización del progreso y la claridad de objetivos. No obstante, también se observó variabilidad en las respuestas, lo que indica que no todos los elementos de la gamificación son valorados de la misma manera por los participantes. Los hallazgos aportan evidencias descriptivas relevantes para la reflexión pedagógica en contextos universitarios específicos, reconociendo las limitaciones metodológicas del estudio.
