Abstract (English): Virtual reality is part of the set of haptic technologies that allow the user to interact with an artificial scenario, different from the real world but very similar to it. Within the field of education, it promotes active and dynamic learning with immersive experiences. The goal of this study was to assess the usability of an object in VR format for oscilloscope instruction. We created a virtual physics lab environment in version 1.0. The methodology has a quantitative, descriptive approach. Brooke (1996) designed the System Usability Scale (SUS), which collected data from experts in both technology and physics, totaling 42 participants. We obtained Cronbach's alpha and McDonald's omega indexes with values of 0.924 and 0.901, respectively. The results reveal that the virtual reality (VR) resource received an assessment of 72.58, corresponding to a percentile between 65 and 69, across 500 previous studies by various authors on the SUS. This indicates that the created object has a good acceptance range, being valued as very good and suitable for use in teaching. [ABSTRACT FROM AUTHOR]
Abstract (Spanish): La realidad virtual forma parte del conjunto de tecnologías hápticas que permiten al usuario interactuar con un escenario artificial, distintos al mundo real, pero muy parecido a él. Dentro del campo de la educación, promueve aprendizajes activos y dinámicos, con experiencias inmersivas. El objetivo de este estudio fue evaluar la usabilidad de un objeto en formato de RV para la enseñanza del osciloscopio. Se creó un ambiente virtual de un laboratorio de Física, versión 1.0. La metodología tiene un enfoque cuantitativo, de corte descriptivo. Los datos se recogieron mediante la escala de usabilidad del sistema (SUS, por sus siglas en inglés), diseñada por Brooke (1996), que fue aplicada a expertos, tanto en el área de tecnología como de Física, para un total de 42 participantes. Se obtuvieron los índices de Alfa de Cronbach y Omega de McDonald con valores de 0.924 y 0.901, respectivamente. Los resultados obtenidos reflejan que el recurso elaborado en formato de Realidad Virtual (RV), obtuvo una valoración de 72.58, para un percentil entre 65 y 69, dentro de un abanico de 500 estudios realizados previamente, por diversos autores, en lo referente a la SUS. Esto indica que el objeto creado tiene un buen rango de aceptación, siendo valorado como muy bueno y adecuado para su utilización en la enseñanza. [ABSTRACT FROM AUTHOR]
