Item type:Publication, New Highly Portable Simulator (SECMA) Based on Virtual Reality for Teaching Essential Skills in Minimally Invasive Surgeries<jats:p>This study presents a new minimal access surgery training system, SECMA, and its constructive validation to determine its usefulness for training basic laparoscopic skills. SECMA is an affordable, highly portable, mobile virtual reality training tool for laparoscopic techniques that integrates the Oculus Quest with a mechanical interface for surgeon simulation of forceps using the hand controllers of these devices. It allows the execution of structured activities (supported by virtual scenarios simulating operating rooms developed in Unity), performance evaluation, and real-time data capture. Two experiments were carried out: 1) coordination; and 2) capture and transport, with a total of 21 individuals divided into two groups: a novice group (inexperienced) of 10 participants and an expert group (>100 endoscopic procedures) of 11 participants. Total task time score, right-hand speed, path length, and other metrics from several consecutive runs on the simulator were compared between experts and novices. Data automatically recorded by SECMA during the experiments were analyzed using hypothesis tests, linear regressions, analysis of variance, principal component analysis, and machine learning-supervised classifiers. In the experiments, the experts scored significantly better than the novices in all the parameters used. The tasks evaluated discriminated between the skills of experienced and novice surgeons, giving the first indication of construct validity for SECMA. </jats:p>Scopus© Citations 2 11 - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Facilitando el aprendizaje de trigonometría a través de una interfaz tangibleEn educación matemática, estudios evidencian dificultades y desafíos en la enseñanza-aprendizaje de trigonometría en educación secundaria y superior, donde no se estimula al estudiante a obtener un entendimiento conceptual profundo de los conceptos. Considerando su relevancia para diversas disciplinas, es necesario implementar nuevos acercamientos a su enseñanza, donde se privilegie un rol activo del estudiante en su propio aprendizaje. Diversos estudios demuestran que la incorporación de tecnologías digitales influyen positivamente aprendizaje de los alumnos, sin embargo, la mayoría de las tecnologías existentes responden al paradigma de interacción tradicional con un computador, donde no se considera el uso del cuerpo y de los múltiples sentidos. Las Interfaces Tangibles (TUI) en cambio, pueden albergar interacciones corporales, brindando directo tributo a la teoría de la Cognición Corporal. Sin embargo existe un vacío en la aplicación de TUI para la educación de trigonometría. Esta investigación consistió en diseñar y validar una interfaz tangible para la enseñanza-aprendizaje de trigonometría inicial. La interfaz alberga una experiencia de aprendizaje que privilegia la exploración, el uso de la intuición, y fomenta el aprendizaje colaborativo. Se realizó un Pre-Test diagnóstico con 119 estudiantes para determinar conocimientos previos dando un rendimiento promedio de 29.1%. Luego de dos intervenciones con la interfaz propuesta, los resultados de un Post-Test muestran un incremento del rendimiento en un 37.1%, lo que valida la efectividad pedagógica de la interfaz y experiencia pedagógica para el aprendizaje de conceptos básicos de trigonometría.7 - Some of the metrics are blocked by yourconsent settings
