Resumen
En la asignatura Probabilidad y Estadística para las carreras de Ingeniería de la Universidad Nacional de La Matanza, Argentina, se observa un elevado número de abandonos y desaprobaciones. Teniendo esto en cuenta, los profesores de esta asignatura empezaron hace algunos años a utilizar una plataforma web de autocorrección automática denominada e-status. Esta plataforma cuenta con el software libre R como motor de cálculo y permite parametrizar problemas para que el alumno pueda resolverlo varias veces, con variaciones. Los alumnos disponen de un repositorio activo de problemas para practicar los contenidos propuestos por sus profesores, obteniendo corrección inmediata de sus resultados.Si bien los resultados obtenidos en publicaciones anteriores de este grupo de investigación mostró una clara incidencia de la práctica en e-status sobre la aprobación del tema, Se produjo la necesidad de acompañar los ejercicios numéricos con otros de tipo conceptual o teórico para favorecer la reflexión y metacognición de los contenidos. Los estudiantes requieren una mayor orientación para el aprendizaje en espacios de e-learning que favorecen el cuestionamiento de sus supuestos conceptuales y su forma de apropiarse de los contenidos. Para tener en cuenta estos aspectos, trabajamos los contenidos de la plataforma y ofrecimos a los alumnos un curso de estrategias metacognitivas.El seguimiento realizado de 2016 a 2018 muestra una mejora académica estadísticamente significativa a favor de quienes utilizan la plataforma. Además, el incremento en el uso de la plataforma es un indicador del valor que le dan los estudiantes y profesores, con un efecto positivo en la aprobación de la asignatura y consecuentemente en la disminución de la deserción.
In the subject Probability and Statistics for Engineering careers at National University of La Matanza, Argentina, a high number of dropouts and disapprovals are observed. Taking this into account, the professors of this subject started some years ago to use an automatic self-correcting web platform called e-status. This platform has the free software R as a calculation engine and allows parameterizing problems so that students can solve it several times, with variations. The students have an active repository of problems to practice the contents proposed by their teachers, obtaining immediate correction of their results. Although the results obtained in previous publications of this research group show a clear incidence of the practice in status on the approval of the subject, it was observed the need to accompany the numerical exercises with others of conceptual or theoretical type to favor reflection and metacognition of the contents. Students require more guidance for learning in e- learning spaces that favor the questioning of their conceptual assumptions and their way of appropriating the contents. To take these aspects into account, we worked on the contents of the platform and offered students a course in metacognitive strategies. The monitoring carried out from 2016 to 2018 shows a statistically significant academic improvement in favor of those who use the platform. Additionally, the increase in the use of the platform is an indicator of the value given by students and teachers to it, with a positive effect on the approval of the subject and consequently on the decrease in dropouts.
