Un sistema tangible para el aprendizaje de álgebra relacional

Las interfaces tangibles de usuario (TUIs) son aquellas en donde el usuario interactúa con un sistema digital a través de la manipulación directa de objetos físicos (tokens), ligados directamente a cierta funcionalidad/datos dentro del sistema, por lo que su manipulación afecta el comportamiento del...

description Las interfaces tangibles de usuario (TUIs) son aquellas en donde el usuario interactúa con un sistema digital a través de la manipulación directa de objetos físicos (tokens), ligados directamente a cierta funcionalidad/datos dentro del sistema, por lo que su manipulación afecta el comportamiento del sistema. Este artículo presenta TanQuery, un sistema tangible para ayudar en el proceso de aprendizaje de Algebra Relacional. TanQuery incorpora componentes de detección y seguimiento de tokens, para analizar y ejecutar árboles de consulta. El sistema fue probado por estudiantes universitarios y, como se puede observar por los resultados obtenidos, ellos encontraron útil y agradable este tipo de interfaz.

Tokens are directly linked to a certain data/functionality within the system, so manipulation of these objects affects the system behavior. This paper introduces TanQuery, a tangible system to support the process of learning Relational Algebra. TanQuery incorporates components to detect and track tokens, and to analyze and execute query trees. The system was tested by university students, and obtained results allowed to observe and analyze that students found this type of interface useful and pleasant.application/pdfText/htmlengspaUniversidad Autónoma de Bucaramanga UNABhttps://revistas.unab.edu.co/index.php/rcc/article/view/3228/2791Https://revistas.unab.edu.co/index.php/rcc/article/view/3228/2905/*ref*/H.
