El propósito de la investigación es determinar, si las estrategias de aprendizaje influyeron en la participación y rendimiento del estudiantado de una asignatura de la ciencia del suelo para la modalidad a distancia. Se utilizó la participación y calificaciones de 783 estudiantes de una asignatura de gestión ambiental de una Universidad en el sur del Ecuador. Se organizaron los datos en cuatro periodos comprendidos entre el 2012 y 2018 y se analizaron con estadística descriptiva (medias y frecuencias), tomando en cuenta las estrategias aplicadas en cada periodo, como foros, chats, cuestionarios, trabajos y evaluaciones. Las estrategias sincrónicas y asincrónicas utilizadas influyen en la participación del estudiantado, pero no siempre en su rendimiento; además, el mayor número de actividades enviadas no siempre resulta provechoso; por ello, es clave priorizar y clarificar las actividades que se envíen al estudiantado, con una adecuada planificación y explicación de ellas. Las características únicas de la ciencia del suelo, sumadas al desafío de la enseñanza en modalidad a distancia, constituyen un verdadero reto por lo que continuar investigando los aspectos de la educación de esta ciencia, contribuirá a mejorar el rendimiento académico del estudiantado.
Urban flooding is a major problem in many coastal cities. The rapidly shifting patterns of land use and demographic increase are making conventional approaches to stormwater management fail. In developing countries such as Ecuador, a lack of monitoring, financial constraints and absence of proper policies exacerbate flooding problems. This work assesses the implementation of two Low Impact Development strategies (LIDs), namely, green streets and rain barrels, as nature-based solutions to mitigate flooding problems. The use of the “Stormwater Management Model” (SWMM) helped to contrast the new approach with the current state of the drainage system, including normal and extreme scenarios. With an implementation of 1.4% (19.5 ha) of the total area with LIDs, the reduction of runoff for short events (200 min) is around 20%, and for extreme events (within 24 h) is around 19% in comparison to the conventional approach. Flooded nodes were reduced to 27% for short events, and to 4% for extreme events. The peak flooding system had a reduction to 22% for short events and 15% for extreme events. These highlights help to increase city resilience, and authorities and stakeholders should engage in climate actions to reduce flood risks complementing drainage operations with nature-based solutions. Moreover, calibrated results in this article serve to increase awareness among municipal authorities regarding the importance of maintaining flooding records to improve modelling results for decision-makings processes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
