La evaluación y seguimiento del estudiante de forma telemática: el proyecto Cuestionarios

En la mayor parte de las ciencias, los ejercicios practicos son la mejor manera de adquirir y evaluar, tanto conocimientos cientificos como las habilidades y competencias necesarias para su aplicacion. Es un entrenamiento que, como en el mundo del deporte, resulta imprescindible y mejora el rendimiento. La resolucion de problemas exige una gran dedicacion del profesorado y, en este aspecto, la utilizacion de cuestionarios on-line puede ser de gran ayuda. Sin embargo, este tipo de cuestionarios tambien presentan una dificultad, que es el esfuerzo inicial necesario. Para reducir esta dificultad se planteo la elaboracion de una base de datos de cuestiones y un protocolo de exportacion.

Enseñar química y motivar con un click / Teaching Chemistry and Motivating with a Click!

ABSTRACT The use of electronic response systems or “clickers” is a popular way to engage students and create an active-learning environment, especially within large courses of general subjects for first-year undergraduates. The present work examines with detail the methodology, the tasks and the results obtained respect to the students’ learning, participation, and engagement in the classroom. In general, students perceived that clickers provided a significant enhancement to their learning, and teachers obtained real-time feed-back of how the concepts are assimilated or not by the students in order to quickly introduce improvements in their teaching.RESUMENEl uso de sistemas electrónicos de…

A brief review on the contribution to the knowledge of the difficulties and misconceptions in understanding the chemical equilibrium.

The existence and persistence of errors in the understanding of chemical equilibrium denotes student"s difficulties in learning and also in teaching methodologies. The knowledge of these difficulties, in depth, can help teachers to try to overcome them. This work is a review together with new contributions on the chemical equilibrium misconceptions analyzed by a group of university and high school teachers. On the one hand, we pretend to collect some of most common difficulties that students, from high school and university, show in re lation to chemical equilibrium and Le Chatelier's Principle application. On the other hand, we also intend to analyze the possible causes and even, ocasional…
