Abstract

La mayoría de las instituciones de educación superior, al menos en Colombia, se enfrentan a un problema claramente evidenciado, el bajo nivel de conocimiento en ciencias básicas de los estudiantes admitidos, especialmente en matemáticas. Como alternativa para abordar esta problemática en este artículo se expone el uso de un ambiente virtual con contenido en esa área de conocimiento específica y con una característica particular: la ludificación como estrategia didáctica. Se presenta además una validación de dicha propuesta mediante un curso de pre-cálculo en la Universidad Nacional de Colombia. Las conclusiones, luego de un experimento con 2263 estudiantes, es que aquellos que hicieron uso del ambiente virtual ludificado mostraron en promedio un incremento en su desempeño académico y en el porcentaje de aprobación, al tiempo que una disminución en el porcentaje de abandono. Most higher education institutions, at least in Colombia, face a clearly demonstrated problem, the low knowledge level in basic sciences of the admitted students, particularly in mathematics. As an alternative to address this issue, this paper presents the use of a virtual environment with content of that specific knowledge domain and with a particular feature: the gamification as didactic strategy. A validation of such a proposal is also presented through a pre-calculus course in the National University of Colombia. The conclusions, after an experiment with 2263 students, were that those who used the ludified virtual environment showed in average an increase in their academic performance an approval percentage, as well as a reduction in the dropout percentage.

Abstract

Adaptation is a desirable feature in on-line courses which allows for the consideration of students particular characteristics and needs. However, it is not common for teachers to embrace technologies related to this feature. This phenomenon may be mainly attributed to: a) unawareness of appropriate authoring tools, and/or b) resistance to their use. Regarding this panorama, this research has two purposes. The first purpose is to present a web platform to create adaptive on-line courses that considers three adaptive functionalities: curriculum sequencing, content presentation and assessment. The second purpose is to present a validation for such platform with real users, more specifically, 51 teachers of K-12. The obtained results show that even if there was general distrust while using the platform, there was also an overall interest in rely on a tool that grants teachers in providing an individualized learning experience.

Abstract

Learning objects (LOs) repositories are important in building educational content and should allow search, retrieval and composition processes to be successfully developed to reach educational goals. However, such processes require so much time-consuming and not always provide the desired results. Thus, the aim of this paper is to propose a model for the semiautomatic composition of LOs, which are automatically recovered from open repositories. For the development of model, various text similarity measures are discussed, while for calibration and validation some comparison experiments were performed using the results obtained by teachers. Experimental results show that when using a value of k (number of LOs selected) of at least 3, the percentage of similarities between the model and such made by experts exceeds 75%. To conclude, it can be established that the model proposed allows teachers to save time and effort for LOs selection by performing a pre-filter process. [ABSTRACT FROM AUTHOR]
