In this paper we present a methodology for describing adaptive educational game environments and a model that supports the environment design process. These environments combine the advantages of educational games with those derived from the adaptation. The proposed methodology allows the specification of educational methods that can be used for the game… (More)
The classification of f-tilings was inspired in Stewart Robertson's work , " Isometric Foldings of Riemannian Manifolds " and was initiated by Ana Breda , where a complete classification of all monohedral f-tilings of the Riemannian sphere S 2 was done. Here we shall classify, up to a spherical isometry, the class of all dihedral f-tilings of S 2… (More)
We classify, up to an isomorphism, the class of all dihedral f-tilings of S 2 , whose prototiles are a spherical triangle and a spherical rhombus. The equiangular case was considered and classified in Breda and Santos (2004). Here we complete the classification considering the case of non-equiangular rhombi, see Tab. 1 and Fig. 24.
We present Adaptive Bayes, an adaptive incremental version of Na-ïve Bayes, to model a prediction task based on learning styles in the context of an Adaptive Hypermedia Educational System. Since the student's preferences can change over time, this task is related with a problem known as concept drift in the machine learning community. For this class of… (More)
AbstrAct This chapter presents an adaptive predictive model for a student modeling prediction task in the context of an adaptive educational hypermedia system (AEHS). The task, that consists in determining what kind of learning resources are more appropriate to a particular learning style, presents two issues that are critical. The first is related to the… (More)
We classify the group of symmetries of all dihedral folding tilings by spherical triangles and spherical parallelograms, obtained in ,  and . The transitivity classes of isogonality and isohedrality are also determined, see Table 3.1.
The classification of all dihedral triangular f-tilings of the Riemannian sphere S 2 whose prototiles are an equilateral triangle and an isosceles triangle and the identification of their symmetry groups are given. We also determine their classes of isogonality and isohedrality.
