Los recursos tecnológicos en la estadística bidimensional en los textos españoles de bachillerato.

Current curriculums recommend the use of technological resources in the teaching of statistics,due to the help they represent in the calculation and production of graphs, the work with real dataand the learning of several concepts through simulation. In this research, we analyse the differenttechnological resources suggested in high school textbooks for teaching and learning bi-dimensionalstatistics in high school (organization and representation of bi-dimensional data, correlation andregression).The importance of this issue is due to the fact that it extends functional dependence torandom situations and provides students with opportunities to model numerous applications. Onthe other hand, previous research shows many difficulties of understanding and misconceptionson these topics. The researchers analysed sixteen Spanish text books, using content analysis; eightbooks of each of the two modalities that include this topic: “Humanities and Social Sciences” and“Science and Technology”. In these books was analysed the use of technological resources in theproblems and procedures proposed, the references to technological resources in Internet and thecontent of a CD that supplements most of these textbooks. The results suggest a scarce presenceof these resources in the textbooks analysed, and a large variability of the resources described. Thereference to Internet resources is often reduced to didactic units and not to data sets that can beused in projects or simulators to facilitate conceptual understanding. The CD which supplementssome of these textbooks sometimes reproduces the same text which appears in the book or includescollections of traditional exercises; there are few problems and procedures based on technology.Finally, some recommendations for improvement of these texts are presented, considering technologicalresources.
