Interactividad y atención a la diversidad en el aprendizaje de la estadística

Resumo

In this research, a model has been designed, implemented and analyzed to encourage the development of some mathematical competences in Compulsory Secondary Education students when working in an interactive and collaborative teaching and learning environment. Thus, we have analyzed the efficiency of this interactive tutorial system related to the development of some particular mathematical competences, that's to say, those that have to do with learning Statistics. This methodological tool, interactive environment for the learning of Statistics, has activities in whose design and structure has been strongly considered on the one hand the characteristics of our students, and on the other hand the progressive inclusion of aids; also raising different levels of demand based on the activity or problem posed initially. This has been fundamental in order to give response to the educational needs of our students and for getting the basic competences and objectives of the corresponding curriculum. Besides, we have compiled a series of graphics appeared in press from two points of view, first as a fact that it is necessary the study of Statistics in all levels of the educational system since we have found lots of errors, and second, as a means of creation of activities for our students. On the other hand, it has been selected a series of historical examples where statistical terms can be found. These examples have been a means of inspiration for designing activities for our students. Furthermore, we have built some tests to assess our students' statistical competence. The analysis of initial and final tests results shows the methodology used through the different phases of the research has provided a considerable rise of the global results for all the students, included the one with specific educational needs. Besides we have validated the efficiency of our interactive environment comparing the statistical competence achieved by the students that have used it with the competence acquired by other samples of students that have not followed this methodology. Finally, it has been made an analysis about the evolution of our students' errors related to Statistics after working with the interactive environment.
