We analyze the graphs produced by 207 prospective primary school teachers when comparing data collected by them in a statistical project. These graphs are classified according to their correctness, and the type of error in case of incorrect graph. The influence of using computers on the errors produced is also analyzed. Results show the prospective teachers’ difficulties in building statistical graphs, in spite that they will have to teach these graphs, since many of them shared errors reported in previous researches with children.

The aim of this study was to analyze the presentation of regression in Spanish school textbooks directed to Social Sciences students. In a sample of eight textbooks we analyzed the problem-fields and suggested procedures, as well as the associated concepts, which are classified according to the way they are introduced and the properties associated to them. Our results suggest that these textbooks mostly reduce regression to lineal regression, present many properties at an operational level without deep discussion of their meaning, and there is a great variety between the textbooks. Some suggestions to improve the presentation of this topic are included.

This study was aimed to evaluate the accuracy and strategies used in the estimation of association between potential factors and associated risks when data are presented in 2x2 tables. A sample of 414 undergraduate Psychology students from three different Spanish universities was given three different tasks (direct and inverse association and perfect independence) where they had to estimate such association. Most participants judged association in the task where there was perfect independence, but the data contradicted the students’ previous expectations. The estimation of association was consistent with the perception of association and the accuracy of estimates increased with correct strategies. Our participants performed worse than secondary school students in a previous study (Batanero et al., 1996) and we found no difference in the three participating universities. We classify the students’ strategies in the tasks in levels of complexity and explain the incorrect strategies usi...

In this work we analyze the activities proposed and the semiotic complexity levels in the statistical graphs included in two series of Chilean primary education textbooks using content analysis. The most common activities related to these graphs in these textbooks are performing computations, building graphs and using the graphs as examples. The most common complexity level was level 3 (representing a data distribution). These results also show (with smaller frequency) a varied type of activity and higher semiotic levels with increasing age of students.

ABSTRACT En este trabajo concebimos el sentido estadístico como unión de la cultura y razonamiento estadístico. Se describen las ideas estadísticas fundamentales como componentes de la cultura estadística y los componentes del razonamiento estadístico. También se sugiere que el desarrollo efectivo en los estudiantes se favorece especialmente con una enseñanza basada en investigaciones y proyectos que permite dotar de sentido a los diversos objetos estadísticos e involucra a los estudiantes en el ciclo de investigación y modos de razonamiento estadístico, desarrollando su espíritu crítico e iniciativa personal.

The ubiquity of randomness and the consequent need to understand random phenomena in order to make adequate decisions led many countries to include probability throughout the curricula from primary education to University level. This need was also recognized by the mathematicians who developed the probability theory. This is a relatively young field, and is not free of controversies, which are also reflected in the lack of agreement on a common definition of randomness. Psychological and didactical research, suggest widespread misconceptions and misperceptions of randomness; however, these results have not always been taken into account in teaching, where randomness is considered a transparent concept.

Resumen En la actualidad encontramos diferentes criterios sobre la enseñanza de la probabilidad en la educación primaria. Mientras países como Uruguay o España la incluyen desde los primeros niveles, en otros se retrasa incluso a la educación secundaria. En esta conferencia analizamos las razones que justifican la importancia de una introducción temprana de la probabilidad, resumimos algunas investigaciones que indican que el niño tiene un razonamiento intuitivo correcto en situaciones aleatorias sencillas y sugerimos algunos principios metodológicos y actividades para facilitar la introducción de la probabilidad a los niños. Se finaliza con algunas sugerencias para avanzar en la enseñanza e investigación sobre el tema.

The use of computers in the teaching of statistics is receiving increasing attention from teachers and researchers (Shaughnessy, Garfield, & Greer, 1996). The introduction of computers is encouraged in different curricula, such as in the "Standards" of the National Council of Teachers of Mathematics (1989) and the "Diseño Curricular Base" in Spain (M.E.C., 1989), not only to extend what mathematics is taught, but also to affect how that mathematics is learned. However, there is still scarce research reported concerning the introduction of computers for teaching statistical concepts. This paper presents the results of an experimental research project that investigated the effects of a computer-based teaching environment on students' understanding of statistical association. The experimental sample consisted of nineteen, 20 year-old university students who were enrolled in their first year course on exploratory data analysis and descriptive statistics. The tea...

The objective of this didactical — mathematical analysis is to provide criteria of selection of the said problems, directed to guiding the student's learning towards the adequate meanings of the statistical notions and
