Abstract

Background: Promoting a positive attitude towards teaching statistics and probability has become a shared challenge for teachers’ training today. Objectives: In this study we examined validity and reliability of Attitudes’ Scale towards Probability and its Teaching (ASPT) given by Estrada, Batanero, and Díaz. Design: Following a quantitative methodology. Setting and Participants: The attitudes of a purposive sample of 126 prospective Chilean and Spanish mathematics teachers were analysed using ASPT scale. Data collection and analysis: through an Exploratory Factor Analysis. Results: they were organized into two parts. While the first part focused on the psychometric characteristics of the scale, the second one emphasised on specific attitudes of the sample. Conclusions: The findings revealed a positive attitude towards the scale. It was viewed ASPT to be an instrument with good characteristics to explore attitudinal aspects of teachers.
