This paper describes trends detected in first year engineering students' attitudes towards the use of technology in teaching and learning mathematics through opinions gathered in a survey about attitudes designed for this purpose. We describe the process followed to establish categories for the attitudes towards the use of technology evidenced by the students in their answers. The results indicate a trend of positive attitudes. [ABSTRACT FROM AUTHOR]

In this paper we present some reflections on the application of the technique of content analysis in the study of historical texts in mathematics. This work is based on a study conducted in 2009 on the treatment of the metric system in mathematics texts in Spain in which a selection of texts published in the second half of the nineteen century was analyzed. The study provided the identification of three stages that characterize the texts used for the dissemination of new Spanish weights and measures in the selected period. [ABSTRACT FROM AUTHOR]
