EXPLICACIONES DE CIERTAS ACTITUDES HACIA EL CAMBIO: LAS CONCEPCIONES DE PROFESORES Y PROFESORAS DE MATEMÁTICAS COLOMBIANOS(AS) SOBRE LOS FACTORES DETERMINANTES DE SU PRÁCTICA DE ENSEÑANZA DEL ÁLGEBRA ESCOLAR.

This article arises from a study whose overall purpose was to investigate the relationship between Colombian mathematics teachers' conceptions of beginning algebra and their conceptions of their own teaching practices. The teachers' understandings of their teaching practices were explored with a view to unraveling their conceptions of change in their teaching. Focusing on the perspectives of teachers afforded opportunities that exposed the powerful role that the teachers' conceptions of social/institutional factors of teaching played in their conceptions of their practices. The degree to which they attributed these (external) factors as crucial reasons for what they do in their teaching was the basis of a categorisation of their conceptions of the crucial determinants of their teaching practices into three types. The findings are particularly relevant to our understanding of the stability of mathematics teaching approaches in the Colombian context but have likely implications for a range of international education contexts. Specific implications for the development of the research into teachers' conceptions of mathematics and its teaching, and for teacher education programmes are presented. [ABSTRACT FROM AUTHOR]
