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 unravelling 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 the teachers 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.

Increasing numbers of children are being born through egg donation and thus do not share a genetic relationship with their mother. Parent–infant relationship quality was examined in 85 egg donation families and a comparison group of 65 in vitro fertilization families (infant M = 11 months). Standardized interview and observational measures were used to assess mother–infant and father–infant relationship quality at the representational and behavioral levels. Few differences were found between family types in parents’ representations of the parent–infant relationship. Differences were found between family types in the observational assessment of mother–infant relationship quality, indicating less optimal interactions in egg donation families. Findings suggest that egg donation families function well in infancy overall, but there may be subtle yet meaningful differences in mother–infant interaction quality. 相似文献

We describe an activity that introduces students to population modelling, enables them to use estimates obtained from a sample to infer back to the population, and understands how the findings are translatable via penguins and their poo! 相似文献
