The “complex reality” of research capacity development in mathematics education in Southern African development community countries

This paper explores how an aid-funded Ph.D.-programme in mathematics education instituted in some Southern African Development Community countries measures up to issues related to research capacity development projects. The research capacity development programme is described and reflected against mutual benefit, relevance, sustainability and prioritization of the location of project funding expenditure—some of the constructs in the discourse on research capacity development initiatives. It is found that the benefits of the programme are indeed mutual; the outcomes regarding relevance and sustainability are more uncertain and the location of expenditure of the funding is not overtly in favour of the donor country.     

What are the Earth and the heavenly bodies like? A study of objectual conceptions among Norwegian deaf and hearing pupils

This study addresses deaf pupils' conceptions of phenomena, that can be directly observed, of the Earth and sky. In the study deaf pupils aged 7, 9, 11, and 17 years were interviewed. A control group of 9-year-old Norwegian pupils with normal hearing was also interviewed. The results show that the young deaf children have conceptions that are remarkably like the scientifically accepted ones, when their age is taken into account, while this is not the case for the oldest groups. Four out of five deaf 7-year-olds, for example, thought the Earth was spherical, not flat; while only five out of eight deaf 17-year-olds thought the same for shapes of the heavenly bodies. Possible reasons for this are discussed. The results also indicate that the shapes of the signs representing objects may affect deaf people's conceptions of those objects.     

An investigation of Zimbabwe high school chemistry students' laboratory work–based images of the nature of science

This study investigates the proximal and distal images of the nature of science (NOS) that A‐level students develop from their participation in chemistry laboratory work. We also explored the nature of the interactions among the students' proximal and distal images of the NOS and students' participation in laboratory work. Students' views of the NOS and the nature of their chemistry laboratory work were elicited through students' responses to an open‐ended questionnaire and semistructured interviews. The results suggest that students build some understandings of the NOS from their participation in laboratory work. Students' proximal NOS understandings appear to build into and interact with their understandings of the nature and practice of professional science. This interaction appears to be mediated by the nature of instruction. It is posited that each student's conceptual ecological system is replete with interactions, which govern attenuation of proximal understandings into distal images. Methodologically, the study illustrates how students' laboratory work–based proximal and distal images of the NOS can be identified and extracted through analyzing and interpreting their responses to protocols. Implications for A‐level Chemistry instruction and curriculum development are raised. © 2006 Wiley Periodicals, Inc. J Res Sci Teach 43: 127–149, 2006
