University science students' experiences of investigative project work and their images of science

In this paper we consider the ways in which students' activities during project work are influenced by their images of science, e.g. their views about the purposes of science, the nature of scientific knowledge and the role of social processes in scientific activity. We also investigate the kinds of project activities which promote the development of students' images of science. We draw on case studies of 11 science students' experiences of investigative project work in their final year at university. For one of these students naive views about the epistemology of science constrain her project activities. We suggest that the concept of 'epistemic demand' may help in anticipating difficulties that students might have during project work. We also find that students' images of science are developed as a result of messages communicated both implicitly and explicitly through project work.     

Sources of differential participation rates in school science: the impact of curriculum reform

School science courses have widely varying participation rates across a range of student characteristics. One of the stated aims of the 2006 Key Stage 4 science curriculum reforms in England was to improve social mobility and inclusion. To encourage students to study more science, this reform was followed by the introduction in 2008 of an entitlement to study the three separate sciences at Key Stage 4 for the more highly attaining students. This paper uses longitudinal national data over a five‐year period to investigate the extent and change of participation across science courses at KS4, focusing on student gender and socio‐economic status. It finds that whilst there is some evidence of a move towards a more equitable gender balance for some courses, there is as yet little evidence of substantial change in differential participation rates by socio‐economic status.

Undergraduate science students' images of science

This article describes views about the nature of science held by a small sample of science students in their final year at the university. In a longitudinal interview study, 11 students were asked questions about the nature of science during the time they were involved in project work. Statements about the nature of science were characterized and coded using a framework drawing on aspects of the epistemology and sociology of science. The framework in this study has three distinct areas: the relationship between data and knowledge claims, the nature of lines of scientific enquiry, and science as a social activity. The students in our sample tended to see knowledge claims as resting solely on empirical grounds, although some students mentioned social factors as also being important. Many of the students showed significant development in their understanding of how lines of scientific enquiry are influenced by theoretical developments within a discipline, over the 5–8 month period of their project work. Issues relating to scientists working as a community were underrepresented in the students' discussions about science. Individual students drew upon a range of views about the nature of science, depending on the scientific context being discussed. © 1999 John Wiley & Sons, Inc. J Res Sci Teach 36: 201–219, 1999
