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, focussing 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.
