Case studies and generalisability - grounded theory and research
in science education
International Journal of Science Education, 22 (5), pp.469-487
Abstract:
'Grounded theory' may be used to bridge between case
studies and large-scale surveys, which enables the strengths of both to be
combined in the same research programme. Starting with detailed in-depth
studies of individual cases, a general model may be constructed through the
key processes of 'theoretical sensitivity', 'theoretical sampling' and 'theoretical
saturation'. Unlike most qualitative methodology, the grounded theory approach
claims to produce testable outcomes: grounded theory is intended to lead
to predictions which may be subject to traditional experimental and statistical
testing. This paper describes one example of the application of a grounded
theory approach to research into the learning of science, and considers the
generalizability of the research results.
