This action research project developed a portfolio-based learning syst
em, based around a 'log diary', with the trainers and general practiti
oner registrars of one training region in the UK. For those that found
benefit from the system, the diary became an important way of holding
all the events of a training year together; a way of looking back, in
order to view the progress made, and looking forward, to view potenti
al learning needs. Such portfolios were not found to be effective form
al assessment mechanisms because the threat of assessment influenced t
he type of material collected. The enthusiasm of trainers was crucial
in encouraging use of the model. The action research process was funda
mental in stimulating exploration of ideas on reflective learning. The
re remains some resistance to the idea of reflective writing, and in t
his context, portfolios may be one educational tool for use by some, b
ut which may not be universally applicable. Their development and impl
ementation requires considerable local support through facilitation.
