For many years the profession has acknowledged a schism between theori
es taught in the classroom and the practice of clinicians. This tends
to arise from beliefs that knowledge which has been generalized (forma
lized) can be readily transferred to informal settings (practice). Whi
lst apprehension of formalized knowledge is crucial to professional de
velopment, a mediator is necessary to demonstrate its relevance to pra
ctice. A variety of solutions have been offered which all have value b
ut without effective social support fail to resolve the problem. Findi
ngs from a longitudinal study investigating the professional developme
nt of pre-registration nursing students indicate the importance of spo
nsorship by a member of clinical staff and participation in legitimate
peripheral activities. In the absence of effective sponsorship, stude
nts found it difficult to participate in clinical activities or to lea
rn. As a result, their professional development during placements beca
me stunted with subsequent implications for their professional future.
Questions concerned with this phenomena were explored using documenta
ry evidence supplied by research participants, observations of their p
ractice and focused interviews throughout their programme. Sociocultur
al or activity theories of human learning offer some attractive explan
ations. One strategy is scaffolding which takes place within sponsored
nursing activities and builds on the important concept of the Zone of
Proximal Development (ZPD), where speech becomes a tool to mediate le
arning and development. As a diagnostic tool, scaffolding enables both
supervisor and learner to recognize knowledge-in-waiting and knowledg
e-in-use and hence learning need, thus stimulating opportunities for f
urther learning and professional development beneficial to both learne
r and supervisor. It provides a means for theory and practice to becom
e integrated.
