This paper reports on research that took place at Nottingham Trent University (NTU) and Sheffield Hallam University (SHU), United Kingdom, over two years. The project formed the basis of an iterative, interpretive, action research study focussing on a particular set of participants--trainee teachers. The insights gained from the initial cycle fed into planning the second cycle, for which the action plan was modified and the research process repeated (Zuber-Skerritt 1992). The research project focuses on the use of Web 2.0 technology, specifically web logs, (or blogs) with trainee teachers, both during their university programme and during the first year of teaching as full-time newly qualified teachers. The purpose of this research was to add to a developing body of knowledge identifying whether technology used by trainee teachers during their training course can be cascaded into their practice once qualified. Participants from the two collaborating universities were introduced to blogs and blogging during their time at university, and encouraged to use it for themselves, and to also think about how it could be used in their own classrooms when they were teaching. Questionnaires were used to ascertain their thoughts on the use of blogs during training, and these were followed up with interviews with a number of the trainees to determine the cascading of this technology, once they had become newly qualified teachers (NQTs) and were teaching in schools. These interviews explored the reasons for enabling or inhibiting the use of blogs in their teaching in school. This paper presents the findings of the research and discusses the enablers and inhibitors that were identified in the light of current research findings. The research supports the view that developing innovative use of technology in the classroom is complex and experiences during training are not always transferred into practice. (Contains 1 table.)
