In this paper we report upon a first empirical exploration of the relative efficiency of innovation development by product users vs. product producers. In a study of over 50 years of product innovation in the whitewater kayaking field, we find users in aggregate were approximately 3× more efficient at developing important kayaking product innovations than were producers in aggregate. We speculate that this result is driven by what we term “efficiencies of scope” in problem-solving. These can favor an aggregation of many user innovators, each spending a little, over fewer producer innovators benefitting from higher economies of scale in product development. We also note that the present study explores only one initial point on what is likely to be a complex efficiency landscape.  相似文献

This study aimed to assess the impact of an entire academic teacher development programme at a Midwestern masters comprehensive university in the United States over a period of five years by examining changes in teaching and student outcomes of nine randomly selected programme participants. Researchers analysed syllabi, course evaluations, grade distributions, programme activity reports, interviews and vita, and concluded that the centre’s impact was greatest on tenure-track faculty who struggled with their teaching. Far more useful to future improvement, however, were the insights gained from reflection on study methods, the researchers’ emotional responses to their findings, their struggle to make sense of the data and grappling with the definition of ‘impact’. In this paper, the researchers share useful lessons learned and illustrate the difficulties inherent in evaluating academic development programmes, with a view to qualifying recommendations currently prevailing in the literature.  相似文献

In this paper we explore newly qualified New Zealand secondary teachers’ varied accounts of induction. We claim that multiple interpretations of objectives for induction programs are a significant source of this variation. With reference to an activity system framework, we identify four primary objects of induction that were represented in the induction accounts as follows: ‘orientation to learning about the context’, ‘fitting into the school’, ‘completing registration requirements’, and ‘becoming a professional inquirer’. Whilst teachers would be expected to experience all of these objects within their induction experiences, the balance and emphases of these objects within programs varied considerably.  相似文献
