Educational research is not very influential, useful, or well funded. This article explores why and suggests ways that the situation could be improved. Our focus is on the processes that link the development of good ideas and insights, the development of tools and structures for implementation, and the enabling of robust implementation in realistic practice. We suggest that educational research and development should be restructured so as to be more useful to practitioners and to policymakers, allowing the latter to make better-informed, less-speculative decisions that will improve practice more reliably.

An analysis has been made of all available data near threshold for the reactions nN-* KKN in terms of isospin amplitudes. The experiments for different channels are found to be consistent with each other and with the chiral-symmetry-breaking model of Olsson and Turner. The analysis yields values for the KK scattering lengths which are in good agreement with a calculation based on the Weinberg KK interaction corrected for the effects of the/o(975) scalar meson.
