How has Item Response Theory helped solve problems in the development and use of computer-adaptive tests? Do we need to balance item content with computer-adaptive tests? Could we use IRT to evaluate unusual responses to computer-delivered tests? 相似文献

Post-war growth of higher education has attracted the interest of national governments. They are properly concerned with higher education's contribution to economic success and equity, and the efficient and effective use of public funds. They can intervene by means of legislation (which is unwieldy), exhortation (which is ineffective), or funding incentives. Funding councils must operate within a social and political context which determines the balance between planning and the market, central and local direction, public and private funding. They have only four strategies to choose from: deficiency-, formula-, contract-, and core-funding. The first was nearly fatal; the last is the preferred option for the future.
There are two issues: the merging of the two funding councils (PCFC and UFC), and the ending of the binary system. The first could produce a welcome single guiding intelligence for UK higher education, and economies of scale. The second raises the question of the funding of fundamental research. The merging of PCFC and UFC and the reorganisation of research-funding is a two-headed nettle. It must be grasped soon. 相似文献

This paper explores Roger Revelle's activities in oceanography and institution-building during and after the Second World War. In particular, it explores his shift from a wartime acceptance of science serving mission-oriented objectives, to a defence ofthe distinction between basic and applied science. For Revelle, the Federal government, and especially the military, became theguarantor of basic research in oceanography. This understanding led him to privilege military sponsorship over contract research,and the physical over the biological sciences. He drew upon that understanding to construct a unique institutional geography for science in southern California. 相似文献
