A Grounded Practical Theory Reconstruction of the Communication Practice of Instructor-facilitated Collegiate Classroom Discussion     

Heidi L. Muller 《Journal of Applied Communication Research》2014,42(3):325-342

Instructor-facilitated collegiate classroom discussion (IFCCD) is a highly valued yet undertheorized instructional practice. Research examining the structure of classroom interaction, scholarship advocating rationales for discussion-based pedagogy, and an investigation of a related interactive classroom communication practice provide an informative backdrop for this study. The data in the study were collected using action-implicative discourse analytic techniques throughout a semester in three classrooms at the same university. Reconstructing the three levels of the practice through grounded practical theory—the problem/dilemma level, the normative situated ideals level, and the talk/discourse techniques level—provides some insight into why in two of these cases of IFCCD, engaged and participatory discussion was accomplished. The shared dilemma of the practice is reconstructed as the problem of engagement in which both individual engagement with curricular content and shared engagement in co-creation of the discussion are valued. The dilemmatic nature of the practice is explored specifically in terms of traditional and nontraditional teacher talk and associated participation structures. Significant similarities and differences across the three cases are found and examined in the reconstructions of instructor situated ideals and third-turn facilitation techniques. Initial conclusions are incorporated in the discussion of discourse-based applications for practitioners interested in facilitating discussion in college classrooms.  相似文献   

On electrets     

Adams Edwin P. 《Journal of The Franklin Institute》1927,204(4):469-486

(I) Evidence has been given that the so-called permanent electrets of Eguchi are not permanent, but that their polarization decays with the time. At room temperatures this decay is too slow to be observed directly; but it is the decay of the polarization that, at least in part, accounts for the presence of the free charges that are always observed. At higher temperatures the results that have been obtained are consistent with the view that the rate of decay of the polarization increases very rapidly with the temperature; so much so that the polarization may be almost completely destroyed at a temperature which is not high enough to cause any appreciable softening of the waxes that form the substance of the electrets.(2) As is to be expected from Lord Kelvin's hypothesis as to the cause of pyro-electricity, these electrets have been shown to possess the pyro-electric property.(3) The piezo-electric effect, which always accompanies the pyro-electric property, has been shown to be exhibited by these electrets.  相似文献

From Policy to Practice: Pupils' Responses to Widening Participation Initiatives     

Arthur Baxter  Jim Tate  Sue Hatt 《Higher Education Quarterly》2007,61(3):266-283

Recent widening participation policies have been subject to a number of criticisms; they focus on aspirations rather than differences in performance; they place less value on the aspirations of the ‘disadvantaged’ comparing them to a middle class norm; they subordinate what was a radical agenda to the demands of the economy and so constrain the available options to young people. Using data from young people who have taken part in Aimhigher initiatives in the South West of England and from teachers who have organised Aimhigher events, this paper will examine to what extent these features of policy are evidenced in the attitudes and aspirations of these pupils. It will argue that the data shows little evidence of pupils positioning themselves as inferior, that young people display instrumental attitudes to education, but that these attitudes relate to policy discourse and practice in complex ways.  相似文献

Application of systems analysis to depository library decision making regarding the use of new technology     

Mary Sue Stephenson  Gary R. Purcell 《Government Information Quarterly》1984,1(3):285-307

This article, the first in a series of four, views the application of systems anal ysis and design as a method of problem solving for documents librarians. Par ticular emphasis is placed on the use of systems analysis as a major, first step in applying computer based technology to problem areas common to U.S. government publication collections. The specific problem areas amenable to the application of this methodology include (1) bibliographic control, (2) col lection development, (3) collection integration, and (4) improved documents reference service. The steps required for its application to these problem areas are described in sequential fashion, and are augumented by actual examples. Several sources of supplementary information are noted for further references.  相似文献
