Hypothesis testing in students: Sequences,stages, and instructional strategies     

David Moshman  Pat A. Thompson 《科学教学研究杂志》1981,18(4):341-352

Six sequences in the development of hypothesis-testing conceptions are proposed, involving (a) interpretation of the hypothesis; (b) the distinction between using theories and testing theories; (c) the consideration of multiple possibilities; (d) the relation of theory and data; (e) the nature of verification and falsification; and (f) the relation of truth and falsity. An alternative account is then provided involving three global stages: concrete operations, formal operations, and a postformal “metaconstructive”stage. Relative advantages and difficulties of the stage and sequence conceptualizations are discussed. Finally, three families of teaching strategy are distinguished, which emphasize, respectively: (a) social transmission of knowledge; (b) carefully sequenced empirical experience by the student; and (c) self-regulated cognitive activity of the student. It is argued on the basis of Piaget's theory that the last of these plays a crucial role in the construction of such logical reasoning strategies as those involved in testing hypotheses.  相似文献   

Second-order conditioning of the pigeon’s keypeck     

Michael E. Rashotte  Robert W. Griffin  Cheryl L. Sisk 《Learning & behavior》1977,5(1):25-38

Pigeons learned to peck a keylight (S2) when it was paired with a stimulus (S1) that already evoked keypecking. Control procedures showed that S2 acquired control over responding because it was paired with S1 and because S1 had a conditioning history, thereby supporting the claim that S2 was a second-order conditioned stimulus. Second-order conditioning occurred as rapidly when S1 was a keylight as when it was a tone. Test procedures showed that after second-order conditioning, responding to S2 was markedly debilitated by the extinction of responding to S1, indicating that the ability of S2 to evoke a response importantly depends upon the continued ability of S1 to do so. Our demonstration that directed motor action in the pigeon is susceptible to second-order conditioning suggests a new interpretation of conditioned reinforcement in instrumental learning. Our demonstration that the effectiveness of S2 depends upon the continued effectiveness of S1 indicates that S-S associations are formed in this version of the second-order conditioning experiment.  相似文献

This research compares the industry readiness, product development skill level, and overall knowledge gains of students taking an undergraduate research course (treatment) to those who did not (control). This 2‐semester Applied Interdisciplinary Product Development (AIPD) course for sophomores brought together interdisciplinary teams of food science, nutrition, and packaging science students in a hands‐on setting to create healthy food products for children, complete with retail packaging. A Subject Knowledge Assessment (SKA) was used to evaluate the mean percent difference value (MPDV) of food science, nutrition, packaging science, and general product development knowledge gained through the course. SKA results indicated that the MPDV were significantly different (α = 0.05) between the treatment and comparison groups in the overall score and in every subject area score except packaging science. Data from an Exit Questionnaire (EQ) was used for evaluation of attitudes pertaining to product development knowledge and skills, department engagement, and pedagogy. EQ results indicated that mean scores between the treatment and comparison groups were significantly different (α = 0.05) in 7 of the 9 statements on product development knowledge and skills, both statements pertaining to pedagogy, and the statement pertaining to department engagement. Overall, the research project was considered a successful intervention for educating sophomores at the University. Overall, the research project was considered a successful intervention for educating sophomores in the Food, Nutrition and Packaging Science department at Clemson University. The student‐lead teams were held to a greater degree of accountability for their success in terms of education gleaned and value of experience gained as metric for the University and other IFT Accredited programs.  相似文献   

Severed Heads and Compliant Bodies? A speculation about principal identities     

Pat Thomson 《Discourse: Studies in the Cultural Politics of Education》2004,25(1):43-59

When I had to reapply for my own position as principal I felt as if I was facing the prospect of losing a part of myself. Conversations with other women colleagues confirmed that I was not alone in this response. Taking this as my cue, I explore the notion of principal “identification” practices—that is the continuing process of forming a “principal identity”—through personal narrative, a Cartesian metaphor and emerging research evidence. In particular, I focus on how conditions of entrepreneurial governance change a continuing policy commitment to heroic leadership, and how principal and school identities are conflated through accountability regimes, marketing requirements and work intensification. I propose that a study of changing principal identities might fruitfully add to critical leadership and management scholarship, complementing the emergent corpus on emotions in leadership.

Defining 'Early Career' in Research   总被引：1，自引：0，他引：1  

Pat Bazeley 《Higher Education》2003,45(3):257-279

In order to ensure the future of high qualityresearch in some disciplines it may benecessary to provide special consideration inprestigious research funding schemes for earlycareer researchers who will otherwise becomedisenchanted with academic research and leaveit behind in their search for a stable andfruitful future. Milestones in progressionthrough research studies and academic life toestablishment as an academic researcher areoutlined. Within this context, a range ofpotential criteria for determining promisingearly career status are reviewed. Thediscussion leads to derivation of thedefinition of early career which has beenadopted by the Australian Research Council forits prestigious Discovery – Projects grantsscheme.  相似文献

Democracy and School Leadership in England and Denmark   总被引：1，自引：0，他引：1  

Pat Mahony  & Lejf Moos 《British Journal of Educational Studies》1998,46(3):302-317

Evidence will be presented from two projects to support our argument that concepts and associated activities of leadership are shaped by the political contexts in which they are embedded. By comparing the managerialist purposes and definitions of school leadership in England with more democratic orientations in Denmark, we add our voices to the growing concern about the future of democracy in England.  相似文献
