Many aspects of the paper “What if we were in a test tube?: students’ gendered meaning making during a biology lesson about the basic facts of the human genitals” intrigue and warrant further exploration. This forum will focus on two particular areas: (1) An expansion of the companion meanings by examining how they resonate with themes forwarded by other feminist scholars who critiqued biology and reproduction. (2) A proposal of some pedagogical approaches that might provide solutions to de-center the prioritization of heterosexual male genitals and of facts over complexities in science. 相似文献

Studies in laboratory animals have shown that the extinction of a conditioned stimulus, A, is regulated by the associative history of a second stimulus, X, when the two are extinguished in simultaneous compound: An inhibitory X protects A from extinction (Rescorla Learning & Behavior, 31, 124–132, 2003), whereas an excitatory X facilitates, and under some circumstances deepens, the extinction of A (Rescorla Journal of Experimental Psychology: Animal Behavior Processes, 26, 251–260, 2000, Journal of Experimental Psychology: Animal Behavior Processes, 32, 135–144, 2006). In the present study, we used the allergist task to examine whether the extinction of causal judgments in people is similarly regulated by the causal status of co-present stimuli. Experiment 1 showed that a cue trained as a conditioned inhibitor protected a target cue from extinction: The target extinguished in compound with the inhibitor was rated as being more causal of the outcome than was a target extinguished in compound with a control cue lacking inhibitory properties. In contrast, the remaining experiments showed that the extinction of a target cue was regulated by the presence, but not the causal status, of a partner cue: Target cues extinguished in compound were protected from extinction, and no evidence showed that an already extinguished partner conferred more protection (Exp. 2), or that an excitatory partner conferred any less protection (Exps. 2 and 3), or that an excitatory partner deepened the extinction of its already extinguished target. These findings are inconsistent with elemental models that rely on a common error term to explain associative changes in extinction. They are largely, but not completely, consistent with the configural model proposed by Pearce (Psychological Review, 94, 61–73, 1987), which predicts an ordering of levels of protection that was not observed. 相似文献

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

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
