Blocking of first- and second-order autoshaping in pigeons

In Experiment 1, the development of autoshaped pecking to a keylight signaling food was blocked if the keylight was presented only in conjunction with another stimulus already established as a signal for food, even though the blocking stimulus (either an overhead light or a train of clicks) never elicited pecking itself. In Experiment 2, pigeons came to peck a white keylight which signaled the presentation of a red keylight which had earlier been established as a first-order signal for food, but this second-order autoshaping was blocked if the white keylight was presented only in conjunction with the houselight or clicker which had previously signaled the presentation of the first-order stimulus. Second-order autoshaping was thus blocked in the same way as was first-order autoshaping.     

Intensification of punishment effects through exposure to prolonged, fixed-duration shocks: The role of shock cues as a stimulus for fear

Three experiments tested the hypotheses that (1) the onsets of prolonged, fixed-duration treatment shocks (shock treatment, or ST) serve as cues for fear conditioning to the ongoing painful effects of these stimuli, and (2) this acquired fear transfers to and influences shock-motivated test performances in predictable ways. Experiments 1 and 2 involved spaced post-ST presentations of very brief shocks (a presumed analogue of the onsets of treatment shocks) as a means of extinguishing the fear putatively associated with shock cues. This procedure reduced defecation by ST subjects over blocks of extinction sessions and nullified the punishment intensification effect that was otherwise shown to be a consequence of ST. As a further test of the shock-cue hypothesis, Experiment 3 involved relatively massed presentations of these brief shocks prior to ST in a latent-inhibition procedure (Lubow, 1973). This briefshock regimen also nullified the ST punishment intensification effect but did not impair the transituational transfer of contextual fear. In contrast, the group that was given the same brief shock regimen following ST showed enhancement of the punishment effect. With respect to current theoretical accounts of ST effects, these data were most consistent with notions that rely on an acquired-fear construct.     

Social Use of the School Library: the colonisation and regulation of educational space

The existing literature on school libraries has been dominated by a view of them as ‘learning laboratories’ which should allow students opportunities for reading and conducting research into small scale projects. From this perspective, resource issues and helping students become knowledgeable users of library facilities are the major problems facing school librarians. This study breaks from the traditional research by focusing on the social use of the school library. Data are used from two case‐studies of school libraries to analyse student colonisation and teacher regulation of library space, and the processes by which students come to associate or dissociate themselves from using the library during the school day. The paper concludes by arguing that social factors form, an integral part of the context in which school libraries stand or fall as arenas which facilitate student learning, and that the spatial dimensions of social interaction should become central to analyses of educational differentiation.     

Preservice teachers’ views of global citizenship and implications for global citizenship education

Global citizenship (GC) is becoming increasingly significant as a desirable graduate attribute in the context of increasing globalisation and cultural diversity. However, both the means and ends of GC education are influenced by a divergent range of conceptualizations. The aim of this research project was to investigate preservice teachers’ understandings of global citizenship, with a particular focus on cultural diversity. Pre-service teachers (PSTs) participated in interviews, and findings indicated that they were uncertain about the idea of global citizenship, sought harmony and a desire for sameness in culturally diverse relationships, and held ethnocentric, paternalistic and salvationist views about the ‘Other’. Drawing on these findings, we present a framework incorporating technicist, humanistic and postcritical conceptions as a tool for analysis of GCE approaches, their means and ends.     

Teacher Consultation to Enhance Implementation of School-Based Restorative Justice

ABSTRACT

Restorative justice (RJ) is an alternative approach to school discipline that has been gaining recognition in the public and academic spheres as a way to engage students who misbehave in school. RJ has promise to address racial/ethnic, gender, and disability disproportionality in school discipline. One aspect of school-based RJ that has received almost no attention in the literature is the professional development and ongoing support of teachers in schools using RJ. This article provides a review of extant literature on school-based RJ, teacher training, and consultation methods. Integrating the empirical literature on school consultation and teacher professional development, we argue that schools should implement a multitiered model of professional development to build teacher competency in RJ, specifically including the use of targeted teacher consultation. The proposed model is complementary to an RJ framework, systematic, and capable of evaluation; future research is needed to evaluate its effectiveness in practice.     

Gender Effects in School Subject Preferences: a research note

Rankings of liking for nine curriculum subjects were obtained from 93 middle school pupils aged 11‐13 years, who also completed the Children's Sex Role Inventory. Statistically significant gender differences in the rankings of English and humanities were found, which were both preferred by girls, and for physical education (PE) and science, which were preferred by boys. Some statistically significant associations between subject rankings and sex typing measures also emerged. Higher rankings of music and humanities were associated with higher Femininity scores, while higher rankings for PE were associated with lower Femininity scores. The only significant association with Masculinity was for English, where higher rankings were associated with lower Masculinity. No significant associations with Masculinity or Femininity were found for science, a traditionally male‐stereotyped curriculum area. Associations found between the rankings of the different subjects indicated a tendency for pupils to prefer either more academic or more practical subjects, but there was no indication from the limited data available on their performance that this could be related to their academic ability. The implications of these preliminary findings for future investigations are discussed.     

Improving the quality and effectiveness of computer-mediated instruction through usability evaluations

Brigham Young University's Center for Instructional Design (CID) creates online courses and multimedia instructional applications for university faculty. This paper asserts that including usability testing as a part of evaluation improves the quality and effectiveness of computer‐mediated instruction. The paper describes the fundamental purpose and functions of usability testing, and also distinguishes between different forms of evaluation: accessibility, quality assurance (QA), usability and implementation. Through a detailed case study, we describe how usability testing improved the quality of a computer‐based chemistry course and facilitated a clearer analysis of the learning effectiveness of this course.
