Foraging on the radial-arm maze: Effects of altering the reward at a target location

Thirsty rats were trained to collect small water rewards from the end of each arm of an eight-arm radial maze. During these training trials and subsequent testing trials, the subjects were allowed to choose a maximum of eight arms. “Preference” for a target maze location was studied by noting when, in the sequence of eight choices, the target was selected. During testing, when one maze location was consistently devoid of water, rats decreased their preference for this arm over trials (Experiment 1). Similarly, rats that learned a saccharin-lithium association demonstrated lower preferences for a maze location that consistently held the conditioned saccharin solution. This was true for animals that received saccharin-lithium conditioning on the maze (Experiment 3A) and for animals conditioned to saccharin in a separate context (Experiment 3B). An increase in preference for a target maze location consistently containing a sweet chocolate milk solution was observed in animals that were water- and food-deprived (Experiment 2). These studies demonstrate that animals will modify their responses toward (preferences for) maze locations that predictably contain an altered reward.     

The challenges of feedback in higher education

Abstract

Assessment feedback is one of the most important components of the learning process. However, student and educator dissatisfaction with feedback practices continues to remain a significant problem in higher education. To better understand the barriers to effective feedback, the present study explores feedback challenges identified by 3807 students and 281 educators from two Australian universities. Open-response data were analysed using an inductively derived coding framework and thematic analysis. The findings reveal three major themes relating to the challenges of feedback from the perspective of students and educators: feedback practices, contextual constraints and individual capacity. In addition to confirming the persistence of many previously reported challenges in the literature, this paper also offers insights into challenges that are particular to feedback, especially relating to the production of useful comments and the perceived hurdles of both student and educator attitudes and capabilities. The findings also highlight the constrained nature of educators’ work, particularly in relation to time. While further research is needed, we propose that feedback needs to be understood as an interaction between practices, context and individuals.     

Positive Youth Development Among Diverse Racial–Ethnic Children: Quality Afterschool Contexts as Developmental Assets

Positive youth development (PYD) deserves more empirical attention, particularly among children of diverse racial–ethnic backgrounds. Given the need among families for monitoring and supervision during out‐of‐school time, community‐based afterschool is a potentially promotive ecological setting. This study explores the quality of afterschool experiences upon PYD. This multimethod study includes over 500 elementary school children in Grades 2–5 (M_age = 8.80, SD = 1.12). The sample comprises of 49% White, 27% African American, 7% Latino, and 17% mixed race/others with 45% free/reduced lunch eligible children. In multilevel models, independently observed quality across time positively impacted competence, connection, caring for all youth, and cultural values for racial–ethnic minority youth. Afterschool fosters PYD, including sociocultural dimensions, when comprised of appropriately structured, supportive, and engaging interactions.     

A Critique of the Existing Research into Small Primary Schools

Major studies carried out in the United Kingdom on small primary schools are drawn upon and evaluated. It is argued that research in this area is flawed for the following reasons: there is no agreed definition of a 'small primary school'; investigations have been biased in their favour as a result of problems in research design and the ways in which data have been analysed; and, finally, there has been a neglect of certain key issues, notably those affecting pupil grouping.     

Consulting Parents to Improve a Child Guidance Service

This paper describes a study undertaken with a group of parents whose children had been referred to the Knowsley Child Guidance Service. A qualitative methodology was used to analyse in-depth interviews with parents. The results led to practical recommendations for the improvement of service delivery. These recommendations had implications for schools and other services involved with parents/carers and children. The survey also provided a base from which to develop a questionnaire for the continuing evaluation of good practice within the child guidance service.     

Discourses and Subjectivities of the Gendered Teacher

In this study, the authors ask the question, 'What does it mean to wear the labels "teacher" and "female"?' Eighteen Master of Arts in Teaching students volunteered to participate in a Gender Issues Seminar at a large US public state university. Their language, recorded through audio-recordings, response journals, and autobiographical webs become the basis for analysis. Applying post-structural feminist theory, the authors identify powerful discourses determining what it means to be 'female' and 'teacher.' The study illustrates how the discourse of teaching as acceptable women's work and the discourse of patriarchy work upon the subjectivity of women as they struggle with what it means to be teacher/woman. The authors then partially deconstruct these discourses, considering implications for teacher educators.     

Defending the Boundaries: Identifying and Countering Threats in a Usenet Newsgroup

This article is an account of a Usenet newsgroup whose participants, in response to a perceived 'invasion' of 'barbarians,' explored and articulated the value of the group, the nature of the crisis facing it, and the strategies available to meet the crisis. The newsgroup facilitated political and personal support for some gay, lesbian, or bisexual men and women. The primary threat to the group was the increasing number of newcomers who were oblivious to established norms, who tended to view access to the group as a commodity, and who attempted to impose 'outside' paradigms on the operations of the group. Defensive strategies involved calling on rhetorical devices (such as flaming or ostracism) or structural resources (such as employers, network operators, or lawsuits). All strategies had the potential to backfire, but rhetorical strategies were less risky, more available, and more community affirming than strategies requiring access to structural resources. Through this account, the article addresses the mutual linkages and dependencies between the social and technical organization of computer-mediated communication (CMC) networks, the community-building activities taking place through those networks, and the social, legal, and economic structures in which those networks are embedded.
