Learning from and responding to students' questions: The authoritative and dialogic tension

In this study we present an analysis of classroom interactions initiated by students' wonderment questions. Our interest in such events arises from their potential to stimulate active intellectual engagement in classrooms, which can impact upon the subsequent development of the classroom discourse. In investigating this issue we shall address the following research question: How do student questions impact upon the teaching explanatory structure and modify the form of the ongoing classroom discourse, in selected science lessons? From data collected in a Brazilian secondary school we have selected three classroom episodes, with large differences in both the context in which the student's question emerges and in the communicative approach developed in response to it. The analysis, based on the framework proposed by Mortimer and Scott [Mortimer and Scott (2003). Meaning making in secondary science classrooms. Maidenhead: Open University Press], shows that questions made by students are important in providing feedback from students to the teacher, enabling adjustments to the teaching explanatory structure. These adjustments sometimes occur smoothly, at other times with major changes to the features of the classroom discourse, and elsewhere with misunderstanding and disagreement. The data also suggest the need to consider students' intentions and their active participation in the negotiation of both the content and structure of classroom discourse. © 2009 Wiley Periodicals, Inc.

Generalization of causal efficacy judgments after evaluative learning

In three experiments, we examined the effect of response-outcome relations on human ratings of causal efficacy and demonstrated that such efficacy ratings transfer to novel situations through derived stimulus relations. Causal efficacy ratings were higher, and probability of an outcome given a response was lower, for a differential reinforcement of high rate schedule than for either a differential reinforcement of low rate schedule (Experiment 1) or a variable interval schedule (Experiment 2). In Experiment 3, we employed schedules that were equated for outcome probability and noted that ratings of causal efficacy and the rate of response were higher on a variable ratio than on a variable interval schedule. For participants in all three experiments, causal efficacy ratings transferred to the stimulus present during each schedule and generalized to novel stimuli through derived relations. The results corroborate the view that schedules are a determinant of both response rates and causal efficacy ratings. In addition, the novel demonstration of a mechanism of generalization of these ratings via derived relations has clinical implications.     

Reviewing the Teaching and Learning of Children with Special Educational Needs: Enabling Whole School Responsibility

Neil Morris, Learning Support Co-ordinator, and Phil Parker, Learning Support Manger, at Colmers Farm School, use 'The four Ps of policy' (Palmer, Redfern & Smith, 1994) to review their own practice in the development of the monitoring and evaluation measures of their school's SEN (Special Educational Needs) provision. They outline their commitment to inclusive education, and analyse the ways in which the strategy of 'Subject Department SEN Reviews' focuses upon teaching and learning styles.     

Instrumental responding by rats on free-operant schedules with components that schedule response-dependent reinforcer omission: Implications for optimization theories

In two experiments, we assessed whether rats optimize the number of reinforcers per response. In Experiment 1, one group of rats was trained to leverpress for food reinforcement on a simple variable-interval (VI) 60-sec schedule. For another group, a negative fixed-ratio component was imposed on the VI schedule to produce a conjoint contingency in which reinforcement became available on the VI schedule but was omitted when the ratio criterion was satisfied. In Experiment 2, one group of rats responded on a VI schedule and also received response-independent food. For another group, responding above a certain rate canceled the response-independent food. Despite the negative contingency experienced by the groups in Experiments 1 and 2, responding was maintained at a level at which the number of obtained reinforcers was reduced substantially below the maximum number possible. In addition, in both experiments, the groups that experienced the negative contingency responded at a lower rate than did a yoked control group that experienced the same frequency of reinforcement but lacked the negative component. These results demonstrate that although rats do not optimize their behavior with respect to reinforcement, they are nevertheless sensitive to some aspect of the instrumental contingency in operation.     

Openness and reciprocity: Indigenous community requirements for hosting university students*

ABSTRACT

Although there is a substantial literature critical of the colonising discourses of higher education in both teaching and learning and research, there has been relatively little commentary about work integrated learning (WIL) from an Indigenous perspective. Currently, the higher education discourse of WIL is dominated by a teaching and learning perspective, which focuses almost entirely on the benefits to the student and/or the educational institution. This leaves the Indigenous community experience invisible and continues to reinforce a neo-colonial relationship between higher education providers and Indigenous people. This article reports the findings of a study undertaken in partnership with the Aboriginal community of Cherbourg in Queensland, Australia, which sought to understand the community experience of students undertaking WIL within Cherbourg. Twenty yarns, undertaken by a research assistant employed from the community, provided the basis for identifying key meanings and requirements of the community in their hosting of higher education students. The recent experience of students by the community was found to be positive with reciprocity, openness and practical benefit over time being central concerns. The study concludes that WIL with Indigenous agencies and communities requires decolonising, temporal and relational frames to be employed in the process of negotiating the purpose and processes of higher education student engagement.
