Resistance to interference was examined in rats that received a complex negative patterning discrimination in which XA and
XB were followed by food reinforcement and XAB was not. Retention of the discrimination was evident after separate reinforcement
of both A and B (Experiment 3), but not after reinforcement of either AB (Experiments 1 and 3) or XAB (Experiments 2 and 3).
These data suggest that complex negative patterning discriminations are acquired configurally and that the relative similarity
of the original discrimination and subsequent interference trials dictates the final degree of retention observed. 相似文献

Two mechanisms for engaging in critical reflective dialogue are discussed and compared: face-to-face meetings and asynchronous online discussion. The context is an umbrella action research project, with over 20 participants, which aimed to improve practices in online teaching and contribute to the development of graduate attributes. The article compares discussion using the two modes (face-to-face and online) of the nature of and development of problem-solving and other graduate attributes. Face-to-face discussion was wide ranging and quite loosely structured, so divergent aspects of a topic were uncovered. The asynchronous nature of online discussion, however, permitted topics to be explored more thoroughly. The two modes worked well in conjunction with one another, if aspects of face-to-face discussion topics were posted online as discussion threads. The asynchronous online discussions then allowed each thread to be explored in depth, so that collective understanding of a given topic could be enhanced. 相似文献

There has been considerable investment in the use of interactive whiteboard technology in schools in the UK. There is evidence that whilst teachers understand such technology, many do not understand the nature and implications of interactive learning. Observation and analysis of 50 video‐recorded lessons taught by ‘successful’ teachers drawn from mathematics and modern foreign language departments in secondary schools led to the classification of three types of practice representing a spectrum of increasing interactivity. The nature of this good practice was analysed together with criteria for assessing the changes being wrought by technology in approaches to learning and teaching. The investigation concluded that the use of new technology alone cannot lead to enhanced learning. Teachers also need training to develop awareness of the relationship between approaches to interactive learning and conceptual and cognitive development in subject areas. 相似文献

This article describes Mikhail Bakhtin’s 20th century work on dialogue as it may serve one engaged in the teaching as a vocation and existential pursuit rather than as
a job or profession. Dialogue, as theorized by Bakhtin, within the pedagogical real, potentially becomes a mod of being through
which the individual engages in the project of selfhood, a task basic to the human enterprise. For Bakhtin, dialogue was in
part a structure within and through which we come to consciousness and give flesh and meaning to our existence. According
to Bakhtin, the structure of self is dialogical and unfinalizable, meaning that each individual comes to consciousness through
dialogue with some other. From a Bakhtinian perspective, the, selfhood as a dialogical formation constitutes a fundamental
relation by which we much participate without end, making dialogue an unavoidable social activity immersed in language. 相似文献

Pigtailed monkeys were trained on discrimination problems involving objects that had been previously paired with reward, previously paired with nonreward, or objects not associated with any pretraining. In two separate studies, no differences on these various problem formats were observed, but performance improved considerably with practice. These results are contrary to the theories for learning set formation of Spence and Medin. 相似文献
