Three experiments examined the effect of response?Coutcome contingencies on human ratings of causal efficacy and demonstrated that such ratings transfer to novel situations through derived stimulus relations. Efficacy ratings generally followed the delta probability rule when positive response-outcome contingencies were employed (Experiment 1) and when some outcomes were not contingent on participants?? responses (Experiment 2). Experiment 3 employed a negative response?Coutcome contingency and manipulated performance expectancies in the task. All three groups overestimated their causal efficacy ratings. A learned helplessness effect was observed when the response?Coutcomes were uncontrollable and in the high-expectancy group when participants?? performance in the task was worse than they had expected. In all experiments, ratings transferred to a stimulus presented during the task and often generalized to novel stimuli through derived relations. These results corroborate the view that outcome probability is a determinant of causal efficacy ratings and that schedules can be employed as UCS in procedures that share characteristics of evaluative conditioning procedures.  相似文献

Evidencing student achievement of standards is a growing imperative worldwide. Key stakeholders (including current and prospective students, government, regulators and employers) want confidence that threshold learning standards in an accounting degree have been assured. Australia’s new higher education regulatory environment requires that student achievements are benchmarked against intended programme learning outcomes, guided by published disciplinary standards and a national qualifications framework, and against other higher education providers. Here, we report on a process involving academics from 10 universities, aided by professional practitioners, to establish and equip assessors to reliably assure threshold learning standards in accounting that are nationally comparable. Importantly, we are learning more about how standards are interpreted. Based on the premise that meaning is constructed from tacit experiences, social interactions and intentional reflection on explicit information, we report outcomes of three multi-part calibration interventions, situated around judgements of the quality of the written communication skills exhibited in student work and their related assessment tasks. Qualitative data from 30 participants in the calibration process suggest that they perceive that the process both assists them both in developing a shared understanding of the accounting threshold learning standards and in the redesign of assessment tasks to more validly assess the threshold learning standards.  相似文献

Metric scale is an important concept taught as part of science curricula across different countries. This study explored metric and relative (body-length) scale concepts of inservice (N?=?92) and preservice (N?=?134) teachers from Austria, and Taiwan, and their concepts were compared with those of teachers from the USA. Participants completed three assessments: the Scale Anchoring Objects (SAO), Scale of Objects Questionnaire (SOQ), and a subsample of participants were interviewed with the Learning Scale Interview. A Rasch analysis was conducted with the SAO and SOQ and results showed that the Rasch model held for these assessments, indicating that there is an underlying common dimension to understanding scale. Further analyses showed that accuracy of knowledge of scale measured by the SAO and SOQ was not related to professional experience. There were significant differences in teachers’ accuracy of scale concepts by nationality. This was true for both metric and body-length SAO assessments. Post hoc comparisons showed that the Austrian and Taiwanese participants were significantly more accurate than the US sample on the SAO and SOQ. The Austrian participants scored significantly higher than the US and the Taiwanese participants. The results of the interviews showed that the Taiwanese experienced teacher participants were more likely to report learning size and scale through in-school experiences than the Austrian or the US participants. US teachers reported learning size and scale most often through participating in hobbies and sports, Taiwanese teachers reported learning scale through sports and reading, and Austrian teachers most often noted that they learned about scale through travel.  相似文献

While a solid understanding of science content knowledge is important in developing expertise in science teaching, it is not necessarily a sufficient condition to teach science effectively in elementary schools. Teachers need to have the ability to transform their knowledge into forms learnable by students. Based on this perspective, the current study explored how science content knowledge was pedagogically transformed in Korean elementary classrooms. Data sources included video-recorded science lessons of five elementary teachers in a metropolitan city of Korea. The analysis of the data revealed that the Korean teachers often engaged in transforming science content knowledge by means of different semiotic modes, including language, pictures, materials, actions, and their complex combinations. Further, their representations of scientific knowledge were in diverse forms, such as personifications, analogies, quiz questions, pictorial models, diagrams, animations, real-life examples, hand demonstrations, videos, flash tools, and songs-and-dances. Future research involving a wider range of participants, such as students, content specialists, and teachers with weak and strong content understanding, was suggested to confirm the findings of this study and find more various ways of pedagogical transformation of science subject matter knowledge.  相似文献

The purpose of this article is to provide an overview of the nature of models and their uses in the science classroom based on a theoretical review of literature. The ideas that science philosophers and science education researchers have in common about models and modelling are scrutinised according to five subtopics: meanings of a model, purposes of modelling, multiplicity of scientific models, change in scientific models and uses of models in the science classroom. First, a model can be defined as a representation of a target and serves as a ‘bridge’ connecting a theory and a phenomenon. Second, a model plays the roles of describing, explaining and predicting natural phenomena and communicating scientific ideas to others. Third, multiple models can be developed in science because scientists may have different ideas about what a target looks like and how it works and because there are a variety of semiotic resources available for constructing models. Fourth, scientific models are tested both empirically and conceptually and change along with the process of developing scientific knowledge. Fifth, in the science classroom, not only teachers but also students can take advantage of models as they are engaged in diverse modelling activities. The overview presented in this article can be used to educate science teachers and encourage them to utilise scientific models appropriately in their classrooms.  相似文献

Team sport apologia are rooted in the ethic of the sport world. Sport figures defend their characters when their conduct appears to the fans to be inconsistent with that ethic. Sport personalities not only attempt to “repair” their public image, but they also reassure fans that they are committed to their teams and the ethic of their sport. They express sorrow for offending others, assert a desire to play the game, and ignore situational detail that could undermine their apologies.  相似文献
