Assessment in higher education has focused on the performance of individual students. This focus has been a practical as well as an epistemic one: methods of assessment are constrained by the technology of the day, and in the past they required the completion by individuals under controlled conditions of set-piece academic exercises. Recent advances in learning analytics, drawing upon vast sets of digitally stored student activity data, open new practical and epistemic possibilities for assessment, and carry the potential to transform higher education. It is becoming practicable to assess the individual and collective performance of team members working on complex projects that closely simulate the professional contexts that graduates will encounter. In addition to academic knowledge, this authentic assessment can include a diverse range of personal qualities and dispositions that are key to the computer-supported cooperative working of professionals in the knowledge economy. This paper explores the implications of such opportunities for the purpose and practices of assessment in higher education, as universities adapt their institutional missions to address twenty-first century needs. The paper concludes with a strong recommendation for university leaders to deploy analytics to support and evaluate the collaborative learning of students working in realistic contexts.  相似文献

In Experiment 1, male rats were exposed to either aggressive (i.e., alpha) or nonaggressive conspecific colonies and tested 24 h later, with or without alpha odors, for freezing behavior and burying of a wall prod that had been the source of a brief electric shock. The results indicated that prior defeat experience and the presence of alpha odors alone during testing had no significant effects, but the combination of prior defeat and alpha-odor testing significantly decreased burying and increased freezing behavior. In Experiment 2, we examined the effects of noncontact exposure to a cat, as a predatory Stressor, during subsequent prod-shock tests involving the presence or absence of cat odors. Exposure to a cat failed to disrupt later prod burying and did not produce freezing. However, the presence of cat odors during testing significantly reduced the amount of defensive burying,without resulting in an increment in freezing. In Experiment 3, rats were given 1, 5, or 30 inescapable preshocks in the presence of either cat odors or a hedonically neutral citronella odor and were tested 24 h later for prod burying and freezing with or without these odors. Both the cat and the citronella odors resulted in a significant reduction in burying and an increase in freezing for rats given 5 and 30 preshocks and tested in the presence of these respective conditioned odors. For the groups that were given 5 preshocks, preshock and later testing in the presence of cat odors resulted in significantly less prod burying and more freezing than for rats that were preshocked and tested in the presence of citronella. The findings of these three ethoexperimental studies are discussed in terms of the learned-helplessness theory, the stress-coping-fear-defense (SCFD) theory, and the concept of selective CS-US associability.  相似文献

The Behavior Intervention Centres are part of the Houston Independent School District's (HISD) Special Education Department. Their purpose is to provide educational services to elementary and secondary students, aged 3 through 21, who exhibit either severely aggressive or severely withdrawn behaviours. This article describes a formalized follow‐up service considered by the authors to be a critical component of the BIC program.  相似文献

How evident is democracy within education in Japan, and is current practice different from elsewhere? This paper assesses the perception that Japanese political and educational practices are not fully 'democratic'. The first part examines the Japanese perspective on democracy, and then considers democracy and education in Japan. From a school-based study, the second part discusses examples of class practice concerning decision-making. The paper concludes that democracy is deeply rooted in Japanese history, but not in a form that is readily recognisable to Western observers. Consensus has been more significant than voting. The view that the US administration had a strong influence probably reflects policy rhetoric, not the reality in schools. But this rhetoric may have led to a belief that 'democracy' is not an appropriate term within contemporary Japanese education. However, what happens in Japanese classrooms equates with 'democratic' practice elsewhere.  相似文献

In each of two experiments, rats were trained to press the lever in a Skinner box, food reinforcement being available on a variable-interval 60-sec schedule (VI 60). There followed an “exposure phase” for which the levers were removed from the boxes, and then a final test with the levers replaced to assess the effects of the intervening treatment on instrumental responding. Experiment 1 showed that simple exposure to the box reduced the vigor of instrumental performance in comparison with a condition in which food was made available during the exposure phase. Animals which received no exposure treatment also showed a relatively high rate of response. Experiment 2 demonstrated that an exposure treatment in which the occurrence of food is signaled by a light stimulus also leads to a decline in instrumental responding. These results are held to support the notion that associations between the context and the reinforcer serve to energize appetitive instrumental behavior.  相似文献

This paper explores experiences that remained salient in the memories of former participants in three nature-based programs in Colorado, five to forty years after childhood involvement. Interviews with program founders and staff, archival research, and observations of current activities provided an understanding of each program’s history, mission and educational approach. In this context, 18 former participants were interviewed about program experiences that they remembered and program impacts on their environmental identities and academic or career choices. Results were analyzed through the lens of social practice theory, which has significant implications for the design and evaluation of environmental education programs. Results showed that social practice theory is a useful framework for interpreting the development of a social environmental identity, but an ecological identity that forms through direct contact with the natural world is an important complementary concept.  相似文献

This study explores the impact of one-to-one computing on student achievement in Ohio high schools as measured by performance on the Ohio Graduation Test (OGT). The sample included 24 treatment schools that were individually paired with a similar control school. An interrupted time series methodology was deployed to examine OGT data over a period of 5 to 8 years. Overall student performance and content-specific achievement in math, reading, science, social studies, and writing were not significantly affected by the introduction of 1:1 computing. Treatment schools using a netbook device produced the greatest overall change in scores.  相似文献
