This paper reviews university-level efforts to improve understanding of anthropogenic global climate change (AGCC) through curricula that enable student scientific inquiry. We examined 152 refereed publications and proceedings from academic conferences and selected 26 cases of inquiry learning that overcome specific challenges to AGCC teaching. This review identifies both the strengths and weaknesses of each of these case studies. It is the first to go beyond examining the impact of specific inquiry instructional approaches to offer a synthesis of cases. We find that inquiry teaching can succeed by concretising scientific processes, providing access to global data and evidence, imparting critical and higher order thinking about AGCC science/policy and contextualising learning with places and scientific facts. We recommend educational researchers and scientists collaborate to create and refine curricula that utilise geospatial technologies, climate models and communication technologies to bring students into contact with scientists, climate data and authentic AGCC research processes. Many available science education technologies and curricula also require further research to maximise trade-offs between implementation and training costs and their educational value. 相似文献

Concern about academic dishonesty has led to studies designed to explore its nature, prevalence, and causes. Nevertheless, to date there has been little empirical work designed to test the efficacy of measures to reduce cheating behavior. Many authors agree that there should be institutional statements about academic dishonesty that give definitions and state the penalties for cheating. The purpose of this study was to examine the efficacy of such statements in terms of their influence on perceived severity and perceived incidence of plagiarism in undergraduates. We found that having the students read a carefully worded statement about plagiarism was an effective way to change the perceptions of how seriously plagiarism breaches academic guidelines. Our data further suggest that providing guidance about avoiding plagiarism that encourages students to take a more serious view of the issue is likely to have positive effects on future behavior. 相似文献

Language and Williams Syndrome: How Intact Is "Intact"? 总被引:2,自引:0,他引:2

It has been claimed that Williams syndrome (WS), a rare neurodevelopmental disorder, is characterized by serious cognitive deficits alongside intact language. The syndrome is often used as a prime example of the modularity of an innate faculty for morphosyntactic rules. We challenge this claim and hypothesize that morphosyntax, although surprisingly good given WS level of mental retardation, is by no means intact. We make an initial test of this hypothesis through an analysis of the receptive language of a group of English-speaking WS individuals on a standardized morphosyntactic test. We then present an experimental study of expressive language that examines grammatical gender assignment in French-speaking WS patients. Despite a Verbal Mental Age selected to be higher than the chronological age of the young control group, these people with WS continue even in adulthood to show clear-cut deficits in their production of an aspect of morphosyntax that normal children acquire effortlessly very early. The results of the 2 studies, one focusing on receptive language and the other on expressive language, challenge the notion that comprehension and use of morphosyntactic rules in WS individuals are intact. The within-domain dissociations regarding the use of grammatical gender assignment across several sentence elements and their difficulties in understanding embedded sentences—two quintessentially linguistic skills—suggest that we must rethink the notion of spared, modular, language capacities in Williams syndrome. We conclude that WS language follows a different path to normal acquisition and may turn out to be more like second language learning. 相似文献

Sociocognitive theory [Bandura, A. (1986). Social foundations of thought and action: A social cognitive theory. Englewood Cliffs, NJ: Prentice Hall; Bandura, A. (1989). Human agency in social cognitive theory. American Psychologist, 44, 1175–1184. doi:10.1037/0003-066x.44.9.1175; Bandura, A. (1991). Social cognitive theory of self-regulation. Organizational Behavior and Human Decision Processes, 50, 248–287. doi:10.1016/0749-5978(91)90022-L] accords high importance to the mechanisms of human agency and how they are exercised through self-efficacy. In this paper, we developed and validated the McGill Self-Efficacy For Inquiry Engagement (McSELFIE) instrument with undergraduate students in natural science disciplines. We defined inquiry engagement as carrying out the practices of science (POS) that are supported by students’ personality characteristics (SPCs) and that result in achieving inquiry-learning outcomes (ILOs). Based on these theoretical perspectives, the McSELFIE is a 60-item, learner-focused survey that addresses three components that are theoretically important for engaging in scientific inquiry: (a) SPCs, (b) ILOs, and (c) POS. Evidence for construct and content validity were obtained by using experts’ judgments and confirmatory factor analysis with a sample of 110 undergraduate students enrolled in science disciplines. Internal consistency of the factors and instrument was also examined. The McSELFIE instrument is a reliable and valid instrument for measuring science undergraduate students’ self-efficacy for inquiry engagement. Matched pairs analyses were conducted among the instruments’ factors. Students reported the highest self-efficacy for openness, applying knowledge, and carrying out investigations. Students reported the lowest self-efficacy for extraversion, understanding metacognitive knowledge, and planning investigations. Theoretical and practical implications are discussed. 相似文献

Background: Practical work is widely seen as a necessary part of a good physics education, but convincing evidence that it impacts positively on pupils’ learning is scarce. Recent work suggests the use of talk and discussion might hold the key to making practical work more educationally productive.Purpose: The research question that this study aims to answer is: Can the use of targeted discussion improve learning through practical work?Sample: The study took place in a medium-sized (700-pupil, Years 7–13 (ages 11–18)) mixed-gender independent (fee-paying) day school in southern England. It is academically selective and public examination results are above the national average. The activities were carried out with three teaching groups (n = 73) with a fourth being used occasionally for comparison purposes (giving n = 97).Design and methods: Pupils were given a number of practical tasks – some from the usual scheme of work, some devised for this project – and given specific time to discuss with a partner the various aspects of the practical such as predictions, devising methods, problem-solving, conclusions or explanations of phenomena. Questionnaires and booklets were used to gather pupil responses. Some audio recording and analysis of pupil-pupil discussion was also done.Results: There was evidence from booklets pupils filled in during the practical that prescribing the use of discussion at various points in a practical task led to improved outcomes, particularly on the more cognitively challenging tasks. In particular, discussion was seen to turn incorrect responses into correct ones much more frequently than the reverse. In a later exam, pupils who had participated in the discussion activities performed better than a control group on questions which directly related to practical concepts, but performed similarly on the remaining exam questions.Conclusion: Evidence gathered suggests a more nuanced pattern than that reflected in previous literature: that discussion during practical work can impact positively on pupils’ understanding of ideas related to practical work, but does not necessarily have a positive impact on their wider understanding. 相似文献

AbstractContract cheating happens when students outsource their assessed work to a third party. One approach that has been suggested for improving contract cheating detection is comparing students’ assignment submissions with their previous work, the rationale being that changes in style may indicate a piece of work has been written by somebody else. This approach is time consuming, but recent advances in machine learning and natural language processing suggest that it may be well suited to computerization. We trialed an early alpha version of Turnitin’s Authorship Investigate tool, which compares students’ submissions against their previous work. Twenty-four experienced markers from five units of study were asked to make decisions about the presence of contract cheating in bundles of 20 student assignments, which included 14 legitimate assignments and six purchased from contract cheating sites. We asked markers to determine if each assignment was contract cheating, then provided them with an Authorship Investigate report and let them change their decision. Marker accuracy at detecting contract cheating increased significantly, from 48% to 59% after using the report, with no significant difference in false positives. These findings suggest that software may be an effective component of institutional strategies to address contract cheating. 相似文献

The COVID‐19 pandemic has undoubtedly affected every corner of the world in 2020. It has also emphasized the importance of managing supply chain risk and developing an agile supply chain. Supply chain management instructors will likely want to introduce risk management concepts and strategies into their courses to raise their students' sensitivity to the impact of supply chain disruptions. Unfortunately there is currently a dearth of coverage of supply chain disruptions and risk management in the major supply chain management text books as well as in the broader library of supply chain management pedagogical research publications. To help to close this gap in the literature for instructors, we have developed a reading and set of related discussion questions and exercises that detail the causes of the shortage in toilet paper during the pandemic and short‐ and long‐term strategies to make the supply chain more resilient in the future. By focusing on a disruption students likely experienced first‐hand, they can develop a more nuanced understanding of the complexity and interconnectedness of supply chain functions in providing products and services to customers. 相似文献

Medical and healthcare practice is likely to see fundamental changes in the future that will require a different approach to the way in which we educate, train, and assess the next generation of healthcare professionals. The anatomical sciences will need to be part of that challenge so they continue to play a full role in preparing students with the knowledge and ever increasingly the skills and competencies that will contribute to the fundamentals of their future capacity to practice effectively. Although there have been significant advances in anatomical science pedagogy, by reviewing learning and assessment in an apparently unrelated field, provides an opportunity to bring a different perspective and enable appropriate challenge of the current approaches in anatomy. Design learning has had to continually reimagine itself in response to the shifting landscape in design practice and the threats associated with technology and societal change. Design learning has also long used a student-centric active pedagogy and allied authentic assessment methods and, therefore, provides an ideal case study to help inform future changes required in anatomical learning and assessment. 相似文献
