In this study, we hypothesize that cases demonstrating exemplary practice in the science classroom can be used as a source for learning content and pedagogical skills that will improve teachers' self-efficacy beliefs. Twelve preservice elementary science teachers are followed as they participate in a case and case method activity illustrating the Grade 7 topic of robotics and fluids. While there was little evidence to show improvements in content knowledge, results indicate that the case acted as a boundary object for brokering between individual experiences and those found in the science teaching community by scaffolding for multiple points of entry, bridging the theory practice gap and offering beginning teachers more immediate access to the community of already practicing teachers.

ABSTRACTThis paper presents an analysis of the conceptualization of massive open online courses (MOOCs) by major influencers in Chinese higher education. Using critical discourse analysis, predominantly from university resources, a map of the discursive construction of MOOCs is presented and interpreted. The centralized orientation of decision making in Chinese higher education is reflected in how MOOCs have been introduced, envisioned, and utilized in China. With the increase of Chinese MOOCs, elite universities are able to capitalize on their comparative advantages, which may be counter to the true intent of MOOCs, which is to raise teaching standards across sectors. This paper serves to illuminate how MOOCs may reinforce the status of elite universities, thereby having the opposite effect to their real intention of democratizing higher education for the masses. The strategy of using MOOCs to improve teaching quality and augment the worldwide reputation of Chinese institutions is central to China’s reinvigorated focus on higher education, which counters the widely held perception, and intention, that MOOCs are vehicles for widening access. 相似文献

This article reports on a six-month telementoring initiative in a Canadian community nursing organization. The way in which Internet technologies may support and augment face-to-face mentorship of health care professionals is a relatively unexplored area of research and was the focus of this project. Participants ( N =22) were all employees of Saint Elizabeth Health Care (SEHC), a community nursing agency servicing 150,000 clients in urban and rural Ontario, Canada. Nurse mentees ( n =11) and nurse-mentors ( n =11) engaged in collaborative discourse in webKnowledge Forum, a second-generation computer-supported intentional learning environment (CSILE). Discussions among all participants were directed at collaborative learning and professional development. Results indicate that mentees contributed and read more notes than mentors and were more likely to engage in threaded discourse with peers. Readership patterns were similar for both groups. Fifty-eight per cent of all nurses reported improved asynchronous communication and problem-solving skills as a result of online collaboration. Seventy-five per cent of all respondents reported a positive professional development experience and 50% of all respondents reported improved clinical practice ability as outcomes of the telementorship program. All reported high satisfaction with the technology. It is concluded that this project facilitated a shift from dyadic mentor-mentee (preceptor-intern) training to communal opportunistic learning and professional development. 相似文献

84 3-month-olds were tested in 3 studies of the acquisition and long-term retention of category-specific information. Infants who were trained with a perceptibly different member of an alphanumeric category on each of 3 days generalized responding to a novel instance of the original training category but not a novel member of a novel category during a 24-hour novelty test. 2 weeks later, when infants displayed no evidence of remembering their prior training experience, categorization was reinstated if a novel exemplar from the original training category was used as the retrieval cue in a memory reactivation procedure. A novel exemplar from a novel category was not an effective retrieval cue. The effectiveness of the category-specific retrieval cue was a function of its physical similarity to the individual exemplars encountered during training, not testing. The background against which the alphanumeric exemplars were displayed during training was not an effective retrieval cue in either the 24-hour novelty test or the memory reactivation procedure, indicating that all invariant stimulus attributes do not contribute equally as category cues. These data are the first to document retention of category-specific information after extended intervals. A popular account of categorization holds that infants abstract invariant features from individual exemplars and form a schema or distinctive memory representation of these shared features against which subsequent exemplars are compared. The present data provide support for a more parsimonious account of categorization, based on the retrieval of information about individual exemplars, that does not require an assumption of prototype formation. 相似文献

Researching the efficacy of online learning: A collaborative effort amongst scholars in Asian open universities 总被引：1，自引：0，他引：1
This article reports on a collaborative effort amongst scholars from ODL institutions across Asia that resulted in an analysis of the status of online learning. Eleven leading open universities participated in this project, each having representatives join the project team. The exchange among team members and data collection was conducted solely online and comprised the following three stages: (1) continuous email exchange; (2) institutional profile survey; and (3) student perception survey of online learning. Altogether, 1906 students returned valid questionnaires. The results reveal an array of methodologies used to design, implement and deliver online learning and include the perceptions of users on the advantages, disadvantages and barriers to learning online from an ODL perspective in Asia. 相似文献

The Open University of Hong Kong (OUHK) offers 199 courses with online features to enhance the distance learning environment. The university has arranged these courses to provide students with greater flexibility in interacting with tutors, classmates, and the content itself. Integral to learner flexibility online is access, valuing computers and online learning, endorsement, and language proficiency. The current investigation attempts to explore these issues by examining the perceptions of OUHK students enrolled in courses with online tutorial supports. The methods of questionnaire survey and semi‐structured interview were employed. Surveyed using multistage stratified sampling technique were 449 OUHK students enrolled in 18 upper level courses (9 English, 9 Chinese) at the OUHK. Forty‐two students were randomly selected for a follow‐up interview. Five major topics were explored including: (1) accessing the Internet; (2) perceptions of technology; (3) rationale for using the Internet in course work; (4) learning strategies used by the tutor online; and (5) perceptions of the online tutorial support. 相似文献

Science-specialist Student-teachers Consider Promoting Technological Design Projects: Contributions of Multi-media Case Methods 总被引：1，自引：0，他引：1

In school science, students often experience simplistic representations of knowledge-building practices in science and technology – which, in reality, are complex, unpredictable and theory-limited. While there are a great variety of reasons (many of which are beyond teachers' direct control), this occurs partly because teachers of science generally have not had such realistic experiences. While student-teachers can develop this kind of meta-scientific literacy in university-based science teacher education programmes, this depends on the extent to which activities are legitimised through close associations with authentic school contexts. In this paper, we report effects on science-specialist student-teachers' conceptions about science and technology, and corresponding priorities for school science, after interacting with a case documentary that depicted students collaborating in development and evaluation of pneumatic-controlled robotic arms. Data, including video footage of student-teachers' interactions with cases and audio recordings of interviews with them and their teacher, indicated that many student-teachers developed more naturalistic perspectives on knowledge development in science and technology and corresponding pedagogical priorities. At the same time, most also recommended an apprenticeship for students, gradually moving them from unrealistic (e.g., following a linear model for technological design) to more realistic (e.g., accommodating flexibility in design, while pointing out such limits to creativity as techno-determinism) problem solving contexts. 相似文献

Long-Term Memory for a Single Infancy Experience 总被引：1，自引：0，他引：1
Children's memory of a single infant experience was evaluated. Children in the experimental groups (N = 16 for 2.5-year-olds; N = 8 for 1.5-year-olds) had participated at 6.5 months in a study of auditory localization where they reached in the light and dark for a sounding object. They were reintroduced to the laboratory and the dark procedure they had experienced on that one occasion either 1 or 2 years previously. The first 5 trials were uninstructed; for the remaining 5 trials, children were instructed to find the sounding object. For half of the older group, a potential reminder of the infant procedure was introduced. The original infant rattle was sounded for 3 sec out of reach in the dark one-half hour prior to test trials. Equal numbers of age-matched inexperienced control subjects were also tested. The older children with infant experience reached and grasped the sounding object significantly more overall, and on instructed trials, than age-matched control children. Experienced 2.5-year-olds were also more likely to remain in the testing situation than children in the control group. The reminder facilitated uninstructed performance of the experienced children. Instructions to reach were helpful to all subjects. We conclude that children remembered aspects of a single experience that occurred when they were 6.5 months of age. 相似文献
