This study investigates relationships between self-efficacy, self-regulated learning strategy use and academic performance. Participants were 96 undergraduate students working on projects with three subtasks (idea generation task, methodical task and data collection) in a blended learning environment. Task self-efficacy was measured with self-reports administered during each subtask. Learning strategies were assessed by counting each instance of strategy use as it occurred in peer-to-peer conversations typed into a computer software system. Results showed that for each subtask, learners with higher task self-efficacy had higher task performance. Those who used more learning strategies on each subtask also had higher performance. In turn, high performance was associated with high self-efficacy on subsequent subtasks. Surprisingly, results showed that task self-efficacy and learning strategy use were not significantly related during any subtask. Overall, results imply that task self-efficacy, learning strategy use and past performance are important predictors of task performance. 相似文献

In this paper, we demonstrate for the first time the technique to using microfluidics to fabricate tissue engineering scaffolds with uniform pore sizes. We investigate both the bubble generation of the microfluidic device and the application of foam as a tissue engineering scaffold. Our microfluidic device consists of two concentric tapered channels, which are made by micropipettes. Nitrogen gas and aqueous alginate solution with Pluronic® F127 surfactant are pumped through the inner and the outer channels, respectively. We observe rich dynamic patterns of bubbles encapsulated in the liquid droplets. The size of the bubble depends linearly on the gas pressure and inversely on the liquid flow rate. In addition, monodisperse bubbles self-assemble into crystalline structures. The liquid crystalline foams are further processed into open-cell solid foams. The novel foam gel was used as a scaffold to culture chondrocytes. 相似文献

Retailing, in the context of developing economies, has been claimed to be a social practice. A review of fictional literature from the ethno-linguistic region of Bengal may enhance our understanding of the social and cultural history of independent retailing. The evidence from social sciences shows that most retail markets in the economically less developed countries function in similar ways. Such a similarity in social structures may be explained using the concept of embeddedness. This article identifies the history of socio-economic roles of rural unorganised retailers in the embedded markets of developing economies through the discourse analysis of Bengali fictional literature. 相似文献

This paper discusses an e-learning support team model developed as part of a new e-learning strategy within a tertiary education polytechnic. Based upon a community of practice model, the e-Team supports the establishment of e-learning and m-learning (mobile learning) throughout the institution as a catalyst for the adoption of social constructivist pedagogy. The paper reviews and reflects upon the impact of strategies for creating and supporting communities of practice across the institution along with the ways this model is achieving the breaking down of the barriers to ‘e’ and ‘m’ learning adoption among lecturers. This model helped to move lecturers from non-engagement to legitimate peripheral participation and onto full participation within the institution’s e-learning community, and ultimately enabling social constructivist learning environments for students. This model based on a community of practice framework for e-learning support is potentially transferable to other educational contexts. 相似文献
