The potential of a theory of variation-framed learning study, a teacher professional development approach, to help teachers overcome curricular and pedagogical challenges associated with teaching new science curricula content was explored. With a group of Singapore teachers collaboratively planning and teaching new genetics content, phenomenographic analysis of data corpus from classroom observations, teacher meetings and interviews revealed teacher learning that manifested in the teachers’ experiences. These were captured as (1) increased degrees of student-centered pedagogy and challenges to teachers’ prior assumptions about science pedagogy, (2) increased awareness of possibilities and limitations of their beliefs about science pedagogy, and (3) emergence of new understandings about new curricular content and science pedagogy. The possibility of transformative and generative learning is also discussed.  相似文献

Teachers in American study-abroad programs usually receive little, if any, training before the trip, because ‘teaching is teaching’. The cultural differences between Chinese and American university classrooms, however, affect the students' ability to learn and the teacher's ability to teach in profound ways. Foreign teachers in China require at least a basic understanding of the educational, moral and political dimensions of their classrooms if they wish to maximize the learning potential of their Chinese students. Faculty teaching abroad should be prepared for the politics of their new university department, including management styles that can hamper efforts to acclimatize to the new setting.  相似文献

Teachers participating in curricular reforms, especially reforms based on constructivism, are expected to bring about change in their teaching approach. This is often a difficult, complex and intensive process, and demands a radical reculturing of the classroom. This is also the case for social constructivist reforms in chemistry education, which are based on a context-based approach. Educational change is a social and interactional process, and during this change teachers will engage in negotiations with their students about the reform. These teacher–student negotiations have a profound impact on the succeeding of the reform. This study explores the teacher–student interactions during the reform that shape and alter the context-based chemistry approach. We focused on two teachers, of whom it was found in an earlier study that one of them succeeded in implementing the reform, while the other one struggled. By following them for one school year, in which in-depth qualitative data was collected through various instruments, we developed insights about the teacher–student negotiations that influenced the educational reform. Three themes emerged from the data: “agency of learning,” “vulnerability,” and “care.” The differences that were found between the teachers regarding these themes help explain why and how the reform can become a success and why the reform often fails to change classroom practice.  相似文献

This study examined factors that might affect researchers' willingness to collaborate with a specific researcher and the priorities given to those factors. In addition, it investigated how researchers determined the ownership of collaborative project data and how they determined the order of authorship on collaborative publications in condensed matter physics. In general, researchers rated their intrinsic motivations the highest, such as the quality of ideas a potential collaborator might have and their satisfaction with a past collaboration, followed by their extrinsic motivations, such as the complementary knowledge, skills, or resources the collaborator could provide. In addition, researchers who had a greater number of collaborative projects and researchers who had served as a project PI or co-PI valued the deep-level, personality-related characteristics of a collaborator higher than did those who had not. Younger researchers were more risk averse and more concerned with a collaborator's reputation and the possible cost of a collaboration decision. Additionally, younger researchers indicated more often than older researchers that they did not know whether their project teams followed any rules or norms or engaged in negotiation to determine the order of authorship on collaborative publications.  相似文献

Reference instruction should also involve preparing library and information science students for working with international students. There are numerous options for embedding such content into courses. In addition, professional organizations offers students with many opportunities to launch their international experiences.  相似文献

This study examined 33 mothers' and preschoolers' oral language skills (decontextualized discourse) across an emergent reading, shared reading, and oral storytelling interaction. The sample comprised primarily African American families from various socioeconomic backgrounds, ranging from Head Start families to middle-income families. Two measures of decontextualized language were assessed—literate language features and type of talk (i.e., a coding scheme categorizing comments/questions on a continuum from contextualized to decontextualized talk). Mothers used more decontextualized language during the oral storytelling interaction versus the other interactions, but children used more during the emergent reading interaction. Mothers with advanced literacy skills were more likely to make decontextualized comments/questions and use mental/linguistic verbs during the interactions. Results are discussed in terms of implications for parent-child home literacy interventions.  相似文献
