Science education researchers are concerned with preparing pre-service elementary teachers (PSETs) to teach in ways that support students to learn science in a meaningful way. Preparing elementary teachers to teach science is complicated given that they tend to be generalists and may not have the same experience with science as secondary teachers. During an elementary science methods course, we explored PSETs?? perspectives on the teaching and learning of science via a case study that included four PSETs. Using Frykholm??s (Journal of Curriculum and Supervision 19:125?C149, 2004) framework of ??educative?? and ??debilitating?? discomfort, we examined PSETs?? approaches to their own science learning and their approaches to science teaching. A theme apparent in PSETs?? perspectives was struggle. We described ways in which struggle was either educative or debilitating for PSETs, both in terms of their own learning and the ways in which they approached teaching. Some PSETs who struggled in their own learning developed learning experiences to engage their students in reform-based science teaching, while some PSETs developed learning experiences that prevented their students from experiencing any sort of struggle in their learning process. The ways in which these students dealt with their own learning struggles mirrored the ways in which they dealt with their struggles to become teachers of reform-based science instruction. Helping PSETs to deal with their feelings of discomfort with science content or ideas about the nature of science learning and teaching promoted by reform documents may be a key issue in developing their willingness to become facilitators of meaningful science learning.  相似文献

This paper is based upon three stories which were told by respondents in a study of how survivors, mothers of survivors and teachers of survivors cope in the aftermath of child sexual abuse. These stories relate to interactions in the school or workplace and are discussed within the broader context of existing stereotypes and assumptions about abuse. The paper argues that assumptions about abuse can affect outcomes and can cause distress to others who become involved in dealing with it.  相似文献

In this study, we explore the extent to which two instructional techniques promote critical discourse in an online class on educational standards and curriculum: instructor stance (challenging/nonchallenging) and topic level (higher order/lower order). Posts from 25 students, across four modules, were analyzed. These four modules constituted approximately one third of the course, and were selected because the professor was the sole facilitator for them. Results indicate that, regardless of topic level, a challenging stance by the professor had a positive effect on the percentage of student posts that referenced readings and theory. There was an interaction between level and stance on student use of reasoned argument. Lower order challenging forums were associated with a greater percentage of reasoned posts. This may be due to the abstractness of the professor's probes in higher order forums. Implications for future research include empirical investigations incorporating contextual variables and qualitative studies to ascertain how students engage with bulletin boards.  相似文献

We examined whether university students who report a significant history of reading difficulties (RD; n = 24) differed from university students with no history of reading difficulties (NRD; n = 31) in how sentence context affects word recognition. Experiment 1 found no differences in how congruent sentence primes or syntactic manipulations of the sentence primes affected the performance of the two groups. However, only the RD group displayed a significant inhibition effect when the target word was preceded by an incongruent sentence prime. Experiment 2 found that the groups differed in how meaning frequency of the target word and context strength of the sentence prime affected word recognition latencies. The results suggest that the RD participants’ performance is context-sensitive and better explained by interactive models of language processing than by modular models.  相似文献

Digitised versions of archival fonds with micro or regional significance daily join mass digitisation projects of books and documents in the global digital space. For historians, the exponential expansion of searchable digital archival material has required the revision of traditional research methods. The digital age has also shifted disciplinary boundaries such as the distinction between historian and archivist. This article concerns a micro digitisation involving collaboration between historian and archivist, not in archive access as is usually the case, but in archive creation. The experience of this collaboration is generalisable to other micro-scale uploads of scanned material enabled by digital technologies. This article is a case study of this experience. It uses autoethnography to explore the practicalities and ethical processes of decision-making to create a new digital archive of wine history during the pilot stage of an Australian Research Council Industry Linkage Grant. The decision-making process that transformed a historian as traditional archive end-user to archive creator highlights the challenges for both professions in the decision to digitise, the implications for expenditure of public funds and questions of digitisation and environmental sustainability.  相似文献

This study compared the quality of child care programs serving children receiving government subsidies to those not serving such children. Thirty-four classrooms in full day programs serving preschool aged children (19 subsidized, 15 unsubsidized) were observed using the Early Childhood Environment Rating Scales-Revised (ECERS-R). (1) Research Findings: One way ANOVA indicated that programs not serving children receiving subsidies were rated higher on overall quality, language and reasoning, learning activities, and social interactions. Teacher salary was significantly correlated with overall quality, and after controlling for teacher salary, subsidy density did not uniquely predict variance in overall quality. (2) Policy Implications: Overall low quality indicates a need for a quality improvement initiative using proven methods. Minimum guidelines for quality beyond state licensing standards should be used to ensure that children in subsidized programs are receiving adequate care and to oversee state and federal investments in early childhood education.  相似文献

Many new science teachers are assigned to teach subjects in which they have not been prepared, a practice referred to as out‐of‐field (OOF) teaching. Teaching OOF has been shown to negatively influence instruction and constrain teachers’ development. In this study, we explored the extent to which new secondary science teachers were assigned OOF across their first 5 years. Analysis of this longitudinal data set indicated that these assignments were common. While new science teachers were assigned to teach a variety of subjects over their first 5 years of teaching, they were not assigned more or fewer OOF courses over time. Furthermore, results indicated that teachers in certain situations are more likely than others to be assigned to teach OOF. Even with federal legislation in the United States seeking to eliminate OOF teaching, a large portion of new secondary science teachers are assigned to teach science disciplines for which they are inadequately prepared. Based on the findings of this study, it is worth exploring policy avenues that eliminate OOF teaching. Policymakers, administrators, and teacher educators should seek to provide supports, such as science‐specific induction programs designed for new teachers who are assigned OOF, and science teacher educators should prepare prospective teachers to teach multiple science disciplines. © 2017 Wiley Periodicals, Inc.
