We examined third graders' understandings of condensation using an expanded notion of the Emergent Perspective, a reflexive consideration of individual and group meaning‐making situated in the culture of the classroom. Data were collected from two small groups of students in an inquiry‐based, urban classroom during a unit on the water cycle. Measures included conceptual pre‐/posttests, interviews, written work, and discourse analyses of a science lesson. Although we identified the supportive role of the teacher's explicit assessments of children's ideas, within the small groups, the force that most potently shaped meaning‐making was students' persuasive power, which was in part influenced by the rhetorical moves employed. Specifically, students' evaluative comments (a type of rhetorical move) about contributions of other group members seemed to be particularly persuasive in these groups. Evaluative comments, apart from students' academic status, were shown to be an important influence in not only social knowledge production but also in individual internalization. Our explanation focuses on the particular discursive practices as intellectual resources of urban students, but we are also mindful of the cognitive complexity of the material and the developmental abilities of the students. © 2005 Wiley Periodicals, Inc.

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.

ABSTRACT

In this case study, we first describe how teaching and research are linked in a master’s course on tissue engineering. A central component of the course is an authentic research project that the students carry out in smaller groups and in collaboration with faculty. We then explore how the students experience learning in this kind of discovery-oriented environment. Data were collected through a survey, reflective writing, and interviews. Using a general inductive approach for qualitative analysis, we identified three themes related to the students’ learning experiences: learning to navigate the field, learning to do real research, and learning to work with others. Overall, the students strongly valued learning in a discovery-oriented environment and three aspects of the course contributed to much of its success: taking a holistic approach to linking teaching and research, engaging students in the whole inquiry process, and situating authentic problems in an authentic physical and social context.  相似文献

This article explores the distinctive mentoring experiences of social work doctoral students at historically black colleges and universities (HBCUs). With a philosophical emphasis on social justice, self-determination, racial identity and pride, and social integration, social work faculty at HBCUs mentor African American and other students in PhD programs for academic achievement and successful leadership in the professoriate. The mentoring experiences at HBCUs are underpinned by tenets from relational/cultural theory and the Black feminist theory of “other mothering.” Using Howard University as a case study, this article examines relational mentoring experiences of PhD students in preparation for the academy and for leadership in social work education and practice.  相似文献

In this paper, we report an enquiry into elementary preservice teachers’ learning, as they engage in doing mathematics for themselves. As a group of researchers working in elementary Initial Teacher Education in English universities, we co-planned and taught sessions on growing pattern generalisation. Following the sessions, interviews of fifteen preservice teachers at two universities focused on their expressed awareness of their approach to the mathematical activity. Preservice teachers’ prospective planning and post-teaching evaluations of similar activities in their classrooms were also examined. We draw on aspects of enactivism and the notion of reflective “spection” in the context of teacher learning, tracing threads between preservice teachers’ retro-spection of learning and pro-spection of teaching. Our analysis indicates that increasing sensitivity to their own embodied processes of generalisation offers opportunities for novice teachers to respond deliberately, rather than to react impulsively, to different pedagogical possibilities. The paper contributes a new dimension to the discussion about the focus of novice elementary school teachers’ retrospective reflection by examining how deliberate retrospective analysis of doing mathematics, and not only of teaching actions, can develop awarenesses that underlie the growth of expertise in mathematics teaching. We argue that engaging preservice teachers in mathematics to support deliberate retrospective analysis of their mathematics learning and prospective consideration of the implications for teaching can enable more critical pedagogical choices.

Schools are traditionally seen as responsible for the educational outcomes of our children. However, schools also play an important role in the development of aspects such as self‐efficacy, participation, competence and self‐determination. As schools are often run as societies rather than communities, they offer little opportunity for these attributes (self‐efficacy, participation, competence and self‐determination) to develop. Forty‐six children aged from nine to 12 years were interviewed to ascertain their conceptualizations of the school community. The children define their school in terms of people, places for activities and interaction, a place for safety, cooperation, influence and functionality. The responses closely align to the adult conceptualizations of sense of community as purported by McMillan and Chavis (1986 McMillan, D.W. and Chavis, D.M. 1986. Sense of community: a definition and theory. Journal of Community Psychology, 14: 623. [Crossref], [Web of Science ®] [Google Scholar]). Implications of this research suggest that children can and should have an integral role in designing a curriculum and systems relevant to the school context if we are at all concerned with their psychological wellness.  相似文献

This article explores the history of Head Start, the federal early education program for economically disadvantaged preschool children in the United States, as a way of understanding what it means to talk about change in the late twentieth century. The history of Head Start has been a story of administrative changes and improvement and accountability initiatives in the realm of public policy, a ominant narrative of progress and rational planning that is consonant with a large, centralized governance structure. In an effort to create another way of conceiving of the organization, we first examine shifting definitions and conflicting interpretations of parental involvement and staff development within the program to reveal some of the tensions inherent in all human endeavors. We then draw on interviews with women who work in and are served by Head Start to show how needs and resources vary and how policy mandates can have differential—and unintended—effects. In the conclusion, we suggest, following Toulmin (1990), that the certainty and stability that has characterized public policy since the Enlightment must now be tempered with a postmodern recognition of change, complexity, and variability. Rather than one history, we see many histories. Instead of one approach, we see value in tailoring improvement initiatives to the needs of families and staff in specific circumstances.  相似文献

The creation of action research cycles is a fundamental part of action research projects. The aim of this article is to present the methodological challenge that is inherent in designing action research cycles. The article reports on my lived experience as I conceptualised and implemented a structured and systematic way of ordering and reporting the cycles within cycles in a mentoring self-study action research project. The paper discusses the journey that led to structure, and recognises the messiness that preluded this achievement within the action research process. I suggest that messiness is an inherent part of creating action research cycles. The path towards ordered structure is assisted through critical reflective practice and structured mentoring conversations. Of value to both emerging and more experienced action researchers, this article contributes to the practice of doing action research.  相似文献

This article focuses on timed tests and specifically on whether increased time enhances test performance. Three courses during the Winter 2015 term (quizzes n = 573) and three courses over the Spring 2015 term (quizzes n = 600) comprised this sample. Students were given the same tests, but the experimental group (Spring 2015) was given 50% more time than the control group. The results indicate that more time on tests did not enhance student performance in terms of higher scores.

Much attention has been given to student assessment of learning in the online classroom. One such method of measurement is online tests, quizzes, and exams. The focus of this research is to determine whether test scores would improve if students were allowed more time on tests.  相似文献

There is a large science attainment gap between students with and without special educational needs, and many students with developmental disabilities (DD) struggle to access the mainstream science programmes of study. The purpose of the present project was to pilot the use of the Early Science (ES) curriculum over a six week period with nine students with moderate to severe DD in a special education setting in the UK. Staff members indicated positive experiences of using the curriculum, especially the use of the structured teaching methodology as a helpful tool. Evaluation data suggested that all nine pupils improved their science knowledge over the course of the intervention. Some suggestions are made to improve the delivery of the ES curriculum in UK special education settings, and the need for larger scale evaluation research.  相似文献
