An empirical study on 12th-grade students?? engagement on a global warming debate as a citizens?? conference is reported. Within the design-based research methodology, an interdisciplinary teaching sequence integrating an initiation to non-violent communication was developed. Students?? debates were analyzed according to three dimensions: communication, argumentation, and knowledge. Students regulated their oral contributions to the debate by identifying judgments in their discussions. Rhetorical processes developed by students were mainly related to the identity of debate protagonists with interest attributions, authority, and positions. Students?? arguments also relied on empirical data. The students?? knowledge focused on energy choices, economic, political, and science development issues. Implications for socioscientific issues integration in class are discussed. 相似文献

Reporting on 12 case studies of student teachers, this paper examines how experiences during teacher education affect graduates’ decision on job entrance. Interpretative data-analysis reveals that powerful sources of the shift in motivation to enter teaching concern interactions in which the person of the teacher is at stake. These mainly involve student teachers’ need to develop a socially recognized sense of professional competence as well as their dealing with social and cultural working conditions in schools. These crucial determinants act as “double-edged swords”, being at the same time important sources for recognition as for self-doubts and loss of job motivation. 相似文献

This paper evaluates the viability of using controversies in teaching. An educational project has been elaborated in which some historical-philosophical clashes were introduced into the classical syllabus of physics. The historical-philosophical controversy dealt with here, took place between the French physicists Biot and Ampère in the 19th century and referred to distinct interpretations of the Oersted experiment. This controversy was inserted into the syllabus of the 12th grade of a Brazilian secondary school. 相似文献

With growing interest in the role of teachers as the key mediators between educational policies and outcomes, the importance of developing good measures of classroom processes has become increasingly apparent. Yet, collecting reliable and valid information about a construct as complex as instruction poses important conceptual and technical challenges. This article summarizes the results of two studies that investigated the properties of measures of instruction based on a teacher‐generated instrument (the Scoop Notebook) that combines features of portfolios and self‐report. Classroom artifacts and teacher reflections were collected from samples of middle school science classrooms and rated along 10 dimensions of science instruction derived from the National Science Education Standards; ratings based on direct classroom observations were used as comparison. The results suggest that instruments that combine artifacts and self‐reports hold promise for measuring science instruction with reliability similar to, and sizeable correlations with, measures based on classroom observation. We discuss the implications and lessons learned from this work for the conceptualization, design, and use of artifact‐based instruments for measuring instructional practice in different contexts and for different purposes. Artifact‐based instruments may illuminate features of instruction not apparent even through direct classroom observation; moreover, the process of structured collection and reflection on artifacts may have value for professional development. However, their potential value and applicability on a larger scale depends on careful consideration of the match between the instrument and the model of instruction, the intended uses of the measures, and the aspects of classroom practice most amenable to reliable scoring through artifacts. We outline a research agenda for addressing unresolved questions and advancing theoretical and practical knowledge around the measurement of instructional practice. © 2011 Wiley Periodicals, Inc.

The use of information and communication technologies in higher education is surrounded by contradictory, yet interrelated
themes, that suggest that education is either experiencing a revolution or approaching its own demise. Undoubtedly, technologies
are becoming embedded in academic life but patterns of adoption are more complex and nuanced than polarized themes suggest.
The extreme polarity of a ‘promises and fears’ spectrum is unable to fully account for why this is the case; neither can it
be explained by economics, demographics, or the technology. This article argues that one of the most significant variables
in the deployment of and adaptation to information technologies in the university is academic culture. In other words, unless
we consider academic culture we cannot fully capture the relationship of technologies to education. 相似文献

This article analyses the general characteristics of the construction of the field of history of education in Brazil. To do so, it highlights the existing historiography and aims to describe the process of institutionalisation of this knowledge field, which, in general terms, has been focused on the area of teacher training. Since the nineteenth century, however, it has also been possible to identify systematic historiographical efforts in Brazil that are not directly related to the school system, but rather to the teaching of and research into the history of education within Brazilian universities. The article addresses the organisation of the field, the ways in which it has been structured and the strategies of academic legitimisation employed to achieve this. These include the regular production of dissertations and doctoral theses, the publication of books and journals, academic events and the creation of research groups and scientific associations, through which research findings have found national and international circulation. This set of indicators creates conditions for an understanding of the expansion and reconfiguration of the field of history of education that began in the 1980s, as well as of the challenges this phenomenon presents to current historiography and teacher training in Brazil. 相似文献

In the framework of teacher’s approaches to teaching, this study investigates the relationship between student-related variables (i.e., study time, class absence, domain knowledge, and homework completion), students’ approaches to learning, and teachers’ approaches to teaching using structural equation modeling (SEM) with two independent data samples. The participants were 61 biology teachers and their corresponding 1,518 high school students (12th grade). The first sample was used to fit the model, and the second sample was used to analyze the consistency of the data derived from the first sample. Using a two-level SEM analysis, we established whether the effects found at the individual level varied significantly at class level. The students’ approaches to learning were related to the teachers’ approaches to teaching as a function of the hypotheses established in the model, although the effect size was smaller than expected. However, approximately 48 % of the variance of the surface approach and 46 % of the deep approach sat at class level. At the individual level, the results of this study suggest that students’ approaches to learning significantly explain their teachers’ approaches to teaching and, thus, constitute important contextual variables. At the class level, the way students learn appears to be closely associated with class-related variables. Our data stresses the importance of promoting educational opportunities (e.g., school-based courses) for teachers to reflect upon the teaching methodologies used in class. 相似文献

STEM education has received significant attention in the USA and is largely fueled by rhetoric suggesting the USA is losing its global competitive edge and that there is a lack of qualified workers available to fill growing STEM jobs. However, a counter discourse is emerging that questions the legitimacy of these claims. In response, we employed feminist critical policy analysis as both a theory and a method to further critique the STEM crisis discourse. We argue that the nature of the current discourse is misleading at worst and incomplete at best and show who is fueling the crisis discourse and who stands to win or lose as a result. We reveal how the crisis discourse draws attention away from the multi-layered complexity of the issue and surface what is missing in the discourse to re-center public attention on protracted problems that still need dismantling. 相似文献

Abstract This conceptual paper is based on two propositions: 1.) An efficient flexibility management is a critical success factor for media companies. 2.) The concept of real options theory (ROT) aims at improving a company's flexibility management. As a consequence, it is analysed how ROT can contribute to the flexibility management in media companies. In this context, two research issues are investigated. First, it is shown that real options as substantiations of flexibility are of great importance for media companies: In doing so, it is outlined that options which focus on a company's fixed costs management and options which aim at improving a company's sales situation are of high relevance for all segments in the media industry. Contrarily, options which focus on a company's variable costs are only relevant for media companies engaged in the print segment. Second, it is illustrated how ROT can contribute to the reactive and proactive management of flexibility in media companies. 相似文献
