This paper explores the nature of prospective teachers’ noticing of students’ understanding as they analyze and discuss middle school students’ understandings of trapezoids in micro-case videos in the context of geometry. In this exploratory study, the data were obtained from eight prospective middle school mathematics teachers through individual video analysis, reflection papers, and group discussions. The results indicated that the use of purposeful micro-case video designs based on prospective teachers’ background knowledge of quadrilaterals allowed them to be productive in video analyses and discussions. In individual video analyses, prospective teachers attended to various mathematical elements to identify students’ responses but did not always use them to make interpretations of each student’s understanding of trapezoid. In the group discussions of the micro-case videos, in contrast, prospective teachers could provide alternative interpretations of students’ understanding by identifying links between the mathematical elements in students’ responses and the characteristics of students’ understandings. In the group discussions, they provided more detailed and specific instructional actions to support each student’s understanding of trapezoid than their individual video analyses. This study suggests practical implications for teacher education programs on how to use video cases (e.g., firstly, working individually and then having group discussions about the videos) to explore prospective teachers’ professional noticing skills. Considering prospective teachers’ background knowledge of related mathematical contents, this study can also inspire future studies on how to design effective videos about students’ mathematical understanding.
Abstract In the past 50 years, museums have adapted various media for use in museum exhibitions. In the past 15 years, both the formats and the applications have changed dramatically, altering the relationships between museums and visitors, and between visitors and collections. Taking on the challenge of the newest media allows museums to experiment and to reinvigorate their interpretive programs. 相似文献

The aim of this study was to develop a measurement instrument which is compatible with literature, of which validity and reliability are proved with the aim of determining interaction perceived by learners in online learning environments. Accordingly, literature review was made, and outline form of the scale was formed with item pool by taking 14 expert opinions. As a result of exploratory factor analysis of data obtained from participation of 177 learners from eight different universities, it was seen that the scale consisted of 30 items and 3 dimensions. These dimensions are learner–content interaction, learner–instructor interaction and learner–learner interaction. Cronbach Alpha reliability coefficient of the whole scale was .95. Confirmatory factor analysis showed that fit indexes of the structure provided a good and acceptable fit. Based on these findings, Perceptions of Online Interaction Scale is a valid and reliable tool that may be used in measuring interaction occurring in online learning environments. 相似文献
Abstract Football, as other cultural products, has become a major part of the political field, since there has been an ongoing cultural battle between the President Recep Tayyip Erdo?an and his dissidents. The country is divided into two, not only between social and cultural capital owners; two sets of ideological elements, namely ‘doxas’ in reference to Bourdieusian sociology, also define the political faultlines in Turkey. Football, imported in the final years of the Ottoman Empire by the modern elite, has been intertwined with Turkish modernism and its core elements, such as nationalism. The Erdo?an regime, while dismantling the old rule, has also tried to create cultural hegemony, which has been met with dissidence. This paper analyses the role of an old military song called the ‘Izmir March’, sung in the football stands against the Erdo?an regime, discussing the elements of the two doxas in Turkey, old and new. 相似文献

This paper proposes a strategic model for assessing the coherence between companies’ knowledge strategies and their business strategies as well as in their competitive and organisational contexts. In analysing knowledge management literature, we locate three principal strategies: (1) knowledge development (internal or external), (2) knowledge sharing (codification or personalisation) and (3) knowledge exploitation (internal or external). We then position the three strategies and six related policies in the context-content-process dimensions of Pettigrew's model to create a useful framework for strategic analysis and a model to assess the coherence of companies’ knowledge strategy. The model can be used to evaluate how an existing knowledge strategy aligns with a company's characteristics and to formulate and implement a coherent knowledge strategy based on the current competitive environment, organisational context and business strategy. 相似文献
Design education is in need of a wider restructuring to accommodate new developments and paradigmatic shifts brought forth by the information age, all of which capitalise a move towards complexity theory, systems science and digital technologies. The intention of this article is to approach one particular aspect of this need: that is, how basic design education can be reconsidered to establish the arguably broken link between the ‘learning by doing’ tradition of a Bauhaus‐oriented basic design education with the computational and parametric logic necessitated by contemporary design technologies. The authors present the overall outlines of a basic design course as offered in Beykent University Department of Industrial Design in Istanbul, Turkey. The programme consists of a series of exercises grouped in five modules and two ‘binders’ that are structured to link the fundamental notions and operations of design thinking covered in basic design courses of the first year with the analytical and computational‐reasoning competencies that are developed mostly in the later years of design education. 相似文献
