This paper describes a research project whose major aim was to evaluate first-year teacher education students' understanding of subject matter knowledge in the domain of area measurement. In contrast to many previous approaches to evaluating teacher education students' subject matter knowledge, the approach adopted in this study not only focused on the student teachers' substantive knowledge but also on their knowledge about the nature and discourse of mathematics, their knowledge about mathematics in society and their dispositions towards mathematics. To this end, each student was clinically interviewed whilst engaged on a set of eight tasks that were developed for the study. The development of the tasks was a major component of the study and this is described in detail. The results of the tasks are given and the paper concludes with a discussion of the findings. This discussion focuses primarily on the implications that these results have for preservice mathematics education courses. 相似文献

The blurring of distinctions between online and distance education in many parts of the developed world has led to reflections on the strategies and processes by which we create effective online learning environments for the distance education learner. In this article we argue that the foundational models of instructional design that typically inform the design, development, and delivery of online environments do not always support the epistemology and pedagogy that embodies the online environment. Through an analysis of current approaches to instructional design we present a case for adopting principles of emergence theory as a means to best harness the power and potential of design and development for online distance education. Using a prototype three‐phase design model that embodies emergent principles we advocate that to achieve the full potential of interaction and community networks through online communications requires a repositioning of roles and processes associated with “instructional design.” 相似文献

The close connection between the quality of provision for young children and professionaliation of the field has long been supported by international research. That the two are inseparable aspects of one picture is beginning to become accepted at European policy level, as evident in recent high level EU policy documents. This article explores the reciprocal relationship between quality and professionalisation, drawing on the findings of the study on ‘competence requirements in early childhood education and care’ (CoRe), jointly conducted by the University of East London and the University of Gent, and funded by the European Commission. Based on a review of literature in several European languages and data from a 15-country survey and seven in-depth case studies, CoRe has identified systemic conditions for a professionalisation of the entire early childhood system, beyond the formal qualification levels of individual practitioners. The article argues for a critical and systemic reconceptualisation of professional practice in a competent system. 相似文献

This study explored whether early elementary school aged children’s externalizing problems impede academic functioning and foster negative social experiences such as peer victimization, thereby making these children vulnerable for developing internalizing problems and possibly increasing their externalizing problems. It also explored whether early internalizing problems contributed to an increase in externalizing problems. The study examined 1,558 Canadian children from ages 6 to 8 years. Externalizing and internalizing problems, peer victimization, and school achievement were assessed annually. Externalizing problems lead to academic underachievement and experiences of peer victimization. Academic underachievement and peer victimization, in turn, predicted increases in internalizing problems and in externalizing problems. These pathways applied equally to boys and girls. No links from internalizing to externalizing problems were found. 相似文献

This paper reports on a study that focused on growth of understanding about teaching geometry by a group of prospective teachers engaged in lesson plan study within a computer-supported collaborative learning (CSCL) environment. Participation in the activity was found to facilitate considerable growth in the participants?? pedagogical-content knowledge (PCK). Factors that influenced growth in PCK included the nature of the lesson planning task, the cognitive scaffolds inserted into the CSCL virtual space, the meta-language scaffolds provided to the participants, and the provision of both private and public discourse spaces. The paper concludes with recommendations for enhancing effective knowledge-building discourse about mathematics PCK within prospective teacher education CSCL environments. 相似文献

Abstract The music business is facing hard times with declining CD sales and increasing piracy. Whereas the economic downturn is one reason for lower sales, the industry has decided to target the second factor, the fast diffusion of technologies such as CD burners and peer‐to‐peer networks like KaZaA allowing massive illegal distribution of music. Some labels focused on an offensive strategy to promote their artists. New services are being added to so called Enhanced CDs that create a new user experience. These CDs offer bonus content (i.e. videos, additional songs, pictures, or lyrics) stored directly on the CD that can be accessed on the PC. Other CDs offer (additionally) online access to actual bonus content or services (i.e. tour dates or news) if the CD is entered in the FC. The impact of these services on consumer experience has not yet been researched in depth and it remains unclear if consumers actually use the offered services on Enhanced CDs. The music label Arista has introduced several new albums on Enhanced CDs to the market providing more value to the user instead of reducing the utility by focusing only on copy protection. This article analyzes the usage of such services provided by Arista and focuses on Santana's new album “Shaman”;. Using a unique data set provided byfavakitty Media (Bandlirik) and Arista, we show for the first time what services are actually used by Santana fans and compare the results to albums of other artists such as TIC or Toni Braxton. Our results indicate that Enhanced CDs are used frequently by a relatively small group of fans, providing more value to the customer and creating a stronger relation between fans and artists. 相似文献
