Developing conceptual understanding in ray optics via learning with multiple representations     

Rosa Hettmannsperger  Andreas Mueller  Jochen Scheid  Wolfgang Schnotz 《Zeitschrift für Erziehungswissenschaft》2016,19(1):235-255

A particular difficulty in physics learning is the fact that pupils’ “intuitive” concepts are often resistant to instruction. This article reports empirical results from two related studies within an interdisciplinary project of physics education and educational psychology in ray optics. Two different kinds of treatment groups (TG A and TG B), both targeted at widespread pupils’ intuitive concepts (N?=?511), were compared with the results of a control group (CG C) learning with conventional tasks (N?=?218) provided by a related study II. Pupils in TG A) of study I worked on cognitively activating tasks related to widespread intuitive concepts in ray optics explicitly requiring them to deal with multiple representations. Pupils in the TG B) of study I worked on the same intuitive concepts, but without the cognitively activating representational component. TG A) and B) were compared with each other and with CG C) learning with conventional tasks. The results indicated that tasks addressing widespread intuitive pupils’ concepts improved conceptual understanding significantly more than conventional tasks. There was evidence of a significant intermediate effect showing medium-term stability.  相似文献

Marketisation of adult education: principals as business leaders,standardised teachers and responsibilised students     

Andreas Fejes  Caroline Runesdotter  Gun-Britt Wärvik 《International Journal of Lifelong Education》2016,35(6):664-681

The marketisation of education is a global phenomenon and has attracted increased interest during the last three decades, not least in terms of research on school choice and its consequences. However, while much research has been conducted on the marketisation of schooling, less attention has been directed at adult education. In this paper, focus is directed at institutional logics and institutional responses to the process of marketisation of adult education. More specifically, we focus on how a procurement system, implemented in order to create competition and to increase quality in adult education, influences how students construe themselves, as well as the way principals and teachers work. Our results indicate that teachers emerge as the main source of resistance towards an institutional logic emerging in the wake of marketisation, while principals and students to a large extent conform to the emerging institutional demands.  相似文献

Unpacking challenges of data commentary writing in master’s thesis projects: an insider perspective from chemical engineering     

Andreas Eriksson  Lene Nordrum 《Research in Science & Technological Education》2018,36(4):499-520

Background Data commentary, in-text comments on the visual presentation of data, is acknowledged as a central aspect of academic writing in many engineering disciplines. At the same time, it is a feature that has been shown to be challenging for students. One of the genres in which data commentary plays a significant role in many engineering disciplines is the master’s thesis. Comparatively little research has been done on the process of master thesis supervision, and combining the study of data commentary and master’s thesis supervision is therefore particularly interesting.

Purpose This study explores the challenges of data commentary writing through interviews with master’s students and thesis supervisors of chemical engineering.

Sample and method Master’s students at a Swedish university were invited to participate in a workshop about the writing of data commentary. Nine master’s students and five supervisors were interviewed about what is difficult and important about writing data commentaries in their discipline as well as about decisions made in data commentaries written by the students. The interviews were divided into a semi-structured and a discourse-based part.

Results Our results indicate that data commentary comes with a variety of challenges. Among the most difficult and important aspects are selection of content and clarity. The study also indicates a close connection between data commentary and disciplinary learning in chemical engineering, suggesting that highlighting data commentary in the teaching of master’s thesis writing will be time well spent.

Conclusions In order to make the teaching and learning of data commentary effective in the context investigated, we propose that important measures are: the development of a shared metalanguage among students and supervisors, a genre approach, and collaboration between engineering and communication faculty.  相似文献   

Re-inventing the Historical in Comparative Education: Reflections on a protean episteme by a contemporary player     

Andreas M. Kazamias 《比较教育学》2001,37(4):439-449

It has been said, not in jest, that while the future may be predictable, the past is unpredictable. This essay first constructs yet another, but hopefully different, historical overview of the episteme of comparative education in the USA, the American comparative proteus (after the Greek mythical sea-god who, according to the Oxford English Dictionary , would assume different shapes and appearances 'to avoid answering questions'). The focus of the second section is a comparative view of the British comparative proteus. In both cases, the analysis is focused on the epistemological-cum-methodological orientations of the two 'comparative educations'. It is argued that in the period after the 1960s the two proteuses were metamorphosed from essentially being historical to social scientific. In the third section it is argued that this metamorphosis has impoverished the field, and a call is made for the re-invention of the historical dimension in comparative education. It is further argued that the reclamation of the historical legacy, among other things, would help to humanise comparative education in a cosmos of economic globalisation and instrumental rationality.  相似文献   

Wann sollten computerbasierte Verfahren zur Messung von Kompetenzen anstelle von papier- und bleistift-basierten Verfahren eingesetzt werden?     

Andreas Frey  Johannes Hartig 《Zeitschrift für Erziehungswissenschaft》2013,16(1):53-57

Currently, competencies are mostly assessed with paper and pencil tests. Nevertheless, for some competencies, using paper and pencil tests is problematic for three reasons. For (a) competencies requiring complex interactions under time constraints, (b) complex competence constructs, and (c) competencies requiring using a computer, a computer-based assessment provides several advantages compared to a paper and pencil-based assessment. Nevertheless, none of the two testing media is superior to the other in a general way. Thus, the testing medium which provides the best opportunities for a proper operationalization of the competence construct at stake should be selected. If both paper and pencil and computer seem applicable for measuring a competence construct, precisely costing out and comparing the two alternatives is recommended. Within this comparison, not only the additional costs caused by using computers but also the specific costs of paper and pencil-based assessment should be considered.  相似文献   

International networking for sexuality education: a politically sensitive subject     

Katharina Steinhart  Andreas von Kaenel  Stella Cerruti  Pedro Chequer  Rebeca Gomes  Claudia Herlt 《Sex education》2013,13(6):630-643

In 2007, six countries (Argentina, Brazil, Chile, Paraguay, Peru and Uruguay) commenced work on a project to harmonise public policy on school sexuality education (SE) and the prevention of HIV. Inter-sectoral management committees for SE involving ministries of education, ministries of health and civil society were established, national policies and work plans were formulated and implemented, and SE/HIV prevention activities were carried out. The strengths and weaknesses of implementation were assessed. After this, the beginnings of a community of practice were created, with national focal points. This paper analyses the above process using qualitative data generated through semi-structured questionnaires and interviews, with a focus on the perceived contribution of regional collaboration to the development of national policies, national curricula and implementation. Overall, the initiative reached 83,000 teachers and 1,500,000 pupils. Training materials and national curricula and policies were developed, introduced and implemented. Regional collaboration improved political institutionalisation, information exchange, inter-sectoral collaboration, civil society participation, programme legitimacy and the perception of SE as a young person's right. The initiative offers a model for other countries, with regional collaboration helping to establish the case for SE both normatively and institutionally at the political level, mitigate obstacles in the context of such a politically sensitive topic as SE and provide a forum for discussion and the exchange of information which in turn helped legitimise and operationalise national SE policies.  相似文献   

Consumer Use and Business Potential of Virtual Worlds: The Case of “Second Life”     

Andreas M. Kaplan  Michael Haenlein 《媒体管理杂志》2013,15(3-4):93-101

Abstract

Several months ago, the virtual social world “Second Life” (SL) received considerable interest in both the popular and business press. Based on a series of 29 qualitative, in-depth interviews, this article investigates what types of behaviors consumers show within this environment and what business opportunities it offers for companies. The results indicate that users do not consider SL as a mere computer game but as an extension of their real lives. This has implications for how marketing managers can use this online application that go beyond those known from traditional computer or online games.  相似文献   

Online Producers: Studying the Information Needs and Internet Seeking Behavior in the Agricultural Sector     

Petros Kostagiolas  Andreas Souliotis  George Boskou 《International Information and Library Review》2013,45(3-4):137-148

The agricultural sector is changing due to the advancing information technologies and the internet. Information is required by agricultural producers which cover all aspects of agricultural production including the processing of agricultural products on-farm or in rural areas. The abundance of agricultural information however does not necessarily imply better informed producers, especially if their information behavioral patterns are not studied. A review of the literature on producers’ information needs and an empirical study on olive and olive oil producers is presented. The theoretical construct of the survey is informed by Wilsons’ macro model of information-seeking behavior. This is employed in order to understand information needs, preferred information resources, as well as obstacles in information seeking of olive and olive oil producers. The survey provides new information behavior results for producers’ information spaces, which in turn are creating a new global business agricultural production model. Through this perspective appropriate information services can be developed in order to meet specific information needs and information behaviors in the agricultural sector.  相似文献
