Pedagogical content knowledge of French as a foreign language: differences between pre-service and in-service teachers

Pedagogical content knowledge (PCK) is an important predictor of educational quality. PCK develops from various sources, such as teaching experience. Studies investigating the effects of teaching experience on PCK development mainly focus on the question whether experienced teachers differ from novices in the amount of PCK. In a mixed methods study, we study both quantitative and qualitative differences between pre-service and in-service teachers’ PCK. Total scores on a paper-and-pencil instrument are used as a measure of French PCK. To analyse the participants’ PCK in a qualitative way, answers are coded in four categories and the prevalence of answers in each category is compared between groups. Furthermore, the nature of answers is studied. No differences on our quantitative PCK measure are observed. The qualitative analysis shows that in-service teachers have more difficulties with conceptual knowledge, while showing more practical knowledge of students’ understanding than pre-service teachers.     

Archives in motion: Concrete steps towards the digital disclosure of audiovisual content

Various authors have stressed the need for an adequate archiving and preservation policy of audiovisual material, given its cultural, historical, juridical, social and economic value. In view of the sustainable preservation of audiovisual material, the opening up of the archive is seen as a real challenge. Various aspects, such as requirements concerning formats, metadata standards and legal implications, need to be taken into account. Furthermore, different types of users should be able to consult the archive in a user-friendly way, a factor which should not be neglected. This article studies and discusses the current situation in Flanders regarding the digitisation and disclosure of the Flemish audiovisual cultural heritage, comprising the audiovisual material in the archives of different Flemish institutions, including broadcasters, (post-) production companies, government institutions and cultural organizations. Based on 45 qualitative interviews, a SWOT analysis is created to assess the strengths, weaknesses, opportunities and threats concerning the digitisation and disclosure of the audiovisual archive. Moreover, this environmental analysis includes some recommendations concerning the future preservation of this audiovisual cultural heritage.     

Consumers’ Willingness to Share Personal Data: Implications for Newspapers’ Business Models

ABSTRACT

As people’s willingness to pay for digital news remains low, this article investigates whether people would be willing to share personal data as a new currency for accessing news. Increasingly, news organizations collect personal data and track cross-media consumption to build detailed knowledge about and (re)connect with digital news consumers. This article presents the results of an industry-driven big data project that allows news organizations to engage with their audience more deeply by suggesting personalized content recommendations, serving targeted advertising and/or improving the user experience. It presents the concept of the datawall, where the user pays with their data, and delivers new insights into the challenges facing data-driven business models.     

Learning from a Computer Tutor with Natural Language Capabilities

CIRCSIM-Tutor is a computer tutor designed to carry out a natural language dialogue with a medical student. Its domain is the baroreceptor reflex, the part of the cardiovascular system that is responsible for maintaining a constant blood pressure. CIRCSIM-Tutor’s interaction with students is modeled after the tutoring behavior of two experienced human tutors. The effectiveness of CIRCSIM-Tutor has been tested by 50 first-year medical students. Using a pre-test/post-test paradigm we have demonstrated that significant learning occurs during a 1 hr interaction with the program. Students were also surveyed and indicated considerable satisfaction with the program.     

The diffusion of ADSL and costs of switching Internet providers in the broadband industry: Evidence from the French case

The innovative broadband Internet industry is characterised by inertia phenomena in terms of technology choice, as well as selection of Internet service providers (ISPs). Within the set of firms providing the Internet, very often in Europe the incumbent operator has the lion's share of end-customers and supplies the dominant technology. Focusing on the French case, this paper shows that although inertia on the supply side (partly due to the regulation process itself), helps to explain the technology mix reached to date, a more complete picture of the inertia can be obtained when we consider the existence of costs faced by customers when switching between ISPs. We calculate these so-called “switching costs”. The closing section of this paper derives several implications in terms of policy.
