Students’ meaning making in science: solving energy resource problems in virtual worlds combined with spreadsheets to develop graphs     

Ingeborg Krange  Hans Christian Arnseth 《Cultural Studies of Science Education》2012,7(3):585-605

The aim of this study is to scrutinize the characteristics of conceptual meaning making when students engage with virtual worlds in combination with a spreadsheet with the aim to develop graphs. We study how these tools and the representations they contain or enable students to construct serve to influence their understanding of energy resource consumption. The data were gathered in 1st grade upper-secondary science classes and they constitute the basis for the interaction analysis of students?? meaning making with representations. Our analyses demonstrate the difficulties involved in developing students?? orientation toward more conceptual orientations to representations of the knowledge domain. Virtual worlds do not in themselves represent a solution to this problem.  相似文献   

e‐Learning in universities: Supporting help‐seeking processes by instructional prompts     

Silke Schworm  Hans Gruber 《British journal of educational technology : journal of the Council for Educational Technology》2012,43(2):272-281

University students are more responsible than school students for their own learning. The role of self‐regulated learning increases in virtual e‐learning course environments. Academic help‐seeking is an important strategy of self‐regulated learning, but many students fail to use this strategy appropriately. A lack of information and a perceived threat of help‐seeking may cause this effect. Among others, giving prompts is an instructional means to support students to adequately apply academic help‐seeking . A study is presented in which the effect of giving prompts on the quantity and quality of academic help‐seeking was experimentally investigated in a blended university learning course of educational science. Compared with students who received no prompts, students with prompts about the relevance of active help‐seeking had better learning outcomes, participated more actively in online learning activities, more explicitly referred to learning contents in the forums and took more initiative in starting discussions. The perceived threat of help‐seeking could not be reduced, however.  相似文献   

Teacher Recruitment in Context: Differences between Danish and Finnish Beginning Teacher Education Students     

David Reimer  Hans Dorf 《Scandinavian Journal of Educational Research》2014,58(6):659-677

Against the background of differing admission selectivity, structure, and status of teacher education in Denmark and Finland, we analyze the extent to which beginning teacher education students differ with respect to previous educational pathways, socio-demographic characteristics, academic self-concepts, and occupational motivations. In both Denmark and Finland, representative groups of first-year teacher education students and final-year upper-secondary students were surveyed. The collected data enabled us to characterize teacher education students in contrast to a baseline reference group of school students and to compare these differences across countries (difference-in-differences estimation). The results of our study indicate that Danish student teachers lag behind their Finnish peers in the valuation of their math skills. In addition, the average motivational profiles of Danish and Finnish teacher education students differ markedly. Implications of our findings are discussed.  相似文献   

Differential growth patterns in emerging reading skills of Turkish-German bilingual and German monolingual primary school students     

Christina K. Limbird  Jessica T. Maluch  Camilla Rjosk  Petra Stanat  Hans Merkens 《Reading and writing》2014,27(5):945-968

Students from Turkish-speaking families are the largest minority language group in Germany. Yet, little is known about this group’s literacy development. Using data from a 3-year longitudinal study, we examined whether the same base reading skills are involved in early reading comprehension of 100 Turkish-German bilingual and 69 German monolingual children. We applied a basic theoretical model of reading development to examine how emerging literacy develops for monolingual compared to bilingual children. Both the bilingual and monolingual children in this sample developed the investigated base reading skills at the same rate. However, the relations among phonological awareness, German vocabulary, and word decoding showed differential patterns in the development of German reading comprehension skills for the two groups: monolingual children appeared to make use of their phonological awareness skills more, whereas reading comprehension depended more on vocabulary skills for bilingual readers. Our findings indicate that bilingual emerging readers require specialized models of reading development to account for their unique routes into reading comprehension. The results of the study point to a need for increased attention to vocabulary building in the early phases of literacy acquisition for bilingual children.  相似文献

Today's news — tomorrow's context: A dynamic model of news processing     

Hans Mathias Kepplinger  Gregor Daschmann 《广播与电子媒介杂志》2013,57(4):548-565

We are proposing a feedback model of news processing, assuming that news reception is guided by media input as well as by existing cognitive structures. However, these structures are in turn shaped by former media coverage. In our study we examine viewers’ processing of TV news, comparing objective news content (content analysis) to subjective meaning of news stories (viewer interviews). Results show that viewers interpret information about new events in the context of past events, themselves mainly a reflection of former media coverage.  相似文献   

‘Héloïse’: towards a co‐ordinated ecosystem approach for the archiving of scientific publications?     

Hans DILLAERTS  Ghislaine CHARTRON 《Learned Publishing》2013,26(3):173-179

With the continued development of open access policies, it is important to promote consensus‐building projects with the various stakeholders. This article gives an account of how such collaboration has facilitated the construction of the project Héloïse. This project is a French information service dedicated to describing the policies of French publishers on the self‐archiving of scientific publications. Héloïse represents a real tool of mediation whose development involved much debate between publishers and research stakeholders. This article seeks to demonstrate that the development of trust between the actors involved in the project was a major component of its success.  相似文献
