Model progression denotes the organization of the inquiry learning process in successive phases of increasing complexity. This study investigated the effectiveness of model progression in general, and explored the added value of either broadening or narrowing students?? possibilities to change model progression phases. Results showed that high-school students in the ??standard?? model progression condition (n?=?19), who could enter subsequent phases at will, outperformed students from a control condition (n?=?30) without model progression. The unrestricted condition (n?=?22) had the additional option of returning to previous phases, whereas the restricted condition (n?=?20) disallowed such downward progressions as well as upward progressions in case insufficient knowledge was acquired. Both variants were found to be more effective in terms of performance than the ??standard?? form of model progression. However, as performance in all three model progression conditions was still rather weak, additional support is needed for students to reach full understanding of the learning content.  相似文献   

Engaging students in higher education through mobile learning: lessons learnt in a Chinese entrepreneurship course     

Thomas Menkhoff  Magnus Lars Bengtsson 《Educational Research for Policy and Practice》2012,11(3):225-242

This evaluative?Cexploratory case study reports pedagogical experiences with using mobiles phones, wikis, and other mobile learning approaches such as podcasts and walking tours as educational tools in the context of an undergraduate course on Chinese Entrepreneurship and Asian Business Networks taught at a university in Singapore. Conceptualized as mobile learning, the paper argues that information and communication technologies (ICT) devices used by Gen Y students as part of their everyday life such as hand phones in combination with social media platforms such as course wikis and other proven pedagogical methods such as mini lectures, field visits, and walking tours can greatly enrich learners?? experience and produce valuable learning outcomes on the basis of blended learning provided their usage is easy and effectively integrated into the respective instructional strategy.  相似文献

Classifying Amharic webnews   总被引：1，自引：1，他引：0

We present work aimed at compiling an Amharic corpus from the Web and automatically categorizing the texts. Amharic is the second most spoken Semitic language in the World (after Arabic) and used for countrywide communication in Ethiopia. It is highly inflectional and quite dialectally diversified. We discuss the issues of compiling and annotating a corpus of Amharic news articles from the Web. This corpus was then used in three sets of text classification experiments. Working with a less-researched language highlights a number of practical issues that might otherwise receive less attention or go unnoticed. The purpose of the experiments has not primarily been to develop a cutting-edge text classification system for Amharic, but rather to put the spotlight on some of these issues. The first two sets of experiments investigated the use of Self-Organizing Maps (SOMs) for document classification. Testing on small datasets, we first looked at classifying unseen data into 10 predefined categories of news items, and then at clustering it around query content, when taking 16 queries as class labels. The second set of experiments investigated the effect of operations such as stemming and part-of-speech tagging on text classification performance. We compared three representations while constructing classification models based on bagging of decision trees for the 10 predefined news categories. The best accuracy was achieved using the full text as representation. A representation using only the nouns performed almost equally well, confirming the assumption that most of the information required for distinguishing between various categories actually is contained in the nouns, while stemming did not have much effect on the performance of the classifier.

Where is the engineering I applied for? A longitudinal study of students' transition into higher education engineering,and their considerations of staying or leaving     

Henriette Tolstrup Holmegaard  Lene Møller Madsen  Lars Ulriksen 《European Journal of Engineering Education》2016,41(2):154-171

This paper presents results from a qualitative longitudinal study of students' transition into higher education engineering. The study aims at comparing upper-secondary school students' expectations of engineering with their actual experiences when encountering the engineering programme. It explores how this encounter provides a platform for students to become integrated during first year. We find that students' expectations are poorly met by their first-year study programme. In their attempt to bridge the gap between their expectations and their experiences, the students apply three strategies: some endure the gap, some constantly try out different study strategies and some compromised their expectations and identities to become more aligned with the study programme. The findings show that even when students successfully manage to bridge the gap, their strategy may turn out to be counterproductive from a learning point of view. The implications of the study are discussed.  相似文献   

Choices and changes: Eccles’ Expectancy-Value model and upper-secondary school students’ longitudinal reflections about their choice of a STEM education     

Eva Lykkegaard  Lars Ulriksen 《International Journal of Science Education》2016,38(5):701-724

During the past 30 years, Eccles’ comprehensive social-psychological Expectancy-Value Model of Motivated Behavioural Choices (EV-MBC model) has been proven suitable for studying educational choices related to Science, Technology, Engineering and/or Mathematics (STEM). The reflections of 15 students in their last year in upper-secondary school concerning their choice of tertiary education were examined using quantitative EV-MBC surveys and repeated qualitative interviews. This article presents the analyses of three cases in detail. The analytical focus was whether the factors indicated in the EV-MBC model could be used to detect significant changes in the students’ educational choice processes. An important finding was that the quantitative EV-MBC surveys and the qualitative interviews gave quite different results concerning the students’ considerations about the choice of tertiary education, and that significant changes in the students’ reflections were not captured by the factors of the EV-MBC model. This questions the validity of the EV-MBC surveys. Moreover, the quantitative factors from the EV-MBC model did not sufficiently explain students’ dynamical educational choice processes where students in parallel considered several different potential educational trajectories. We therefore call for further studies of the EV-MBC model's use in describing longitudinal choice processes and especially in investigating significant changes.  相似文献   

Designing the Auditor: A Prototype of Locative Radio with Original Sound Content     

Lars Nyre  Jon Hoem  Bjørnar Tessem  Johannes Ringheim 《Journal of Radio & Audio Media》2017,24(1):90-110

Location-based sound media are similar to traditional radio in that they rely on communication in sound alone. The smartphone has GPS and Bluetooth, and it is easy to attach sound to locations like a rail station, a neighborhood, or a street. The research team designed a media prototype, Auditor, and produced a soundscape called “The Railroad Dialogues.” The medium and content were tested in a field trial with 42 young, urban headphone listeners. The article reports on the informants’ level of immersion in the sound content and interface, and considers their potential to supplement radio in the future.  相似文献   

The Changing Ecology of Tools for Live News Reporting     

Frode Guribye  Lars Nyre 《Journalism Practice》2017,11(10):1216-1230

Broadcast news channels provide fresh, continuously updated coverage of events, in sharp competition with other news channels in the same market. The live moment is a valuable feature, and broadcasters have always relied on teams that can react quickly to breaking news and report live from the scene. Technology plays an important role in the production of live news, and a number of tools are applied by skilled actors in what can be called an ecology of tools for live news reporting. This study explores new video tools for television news, and the tinkering conducted by the reporting teams to adapt to such tools. Six journalists and photographers at broadcaster TV 2 in Norway were interviewed about their everyday work practices out in the field, and we present the findings in an analysis where six aspects of contemporary live news reporting are explored: (1) from heavy to light equipment, (2) more live news at TV 2, (3) the practice of going live, (4) the mobility of live reporters, (5) tinkering to go live, and (6) quicker pace of production. In the concluding remarks we summarize our insights about live news reporting.  相似文献
