Building and Maintaining the Common Ground in Web-Based Interaction
2002
In this paper, the main purpose is to explore how participants establish and maintain the common ground in the computer-based conferences. Previous studies assume that before the participants can reach the deeper level interaction and learning, they have to gain an adequate level of common ground (Dillenbourg, 1999; Baker et al., 1999; Veerman, 2000). Subjects were 68 pre-service teachers and 7 mentors from three universities who participated in the web-based conferencing course for eight weeks. The results assume that in deeper level discussions it is essential that participants, especially fellow students did give not only the evidence about their own understanding by using written feedba…
Information structure and practice as facilitators of deaf users' navigation in textual websites
2009
Deaf users might find it difficult to navigate through websites with textual content which, for many of them, constitutes the written representation of a non-native oral language. With the aim of testing how the information structure could compensate for this difficulty, 27 prelingual deaf users of sign language were asked to search a set of headlines in a web newspaper where information structure and practice were manipulated. While practice did not affect deep structures (web content distributed through four layers of nodes), wide structures (web content concentrated in two layers) did facilitate users' performance in the last trial block and compromised it in the first trial block. It is…
Tailoring of Feedback in Web-Based Learning: The Role of Response Certitude in the Assessment
2008
This paper analyzes the challenges of tailoring feedback to the student’s response certitude during the assessment in Web-based Learning systems (WBLSs). We present the summary of the results of a series of experiments related to the online assessment of students through multiple-choice quizzes, where students had to select the confidence level and were able to request different kinds of feedback for each of the answered questions.
News Consumption in the Mobile Era
2014
Mobile devices allow users to keep ubiquitously connected to the internet. Consequently, they change the reception of information by faster access, greater timeliness, and new media usage contexts. At the same time, many traditional media organizations already produce content for mobile websites and apps in line with cross-media strategies. Reflecting severe structural changes in the journalism market, they are hoping to manage the digital transition successfully by mobile publishing, (re)gaining especially the digital natives. Referring to the media repertoire approach, we examine the role of mobile devices on two different levels. First, from a technical point of view, we consider the pla…
The effect of time and place dependence when utilizing video lectures
2009
In many learning institutes, diversification of teaching with the help of various technologies has become an essential part of educational arrangements. With the increase in the use of networks for teaching purposes, the use of streaming videos is now one of the possibilities to be reckoned with in trying to increase flexibility in studies. Specially recorded on-demand videos provide the students with better chances to decide when, where and how to study. Information on how students use on-demand videos can be obtained, apart from student questionnaires, from the log files of a media server. These files offer an information source that, on the one hand, is diverse but, on the other, cumbers…
Scientific electronic book
2012
This paper examines the influence of the loss of reference points for the digital readout in user interaction. This has been done using 5 eBooks from different disciplines, accessed through various consultation platforms. We have examined different aspects of the information architecture of these sites to find out if users are aware of their location in the text during reading and maintaining control to scroll through it. The results indicate the need to design more robust information architectures to overcome the problems of loss of location and convert the digital reading experience into a viable alternative
Multimedia and Internet Systems : Theory and Practice
2013
Aleksander Zgrzywa, Kazimierz Choro, and Andrzej Siemiski (Eds.) Multimedia and Internet Systems: Theory and Practice During the last 20 years we have witnessed a rapid development of Multimedia and Network Information Systems. What is even more important, the pace of change does not show any sign of slowing. When we look back we see how many research projects that have originated at various universities or in research facilities are now part of our everyday life. This monograph offers the reader a very broad review of the most recent scientific investigations in that area. The book is a collection of carefully selected and the most representative investigations, solutions, and applications…
LifeRescue Software Prototype for Supporting Emergency Responders During Fire Emergency Response: A Usability and User Requirements Evaluation
2017
For an efficient emergency response, emergency responders (ERs) should exchange information with one another to obtain an adequate understanding and common operational picture of the emergency situation. Despite the current developments on information systems, many ERs are unable to get access to the relevant information as the data is heterogeneous and distributed at different places and due to security and privacy barriers. As a result, ERs are unable to coordinate well and to make good decisions. Therefore, to overcome these difficulties, a web-based application called LifeRescue was developed for supporting easy information access during emergency search and rescue operation. The goal o…
A multimedia approach to the efficient implementation and use of emergency plans
2004
Because of the complexity of emergency procedures, the stressful situations during which they're executed, the emergency plan must be meticulously designed so that safety managers can quickly find needed information. Regardless of the complex procedures it describes and the trying situations where it would be used, the plan's success is always measured by how effective the evacuation is. Thus, safety-conscious organizations continually try to improve their emergency procedures and the way they present them in the emergency plan. Integrating incoming information during an emergency and correlating this information with the plan's procedures is a manual task for many safety managers. The dang…
Video feedback in higher education - a contribution to improving the quality of written feedback
2012
Author's version of an article in the journal: Nordic Journal of Digital Literacy. Also available from the publisher at: http://www.idunn.no/ts/dk/2012/02/video_feedback_in_higher_education_-_a_contribution_to_impr The purpose of this article is to promote the significance of feedback regarding students’ working with written texts in higher education and to point out how technology can develop the quality and form of teachers’ feedback. The results of studies and tests completed in eight separate subject areas demonstrate that video feedback simplifies and increases the efficiency of responding to students’ work, as it allows the opportunity to achieve increased levels of precision and qual…
