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…

KIND-DAMA: A modular middleware for Kinect-like device data management

2017

Summary In the last decades, we have witnessed a growing interest toward touchless gestural user interfaces. Among other reasons, this is due to the large availability of different low-cost gesture acquisition hardware (the so-called “Kinect-like devices”). As a consequence, there is a growing need for solutions that allow to easily integrate such devices within actual systems. In this paper, we present KIND-DAMA, an open and modular middleware that helps in the development of interactive applications based on gestural input. We first review the existing middlewares for gestural data management. Then, we describe the proposed architecture and compare its features against the existing simila…

Peer-assessment using test exams in a Sakai-based e-learning platform

2021

We report our work on the implementation of a learning innovation based on the combination of peer-assessment and formative learning. The methodology consists on the students themselves to propose, review and select questions for the subsequent creation of a "multiple choice" exam to assess their progress. This learning innovation is carried out with a minimum intervention from the lecturer by using testing tools from the Sakai-based e-learning platform of our institution in combination with several software functions that have been created to automate the aggregation and processing of the students’ contributions. According to the feedback collected from the students, these learning tasks h…

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…

Combining traditional and indirect augmented reality for indoor crowded environments. A case study on the Casa Batlló museum

2017

Abstract Mobile audio-guides are currently being used in museums to enhance the visitors’ experience. Over the past few years, some Augmented Reality (AR) solutions have been explored in this context, making it possible to provide augmented visual and sonic stimuli through the use of smartphones. However, the special conditions of museums (e.g. artificial markers cannot be used, small, crowded rooms, etc.) and the limited computational capacity of smartphones mean that there are important restrictions in the use of this technology. In this paper we introduce a novel mobile augmented guide for the Casa Batllo museum (Barcelona, Spain) which is based on a combination of traditional and indire…

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

Gestural and audio metaphors as a means of control for mobile devices

2002

This paper discusses the use of gesture and non-speech audio as ways to improve the user interface of a mobile music player. Their key advantages mean that users could use a player without having to look at its controls when on the move. Two very different evaluations of the player took place: one based on a standard usability experiment (comparing the new player to a standard design) and the other a video analysis of the player in use. Both of these showed significant usability improvements for the gesture/audio-based interface over a standard visual/pen-based display. The similarities and differences in the results produced by the two studies are discussed

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…
