[publication] Impacts of Interactions in Learning-Videos: A Subjective and Objective Analysis #tugraz

Our publication at this year ED-Media 2015 conference „Impacts of Interactions in Learning-Videos: A Subjective and Objective Analysis“ is now online available. You can find the described information system LIVE right here.

Abstract:

It is clear that a system known as selective attention is the most crucial resource for human learning (Heinze et al. 1994). Due to this fact a web based information system is developed to support the attention of the watchers of a learning video. This is done by enriching the video with different forms of interactions. Among others there are interactions presenting multiple-choice questions at predefined positions in the video as well as randomly occurring interactions displaying general questions, which are not content related. To gain a basic plan which points out how to distribute the interactions over the video the usage of the information system at a lecture is analyzed. For that on the one hand some feedback of the users is provided and on the other hand an objective analysis of the results of the multiple-choice questions is done by evaluating their time of occurrence in the video.

[publication] Design and Evaluation of a User Interface for an Interaction Supported Video Platform

Our contribution about „Design and Evaluation of a User Interface for an Interaction Supported Video Platform“ at this year uDay in Dornbirn is now online available.

Abstract:

Learning videos are currently more and more in use because of the evolving trend of so-called MOOCs (Massive Open Online Courses) (Khalil & Ebner, 2013). However learning videos have only a con-suming character due to the fact that they are of passive nature. According to Carr-Chellman & Duchastel (2000) interaction as well as communication are key features of a successful online course. Because of that a web based information system has been developed to support learning videos with different forms of interac-tion (Ebner et al., 2013). It is obvious that such an information system has to be easily useable and due to that this research study presents the development process of a suitable User Interface (UI). The associated usabil-ity study as well as the field study point out that the design approach is generally working and also identified some components to improve

[publication] Support of Video-Based lectures with Interactions – Implementation of a first prototype

Our contribution at this year ED-MEDIA conference in Tampere, Finnland about „Support of Video-Based lectures with Interactions – Implementation of a first prototype“ is now online available. The slides have alreday been published here.
Abstract:

In general videos have a more or less consuming character without any interaction possibilities. Due to this fact a web-based application is developed which offers different methods of communication and interaction to a certain learning-video. This should help attendees to avoid that they become tired and annoyed. The lecturer is able to use interactions to omit whether learners are able to understand the content of the video. For instance the developed web-application offers the possibility to add multiple-choice-questions at predefined positions. Furthermore there are many different kind of analysis as for example a detailed attention-profile. In this publication the implementation of a first prototype is described as well as a first field study which points out that learners? interactions and engagements increased arbitrarily.

[publication] Developing a Web-Based Question-Driven Audience Response System Supporting BYOD

Our scientific publication about Realfeedback titled „Developing a Web-Based Question-Driven Audience Response System Supporting BYOD“ is now published as part of the Special J.UCS-Issue „Interaction in Massive Courses„.
Abstract:

Question-driven Audience Response Systems (ARSs) are in the focus of research since the 1960s. Since then, the technology has changed and therefore systems have evolved too. This work is about conception and implementation of the web-based ARS RealFeedback which uses the principle of bring your own device (BYOD). A state-of-the-art analysis compares the features of existing web-based ARSs. The most important findings are used for the conception and the implementation of the system. Thinking-aloud tests, and the first usages during lectures confirm that the chosen requirements are very significant and valuable for lecturers.

[masterthesis] Echtzeit-Interaktionsformen für Web-Inhalte

Im Rahmen seiner Masterarbeit hat Josef Wachtler ein System entwickelt, indem er versucht bei Online-Events in der Lehre die Aufmerksamkeit zu erhöhen:

Diese Arbeit dokumentiert die Entwicklung und die Evaluation eines Web-Portals zur Bereitstellung von verschiedenen Interaktionsformen während der Präsentation von beliebigen Echtzeit Web-Inhalten zu festgelegten Zeiten. Da die Interaktion und die Kommunikation als wichtige Bestandteile des E-Learnings angesehen werden, zielt das entwickelte Web-Portal auf eine Verwendung in diesem Bereich, hauptsächlich zur Unterstützung von Vorlesungsübertragungen über das Internet, ab. Somit wird es ermöglicht, dass die bzw. der Vortragende, Fragen an die Teilnehmerinnen und Teilnehmer stellen kann, ähnlich wie mit einem sogenannten Audience Response System. Außerdem ist auch die umgekehrte Richtung der Fragestellung möglich. Dadurch soll die Erhaltung bzw. Erhöhung der Mitarbeit und der Aufmerksamkeit der Teilnehmerinnen und Teilnehmer erreicht werden. Ebenfalls wird eine Berechnung des Aufmerksamkeitsgrads auf Basis der Mitarbeit an den Interaktionsformen, zur Bereitstellung eines Feedbacks, durchgeführt. Die Evaluation zeigt, dass das Potential zur Verbesserung der Aufmerksamkeit durch das Web-Portal gegeben ist, jedoch hängt der erfolgreiche Einsatz stark von der aktiven Unterstützung sowohl durch die Vortragenden als auch von der Mitarbeit durch die Teilnehmerinnen und Teilnehmer ab.

[publication] “How satisfied are you with your MOOC?” – A Research Study on Interaction in Huge Online Courses

Our publication at this year ED-Media Conference in Victoria, Canada about „“How satisfied are you with your MOOC?” – A Research Study on Interaction in Huge Online Courses“ is now online available.
Abstract:

This research work investigates the importance and satisfaction on the level of interaction in MOOCs (Massive Open Online Courses) as perceived by learners and instructors. The study is based on data from online students and instructors of MOOCs. Two web-based surveys were used to collect data. The theoretical basis of the two surveys is the five-step model for interactivity developed by Salmon (2001). Salmon’s model proposed effective e-moderating in five discrete steps (Access and Motivation, Online Socialization, Information Exchange, Knowledge Construction and Development). Findings of the survey revealed that students rated the importance of interactions in MOOCs as highly important. However, they reported negatively the availability of many criteria suggested by Salmon. On the other hand, instructors rated nearly half of Salmon criteria as less important, and consequently did not offer them in their MOOCs. In addition, the study revealed that students and instructors rated a high level of satisfaction in MOOCs. In contrast, some students expressed their less satisfaction of interaction in MOOCs. They revealed their dissatisfaction to that lack of instructor interaction. Instructors suggested that it is impossible for instructor to interact with this huge number of students in MOOCs. As result, some strategies were suggested to enhance instructor interaction with students of MOOCs.
