Keynote Presentation:

"E-LEARNING RESEARCH: DOMAIN OR ILLUSION?" by

Dr. Francois Desjardins, Associate Dean, University of Ontario Institute of Technology (UOIT), Canada

Abstract:
Research in e-learning generally remains in a reactive mode. We tend to react to technological developments and to their introduction in educational settings. This is insufficient. We need to move further into a proactive mode, which would then allow us to progress towards a more complete inductive-deductive cycle of reasoning and research. Add to this the constant calls for better and more complete theoretical frameworks for the study of our field, and it is clear that e-learning needs to define itself, clearly, formally and thoroughly.

We need to define the terms and concepts that are specific to our field of study as these would actually also define this field. Which concepts, theories and models are to be considered within the boundaries of e-learning research and which ones are not? What research perspectives, approaches and methodologies are specific to e-learning? Which ones can we adapt from other fields? How does all this formally relate to research and science in other related fields? Collaboration and cooperation are going to be the keys to the establishment of an actual defined field of study, and in this age of social media and social networks, we need to find a manner to first of all actually enter into a dialogue that would result in a set of negotiated definitions of the basic vocabulary as well as of our most complex theories that would not only be the foundation of our discipline, but that would also be recognizable outside our field. This recognition is important in that it is the only way any research can eventually have any impact on the evolution of ideas and practices in any field, even in e-learning.

The intent of this keynote is simply, to collectively consider if e-learning research actually constitutes a distinct field of research activity, a definable domain of knowledge or if it is an illusion.

Extended versions of the best papers were published in the Interactive Technology and Smart Education (ITSE) journal (ISSN:1741-5659), in the IADIS International Journal on WWW/Internet (ISSN: 1645-7641), and also in other selected journals, including journals from Inderscience.

These were the five papers that were considered as the best papers of the e-Learning 2011 Conference:

Best Emergent Technology Paper:

SMART TAGGING TECHNOLOGIES IN PERVASIVE LEARNING ENVIRONMENTS by Ernest Arendarenko and Teemu H. Laine University of Eastern Finland

Abstract:
Smart tagging represents a way of marking an object with a tag carrying an encoded message which can be decoded with an appropriate reader device. As such comparison study of RFID and 2D barcode technologies does not exist, a pervasive mobile learning environment for vocabulary/memory training (MemGame) was developed for 2D barcode and RFID modes and then tested. Participants expected RFID to be faster and more convenient to use than 2D barcode and these views only strengthened after the test. For everyday life scenarios RFID was more preferred. While RFID is clearly preferred smart tagging technology, cheap price and wide availability of reader devices makes 2D barcode still a good alternative. These results might be useful not only for further pervasive learning environment development but also for mobile application development in general where RFID and/or 2D barcodes are utilized. Concrete outcomes of this study are an NFC plugin for MUPE platform and the MemGame.

MONITORING BLENDED LEARNING ENVIRONMENTS BASED ON PERFORMANCE DATA by Markus Dahinden and Lukas Faessler, ETH Zurich, Switzerland

Abstract:
A blended learning course with a large number of students is a complex productive system, and measuring its quality is a demanding task. Traditional educational monitoring is based on pre-course and post-course surveys and often measures students' subjective view of the learning environment. As we know, extrinsic motivational elements often have a greater impact on students' opinion of teaching quality than do didactical principles. We therefore define the quality of a course by the amount of knowledge our students have acquired. In consequence, we prefer to use performance data as the basis for learning evaluation. In this paper we present performance data from 284 students which is stored in an educational data warehouse (eDWH). This data has been linked to process data and status data from the same students. Our findings indicate that performance data can be useful in operationalising the quality of a blended learning environment. Based on three concrete examples, we have been able to illustrate the potential of educational monitoring based on performance data. Our monitoring concept not only allows us to verify the validity of our examinations, but also serves to improve our course and to measure this improvement. The results presented here therefore show that the monitoring of a blended learning environment can indeed be improved using performance data.

A SOCIO-TECHNICAL ASSESSMENT OF TECHNOLOGY USE AND TEACHING PEDAGOGY IN A DISTANCE LEARNING COMMUNITY: AN EMPIRICAL STUDY by Rasha Goumaa, Damnhour University and University of Liverpool Management School, Roula Michaelide and Lisa Anderson, University of Liverpool Management School, UK

Abstract:
The sociocultural model of learning views learning as a social process that is situation dependent. Within the context of distance learning (DL), the adoption of such a model requires distant learners to be active learners. That is the adoption of a teaching pedagogy that promotes collaborative learning through a process of reflection and interaction with content and with peers and tutors. Computer-mediated communication (CMC) is said to be a valuable tool that can enhance collaborative learning while bridging barriers of distance and time to create a common virtual learning space. This study explores how distant learners make sense of their learning experience, how instructors make sense of their teaching experience, whether a particular learning model dominates and furthermore, examines how technology is being used within the context of a part-time MBA program. Adopting an interpretivist stance and deploying a case study methodology, data were collected via semi-structured interviews with students, academic instructors, and a program head. Template analysis was used to analyze data. Our findings show that students felt they had benefitted from their interaction with each other. They also perceived the technology used to create such virtual classrooms valuable when it was properly aligned with what they believed to be an appropriate teaching pedagogy. While in instances of perceived misalignment, technology was deemed of no added value. We argue that, from a socio-technical perspective, the mere existence of the most advanced forms of technology, without thoughtful use and without the necessary facilities and resources being built in to promote a clearly defined and consistent teaching pedagogy, can actually hinder rather than promote effective distance learning.

Best Practical Paper:

SO MUCH TO DO, SO LITTLE TIME: SUPPORTING PROSPECTIVE ELEMENTARY TEACHERS' SENSE OF RATIONAL NUMBERS by Ann LeSage, University of Ontario Institute of Technology (UOIT), Canada

Abstract:
Teachers' understanding of elementary mathematics is an important factor contributing to students' success with mathematics. However, how can this knowledge be nurtured within the time limitations of an 18-week Bachelor of Education program? This paper addresses this question by examining changes in prospective elementary teachers' knowledge of rational numbers after completing a 9-week technology-enhanced elective course and viewing supplemental web-based video clips. The paper describes the course design and video clip format, offers empirical evidence including the impact of moderator variables and proposes implications for teaching practice.

Best Short Paper:

INQUIRY BASED LEARNING CASE STUDIES FOR COMPUTING AND COMPUTING FORENSIC STUDENTS by Jackie Campbell, Leeds Metropolitan University, UK

Abstract:
The purpose of this paper is to describe and discuss the initial evaluation of specifically developed inquiry based learning materials for Computing and Forensic Computing students. Small applications have been developed which require investigation in order to: de-bug applications, analyse data issues and discover 'illegal' behavior. The applications are based around industry case studies and are functioning systems. Applications have been designed with a view to supporting the teaching, learning and assessment within the database curriculum at Leeds Metropolitan University. The students are required to use investigative methods to discover and address the issues. Additionally the exercises are intended to give experience of industrial work such as evaluation, testing and de-bugging of software. The initial feedback is that students like the exercises; they initially may not realize there is anything 'wrong' with the applications and enjoy the investigation and discovery of issues. It has raised their awareness of data quality, data integrity and improved their confidence to question outputs from reports and queries.
