JuxtaLearn D3.2 Performance Framework

This deliverable, D3.2, for Work Package 3 incorporating the pedagogy from WP2 and orchestration factors mapped in D3.1 reviews aspects of performance in the context of participative video making. It reviews literature on curiosity and engagement characteristics of interaction mechanisms for public displays and anticipates requirements for social network analysis of relevant public videos from WP6 task 6.3. Thus, to support JuxtaLearn performance it proposes a reflective performance framework that encompasses the material environment and objects required, the participants, and the knowledge needed

A Study of Information Fragment Association in Information Management and Retrieval Applications

As we strive to identify useful information sifting through the vast number of resources available to us, we often find that the desired information is residing in a small section within a larger body of content which does not necessarily contain similar information. This can make this Information Fragment difficult to find. A Web search engine may not provide a good ranking to a page of unrelated content if it contains only a very small yet invaluable piece of relevant information. This means that our processes often fail to bring together related Information Fragments. We can easily conceive of two Information Fragments which according to a scholar bear a strong association with each other, yet contain no common keywords enabling them to be collocated by a keyword search.This dissertation attempts to address this issue by determining the benefits of enhancing information management and retrieval applications by providing users with the capability of establishing and storing associations between Information Fragments. It estimates the extent to which the efficiency and quality of information retrieval can be improved if users are allowed to capture mental associations they form while reading Information Fragments and share these associations with others using a functional registry-based design. In order to test these benefits three subject groups were recruited and assigned tasks involving Information Fragments. The first two tasks compared the performance and usability of a mainstream social bookmarking tool with a tool enhanced with Information Fragment Association capabilities. The tests demonstrated that the use of Information Fragment Association offers significant advantages both in the efficiency of retrieval and user satisfaction. Analysis of the results of the third task demonstrated that a mainstream Web search engine performed poorly in collocating interrelated fragments when a query designed to retrieve the one of these fragments was submitted. The fourth task demonstrated that Information Fragment Association improves the precision and recall of searches performed on Information Fragment datasets.The results of this study indicate that mainstream information management and retrieval applications provide inadequate support for Information Fragment retrieval and that their enhancement with Information Fragment Association capabilities would be beneficial

Proceedings of the Inaugural Meeting ofAIS SIGPrag

The Special Interest Group on Pragmatist IS Research (SIGPrag) was approved by the Association for InformationSystems (AIS) council at its June 2008 meeting in Gallway. The motivation for this initiative is the growingrecognition of the importance of theorizing the IT artifact and its organizational and societal context from apragmatic and action-oriented perspective. SIGPrag\u27s mission is to provide a much-needed centre of gravity and tofacilitate exchange of ideas and further development of this area of IS scholarship.In summary, pragmatist IS research rests on the following set of assumptions: * Human life is a life of activity.* Humans do things that effect changes in their environment and/or within themselves.* Doing permeates thinking, conceptualizations and language use.* Human consciousness is a practical one that is in constant interplay with interventive, investigative, andevaluative actions.* Practical consciousness is formed by experience from previous actions and participation in social contexts.* IT and information systems are fundamentally symbolic language systems.* Linguistically expressed collective presuppositions, norms and categories (such as those embedded in ITand information systems) serve human activity and life.* The true value of IT and information systems lies in their potential to support human communication andcollaboration central to human activity and life.For more information about SIGPrag, its mission and current activities, please visit http://www.sigprag.org/The inaugural meeting of SIGPrag is to be held in Paris on Dec 14, 2008, in conjunction with the InternationalConference on Information Systems (ICIS). The meeting will consist of two parts, a scientific meeting and abusiness meeting. For the scientific meeting a call for position papers was issued in the summer of 2008, whichresulted in the following papers being selected for presentation:• What Kind of Pragmatism in Information Systems Research? by Göran Goldkuhl.• Pragmatic Approach in IS Projects Grounded on Recognised Frameworks by Raija Halonen.• Co-Design as Social Constructive Pragmatism by Mikael Lind, Ulf Seigerroth, Olov Forsgren, and AndersHjalmarsson.• Pragmatism and Information Systems (IS): Neurophilosophical approach by Garikoitz Lerma Usabiagaand Francesc Miralles.• Sustainability Communication: A role for IT and IS in relating business and Society by Mark Aakhus andPaul Ziek.• Managing Ambiguity while Reducing Uncertainty by Gianni Jacucci and Mike Martin.• A Pragmatic Conception of Service Encounters by Mikael Lind and Nicklas Salomonson.• Making the Web More Pragmatic: Exploring the Potential Of Some Pragmatic Concepts For IS ResearchAnd Development by Jens Allwood and Mikael Lind.• Introducing Human in Complex System: A Cognitive Pragmatics Based Model by G. Lortal.• The Pragmatic Web: An Application View by Mareike Schoop.• Design Research from a Communicative Perspective: How to Design Things with Words by Hans Weigand.• Representation and Correspondence: On the Validity of the Representation Assumption in InformationSystem Design by Pär J. Ågerfalk and Owen Eriksson.• Habermas’ theory in action by Jan L.G. Dietz.• Challenges to Information Systems Development by Roland Kaschek.The idea behind this inaugural meeting was to bring together people that share an affinity with pragmatist ISresearch and to initiate a scientific discussion about the role of pragmatist research in IS. We certainly hope that thisdiscussion will continue over the years to come. The papers are freely available for download athttp://www.sigprag.org

The Value of New Scientific Communication Models for Chemistry

This paper is intended as a starting point for discussion on the possible future of scientific communication in chemistry, the value of new models of scientific communication enabled by web based technologies, and the necessary future steps to achieve the benefits of those new models. It is informed by a NSF sponsored workshop that was held on October 23-24, 2008 in Washington D.C. It provides an overview on the chemical communication system in chemistry and describes efforts to enhance scientific communication by introducing new web-based models of scientific communication. It observes that such innovations are still embryonic and have not yet found broad adoption and acceptance by the chemical community. The paper proceeds to analyze the reasons for this by identifying specific characteristics of the chemistry domain that relate to its research practices and socio-economic organization. It hypothesizes how these may influence communication practices, and produce resistance to changes of the current system similar to those that have been successfully deployed in other sciences and which have been proposed by pioneers within chemistry.National Science Foundation, Microsof

MOOClm: Learner Modelling for MOOCs

Massively Open Online Learning systems, or MOOCs, generate enormous quantities of learning data. Analysis of this data has considerable potential benefits for learners, educators, teaching administrators and educational researchers. How to realise this potential is still an open question. This thesis explores use of such data to create a rich Open Learner Model (OLM). The OLM is designed to take account of the restrictions and goals of lifelong learner model usage. Towards this end, we structure the learner model around a standard curriculum-based ontology. Since such a learner model may be very large, we integrate a visualisation based on a highly scalable circular treemap representation. The visualisation allows the student to either drill down further into increasingly detailed views of the learner model, or filter the model down to a smaller, selected subset. We introduce the notion of a set of Reference learner models, such as an ideal student, a typical student, or a selected set of learning objectives within the curriculum. Introducing these provides a foundation for a learner to make a meaningful evaluation of their own model by comparing against a reference model. To validate the work, we created MOOClm to implement this framework, then used this in the context of a Small Private Online Course (SPOC) run at the University of Sydney. We also report a qualitative usability study to gain insights into the ways a learner can make use of the OLM. Our contribution is the design and validation of MOOClm, a framework that harnesses MOOC data to create a learner model with an OLM interface for student and educator usage

#MPLP: a Comparison of Domain Novice and Expert User-generated Tags in a Minimally Processed Digital Archive

The high costs of creating and maintaining digital archives precluded many archives from providing users with digital content or increasing the amount of digitized materials. Studies have shown users increasingly demand immediate online access to archival materials with detailed descriptions (access points). The adoption of minimal processing to digital archives limits the access points at the folder or series level rather than the item-level description users\u27 desire. User-generated content such as tags, could supplement the minimally processed metadata, though users are reluctant to trust or use unmediated tags. This dissertation project explores the potential for controlling/mediating the supplemental metadata from user-generated tags through inclusion of only expert domain user-generated tags. The study was designed to answer three research questions with two parts each: 1(a) What are the similarities and differences between tags generated by expert and novice users in a minimally processed digital archive?, 1(b) Are there differences between expert and novice users\u27 opinions of the tagging experience and tag creation considerations?, 2(a) In what ways do tags generated by expert and/or novice users in a minimally processed collection correspond with metadata in a traditionally processed digital archive?, 2(b) Does user knowledge affect the proportion of tags matching unselected metadata in a minimally processed digital archive?, 3(a) In what ways do tags generated by expert and/or novice users in a minimally processed collection correspond with existing users\u27 search terms in a digital archive?, and 3(b) Does user knowledge affect the proportion of tags matching query terms in a minimally processed digital archive? The dissertation project was a mixed-methods, quasi-experimental design focused on tag generation within a sample minimally processed digital archive. The study used a sample collection of fifteen documents and fifteen photographs. Sixty participants divided into two groups (novices and experts) based on assessed prior knowledge of the sample collection\u27s domain generated tags for fifteen documents and fifteen photographs (a minimum of one tag per object). Participants completed a pre-questionnaire identifying prior knowledge, and use of social tagging and archives. Additionally, participants provided their opinions regarding factors associated with tagging including the tagging experience and considerations while creating tags through structured and open-ended questions in a post-questionnaire. An open-coding analysis of the created tags developed a coding scheme of six major categories and six subcategories. Application of the coding scheme categorized all generated tags. Additional descriptive statistics summarized the number of tags created by each domain group (expert, novice) for all objects and divided by format (photograph, document). T-tests and Chi-square tests explored the associations (and associative strengths) between domain knowledge and the number of tags created or types of tags created for all objects and divided by format. The subsequent analysis compared the tags with the metadata from the existing collection not displayed within the sample collection participants used. Descriptive statistics summarized the proportion of tags matching unselected metadata and Chi-square tests analyzed the findings for associations with domain knowledge. Finally, the author extracted existing users\u27 query terms from one month of server-log data and compared the generated-tags and unselected metadata. Descriptive statistics summarized the proportion of tags and unselected metadata matching query terms, and Chi-square tests analyzed the findings for associations with domain knowledge. Based on the findings, the author discussed the theoretical and practical implications of including social tags within a minimally processed digital archive
