Designing Interfaces to Support Collaboration in Information Retrieval

Information retrieval systems should acknowledge the existence of collaboration in the search process. Collaboration can help users to be more effective in both learning systems and in using them. We consider some issues of viewing interfaces to information retrieval systems as collaborative notations and how to build systems that more actively support collaboration. We describe a system that embodies just one kind of explicit support; a graphical representation of the search process that can be manipulated and discussed by the users. By acknowledging the importance of other people in the search process, we can develop systems that not only improve help-giving by people but which can lead to a more robust search activity, more able to cope with, and indeed exploit, the failures of any intelligent agents used

Assessment of the Foster Care Pilot Project in Albania

CELCIS was contracted by UNICEF Albania in August, 2013, to carry out an evaluation of the pilot foster care project (FCPP). UNICEF had contributed to funding for a foster care project which operated in Tirana and Shkodra. The operational aspects of the projects were run by two non-governmental organisations (NGOs) called Bethany Social Services (BSS) and Every Child Albania (EC). The consultants carried out a brief literature review and a desk review of relevant documentation. They also undertook a period of fieldwork in Albania, interviewing key stakeholders and carrying out observational visits

Evaluating the development of wearable devices, personal data assistants and the use of other mobile devices in further and higher education institutions

This report presents technical evaluation and case studies of the use of wearable and mobile computing mobile devices in further and higher education. The first section provides technical evaluation of the current state of the art in wearable and mobile technologies and reviews several innovative wearable products that have been developed in recent years. The second section examines three scenarios for further and higher education where wearable and mobile devices are currently being used. The three scenarios include: (i) the delivery of lectures over mobile devices, (ii) the augmentation of the physical campus with a virtual and mobile component, and (iii) the use of PDAs and mobile devices in field studies. The first scenario explores the use of web lectures including an evaluation of IBM's Web Lecture Services and 3Com's learning assistant. The second scenario explores models for a campus without walls evaluating the Handsprings to Learning projects at East Carolina University and ActiveCampus at the University of California San Diego . The third scenario explores the use of wearable and mobile devices for field trips examining San Francisco Exploratorium's tool for capturing museum visits and the Cybertracker field computer. The third section of the report explores the uses and purposes for wearable and mobile devices in tertiary education, identifying key trends and issues to be considered when piloting the use of these devices in educational contexts

Information scraps: how and why information eludes our personal information management tools

In this paper we describe information scraps -- a class of personal information whose content is scribbled on Post-it notes, scrawled on corners of random sheets of paper, buried inside the bodies of e-mail messages sent to ourselves, or typed haphazardly into text files. Information scraps hold our great ideas, sketches, notes, reminders, driving directions, and even our poetry. We define information scraps to be the body of personal information that is held outside of its natural or We have much still to learn about these loose forms of information capture. Why are they so often held outside of our traditional PIM locations and instead on Post-its or in text files? Why must we sometimes go around our traditional PIM applications to hold on to our scraps, such as by e-mailing ourselves? What are information scraps' role in the larger space of personal information management, and what do they uniquely offer that we find so appealing? If these unorganized bits truly indicate the failure of our PIM tools, how might we begin to build better tools? We have pursued these questions by undertaking a study of 27 knowledge workers. In our findings we describe information scraps from several angles: their content, their location, and the factors that lead to their use, which we identify as ease of capture, flexibility of content and organization, and avilability at the time of need. We also consider the personal emotive responses around scrap management. We present a set of design considerations that we have derived from the analysis of our study results. We present our work on an application platform, jourknow, to test some of these design and usability findings

A Pilot Evaluation Study Using LectureTools to Enhance Interactivity in Classroom-Based Teaching in a Project Management Course

With students’ ownership of laptops and mobile devices increasing, there exists an opportunity to harness their use to support interactivity within the traditional classroom. Two educators, motivated to enhance interactivity in a two-day project management course at a UK university, trialled LectureTools, a cloud-based audience-response system. To assess potential benefits to learning and teaching, as well as identifying accompanying challenges, an evaluation study was carried out comprising a range of data sources. These included observation of a LectureTools-based lecture and a student questionnaire followed by a focus group discussion with a subset of students about their experiences throughout the two days. Interviews with both teachers were also conducted, adding to the evaluation research data and giving them an opportunity to reflect on their teaching practice. All participants recognised the benefits of LectureTools in promoting student engagement, learning and discussion while students acknowledged the distractive potential of having laptops in the lecture theatre. Efforts are required by educators to ensure that the interactive potential of laptops in classrooms to enhance learning and teaching is supported while controlling the potential for distraction. Future research is needed to ascertain the impact of using LectureTools on approaches to learning and teaching

Continuity in cognition

Designing for continuous interaction requires designers to consider the way in which human users can perceive and evaluate an artefact’s observable behaviour, in order to make inferences about its state and plan, and execute their own continuous behaviour. Understanding the human point of view in continuous interaction requires an understanding of human causal reasoning, of the way in which humans perceive and structure the world, and of human cognition. We present a framework for representing human cognition, and show briefly how it relates to the analysis of structure in continuous interaction, and the ways in which it may be applied in design

Learning outcome dependency on contemporary ICT in the New Zealand middle school classroom

Often studies of children's technology use in the classroom is internally focused and small scale. This study attempts a globalised exploratory overview of an entire New Zealand middle school to understand the technology usages across a range of curriculum and learning outcomes. Observations of the use of technology in the classroom during eight different lessons were conducted followed by structured-open-ended interviews. From our classroom observations and through teacher interviews, we have been able to identify three levels of the dependency of learning outcome on contemporary-ICT
