Collaborative learning with a wiki: Differences in perceived usefulness in two contexts of use

This paper investigates the potential of a wiki (FlexWiki) to support collaborative authoring of web resources in authentic coursework by two different sets of education students at different stages of their professional development. Research questions included: (1) how the selected wiki could be blended with curriculum activities and existing technologies to complete collaborative tasks; (2) student and tutor expectations concerning collaborative learning and whether these expectations were met; (3) the barriers and enablers of using the wiki and perceptions of the task‐technology fit. Key findings included that tutors and students were able to use the wiki to complete tasks; tutors and students were positive about learning outcomes but collaboration was not as co‐constructive as hoped for; there were tensions between expectations of collaboration and assessment practices that affected how students collaborated; differences between participants in their group interaction, degree of co‐presence and familiarity with technology led to differences in perceptions of usefulness and actual wiki use; and version‐tracking data from the wiki proved unreliable on its own for gaining insights into actual collaborative processes. These findings suggest the importance of considering detailed local contexts of use when deciding to adopt new tools for supporting collaboration.

Practices with technology: learning at the boundary between study and work

A study of part‐time student experience of university courses delivered using a range of technologies found that information and communication technology enabled students to move between study and work experience to the benefit of their learning in both contexts. Technology‐based study activities enabled students to participate in learning both as a student and as a member of a practice or work context. Given the increasingly pressured lives of all students in higher education and their aspirations for employment after graduation, this suggests that we would benefit from taking their relationship to work and professional practice into account more directly, in deciding how to integrate technology into their study experience. Teacher conceptions of technology as a tool primarily for information delivery and discussion need to expand to recognize that it can be used to construct learning experiences situated in roles, skills and interactive environments that enhance students' ability to make transitions across the boundaries between contexts of study and work.

QUESTO: Interactive Construction of Objective Functions for Classification Tasks

Building effective classifiers requires providing the modeling algorithms with information about the training data and modeling goals in order to create a model that makes proper tradeoffs. Machine learning algorithms allow for flexible specification of such meta-information through the design of the objective functions that they solve. However, such objective functions are hard for users to specify as they are a specific mathematical formulation of their intents. In this paper, we present an approach that allows users to generate objective functions for classification problems through an interactive visual interface. Our approach adopts a semantic interaction design in that user interactions over data elements in the visualization are translated into objective function terms. The generated objective functions are solved by a machine learning solver that provides candidate models, which can be inspected by the user, and used to suggest refinements to the specifications. We demonstrate a visual analytics system QUESTO for users to manipulate objective functions to define domain-specific constraints. Through a user study we show that QUESTO helps users create various objective functions that satisfy their goals.

Powering E-Learning In the New Millennium: An Overview of E-Learning and Enabling Technology

In today's new economy characterized by industrial change, globalization, increased intensive competition, knowledge sharing and transfer, and information technology revolution, traditional classroom education or training does not always satisfy all the needs of the new world of lifelong learning. Learning is shifting from instructor-centered to learner-centered, and is undertaken anywhere, from classrooms to homes and offices. E-Learning, referring to learning via the Internet, provides people with a flexible and personalized way to learn. It offers learning-on-demand opportunities and reduces learning cost. This paper describes the demands for e-Learning and related research, and presents a variety of enabling technologies that can facilitate the design and implementation of e-Learning systems. Armed with the advanced information and communication technologies, e-Learning is having a far-reaching impact on learning in the new millennium.
