Towards a personalized task selection model with shared instructional control

Corbalan, G., Kester, L., & Van Merriënboer, J .J. G. (2006). Towards a personalized task selection model with shared instructional control. Instructional Science, 34 , 399-422.Modern education emphasizes the need to flexibly personalize learning tasks to individual learners. This article discusses a personalized task-selection model with shared instructional control based on two current tendencies for the dynamic sequencing of learning tasks: (1) personalization by an instructional agent which makes sequencing decisions on the basis of learner’s expertise, and (2) personalization by the learner who is given control over –final—task selection. The model combines both trends in a model with shared instructional control. From all available learning tasks, an instructional agent selects a subset of tasks based on the learner’s performance scores and invested mental effort (i.e., system-control). Subsequently, this subset is presented to the learner who makes the final decision (i.e., learner control). A computer-assisted instructional program has been developed to put the model into practice and preliminary results are discussed. The model can be used to increase the efficiency and effectiveness of instruction and to make it more appealing by providing the learner an optimal level of control over task selection

Creative Relations

Through reporting about a project with male home carers, I’m going to present some of the interactions which took place between myself (as the artist) and the participants as we got to know each other, and became part of each other’s lives. The text takes the form of a series of extracts taken directly from my own personal journals followed by a commentary on each. These have been selected to highlight the similarities between Ingold’s descriptions of creativity and Kester’s model for a dialogical aesthetic, which highlights key points in the engagement processes of a socially engaged artist. These reflective notes, made while the experiences were still fresh in my mind, help to illustrate the impact not only on the participants but also upon the artist as a participant in the social process

Learner-controlled selection of tasks with different surface and structural features: Effects on transfer and efficiency

Surface task features are more salient than structural task features and thus easier to recognize for novices. It is predicted that the more salient the task features the better learners can choose personally relevant and varied tasks, which enhances learning transfer. To investigate this prediction, a 2 x 2 factorial experiment with 72 participants studied the effects of control over tasks that differ in their surface features (learner, program) and in their structural features (learner, program). Learner control over the selection of tasks with salient surface features enables learners to select personally relevant and varied tasks. This is believed to yield higher effectiveness (i.e., higher near and far transfer test performance) as well as higher efficiency (i.e. higher transfer test performance combined with lower associated mental effort). Learner control over the selection of tasks with non-salient structural features does not enable learners to select personally relevant and varied tasks and is therefore not expected to yield beneficial effects on learning. The results show positive effects of learner control over the selection of tasks with salient surface features for efficiency on the far transfer test but not for effectiveness. Theoretical and practical implications are discussed

NetServ: Early Prototype Experiences

This paper describes a work-in-progress to demonstrate the feasibility of integrating services in the Internet core. The project aims to reduce or eliminate so called ossification of the Internet. Here we discuss the recent contributions of two of the team members at Columbia University. We will describe experiences setting up a Juniper router, running packet forwarding tests, preparing for the GENI demo, and starting prototype 2 of NetServ

Constellations of identity: place-ma(r)king beyond heritage

This paper will critically consider the different ways in which history and belonging have been treated in artworks situated in the Citadel development in Ayr on the West coast of Scotland. It will focus upon one artwork, Constellation by Stephen Hurrel, as an alternative to the more conventional landscapes of heritage which are adjacent, to examine the relationship between personal history and place history and argue the primacy of participatory process in the creation of place and any artwork therein. Through his artwork, Hurrel has attempted to adopt a material process through which place can be created performatively but, in part due to its non-representational form, proves problematic, aesthetically and longitudinally, in wholly engaging the community. The paper will suggest that through variants of ‘new genre public art’ such as this, personal and place histories can be actively re-created through the redevelopment of contemporary urban landscapes but also highlight the complexities and indeterminacies involved in the relationship between artwork, people and place
