Students & researchers from UK, Italy, Sweden, Bulgaria, Portugal, Cyprus. creating new ways of representing and expressing mathematical and scientific knowledge in European communities of young learners ( 10 – 14 ). Our aim was to transform the web into a medium in which European students collaboratively construct and critique each others' evolving knowledge and working models .

… based research Design based research is a methodology for the study of function. Often referred to as design research or design experiments. Concerned with the design of learning processes, taking account of the involved complexities, multiple levels and contexts of educational settings. The primary aim is to develop domain-specific theories in order to understand the learning process. (Mor & Winters, 2006)

Design patterns [describe] a problem which occurs over and over again in our environment, and then describes the core of the solution to that problem, in such a way that you can use this solution a million times over, without ever doing it the same way twice (Alexander et al., 1977)

example: activity nodes Design problem Community facilities scattered individually through the city do nothing for the life of the city. Design solution Create nodes of activity throughout the community, spread about 300 yards apart. http://www.uni-weimar.de/architektur/InfAR/lehre/Entwurf/Patterns/030/ca_030.html

Mathematical game pieces Mathematical content is often injected artificially into games or other activities, as sugar-coating . This has a dual effect of ruining the game and alienating the mathematics. By contrast, for many mathematicians, mathematics is the game. Problem / Intent Context Games for mathematical learning.

Games for mathematical learning.

Mathematical game pieces (II) Identify an element of the mathematical content you wish to address in this game. Find a visual, animated or tangible representation of this element which is consistent with the game metaphors. Design your game so that these objects have clear purpose and utility as game elements in the gameplay structure.

Soft scaffolding Technology should be designed to scaffold learners' progress, but an interface that is too rigid impedes individual expression, exploration and innovation. Problem / Intent Context Interactive learning interface

Technology should be designed to scaffold learners' progress, but an interface that is too rigid impedes individual expression, exploration and innovation.

Soft scaffolding (II) Provide scaffolding which can easily be overridden by the learner or by the instructor. Let the scaffolding be a guideline, a recommendation which is easier to follow than not, but leave the choice in the hands of the learner. For example: When providing a multiple-selection interface, always include an open choice, which the user can specify (select 'other' and fill in text box). When the user is about to stray off the desired path of activity, warn her, ask for confirmation, but do not block her.

Narrative spaces Constructing narrative is a fundamental mechanism for making sense of events and observations. To leverage it, we must give learners opportunities to express themselves in narrative form. Problem / Intent Context Digital environments for collaborative learning.

Constructing narrative is a fundamental mechanism for making sense of events and observations. To leverage it, we must give learners opportunities to express themselves in narrative form.

Narrative spaces (II) Provide learners with a narrative space: a medium, integrated with the activity design, which allows learners to express and explore ideas in a narrative form: Allow for free-form text, e.g. by supporting soft scaffolding . Choose narrative representations when possible. Mark narrative elements in the medium: Clearly mark the speaker / author, to support a sense of voice. Date contributions to support temporal sequentiality ('plot'). Use semi-automated meta-data to provide context.

Objects to talk with Natural discourse makes extensive use of artefacts: we gesture towards objects that mediate the activity to which the discussion refers. This dimension of human interaction is often lost in computerized interfaces. Problem / Intent interfaces which allow learners to converse about a common activity. Context

Natural discourse makes extensive use of artefacts: we gesture towards objects that mediate the activity to which the discussion refers. This dimension of human interaction is often lost in computerized interfaces.

Objects to talk with (II) Learning activities often involve the use or construction of artefacts. When providing tools for learners to discuss their experience, allow them to easily include these artefacts in the discussion. If the activity is mediated by or aims to produce digital artefacts, then the discussion medium should allow embedding of these artefacts. The medium should support a visual (graphical, symbolic, animated or simulated) 1:1 representation of these objects.

Objects to talk with: Example This is the real graph that was produced by the cumulate total of the halving-a-number robot. It looks like the top of my graph but I made the fatal mistake of thinking it started at zero. I also said it wouldn’t go over 100, which was very wrong.
