Abstract
We describe an iteratively designed sequence of activities involving the modelling of 1 dimensional collisions between moving objects based on programming in ToonTalk. Students aged 1314 in two settings (London and Cyprus) investigated a number of collision situations, classified into six classes based on the relative velocities and masses of the colliding objects. We describe iterations of the system in which students engaged in a repeating cycle of activity for each collision class: prediction of object behaviour from given collision conditions, observation of a relevant video clip, building a model to represent the phenomena, testing, validating and refining their model, and publishing it – together with comments – on our webbased collaboration system, WebReports. Students were encouraged to consider the limitations of their current model, with the aim that they would eventually appreciate the benefit of constructing a general model that would work for all collision classes, rather than a different model for each class. We describe how our intention to engage students with the underlying concepts of conservation, closed systems and system states was instantiated in the activity design, and how the modelling activities afforded an alternative representational framework to traditional algebraic description.

Additional Information:  This article is a major output from a €1.8 million Europeanfunded threeyear project involving six countries: the main authors were project directors. The paper describes an iterativelydesigned sequence of activities involving the modelling of 1dimensional collisions between moving objects based on programming in ToonTalk. Students aged 1314 in two settings investigated a number of collision situations that were classified into six different classes based on the relative velocities and masses of the colliding objects. The paper details the final iteration of the system in which students engaged in a repeating cycle of activity for each collision class: prediction of object behaviour from given collision conditions, observation of a relevant video clip, building a model to represent the phenomena, testing, validating and refining their model, and publishing it – together with comments – on a speciallydesigned webbased collaboration system, WebReports. The paper shows how students engaged with the underlying concepts of conservation, closed systems and system states, and how the modelling activities afforded an alternative representational framework to traditional algebraic description.
