Project Aims

The MiGen project is designing and developing a pedagogical and technical environment to support 11-14 year-old students in their learning of mathematical generalisation. The system comprises a microworld, the eXpresser; an intelligent tool, the eGeneraliser; and a suite of teacher assistance tools. Using the eXpresser, students tackle generalisation tasks set by their teacher. As they do so, the eGeneraliser provides personalised feedback adapted to the learning trajectories of each student. Teachers are presented with summary views of students' progress through the Student Tracking and Classroom Dynamics tools, which aim to help them provide appropriate interventions and guidance. Also, students are able to view each others' constructions and compare, critique and discuss them.  

Current status

Within the eXpresser (see Fig. 1), students use building blocks to construct ‘generalised patterns' which they subsequently colour. Crucially, they use variables to help specify how many tiles of each colour are needed. Figure 2 shows one current representation of student tracking; as students work in the eXpresser, this visualisation displays the occurrence of various landmarks to assist the teacher.  All the MiGen tools are integrated into a lightweight server-client architecture based on REST (REpresentation State Transfer). This facilitates use of the system during the lifetime of the project and also contributes to the sustainability of the system's use in schools after the project has finished. The integrated system will be used from July 2010 in various local schools where the system's efficacy as a whole will be investigated.
