The latest milestone release (migensystem-1-8479b available as a zip file from our google code repository) contains significant changes from the December release.
The main change is an attempt to reduce the space occupied by the General Model by including it in the Activity Document. In specific tasks this means that it can be included above or below the task presentation. In all other cases, users can construct their own Activity Documents.
This change also affects the way the students’ work area can be presented. It now includes the “Play Button” as well and therefore students can check the generality of their models directly in their working area. Other implications of this change include:
- the General Model can be resized and/or zoomed accordingly
- values of unlocked numbers are shown in the General Model as soon as they are unlocked (the window displays unnamed unlocked numbers and named unlocked numbers separately)
- the Model Rule appears in an equation in the General Model and named unlocked numbers appear simply as their names.
Because of these significant pages we wrote more detailed descriptions in the Using MiGen pages (note also a new video from the MiGen team “Learn eXpresser in less than 5 minutes“ that introduces eXpresser and incorporates the changes to the ‘General Model’ mentioned above).
You feedback and ideas for future versions are welcome.
Other changes include the following:
- users can change tasks without closing eXpresser
- documents/pages can also be saved and loaded without closing eXpresser
There are also a lot of change in the teacher tools
- classroom dynamics tool, grouping tool, student tracker, goal achievement
These were demonstrated at a PGCE session at the Institute of Education.

Best PhD student paper
The paper “Adaptive Modelling of Users’ Strategies in Exploratory Learning Using Case-Based Reasoning” by M. Cocea, S. Gutierrez-Santos and G.D. Magoulas, which describes work done in the context of the MiGen project, won the best PhD student paper award at the 14th International Conference on Knowledge-Based and Intelligent Information & Engineering Systems (KES 2010), Cardiff, Wales, UK, 8-10 September 2010.
CERME Distinguished Lecturer Series
As part of the Centre for Research in Mathematics and Science Education’s Distinguished Lecturer Series, Richard Noss and Celia Hoyles represented the MiGen team and presented on ‘Mathematics at Work: A Need for New Mathematical Literacies” at the University of San Diego.

The latest milestone release (r7195 – available as a zip file from our google code repository) includes the following changes:
- Pre-defined activities for learning eXpresser progressively (feel free to contact us for activity manuals lesson plans). If you want to play with eXpresser without a certain activity choose the Default one from the drop down menu.
- A full-fledged activitity (called TrainTrack) that asks for students to make a model, reflect on their goals, and share their model and rules with other students. The system also demonstrates the design of intelligent support that can be provided for these activities
Since summer we have been working a lot on the internal architecture of the system, so not a lot of visible changes in eXpresser apart from:
- The design of the negative tiles has now changed to Removable Patterns. All patterns can now be either added or removed to the canvas thus allowing the creation of complex patterns with overlaps
- Several bugs were fixed. In particular patterns of patterns now behave more consistently both in “My Model” and the “General Model”
- As always some bugs were fixed – but feel free to report anything you find
This release also comes with a server and teacher tools but these are still experimental. Feel free to contact us for more info.
