The Web Geometry Laboratory
The Web Geometry Laboratory (WGL) is a blended-learning Web-environment forgeometry. The main features of the Web Geometry Laboratory (v1.4) are:
A repository of geometric problems: each user has his/her own list of constructions;
A permissions system allowing the sharing (or not) of each construction between usersand groups;

The Web Geometry Laboratory
The Web Geometry Laboratory (WGL) is a blended-learning Web-environment forgeometry. The main features of the Web Geometry Laboratory (v1.4) are:
An collaborative module, where a given geometric task can be worked collaborativelyby a group of users (exchanging textual (chat) and geometrical information);

Adaptive Strategies in WGL— Students
To be able to build individual students profiles and/or individuallearning paths, the system collects geometric information aboutthe students’ interactions when in the regular, stand-alone, mode.

Adaptive Strategies in WGL— TeachersThe teacher is able to see the work done, from the first step to thelast step: step by step, in motion, normal or faster speed, to pauseand to resume.
Analysing the steps done by the student to solve the task, theteacher can assert the student’s van Hiele levels of geometricknowledge.

Current Work
Case studies in Portugal and Serbia
The development work currently being done regards theconstruction of a learning path editor
This editor will allow the teacher to build learning pathsdifferentiated by students’ profiles
Each learning paths will be a (non-)linear sequence of tasks to besolved by each student

Future Work
The WGL platform will include in future stages of development a
geometric automated theorem prover to be used in the automatic,
or semi-automatic construction of the students profiles, and in the
learning process
