Introduction
Fast development ICT +
Changes in learner’s behaviour
Educational institutions have toevaluate technological & pedagogical approaches
to (F2F and VLE) learning + teaching

& advances
Technical context (web 2.0)– Web as a platform / applications on the web– Collaborative & interactive applications– User centred model
Pedagogical context (connectivism)– Learning is a constant building of a network– Capacity to learn more imp. than contents– Knowledge rests within the network
Learning 2.0 paradigm– Learner-centred design– Teachers and learners as peers in a network– From traditional learning applications to an
open learning environment
The Open University Of Catalonia (UOC)
• Distance learning – Web based learning (12 years)
• Completely VLE
• 30.000+ students
• Typical student:– >25 y/o– Fully employed– Long forgotten math
Experiences at the UOC.Technological & pedagogical improvements
• Our advantage (VLE): We already “live” inside a computer lab, even if it’s a widely distributed one, so integration of ICT in the classroom is not the problem
• Some experiences at the course of Calculus for Computer Science Students at the UOC
Experiences at the UOC.Technological & pedagogical improvements
• Semantical mark-up mathematical repository on the web (MathML, OpenMath, Ontologies, Learning standards)
– UOC: Web based learning materials with MathML and Wiris
• Interactive math materials and mathematical learning processes
– UOC: interactive Calculus with Wiris
Interaction and mathematical processes
• Problem-solving• Mathematical modelling• Reasoning• Communicating• Making connections (applying maths)• Using tools
Experiences at the UOC.Really web based materials
• Browser support finally allows us to offer web based materials in XHTML + MathML formatLaTeX based authoring + TeX4ht +
• …allow us to embed Wiris applets in order to have a symbolic calculator in the material
• We can teach mathematical processes, and forget about [some] algorithms and memorization
Experiences at the UOC. Interactive math materials
• Case 1: Functions of complex variable
• Case 2: Precalculus
Conclusions & Much More Future Work
Satisfactory experience but it is necessaryimprovement
– New curriculum & methodology in the content/process debate in teaching mathematics
– Interface usability of new tools – Temporal costs of interaction– Students motivation for learning to learn vs.
to learning contents– New assessments and certification systems
To be continued…
