This chapter aims to deepen the idea that one of the crucial aspects of algebraic problem solving is the transformation of the mathematical structure of the problem in order to be able to manage it better, and that anticipation allows the process of transformation to be directed towards simplifying and resolving the task. Different cases of the transformation of the problem (without, before and...

This paper describes the ongoing work in the design and implementation of a program transformation system for educational purposes. The system is based on Asf+Sdf for the implementation of the application of transformation rules and on Seal for the implementation of the user interface. The transformation rules are given in a mixture of CIP-L and Clean: Disciplean. The Disciplean transformation ...

The extremely rapid expansion of open educational resource (OER) initiatives and the millions of learners they attract can be understood as an indicator of an emerging revolution in education and learning. This paper describes recent developments in this area and develops conceptual foundations for studies and policies on OER. We describe four different types of OER, locate these in a field of ...
