Ground rules for design principles in creating numeracy learning tools

Be explicit on the definitions, metaphores and images of numeracy you use.

Be explicit about the research base of your design principles

Numeracy

• Work definition: “Numerical competency is the intertwined knowledge, skills and dispositions (attitudes) necessary to adequately and autonomously cope with the quantitative aspects of the world around us.”

Gecijferdheid in beeldImages of Numeracy

People unavoidably have to deal with numbers, structures and patterns

The quantitative side of the world around us requires a much richer and multifaceted repertoire

This booklet aims to create richer and more colourful images of numeracy

Research base:- my own research

- existing literature

Conclusions• Students show a much more sophisticated

mathematical competence when they have an product at hand.

• Students use gestures to support their mathematical reasoning.

• Students use a very limited mathematical vocabulary.

• Students use technical language regularly.

Design principles for our multimedia tool for numeracy education• Every problem is directly related to a real situation• The context of the problem is visualized in

photographs or video clips• The context is NOT generated by text

• Every problem must be imaginable as a real and relevant question

• Answering the posed problem demands some numerate action

• Building up complexity is in the complexity of the contexts and not in the complexity of the mathematical concepts.
