Athens. A test to assess the mathematical skills of primary and secondary school students with the objective of helping them fill in the gaps or helping them increase their performance. The test was developed by a group of mathematicians and psychologists from the Universities of Pisa and Athens thanks to a recently published study on the “Austrlian Journal of Learning Difficulties”. “The research is the result of an international collaboration that started during a conference in San Marino organised by the ‘European Dyslexia Association’ where I met Giannis N. Karagiannakis, a PhD candidate from the Department of Special Education and Psychology of the University of Athens. We compared our studies in the field of learning disabilities in mathematics” Anna Baccaglini-Frank, a mathematician from the University of Pisa. (9colonne)
