Teaching and learning mathematics: resources and obstables, Proceedings of CIEAEM 67, Quaderni di ricerca didattica, 25-2

The CIEAEM 67 conference was held in Aosta, Italy, from 21st to 24th July 2015 and successfully involved more than 120 participants from all over the world. Researchers, teachers, educators, and students from 20 countries (10 non-European) met to discuss, in a collaborative and inspiring environment, the most prominent problems, obstacles and resources in mathematics education; they also presented their latest research findings in the several conference activities: plenary talks, a round table, working groups, workshops, and poster presentations (forum of ideas). As in previous CIEAEM meetings, Working Groups constituted the beating heart of the conference, allowing the participants to fruitfully discuss in critical and constructive ways, in the true CIEAEM spirit, research studies and approaches from different perspectives on the conference theme: Teaching and learning mathematics: resources and obstacles. There were five Working Groups, each discussing between 11 and 16 papers, and addressing the conference theme from complementary viewpoints (see the Discussion Paper), under the guidance of the group animators. The conference schedule allowed time also to deepen the plenary talks in the dedicated “Meet the plenary speaker” sessions, and to engage participants in workshops, where actual dialogue between research and practice could be fostered. This volume contains the final versions of the 85 papers presented during the conference, and revised by the authors, including the suggestions which emerged in the intense discussions in Aosta. Specifically, the volume chapters contain - 3 Plenary talks, - 4 contributions related to a Round Table on assessment, - 66 papers presented and discussed in the 5 Working Groups in parallel sessions, - 5 papers on the Workshops organized during the conference, - 6 papers presenting Posters.
