The 13th International Conference on Technology in Mathematics Teaching – ICTMT 13 is organized by the Ecole Normale Supérieure de Lyon and the University Lyon 1. It was held in Lyon, France, 3 to 6 July, 2017.

This biennial conference is the thirteenth of a series which began in Birmingham, UK, in 1993, under the influential enterprise of Professor Bert Waits from Ohio State University. The last conference was held in Faro, Portugal, in 2015.

The ICTMT conference series is unique in that it aims to bring together lecturers, teachers, educators, curriculum designers, mathematics education researchers, learning technologists and educational software designers, who share an interest in improving the quality of teaching and learning, and eventually research, by effective use of technology. It provides a forum for researchers and practitioners in this field to discuss and share best practices, theoretical know-how, innovation and perspectives on educational technologies and their impact on the teaching and learning of mathematics, as well as on research approaches.
