This volume collects some of the papers presented at the 16th IARTEM Conference held in Florence in April 2022. It was a 'difficult conference', held at a time when the pandemic was still present, and therefore an important opportunity to resume a dialogue that seemed to have been interrupted. The richness of the content, which is the result of the reflections of authors from all over the world, allows us to provide a precise scenario of the research state of art in the field of textbooks and digital resources for teaching.
