We look forward to honouring them at ICME-13 in Hamburg in 2016.

The early ICMEs acted as catalysts for new ideas that have their roots in important events that took place in the 1950s and 1960s. As a consequence new issues found their place in the international discussion on mathematics education and opened new lines of research and forms of action inside ICMI, so that we may talk about a genuine ICMI Renaissance. In our contribution we examine the background and circumstances that fostered and shaped the emergence of the new issues that have developed in mathematics education up to the present day

The authors and theme E participants made these explorations because the study of curriculum reform is still in its infancy, and its foundations are in the early stages of being built. The papers should be read individually in order for the reader to make full use of their nuanced implications. However, several key considerations stand out across these chapters that we suggest should shape approaches to future curriculum reform and reform research efforts. Considering Curriculum Reform Contexts as Systems Can Make Important Choices Stand Out Curriculum reform is not carried out in the abstract but is always situated in a particular context at the jurisdiction level, and further instantiated within multiple local contexts like schools and training programmes. While these contexts are all unique,

In particular, the use of digital tools in mathematics education affects the meaning-making processes. This paper discusses meaning-making from a phenomenological standpoint, in which interpretative activities are relevant. This approach requires a careful analysis of the semiotic resources' evolution, including those related to the used digital tools. The paper aims to introduce an analytical tool, the Timeline. This tool is an elaboration on previous analysis tools, like the interaction flowchart and the semiotic bundle. Such a tool allows the analysis of relationship among interactions, semiotic resources, and meaningmaking. In this paper, the Timeline is used to analyze two episodes from two different learning experiments where GeoGebra and augmented reality are used. High school students from Italy and Israel participated in this study. Video recording has been used to document the entire learning experiments. The analysis provides evidence that the Timeline enables investigating the relationship between students-teacher-artifacts interactions and meaningmaking. Moreover, results may give teachers ideas for using digital tools to foster students' meaning-making.

We consider factors in curriculum implementation including physical materials, technologies, but also processes such as classroom and system assessment practices and, in a privileged way, the role of teachers. Curricular change can become just a proposal printed on an official paper if it does not actively involve teachers and their practices, and if it does not secure the needed resources for teachers. In focusing in this chapter on the implementation of curriculum reform,

In this paper, we analyse students' manipulation to explore and justify their geometrical reasoning on a free online touch device: the Geometric Constructer (GC) software. We discuss data from a teaching experiment with Italian High School students. The experiment was videotaped. Based on this we observe two domains (constructive and relational) regarding the development of geometrical thinking on GC. Students' manipulation on constructive domain is basically done to make construction and it contributes to exploration and to arise conjecturing. Indeed, manipulation in relational domain can suitably support and improve students' justifying and proving performances.

It explores the use of AiC (Abstraction in Context) as a tool for the analysis of the epistemic actions involved in these processes. It is reported a first analysis developed by the research team in order to be used as protocol-guide in the analysis of a study carried out with PhD students in Mathematics Degree in a Spanish and an Italian University, who face problem solving games. The case study shows the process of discovery that a PhD student makes to formulate a general recursive formula. It is a key for understanding the interaction between the AiC model and the characteristics of backward reasoning. The analysis allows to combine the two models-backward reasoning and AiC-in a unified framework that allows to focus both short-term and long-term processes in students' activities.

The years after WWII up to the late 1960s were crucial in this evolution for both the settlement of some institutional aspects, mainly concerning the relationship with mathematicians, and the establishment of new trends of the activities. In this paper we outline, on the basis of unpublished documents, the role of two important figures in those years: Heinrich Behnke and Hans Freudenthal.

In this chapter, we discuss data from two teaching experiments carried out with Brazilian and Italian high school students dealing with GeoGebraTouch (GT) and a Geometric Constructer (GC) software. With the focus on strategies used by students to solve the proposed tasks, we suggest two domains: Constructive and relational. Furthermore, we suggest the drag-approach as an important form of manipulation to improve geometrical thinking. Finally, we present a selected variety of representative examples of didactic, cognitive, and epistemological implications for learning and researching with the use of DGEwT.
