That Journal has a History: Overview of the Technological Tools and Theories Studied in the International Journal for Technology in Mathematics Education, 2004-2018

This paper constructs an overview of the historical development of the International Journal for Technology in Mathematics Education (IJTME) during the period 2004-2018. The titles of the published papers in this period are examined, focusing on what technological tools were studied, and what theoretical ideas were used to study the teaching and learning of mathematics with technology. This analysis shows the ways in which the IJTME has particularly focused on how students use, or can be helped to use, technological tools (mainly CAS, dynamic geometry software and calculators), as opposed to other possible topics such as historical analysis, policy, or international comparisons in the teaching and learning of mathematics with technology. The areas of mathematics primarily addressed by the articles are algebra and geometry, informed by the development of certain theoretical ideas (from instrumentation theory to activity theory for example) over the last 15 years. While the journal should keep investigating this area of research, it is also essential to extend the journal's scope to wider perspectives including sustainability of historical developments of technological tools, book review, systematic literature review, dialogues between our community members through commentaries on the published papers, and so on.
