International Journal of Didactic Mathematics in Distance Education

Aims & Scope

The International Journal of Didactic Mathematics in Distance Education (IJDMDE) is an international, peer-reviewed, open-access journal published biannually (April and October) by Universitas Terbuka (Open University), Indonesia. This institutional grounding gives IJDMDE a singular advantage: it is published from within a living laboratory of distance education at scale, directly informing the research it publishes. IJDMDE occupies a distinctive and underserved scholarly space. It is among the very few international journals dedicated exclusively to the intersection of didactic mathematics and distance, digital, and technology-mediated learning — interrogating not merely what mathematics is taught, but how mathematical knowledge is designed, mediated, and reconstructed when teacher and learner are separated by distance, whether physical, temporal, or technological. This dual focus sets IJDMDE apart from general mathematics education journals and from general educational technology journals: it is the scholarly home for researchers who work precisely at this boundary. The journal publishes original empirical, theoretical, design-based, and methodological research. It draws from a wide range of design-oriented theoretical frameworks — including the Theory of Didactical Situations (TDS), the Anthropological Theory of the Didactic (ATD), Didactical Design Research (DDR), Realistic Mathematics Education (RME), sociocultural theory, and variation theory — evaluated by their capacity to illuminate and improve mathematical learning in distance and digital contexts. IJDMDE does not privilege any single framework; it privileges rigor, relevance, and didactical operationalizability.
