This survey on interdisciplinary aspects of the teaching and learning of mathematical modelling focuses on the period 2012–2021. Based on our review of research literature published during this time, following the brief we were given to conduct the survey, we identified four major threads of contributions as these relate to schooling. These threads were: the importance of a well-understood relation between mathematics and the real world supporting interdisciplinary work in mathematics education; the contribution to knowledge about modelling of interdisciplinary research and teaching teams; issues and challenges in the relationships among mathematical modelling, mathematics, the real world and interdisciplinarity; and, mathematical modelling providing critical high leverage to ensure mathematical depth in STEM integration. Each thread is exemplified with relevant research. Future directions are offered in our final reflections.
