The conceptual nuances of technology-supported learning in engineering.

Enabling theory-practice bridging in engineering education is essential for developing twenty-first century graduate capabilities. Massification, resource constraints, and technological development have resulted in significant shifts to alternative forms of practical engagement, such as the use of online laboratories, but how do these contribute to learning? Based on three illustrative case studies at a research-intensive institution in the Global South, this paper offers a conceptualisation of the degrees of complexity entailed in multimodal approaches to teaching Fluid Mechanics, Finite Element Analysis and Control Systems at different stages of their respective programmes The paper examines the different levels of abstract-concrete learning when students engage with verbal, symbolic, graphic and physical representational artefacts designed to enable cumulative learning. The conceptual instruments are theoretically and methodologically drawn from Legitimation Code Theory dimensions, which lend themselves to the graphic analysis of knowledge practices. It is suggested that the explicit integration of and shifting between levels of abstraction and complexity with different kinds of technologies enables the kind of cumulative learning necessary to prepare technically-equipped graduates for complex twenty-first century engineering contexts.
