Developing competencies in language and communication is becoming increasingly important for the contemporary engineering student if career success and community engagement are to be enhanced. The integration of language, and other ‘soft-skills’, into broader engineering education could assist in preparing students to become more employable and improve their overall engineering ability. This study adopted a design-based research strategy to develop design principles regarding the integration of language and communication skills into engineering education. Eleven participants were purposefully sampled to form part of a design team that became responsible for this development. The principles that emerged emphasised the role culture plays in the process of learning, highlighting the importance of embracing cultural diversity in ways that frame it as a strength to be exploited. Differing abilities and levels of English language proficiency need to be accommodated, requiring lecturers to build in a feedback process to manage progress and effective student engagement. It is advisable to adopt a holistic approach to teaching and learning, and to pay careful attention to appropriate learning strategies. An integrated learning environment necessitates the dismantling of the traditional silos that have characterised engineering education and greater cooperation among various disciplines needs to be encouraged.Transdisciplinary contribution: The integration of language and communication into engineering education goes beyond the boundaries of individual disciplines and involves collaboration between the faculties of engineering and humanities as well as industry partners, and accreditation bodies. The diverse range of expertise required, range from linguistics and pedagogy to engineering and instructional design.
