Professional bodies expect engineers to show competence in both mathematics and engineering topics such as mechanics, using their abilities in both of these to solve problems. Yet within engineering programmes there is a phenomenon known as ‘The Mathematics Problem’, with students not demonstrating understanding of the subject. This paper will suggest that students are constructing different concept images in engineering and mathematics, based on their perception of either the use or exchange-value for the topics. Using a mixed methods approach, the paper compares 10 different types of concept image constructed by students, which suggests that familiar procedural images are preferred in mathematics. In contrast strategic and conceptual images develop for mechanics throughout the years of the programme, implying that different forms of competence are being constructed by students between the two subjects. The paper argues that this difference is attributed to the perceived use-value of mechanics in the career of the engineer, compared to the exchange-value associated with mathematics. Questions are raised about the relevance of current definitions of competence given that some routine mathematical operations previously performed by engineers are now being replaced by technology, in the new world of work.

In this paper we discuss perceptions of the benefits of learner-generated podcasts for supporting postgraduate engineering students in a mathematics-intensive course. The course under study had previously been highlighted as one in which students had struggled to attain knowledge that formed an essential underpinning to their degree programme. Podcasts were used as a means of concretising abstract mathematical knowledge so that students could access and share such concepts in a meaningful way. The experiences of three students (in a single cohort) were examined qualitatively at every stage of the exercise: introduction, pre-test, podcast creation, podcast peer evaluation, post-test, and focus-group session. The data suggest that this specific technique led to improvements in mathematical learning through the analysis of podcasts rather than through the creation of them. [ABSTRACT FROM PUBLISHER]
