Authenticity ahead of interdisciplinarity – a scoping review of student experiences in interdisciplinary science projects

Abstract

Interdisciplinary projects are reported to facilitate the development of both disciplinary and generic skills. They vary in their design and implementation, but the effectiveness of different project models has not been studied. The aim of this study was to determine student satisfaction, engagement with learning and development of employability skills across interdisciplinary projects with different delivery models. This scoping review appraises interdisciplinary projects implemented in science-based undergraduate degree programs. Projects with varying models of delivery, interdisciplinarity, authenticity and external partner involvement were examined, and the reported student learning and satisfaction ratings compared. Descriptive statistics and cross tabulation using Fisher’s Exact test were used to analyse the data. The interdisciplinary project model had little effect on engagement with learning, but student satisfaction improved if the project task was rated as authentic (p<0.05). Improved learning was reported in about half of the projects reviewed. Improved employability was reported in projects where students used discipline-based skills to provide a consultancy (p<0.05), and those where an external partner was involved (p<0.05). The interdisciplinary project model did not affect disciplinary or employability skill development, apart from interdisciplinary competence, which was significantly improved in a truly interdisciplinary project (p<0.01). Interpersonal skill development was significantly improved where projects had integrated rather than sequential tasks (p<0.05). Overall, interdisciplinary projects that were authentic and/or involved an external partner generated better student satisfaction and real-world experience. These results inform the future design of interdisciplinary project-based learning tasks and encourage involvement of external partners in project design and delivery.
