Making it work: Practical work in tertiary Life Sciences

Marina Constantinou; Nikolaos Fotou

Abstract

Practical work has been regarded for long and, as argued in this paper, unquestionably a fundamental component in the teaching and learning of biology-related sciences across all educational levels and an integral component of most, if not all, degree programmes in the Life Sciences (LS) in Higher Education institutions around the world. Whilst there are claims attributing educational benefits to practical work for LS undergraduates as per its effectiveness in promoting the development of conceptual understanding and practical skills [2, 3], these sometimes are either not empirically tested, or, for many reasons, seem overly ambitious. This almost a priori and unquestionable effectiveness of practical work - to that extent that its devoid in LS degrees is virtually unimaginable [4] - points to the need for a more evidence-based approach on its role in supporting undergraduates’ learning and thus its necessity in LS undergraduate curriculum. This need is more critical especially when practical work instruction is very expensive, both for academic personnel, laboratory equipment, reagents and supplies during an academic year. This paper reports on findings of a mixed-methods case study conducted with LS undergraduate students in the UK to examine the effectiveness of practical work in conceptual understanding and development of practical skills. Observations and in situ informal assessment of undergraduates’ conceptual understanding and skill development provided an objective empirical evaluation of the circumstances under which practical work is effective in these two areas. The preliminary findings of the study reported here showed that whilst the development of basic practical skills is satisfactory, conceptual understanding is, in most cases, lacking or insufficient. Deriving recommendations on how such an effective practical work lesson should be designed, staged and conducted are also reported.
