Flipping the laboratory: improving student engagement and learning outcomes in second year science courses

The flipped classroom pedagogy was implemented in two core undergraduate science courses; Animal and Plant Biochemistry II (APB) and Microbiology and Invertebrate Biology II (MIB) to encourage students to prepare for laboratory classes. Students often attend class without little understanding or appreciation of what they are going to learn in the laboratory, the types of techniques they are going to use or the safety precautions required. This is not only hazardous for students but also requires detailed explanations from teaching staff at the start of class, overloading students with information. This disconnection between theory and practice was overcome by 'flipping the laboratory' to integrate online, interactive pre-laboratory activities into the curriculum. The aims of this study were to: (1) evaluate student engagement with pre-laboratory content; (2) investigate student performance and learning outcomes; (3) review failure rates following implementation of pre-laboratory activities. Students agreed that the pre-laboratory activities bridged the gap between theory and practice (65%) and enhanced their engagement with course material (79%). The integration of pre-laboratory activities significantly increased student learning outcomes immediately after implementation into the curriculum, despite a 26.8% increase in enrolments from 2011 to 2017. Failure rates significantly decreased in both APB and MIB over three consecutive years.
