Improving the Effectiveness and Efficiency of Teaching Large Classes: Development and Evaluation of a Novel e-Resource in Cancer Biology

Date Received:10/08/06 Date Accepted:15/01/07 This paper describes the development and evaluation of a blended learning resource in the biosciences, created by combining online learning with formal face-face lectures and supported by formative assessments. In order to improve the effectiveness and efficiency of teaching large classes with mixed student cohorts, teaching was delivered through a variety of media which included three main components; (1) an interactive online tutorial, based on the cellular processes of DNA replication, damage and repair in relation to oncogenesis (2) formative assessment in the form of multiple choice questions to allow self evaluation and (3) small group follow-up workshops, to encourage deeper learning. The online tutorial was designed using Flash © software to help conceptualise complex cellular processes in time and space. It was supported by formative quizzes, references and printer-ready notes. Introduction of these resources in 2005 led to significant improvements in summative assessments across all student cohorts compared t
