Aligning Perceptions of Laboratory Demonstrators’ Responsibilities To Inform the Design of a Laboratory Teacher Development Program

Abstract

Throughout countries such as Ireland, the U.K., and Australia, graduate students who fulfill teaching roles in the undergraduate laboratory are often referred to as “laboratory demonstrators”. The laboratory demonstrator (LD) model of graduate teaching is similar to the more commonly known graduate teaching assistant (GTA) model that is prevalent in the United States. While the responsibilities of LDs and GTAs in the undergraduate laboratory are similar, both cohorts experience different recruitment and training processes that can influence their teaching behaviors. With respect to enhancing the teaching capability of GTAs, considerable research has investigated the design, implementation, and evaluation of various GTA teacher development programs as well as identified various factors that influence their teaching behaviors. However, there has been relatively less research devoted to enhancing the teaching capability of LDs. This research study set out to inform the design of a teacher development program...
