Joanne Brownlee, Nola Purdie, and Gillian Boulton-Lewis (2010) describe an interesting method to increase student’s epistemological beliefs using reflective journal assignments. Brownlee and colleagues found that when students engaged in these reflective practices, they had significantly improved their epistemological beliefs over that of students who did not complete these activities.
