A formative computer-based assessment (CBA) was one of three instruments used for assessment in a Bachelor of Education course at Queen's University (Ontario, Canada) with an enrolment of approximately 700 students. The formative framework fostered a self-regulated learning environment whereby feedback on the CBA was used to support rather than measure student learning. The four types of feedback embedded in the CBA included: (a) directing students to a resource, (b) rephrasing a question, (c) providing additional information and (d) providing the correct answer. Although students originally reported positive experiences with the formative CBA, two follow-up surveys revealed that they found the four types of feedback to be moderately effective in supporting their learning.
