Exploring how response technologies shape instructor feedback: A comparison of Canvas Speedgrader, Google Docs, and Turnitin GradeMark

Abstract

There have been few studies examining the variation that exists within modes of feedback: for example, comparing how electronic text feedback created using Google Docs differs from electronic text feedback created using Microsoft Word or how audiovisual feedback created using TechSmith Capture differs from audiovisual feedback created using Screencast-O-Matic. However, the programs that instructors use to create feedback have different affordances, meaning that even within a single mode, the feedback students receive on their writing can vary significantly. To better understand the variation that exists within a single mode, this study investigates how affordances of Canvas Speedgrader, Google Docs, and Turnitin GradeMark impacted electronic text feedback.Based on analysis of 131 feedback files created using the 3 programs, in conjunction with 5 student surveys, and 2 instructor interviews, the study provides insights into how instructor written commentary (location, form, type, focus, and mitigation) varied by program and how participants perceived of feedback provided through the 3 programs. The study...s primary finding is that the affordances of the programs used to create electronic text feedbackresulted in significant differences ininstructorcommentary and instructor and student perceptions of feedback.
