Assessment feedback is an essential way to promote student learning. Students and teachers may benefit from educational technologies during the feedback process. The purpose of this study was to identify the feedback dimensions that were fulfilled by iPad applications (apps) and to compare teacher practice to the affordances of apps. Typological data analysis was used to perform this qualitative case study. We analyzed seven apps ("QR Code Reader, Schoology, Kahoot!, Nearpod, Socrative, ZipGrade," and "The Physics Classroom") that a high school physics teacher used to provide feedback in a technology-enhanced classroom. Data sources included classroom video recordings and the websites of these apps. To facilitate the analysis of the data, we enhanced the feedback dimensions identified by Hatzipanagos and Warburton (2009). Our analysis highlighted the diverse capabilities of these apps with regard to supporting the following dimensions of effective feedback: dialogue, visibility, appropriateness, community, power, learning, timeliness, clearness, complexity, reflection, and action. We found that through additional discussion and interactions with students, the teacher could support dimensions that an app did not support. This study not only underscores the critical interplay between technological tools and teacher practices with regard to crafting effective feedback mechanisms but also offers practical recommendations for educators seeking to optimize technology-enhanced feedback in classroom settings. Future research is encouraged to explore the technology implementation experiences of less experienced teachers. Examining teachers working at various school levels and from various countries can offer valuable insights.
