Peer feedback can be a tool to help higher education students develop presentation skills. This process can be supported by using online tools that enable peers to provide feedback annotated to specific moments in the presentation. The current paper investigated whether providing and receiving peer feedback using an online tool was related to improvement in students' presentation skills, whether students provided different peer feedback in comments and annotations, and whether student characteristics played a role in students' presentation skill improvement. Results from 56 second-year undergraduate Education and Child Studies students indicate that providing and receiving feedback did not relate to students' improvement in presentation skill, and that high ability students showed less improvement in presentation skills than medium and low ability students did.
