Effective Practice Abstract/Summary
Abstract/Summary of Effective Practice: 

1. Audio feedback was perceived to be more effective than text-based feedback for conveying nuance; 2. Audio feedback was associated with feelings of increased involvement and enhanced learning community interactions; 3. Audio feedback was associated with increased retention of content; and 4. Audio feedback was associated with the perception that the instructor cared more about the student. Document analysis revealed that students were three times more likely to apply content for which audio commenting was provided in class projects than was the case for content for which text based commenting was provided. Audio commenting was also found to significantly increase the level at which students applied such content.

Description of the Effective Practice
Description of the Effective Practice: 

From spring 2004 through summer 2005, instructors at West Virginia University taught seven asynchronous online sections of Advanced Teaching Strategies, a course in the program of Curriculum and Instruction . Enrollment in these course sections consisted of master’s and doctoral level students Despite feedback that students were highly satisfied with interactions and learning experiences, the instructors wanted to do more to enhance relationships with students. In collaboration with a colleague from Virginia Polytechnic Institute and State University (Virginia Tech) they devised a study to determine if richer nuance could be conveyed by using audio feedback in an asynchronous learning network. In addition to text-based feedback, the instructors incorporated audio commenting. When posting audio comments to the discussion board, in emails to the entire class, or to small groups, the instructors produced wav files using Audacity freeware. The files were then added to the discussion board or email as attachments. -- In the case of individualized feedback, the instructors selected various Word document based submissions and discussion posts made by a student, converted them to PDF’s, and using Adobe Acrobat Professional, inserted audio comments which were sent back to students via course email. This type of individualized commenting was also used for the midterm case studies, final reflections and the group project. The instructors provided approximately half of the individualized feedback in a text-based format and the other half via audio. At the end of the course, all students had received six documents in which text feedback was used and five in which audio feedback was used. To avoid the introduction of bias, prior to the beginning of the semester each assignment was given a number from one to 12. These numbers were then entered into excel and randomized. From this list, instructors assigned alternating text-based or audio feedback as the modality that would be used.

Supporting Information for this Effective Practice
Evidence of Effectiveness: 

Several kinds of evidence--unsolicited feedback, end of course survey data, post course semi-structured individual interviews, and final project document analysis—showed gains in students’ ability to understand nuance, to feel increased involvement, to retain content, perceive instructor caring and apply course content at higher cognitive levels. Subsequent data collection from 17 courses supports the findings of the original study and discounts a novelty effect.

How does this practice relate to pillars?: 

In addition to gains in learning effectiveness and student satisfaction that accompany access to greater nuance through audio feedback, faculty found that giving audio feedback took less time, thus enhancing cost effectiveness. [The mean feedback volume for text feedback was 129.75 words (SD=57.43) and 331.39 (SD=89.31) for audio. The mean time required for the instructor to provide feedback, was 13.43 minutes (SD=4.53) for text-based feedback and 3.81 minutes (SD=0.76) for audio].

Other Comments: 

Comments from students: I just finished answering some questions about the time it took to listen to comments or read comments. My answer was that it took longer. However, I wanted to clarify that a little. It took longer because I replayed the comments a couple of times so I could really see what was being said as it related to my work and get more out of it. I don’t do this when the comments are written because I don’t think they are as good. It is very rewarding and helpful to HEAR your comments. Now I understand more about what you are trying to say than I did with the last set of feedback we got. Thanks! We’ve had written comments twice and verbal comments twice now. Let me guess – this is someone’s research project right? Let me just save you some time. The verbal feedback is much, much, much better than the written. I said the same thing when I talked to you on campus last month. So can you just send me the voice comments from here on out, say there is no comparison between the two at all and nix the written stuff? That’s probably not going to happen, but I thought it was worth a shot!
