This research study compares the use of two different online asynchronous discussion technologies in hybrid algebra classes at an urban community college. One of the technologies is the discussion board, which utilizes text commenting, and the other technology is VoiceThread, which allows users to interact with audiovisual commenting. Students posted solutions to problems using one of these discussion technologies to create collaborative pre- and post-exam reviews. The impact of different methods of communication on student participation, exam scores, and satisfaction was analyzed. Participation rates and exam scores did not differ significantly with the use of the two different discussion tools. Surveys administered at the end of the semester showed that students preferred using a text-based discussion environment. Students' level of agreement to questions about ease of using the mentioned technology, its aid in teaching them the material, and their willingness to use it again were significantly higher at the 0.05 level in the text discussion group (n = 48) than in the audiovisual discussion group (n = 39). Advantages and disadvantages of using both technologies are discussed, and recommendations for improvement are shared.
