Class discussions based on videos and PowerPoint presentations can be easily implemented using the website VoiceThread (free subscription).
VoiceThread is a collaborative, multimedia slide show that allows people to navigate slides and post comments. It is an ideal tool to deliver the content of your hybrid or online classroom asynchronously. The main features of VoiceThread are the following:
(1) in VoiceThread, you can not only record voice over videos, images, files, and PowerPoint slides, but also make notes and highlight specific points, all of which will be recorded as a video that students can watch online;
(2) in VoiceThread, each student in your class will be able to stop the slide show at any point and post comments in 5 ways – using voice (with a mic or telephone), text, audio file, or video (via a webcam). By using this feature, your lecture (i.e., the slide show you created in VoiceThread) will be permeated with students’ thoughts and discussions throughout the presentation, creating a very dynamic asynchronous classroom environment.
To learn more about VoiceThread go to voicethread.com. In the website you can find very helpful tutorials such as this short, 2 minutes video – https://voicethread.com/share/8381/.
