Voice Thread

VoiceThread is a tool where class discussions can be created online. It is a multimedia slide show that holds images, documents, and videos and allows groups of people to navigate pages and leave comments in 5 ways - using voice, text, audio file, or video.
It is similar to Jing in many ways as it allows you to draw on images whilst commenting however unlike Jing you do not have to download VoiceThread. VoiceThread is free to use and is one of the fastest tool I have come across after using a range of technologies.
Unfortunately when using VoiceThread only a maximum of 3 voice threads can be stored at the one time.
It is extremely relevant to the classroom as teachers can use it to communicate with individual students or the whole class, it allows students to create a personal portfolio, develop their English skills and as a tool for project work and assessment.

With so many options and avenues it is a very practical tool to employ in the classroom! I would use it!
