The Elevate Team have purchased a text wall service (www.polleverywhere.com) for those who would like to pilot the use of free text interaction in the classroom. The service will allow you to gather student free text response via them texting, completing an online form or using Twitter.
We used it to gather audience thoughts during a JISC RSC Eastern VLE Forum meeting which we hosted at UCS.
This technology has offers significant potential to allow you to design more active learning activities within your classroom teaching, and complements the increasing interest in clicker technology. So, why don't you come and talk to the Elevate Team to discuss the opportunity to use this technology in your teaching.
