Last Friday, I had our first group of students present on their personal learning network. I used this rubric to evaluate their presentation as well as had the class access the student blog he/she was referencing to leave real time comments about the presentation (we pulled up the blog and had it appear via our overhead projectors). While the student was speaking, the class reacted to the presentation. The instantaneous feedback the students provided was valuable to the presenter. If a classmate did not feel comfortable offering oral feedback in our class debriefing, the evaluator could reference his/her blog and see what reactions the class had to the presentation.She then goes on to provide some examples of the feedback from the students – you should check it out.
In a subsequent post, she also links to the audio of some of the students' presentations (recorded with an iPod and an XtremeMac MicroMemo). These were their first attempts at this, so please only offer constructive criticism.
Update: Jessie Comp just posted about her experiences as well.
