I found the presentations all informative and it was really interesting to see the various opinions expressed in each group. For instance, in the presentation about the internet (Good, Bad, and Ugly) there were dissenting opinions on Wikipedia. One person said they would shy away from using it, while another said that it can be useful when used in conjunction with other sources. I tend to agree with the latter opinion. I've used Wikipedia as a quick reference guide or to point me in the right direction for more reliable sources of information. I think it can be a valuable resource in the classroom as long as students don't rely solely on the information found there.
I was really impressed with the cyberbullying video as well. It was funny, but highlighted some very important points about bullying in general. The BYOD presentation was very well researched and they used a lot of visuals. The Internet Filtering presentation brought on an interesting online discussion about what, if anything, should be blocked. I know I found it frustrating that YouTube videos were blocked in my first placement!
I encourage you to explore the various presentations (most of them linked) and consider your own opinions on these topics.
