I had looked at TeacherTube.com many months ago. The premise of TeacherTube.com is that teachers and students will put up educational videos other educators and their students When I went to it recently, I found that it has not grown up very much.
When I searched for paragraph writing, I found 0 entries. When I used “essay writing, I found 9 entries of which 7 were commercial. When I widened the search to “writing”, I found 9 entries that actually dealt with the writing process (5 of them were commercial).
On the other hand, when I searched in YouTube.com for “paragraph writing”, I found 5 entries. When I searched for essay writing of the reported 300, about 50 actual deal with real writing (not making fun of it). I tried using “essay writing” -funny as a search term to get rid of some of the non-instructional ones. The search for writing revealed about 5,500 entries; I did not have the time to count those that actually were instructional.
I had great hopes for TeacherTube but they have not come true.
