My Take
It is a wonderful teaching tool because it allows students to post what they feel and it gives me piece of mind knowing that what they post is for the class only. Signing into your class can be a little difficult sometimes if you have not set up a permanent link or bookmark to it directly. But overall a big thumbs up!
How I Use It
Kidblog is a great place for teachers have have online discussion in a safe space. I often use this in my Character Education lessons. It is easy to pose a question and have students respond.
