A.J. Juliani shared his post 5 Projects You Can Do in the First Month of School
in which he outlines a number of ideas for things that students can do to show what they know. What I really like about the post is that he suggested providing students choice in how they would present their learning. He also provides choice in what topics students would explore with many of the choices he provides being real world topics that students are likely to have some connection to.
These projects aren't necessarily technology projects, however there is the potential for technology connection with many of these. Another part that I really appreciate is to share student learning with the world. While we should always be cognizant of protecting student privacy, we can share out samples of student work that doesn't identify the individual students. If you have questions about appropriate sharing, please let me know and we can discuss this further.
