Well done. The lesson plan is informative, and clear. The student learning objectives, and the related standards provide opportunities for learners to engage with content.
I also commend you for your use of the blog post to share and connect with other learners online.
I do have questions about the evaluation, and more importantly the synthesis involved in the use of tools like Diigo. I'm interested in how we provide opportunities for students to "press pause" on learning as they connect and curate online information. Nothing to address right now...you just provoked some thinking on my part. :)
Good work. Badge awarded.
