Doug Ragan has been working with the Alchemie team -- founded by a former chemistry teacher, Julia Winter -- for a number of years. They have been working over the last year on a new project, named Kasi, which delivers sound-based feedback to students as they learn with tactile pieces on a magnetic whiteboard. The goal is to build an accessible learning system that helps ALL students learn, and is particularly important for those with visual impairments.
As many teachers are preparing to teach online, we are revisiting posts from the ChemEd X archives like this one that might be of help. The author has updated this activity by adding notes specifically to help those teaching remotely. This post about Classkick was originally published April 22, 2016. The platform is now all web based and Doug has compiled a list of public assignments that you are free to modify for your own use.
