Row Call is a great Google Sheets add-on that creates a separate sheet based on Google Form responses.
Instructional Purpose Use one Google Form to collect students work, such as an Assignment Dropbox Template, and then have Row Call sort the responses instantaneous by submitter. While you can sort the main sheet by name in order to review responses, I like that this keeps it clean and organized by putting it on individual sheets.
Vocaroo is a simple to use audio recording tool that students can use to create simple podcasts. Once the recording is done students can share the podcast via a link, embed code, share on social media, download or via QR code.
Here are some instructional uses for Vocaroo:
students can record a summary of a book, create QR code and place around room or near library shelves
students can record themselves explaining a concept
students can read a paper they wrote
students can interview another person for a story
students can record a song/rap they wrote about a concept
There are plenty more examples, but this is just a few to get teachers and students started. Happy recording!
