Create your rubric as a PDF (e.g. how many points for content, voice inflection, not saying "um", "like", and "and yea"). Here is an example that you are free to use. Import the PDF into Squid, one per student. As the student gives their presentation or as you review their work, fill in the rubric and make notes. Export the page as a PDF and send it to your student as feedback through Google Drive, Google Classroom, or email.
