I would start with making a complete syllabus for the course (the contract style type). This would include all the detailed information about the course, all required information from the college, key dates, and a breakdown of the grading scheme. This document will be fit for accessibility and will be clear and easy to read.
I will then take out the key information and form it into a graphic syllabus. I will be using Canva to design the graphic syllabus and making it printer page size 8.5×11 inches so it can be printed if the students want to refer to a printed copy. I want to include key information that I would find helpful as a student. This would include: a visual breakdown of grades, instructor contact information, helpful resources, what the students need to do each week for the class, and a timeline of key dates. To ensure accessibility, I would make sure to have clear colors and fonts and have it accessible through the Canvas page. In addition, I would make sure that all information is thoroughly covered in the traditional syllabus and therefore this is only a supplemental page if they need it.
