It can be a worthwhile exercise to put some time and consideration into how information will flow across the platforms and devices that students might be accessing for your college or university course. It will be essentially impossible to expect all students to have the same conditions (hardware, notification setups, etc.) but it is possible to describe the primary information flow as designed so that students can adjust as best as possible.
Step 1: Identify the platforms used for Course Content, Text-Based Dialogue, and Video/Voice dialogue
Step 2: Consider the types of information and experiences used in each of those platforms
Step 3: Define the designed modes of accessing and contributing to each of those platforms for students
Step 4: Acknowledge all of the additional possible layers and interconnections between those modes and systems.
