Ms. Johnson's AP Biology Today: Cellular Structure and Function
Ms. Johnson teaches face to face Biology classes during the day.
In the evenings, she works on her asynchronous virtual course from home. She holds office hours a few nights a week and makes sure to personally contact students from time to time.
From: Student Dear Ms. Johnson, Help me!
The students in Ms. Johnson's asynchronous virtual course complete the work according to their schedule, whenever and wherever works for them. For example, some students attend face to face class during the day and do their online classwork in the evening.
I'm so glad you both had time to come today to get some extra help!
Ms. Johnson's After School Office Hours for Online Students
Other students might work on their assignments at the library or Starbucks on the weekends. Each individual gets to decide what works best for them. Ms. Johnson communicates her "live" availability so students know when to find her online.
Ms. Johnson also checks her email often, just in case a student runs into a problem and needs help outside of her office hours.
Teaching an asynchronous online class takes some extra work, since you have to be responsive as much as possible whenever the students choose to work. But, it also offers the possibility for flexibility for both the student and teacher, since they can work together to find time that's convenient for both.
