Two recommendations for success, if the students are absolute newbies to using computers:

1. Have a senior citizen student to teacher ratio of no more than 2 students per teacher, assistant, or computer coach.
2. Require students to enroll in a short, pre-course device workshop. One of the most important, often overlooked details is to make sure that each student can see and comfortably read information on their device screen. Make sure that each student’s device can access the Internet from your class location. Help students to understand that teachers and coaches do not stop class in order to find device passwords, load required software, or to fix device hardware.

My personal preference is to teach a class of 8 to 10 newbie senior citizens with a couple of computer coach assistants on standalone computers or on bigger screen devices all from the same computer company.
