Low-bandwidth options for online education (grad school only)

Nobody knows when this pandemic will end really. 2 months, 3 months, 1 year. Should we stop our lives and just wait for things to get back to the way they used to be? Or should we transform now and evolve according to the call of the times?

I'd like to talk about creative ways to deliver learning without being bogged down by accessibility issues. Given the internet issues prevalent in the Philippines, I suggest we focus on programs that require only the lowest bandwidth from students. For example:

• Facebook-based classes
• Courses that can be accessible by txt (to be clear, am not referring to SMS here)
• Courses that can be viewed offline
• Instructional materials that are self paced

Educators can avoid streaming or Zoom-based classes if that's an issue. And students can do their work at any time they want. 

The above suggestions address the issue of accessibility, which has been put forward as one of the main arguments for ending the semester and mass promoting everyone. IMHO, if accessibility is an issue, data does not support it. If you check the link below:

Internet users in the Philippines spend an average of 9 hours and 45 minutes per day online - even during a pandemic.

I see that people are spending more time now playing Mobile Legends or making Tiktok videos

If we have time for these things, why not dedicate some time each day too for education?

I teach grad school students. The suggestion of continuing classes may only work for them. The situation could be different for elementary, high school, or college students. I’m open for discussions.
