Classical & Contemporary Best Practices in Learning for Parents & Teachers


Welcome to the 21st Century Lyceum!

Named after the ancient Athens property on which Aristotle taught after returning home from Macedonia where he tutored the young Alexander (the Great. Yes, that Alexander…), this blog is about teaching and learning best practices of the past 2400 years. With a target audience that originally consisted of primarily young, in-service teachers, its mission is now to serve as a resource mainly for parents who find the current pandemic-governed schooling environment a bit daunting.

The first season (roughly mid-2020 till early 2021) is dedicated to the identification and mitigation of logical fallacies and other tools of informal logic, understanding the learning preferences of both teachers and students, and bits and pieces of other stuff that crosses John Devos’ mind. Sprinkled in are interviews with homeschooling parents, current and retired teachers, and educational experts, all of whom can shed light on what a parent can do during a virus outbreak to make sure his or her children have the best learning environment possible.

While the blog is loosely set up to be experienced from beginning to end, those looking for introductory information on Bernice McCarthy’s 4MAT system of using learner preferences should check out episodes 3 through 8. Most other episodes deal in some way with informal logic theory and skill development.

Please use the Contact page to email John or leave a Comment to participate in the blog with a wider audience. 21CL also has a Boardhost forum that we hope becomes a much-used feature. All the posts since the blog began are listed in their entirety in reverse chronological order on the Blog page. For now,…

…here are the latest few posts on the Lyceum:


S1, E9: A Quickie on TRUTH

Identifying and dealing effectively with logical fallacies is only one part of informal logic. Informal logic is the kind we use during everyday discussions and information-gathering. The other part of this discipline is truth-knowing. 

Knowing the truth has become a huge issue in today’s climate of ubiquitous social media on which everyone’s opinion gets airtime, seemingly unlimited media outlets for information dissemination, and the overwhelming role that technology plays in all of it. So, let’s spend a short, video-less episode pointing ourselves in the right direction.

One of my favorite posters on Quora is Peter Kruger, an attorney in Wisconsin, who is a seeming polymath with some experience in astrophysics, woodworking, welding, and teaching English. His posts are always well-crafted and informative, so I wasn’t surprised when I came across a fantastic – if not also rather lengthy – delve into truth-finding by Mr. Kruger. The post functions as a sort of primer on vetting sources and is absolutely the best writing on the subject I have seen lately. He does use some profanity and his politics have a decidedly moderate-liberal slant, but read around all that, if you want, and you will have learned a great deal about identifying credible information sources.

The essence of his post is this list of questions you should consider about any information source:

  • Do I want to believe the source? Do I have a confirmation bias?
  • Is it a primary, secondary, or tertiary source? Or a combination? Why does it matter?
  • What actual, verified FACTS (not opinions) does it contain?
  • What inferences can reasonably be drawn from the facts, and do you have all of the facts to draw accurate inferences?
  • What is the authorial bias? (Kruger’s treatment of this subject is outstanding!)
  • What degree of institutional integrity does this source have?

Just listing these questions does not do his work justice, so I have reproduced his post here on this blog, verbatim. I hope he does not mind. I don’t think he will, since the whole thing is out there on Quora, anyway. If I get any kind of cease-and-desist request, I will immediately comply. So you’d better go read it now, if you are so inclined.

A great exercise Mr. Kruger included in his post is this terrific infographic / cartoon strip from The It is WELL worth your ten or fifteen minutes to watch it. No kidding. Viewing this graphic will be the best time you spend in the understanding of finding the truth.

Again, a quick reminder that this whole blog is designed to help you assimilate knowledge and skills that you can subsequently impart to the kids in your life. So, the overarching question is, “Can you imagine ways in which the information in this episode can be translated and transferred to said young ones?”
