For such a useful study, logic can be a bit intimidating. This pair of workshops by two homeschool graduates goes a long way toward making the topic more understandable. A single DVD covers both Part I - Learning to Think Logically and Part II - Using Your Thinking Toolbox. The DVD also includes PDF files for the workshop handouts. Originally given to a roomful of students, Hans and Nathaniel Bluedorn together present both workshops (each about 50 minutes). With a wry touch of humor and some audience interaction they examine several different types of fallacies in Part I and ways to strengthen and train yourself to think logically in Part II. Watching a workshop video is never the same as being there in person; perhaps the biggest loss is the absence of the illustrative cartoons that were obviously a part of the original workshop. Dilbert, Calvin & Hobbes, and Far Side do not allow their cartoons to be used in video presentations and I found myself regretting that fact. Still, if you’re wanting an introduction to the whole subject of logic, this is a good way to start.
