My son took this course for homeschooling this year. He was just 13yo when he started it. He said the DVDs were very helpful. (I don't have them and will purchase them for my next child. He saw them online with a self-paced course offered free because of COVID promotions through Memoria Press.) I wanted to learn with him. I think doing the daily exercises would have helped me immensely in my understanding. I had to re-read chapters to gain any elementary understanding, since the ideas are so new to me. I can see, though, even from my rudimentary grasp of the subject, how invaluable logic is as a subject to arrange one's thinking in an orderly way and give a person categories for thought--what ideas are contradictory, etc. I'll try to give a more thorough review on my blog sometime and link it back to here, as to why we chose this text over some of the others in the classical curriculum world. This was exactly what we wanted for logic. The only negative I'd offer is that the teaching style is very traditional (translate: boring) and doesn't inspire much "wonder." It is very nuts and bolts, which is fine for the subject of logic, I guess! The two subjects I've used with MP for which I've seen the teachers on DVD have been thorough and well-organized, but the teachers have been dry. ABeka's teachers are much more lively (but of course, they don't teach logic or Latin, which is what I used MP for.)
2022: I read this with my second son while teaching him. Have the DVDs now, but he actually doesn’t like watching them and prefers just reading. He got a little confused on the chapter about obversion and contraposition, but so do I. :) My comprehension was MUCH faster this second time around!
