So, how does one learn to teach something one was never taught?
Here are the tools!
(Please note that Canon Press is the publisher for some and Logos School publishes some supplemental items. It's OK. They're friendly with one another. :) )
As mentioned before, we reviewed Introductory Logic a while back. The best practice I found is to finish the whole book before beginning to teach the first lesson. Even with the answer key, one needs to know this subject well to come up with classroom examples and correctly approve creative student answers.
I particularly appreciated the Logos Test booklet, as I had limited time to come up with my own exams. It served us well.
I took a multiple-point approach to use of the accompanying Logos DVD for Introductory Logic. I watched it myself to know how to teach better, I loaned it to parents taking the class with their young people to help them reinforce the lesson, and I showed some segments to the class to review, amplify, and clarify my previous instruction.
Some time soon, we will be ready for the next step!
First, students are introduced to propositional logic, logical operators, and truth tables, while reviewing and reapplying the concepts of validity, contradiction, consistency, and equivalence. Next they learn to construct formal proofs of validity by using basic rules to derive an argument’s conclusions from its premises. Finally, students discover how they can use the technique of “truth trees” to determine consistency, self-contradiction, tautology, equivalence, and validity.
This text, together with Introductory Logic by James Nance and Douglas Wilson, provides students with a rigorous course in logic that will help them excel in every other subject they will study, from math and science to rhetoric and the humanities. Extensively revised and updated, with additional review questions and exercises for each unit, this book is an essential part of every Christian school or home school curriculum. 27 lessons; consumable.
James B. Nance has taught at Logos School since 1990, where he currently teaches logic, rhetoric, calculus, physics, and Christian doctrine. He is also the co-author (with Douglas Wilson) of Introductory Logic for Christian and Home Schools. James and his wife Giselle have four children. (publisher's website)
Changes in the New Edition
Expanded, Corrected, Completely Redesigned Second Edition
Our popular Logic curriculum has been changed in a number of critical areas:
First, in order to present to the student a more logical progression of topics, the section on defining terms has been moved from Intermediate Logic to Introductory Logic, where it is taught along with other branches of informal logic and categorical logic.
Second, review questions and review exercises have been added to each unit for every lesson in the text, effectively doubling the number of exercises for students to verify their knowledge and develop their understanding of the material. Additionally, some especially challenging problems have been included in the review exercises.
Third, the definitions of important terms, key points made, and caution signs regarding common errors are now set apart in the margins of the text. This should help students to distinguish the most important topics, as well as aid in their review of the material.
Fourth, every lesson has been reviewed in great detail with the goal of improving the clarity of the explanations and correcting several minor errors that were found in the original edition.
Fifth, the book is now in a handsome perfect-binding, with all exercise pages perforated for easy removal. (publisher's website)
Answers appear to be more cut and dried for Intermediate Logic, when one consults the essential Answer Key. Know the terminology frontwards and backwards so that it is second-nature before you begin to teach.
How is that done? Watch James Nance on the companion Logos DVD. This set appears to have been recorded/released at the same time as the other set mentioned above.
Nance coauthored Intermediate Logic with Doug Wilson. He is the sole author of the Intermediate Logic book.
Watch the DVD. Understand what is presented in the text. Then, proceed to the next. (You may know some of the symbols from set theory in mathematics.) Then, prepare your own "lecture notes" and put the concepts of logic in your own words. Experiment with your own illustrations. Perhaps you could try them out on another logician (even via email) before teaching/inflicting them on your first class.
And then what? Take the tests. It's only fair, right? Right? Refrain from looking at the answer key. Perhaps you could do what we did. After the first 30 minutes of testing, allow yourself notes. Notate the answers you write or change with an "N" in the margin. Then, for the last 15 minutes, consider it open book, noting new answers or changes with a big "B." This helps testing meet its evaluative purpose, begin the correction process, and also help the test-taker learn earlier from mistakes or deficiencies.
