xpost: Is it worth it to do both Intro/Interm Logic AND Traditional Logic I/II?

[Kathie in VA]

I know most folks are trying to decide which to use for formal logic but I've also seen some go through both sets of texts. I know their approaches are a bit different but do they also cover different skills? Is there really a benefit to doing both sets of texts (other then more practice)?

We have used all of them except Traditional I. My son felt that Introductory Logic/ w DVD did an excellent job of grounding him in logic principles. The intermediate book he loved, I hated. Dad had to help with this one. It was more about symbolic logic and looked like something out of a mathbook nightmare I tried to supress (I am more of a language/ history kind of gal). This information is not found in any other book. Personally, I found this material confusing and would not subject my younger two to the frustration they would have experienced with it. Traditonal Logic II covered additional concepts my son also enjoyed although he liked the DVD's for Nance's program better. He felt that they were explained better. So in answer to your question, yes . You would learn something new in all of the books but you might want to choose between Introductory Logic and Traditional I.

My ds did both the Nance course and the TLI and TLII courses. I had him do Nance's courses during his 8th grade year, and he did the TL courses during his freshman year. Doing Nance's course first helped him with understanding TL. My dd only did TL I, and she struggled with it. I wished that I had taken her through the same sequence of books as I did with my ds.

I think you can do TL without the Nance course, but it is much easier if the dc has had previous logic exposure. It also gives the student a bigger view of the ways that logic is applied.

Just my two cents worth,

then she did TL I in 8th and TL II in 9th grade. Probably doing Intro. Logic (Nance's course) did help her with TL I, but she honestly liked TL I better. I did too---the layout was so much more "logical" than Intro. Logic, and very user-friendly.

Tina in Ouray and Charon are very good people on these boards to talk to about logic---they're both almost like logic professors! (Maybe they are in real life?)

Anyway, you might do a search on what both of them have had to say about logic. I personally much prefer Cothran's books, although I can see some benefit in doing Intro. and Intermediate Logic by Nance in 7th and 8th grade, and then doing TL I and TL II further on down.

One caution: TL II is a definite step above TL I, so make sure the concepts from TL I are down pat! There is also a fair amount of writing involved.
