Sara, are you talking about the Videotext materials? After reading alot on both (because I was torn, too), at this juncture, barring any new developments that arise in the years between now and when my son is ready, I am going with the Videotext. My son will do well with a more rigorous math program; videotext is recommended by Jay Wile, whereas he stated that those who had used TT were not prepared for his upper level science courses and I expect my son to use the upper level courses. Now, my dd may or may not go that far, but since I do not like buying two different things, I”ll use it w/her as well, though I expect to move slower. It is incremental so I think she’ll do fine; if not, I’d consider TT for her, but hopefully I won’t have to buy two different things.
It seems to me that it will continue in the manner they are accustomed to from Dev. Math.; being that it is a mastery based method, which is what I was looking for. From what I’ve been able to find out, TT is presented in a very good way for understanding and is incremental. However, it’s not as “complete” in Algebra; doesn’t measure up in coverage, as the videotext, nor prepares you for college as well, from what I’ve read; not from the advertisements, but from users. The biggest complaint I’ve heard from Videotext users is that it would be nice to have more practice problems; so apparently the website has provided them for the student who needs them.
I think it depends upon the ultimate goals for your children that will determine your decision. I come away with the idea that TT is great for many families and thank G-d for it being out there because not every family is going into higher level maths/sciences. However, thankfully videotext is available for those of us who want something a little more rigorous and it’s incremental, mastery-based and someone else does the teaching besides me!
HTH,
Rachel
