Jeanipa,
As someone who tried really hard to find a home-based Spanish curriculum, I can say I just don’t think it’s possible to do well at home. Our goal for our homeschool is, as close to fluency as one can get without going abroad and being immersed in it.
We tried Tell Me More (like Rosetta Stone) and found it lacking in actual teaching of the grammar. Destinos; a video based curriculum. We also tried a local class, but the teacher just wasn’t a fit. My background of both high school and college Spanish were definitely buffed when we did Destinos, but it was very mom intensive for me to stay ahead of the curriculum. I was not up for that.
I looked into quite a few home-based curriculums (really wanting to keep Spanish on our schedule!) including Breaking the Barrier, which seems to be decent, and just didn’t feel that this was something that can be done well at home, alone (as in, no instructor or classmates to converse with). I was in discussions with a friend about a Spanish curriculum and she tried Breaking the Barrier and wasn’t thrilled. That may be one of the best option if you don’t want to do a live or online class.
After all our attempts at various curriculums we went back to La Clase Divertida live online (for high school). We used La Clase Divertida for elementary Spanish and just loved it. We have been very please with the online classes.
So I guess the bottom line is to know what your goal is for foreign language in your homeschool. Is it fluency or to meet a requirement for college? Lots of people have used home-based curriculum to fulfill college requirements.
