I wrote a blog post about this... https://www.flipflopspanish.com/blogs/news/what-about-learning-spanish-through-immersionBut I love the analogy of "drinking from a fire hose" or "listening to static on a radio."As always, the x+1 theory keeps proving itself out. Without a foundation, immersion is TOO MUCH. It's all static. With a little foundation, immersion BEGINS to help...Another analogy, think of learning some vocabulary and how to put sentences together in a class, or from a curriculum as  the stretching part of an exercise regiment. Without it, you create LOTS of obstacles, or at the very least can't perform at your best.... at the worst, you really harm yourself - making you think you "can't" do it, or "it's too hard" ... or something even worse, the students doubts his intelligence or ability.So. No, I'm NOT a fan of immersion alone. Begin with something simple and fun... and maybe that something is See it and Say it for you!
