I don't think schools ____________ very much in the next few years.

When creating a sentence about the future of schools, there are a few ways you could structure it depending on the context and the meaning you wish to convey. You may want to express certainty, possibility, or speculation. Here are several ways to complete your sentence using different modal verbs and tenses:

1. Certainty (if you are certain that schools won't change):

   • "I don't think schools will change very much in the next few years."
   • "I don't think schools are going to change very much in the next few years."

2. Possibility (if you believe there is a possibility that schools may or may not change):

   • "I don't think schools might change very much in the next few years."
   • "I don't think schools could change very much in the next few years."

3. Speculation (if you are speculating about future changes):

   • "I don't think schools will have changed very much in the next few years."

Keep in mind that grammatically, "might" and "could" suggest less certainty than "will". Determining the right form depends on the speaker's perspective and the intended nuance of the sentence. However, the most common choice for making predictions about the future is typically "will," especially when you want to express a firm opinion or belief.
