From a parenting perspective, I'd rather have a school who was willing to adapt and change to suit the broader needs of their class as opposed to sticking to any one formula for teaching, because if they do, they aren't meeting the needs of their students properly and being the best teacher they can be. Some kids need structure and can't handle investigative/inquiry learning. Some kids thrive on doing their own thing and finding their own answers. A good teacher will know that and structure things accordingly. Of course if you have a class of 30 kids that gets harder to do, but it's still possible. The teacher needs to be able to engage kids because that's the most important thing because if kids aren't engaged, that's when teaching time and learning is lost. So I want a teacher that can do that, using any method, because if my kids are engaged in what they are doing, then they are learning.
