"People with disabilities are not the only ones being left behind." I agree, but this is not new. For decades educators have agrued that they will remain behind until someone pays extra "to educate" people with disabilities.
Technically, that's false, but frequently asserted claim.
Experimental empirical behavioral research scientists who provide the strongest data available have demonstrated in various ways for over 100 years that all people learn the same way: one step at a time through their senses by trial and error using a finite set of observable, measurable, behavior patterns. It is technically possible to watch a learner identify and use various ways to meet criteria to show that someone learn learned something.
All state certified educators have been at least exposed to these facts during preparation for certification, even when they have not read the original published research reports. That means either they did not learn their lessons, or they have chosen to ignore these facts.
Internet blogs (excluding this one) by teachers show repeatedly that they choose to ignore and argue against this view. Students with and without disabilities pay the price for the ignorance of these educators. (I use the word ignorance as a descriptor, not a value conclusion.)
With few exceptions, educators demonstrate and standardized tests document that they do not use behavioral patterns of learning to arrange lessons so all students meet minimum state standards for any lesson.
So, yes, some schools fall apart and leave most students behind, fundamentally because educators fail to build lessons from scientific facts. But bricks-and-morter schools are not necessary to increase learning.
Private entrepreneurs are demonstrating how the use of behavioral science reports over the Internet increases learning rates promptly.
Given this view, some education policy mavens have frequently wondered over the past 5 decades when someone will challenge the procedures of public school educators as perpitrating a massive fraud against funders.
Yes?
