Siegfried Engelmann from the University of Oregon developed a science based method for teaching reading. With simple ideas like making sure the letters were distinguishable, teaching the most common letters first, teaching the sounds the letters make before teaching the names of the letters, immediate feedback on reading mistakes, etc...
I've seen many "science based methods" in my lifetime, and they are contradictory. I am not an expert in the subject of education, which means I cannot evaluate what is really science based. I could do this of course - but my day job is as a programmer and when I'm done with that I just want to make sawdust or music, not do more research.
Sure, but all methods teach kids to read. Science of education should include effectiveness. Things such as how well they comprehend, how fast they read, what disabilities they have... note that the above list logically should be in conflict and society should debate the best method bases on the different measures to find good compromises.
