Definitely worth reading! In answer to the question above, the author writes YES. Constructivism favors discovery learning, not ‘research-based’ structured learning–as for reading. It’s pretty clear that if students are taught phonetics and other attributes of reading early, then many of them will not need special education.
Interestingly, a statistic that caught my eye recently is this: In Finland by the age of 16, 60% of students have had “special education.” By which Finland means, focused attention on the elements of learning basic reading, writing and math. Perhaps the Finns and this author are on to something important. A worthy read.
