A high school teacher reports that her students don't believe they are supposed to think. All they understand is to look things up and repeat what they are told.

This was to some extent true when I was in high school, in the 1960s. People have a tendency to remember the "good old days" as better than they really were; the change may not be as great as that writer perceives it. But I can believe that it has got worse, due to standardized tests and search engines.
