I am concerned by the use of "monitoring" in this sentence - the author seems to be suggesting that "well-meaning teachers" are training students to compare themselves and wonder "how good they are" as they read. In fact, monitoring as a reading skill is a strategic element of metacognitive regulation. (Flavell, 1979, 1987; Schraw & Dennison, 1994, in TEAL Center Fact Sheet No. 4, Metacognitive Processes, Adult Education and Literacy, U.S. Department of Education) Readers are taught to occasionally monitor their understanding of a text as they read (Do I still understand what's going on?) to ensure overall comprehension. Kohn worries that students will monitor themselves out of their reading enjoyment - but students can't enjoy what they are reading if they can't understand the text.
