Close reading is not a reading strategy, but an approach to reading.
"In the instructional context, the idea of close reading has been to shift the attention during the reading lesson off of strategies and skills and onto the texts and ideas. The notion is that if students are engaged in close reading throughout their education, they will develop a rich body of knowledge about the world and these reading practices will become habits of mind."
Close reading is an old, widely known and specific concept that indicates where meaning resides (in the text) and what readers must do to gain access to this meaning (read the text closely, weighing the author’s words and ideas, and relying heavily on the evidence in the text).
