Pygmalion in the Classroom

Pygmalion in the Classroom is a 1968 book by Robert Rosenthal and Lenore Jacobson about the effects of teacher expectation on first and second grade student performance. The idea conveyed in the book is that if teachers' expectations about student ability are manipulated early, those expectations will carry over to affect teacher behavior, which in turn will influence how the students will perform on an IQ test. Inducing high expectations in teachers will lead to high levels of IQ test performance. Inducing low expectations, will lead to low IQ test performance.
