    Dr Fox effect is a correlation observed between teacher expressiveness content coverage student evalutation and student acheivement
    In the observation two equivalent groups of students are given lectures varying in content coverage After the lecture students are required to evaluate the teacher on effectiveness A test is also taken to measure the student acheivement
    It is observed that student acheivement is higher for higher content-coverage However students are observed to rate high content-coverage lectures as better than low-coverage lectures only under conditions of low expressiveness Under conditions of high expressiveness no correlation is observed
    This lack of correspondance between content-coverage and ratings under conditions of high expressiveness is known as the Dr Fox Effect
