 The authors discuss a number of possible explanations for this finding, including that instructors with higher SET scores may have concentrated their teaching on the common examinations in the course rather than giving students a deeper understanding for later courses.Hamermesh and West (2005) find that students at the University of Texas at Austin gave attractive instructors higher SET scores than less attractive instructors.However, the authors conclude that it may not be possible to determine if attractiveness increases the effectiveness of an instructor, possibly resulting in better learning outcomes.
