The Determination of the Significance of Change Between Pre- and Posttesting Periods
Linn, Robert L.; Slinde, Jeffrey A.
Review of Educational Research, 47, 1, 121-150, Win 77

Where appropriate, regression analyses that treat the pretest no differently from other independent variables, and the posttest as the dependent variable avoid many difficulties introduced by gain scores.
