This investigation explored the extent to which a newly constructed instrument, the CLASS Action Survey (CLAS), was able to accurately measure the qualities of a specialized course, the Crystallized Learning and Academic Study System (CLASS) and its stated goals: (1) to increase college students' academic mindedness, (2) to challenge…

Wilcox, Bethany R.; Lewandowski, H. J. – Physical Review Physics Education Research, 2016
Student learning in instructional physics labs represents a growing area of research that includes investigations of students' beliefs and expectations about the nature of experimental physics. To directly probe students' epistemologies about experimental physics and support broader lab transformation efforts at the University of Colorado Boulder…

Pane, John F.; Griffin, Beth Ann; McCaffrey, Daniel F.; Karam, Rita – RAND Corporation, 2014
This addendum to previously published results presents alternative analyses of data from large-scale effectiveness studies of Cognitive Tutor Algebra I in middle schools and high schools. These alternative analyses produce results that are substantively the same as previously reported. We find a significant positive effect of 0.21 standard…

Raffeld, Paul; Reynolds, William M. – 1977
The pretest-posttest design referred to as Design 2 by Campbell and Stanley (1963) is commonly used in educational research and evaluation. The tenability of the assumption of a zero population difference commonly used with this design is questioned. A nonzero population estimate based on the mean difference observed in test-retest reliability…

Marston, Paul T., Borich, Gary D. – 1977
The four main approaches to measuring treatment effects in schools; raw gain, residual gain, covariance, and true scores; were compared. A simulation study showed true score analysis produced a large number of Type-I errors. When corrected for this error, this method showed the least power of the four. This outcome was clearly the result of the…
