"Using Power Tables to Compute Statistical Power in Multilevel Experimental Designs"
Practical Assessment, Research & Evaluation Vol. 14, No. 10 (May 2009)
Power computations for one-level experimental designs that assume simple random samples are greatly facilitated by power tables such as those presented in Cohen's book about statistical power analysis. However, in education and the social sciences...

The effect of interim assessments on the achievement gap in grades K-8: Evidence from the U.S
Spyros Konstantopoulos; Wei Li; Shazia R Miller; Arie van der Ploeg
International Journal of Educational Research Vol. 83, No. 1 (2017) pp. 160–180
This study investigated interim assessments effects on the achievement gap. The data were collected from a field experiment conducted in 2010–2011 in K-8 public schools in Indiana in the U.S. Two-level models were utilized to determine whether...
Comparing the Impact of Online and Face-to-Face Professional Development in the Context of Curriculum Implementation
Barry Fishman; Spyros Konstantopoulos; Beth W. Kubitskey; Richard Vath; Gina Park; Heather Johnson; Daniel C. Edelson
Journal of Teacher Education Vol. 64, No. 5 (2013) pp. 426–438
This study employed a randomized experiment to examine differences in teacher and student learning from professional development (PD) in two modalities: online and face-to-face. The study explores whether there are differences in teacher knowledge...

Examining study attrition: Implications for experimental research on professional development
Beth W. Kubitskey; Richard J. Vath; Heather J. Johnson; Barry J. Fishman; Spyros Konstantopoulos; Gina J. Park
Teaching and Teacher Education: An International Journal of Research and Studies Vol. 28, No. 3 (April 2012) pp. 418–427
As teacher professional development research includes more experimental designs, new challenges arise. We examine the threat of participant attrition as an example of the types of problems researchers face. Counter-intuitively, higher levels of...
