Consortium for the Advancement of Special Education Research (CASPER)
CASPER’s mission is to advance open science in special education and related fields by (a) conducting meta-research, (b) providing recommendations and resources, and (c) conducting and disseminating open research.
- Less than 1% of articles published in special education journals are replication studies -- Lemons et al., 2016; Makel et al. (2016)
- 4% of intervention studies in special education and related fields reported solely null findings – Kittelman et al., 2018; Therrien and Cook (2018)
- Published single-case design studies examining pivotal response theory for individuals with autism reported 22% larger effects than unpublished studies – Sham and Smith (2014)
- 4-15% of single-case design researchers reported they would drop one or two cases with small effects from a study before submitting it for publication – Shadish, Zelinsky, Vevea, and Kratochwill, 2016
