Scientific research provides a reliable means for developing and accumulating knowledge bases to guide policy and practice. However, evidence from meta-research and large-scale replication projects suggests that the published research base likely reflects bias, which threatens the validity and credibility of research-based recommendations. Moreover, there is limited accessibility to research reports, which limits the impact and application of scientific research. In this chapter, we propose that open-science reforms, which aim to make the research process as open and transparent as possible, can be applied to help address these issues. We describe and discuss four open-science practices -- preregistration and Registered Reports, open data and materials, open peer review, and open access and preprints -- and propose that they may become one of the next big things in special education research.
