Pre-registration and registered reports are two of the most promising open science practices for increasing transparency in the scientific process. Pre-registration involves publishing a timestamped record of a study design, ideally before data collection and analysis, so that research consumers can discern which analytic decisions were set a priori and which were changed after seeing data. Registered reports take the idea of pre-registration one step further, and provide peer review at the pre-registration stage. Researchers submit a Phase I manuscript that contains the introduction, background and context, and methods section of a study, and these Phase I manuscripts are peer reviewed. If reviewed positively, manuscripts are given in-principle acceptance, where the editors agree that if the researchers conduct the study as pre-registered--or document the deviations from their plan--the study will be published without regard for the direction or magnitude of findings. In this manner, studies are judged by whether they address important questions and use well-designed methods, not on the basis of reaching specific benchmarks for significance or effect size. This article illustrates the emerging range of approaches to pre-registration and registered reports with examples from a variety of studies and from the first special issue in educational research devoted to Registered Reports.PLEASE DO NOT CITE YET:This article is part of a forthcoming journal Special Issue on Open Science in Education and currently under review.
