Missing data are common with large scale assessments (LSAs). A typical approach to handling missing data with LSAs is the use of listwise deletion, despite decades of research showing that approach can be a suboptimal strategy resulting in biased estimates. In order to help researchers account for missing data, we provide a tutorial using R and…

The second objective is to propose a way to comprehend these common categories of meta-analysis through learning from their respective generic conceptual frameworks. The third objective is to point out which R…

This article examines an important and thorny problem in interview research: How to assess whether what people say motivated their actions actually did so? We ask three questions: What specific challenges are at play? How have researchers addressed them? And how should those strategies be evaluated? We argue that such research faces at least five…

What do we actually do when we research education policy and governance? Why do we tame the messy hinterland of research into smooth accounts and what do we lose in the process? In this volume, distinguished scholars in education policy and governance research discuss how the practice of methods is messy, subjective, and provisional. They approach…

Qualitative research (QR) has gained visibility and acceptance in the field of special education due to early efforts to identify quality indicators focused on technical and methodological aspects of QR. Whereas these indicators focused on credibility and trustworthiness of data, this article articulates additional QR quality indicators to enhance…

This powerful resource is for researchers and educational leaders who are interested in understanding and applying research methods that emphasize youth voice. The authors argue that most educational research either omits critical understandings of youth or, even worse, presents inaccuracies due to faulty techniques. Researching how youth…
