In this commentary, we complement other constructive critiques of educational randomized control trials (RCTs) by calling attention to the commonly ignored role of context in causal mechanisms undergirding educational phenomena. We argue that evidence for the central role of context in causal mechanisms challenges the assumption that RCT findings…

Latent variable structural equation modeling has become the analytic method of choice in many domains of research in psychology and allied social sciences. One important aspect of a latent variable model concerns the relations hypothesized to hold between latent variables and their indicators. The most common specification of structural equation…

In this commentary, the author focuses on the use of design elements for increasing the severity of causal mediation tests. The estimation of causal mediation effects from observational data rests on rather stringent assumptions. In introducing and exemplifying ratio-of-mediator-probability weighting (RMPW), Hong and Nomi (henceforth HN) make…

The authors thank Dr. Lindsay Page for providing a nice illustration of the use of the principal stratification framework to define causal effects, and a Bayesian model for effect estimation. They hope that her well-written article will help expose education researchers to these concepts and methods, and move the field of mediation analysis in…

The focus of this paper is causal inference in social and educational research. A concern with causality has had a profound impact on the kinds of questions that may be addressed in research, on how they must be formulated, and on the methodology that must be applied. In the social sciences the prevailing experimental paradigm is used to address…

The terms "causal-comparative" and "correlational" are dated and misleading and suggest a false dichotomy in research. Textbook authors should stop misleading educational research students and researchers in training with the notion that causal-comparative research provides better evidence for causality than correlational research. They should…

Qualitative research exists in a time of global uncertainty. Around the world, governments are attempting to regulate scientific inquiry by defining what counts as "good" science. These regulatory activities raise fundamental, philosophical epistemological, political and pedagogical issues for scholarship and freedom of speech in the…

Asserts that both the Feuer, Towne, and Shavelson article on scientific culture and educational research and the recent National Research Council (NRC) report must be understood in the context of current federal discourse focused on experimentally derived causal explanations of educational program effectiveness. Notes that the NRC report risks…

Educational researchers are not engaged in discovering mechanistic universal truths sought by positivists or tidy prescriptions about what works. Instead, they provide guidelines and interpretive material to liberate the teacher's intelligence so that the teacher can use whatever ability he or she can achieve. (SLD)

F. Schrag is preoccupied with enhancing education, but who decides what enhancement is? He has confused positivism with empiricism. Positivism is a specific philosophical movement that is associated with logical positivism. The empiricism that Schrag labels positivism preceded the philosophic traditions. (SLD)
