This report summarizes the complex research literature on quantitative methods for assessing how impacts of educational interventions on instructional practices and student learning differ across students, educators, and schools. It also provides technical guidance about the use and interpretation of these methods. The research topics addressed…

This paper analyzes 12 recent within-study comparisons contrasting causal estimates from a randomized experiment with those from an observational study sharing the same treatment group. The aim is to test whether different causal estimates result when a counterfactual group is formed, either with or without random assignment, and when statistical…

This chapter argues for the value of sibling research in addressing behavioral genetic issues on the etiology of individual differences. The goal of the report is to provide a set of simple and practical examples of sibling analyses in order to highlight the importance of incorporating siblings in future research. It begins with a discussion of…

Contrasts aptitude by treatment interaction (ATI) and hierarchical linear modeling (HLM) methods for making cross-level inferences between individual-level and group-level factors in school effectiveness research. Recommends HLM when intraclass correlations are high. ATI is suitable when intraclass correlations are low, but partitioning the…

An integrative causal process model of evaluation utilization variables is presented. The model was developed through a traditional approach to literature review that lists results from published studies and relates these to the research topic, and through an approach that tries to integrate the models found in the literature search. Meta-modeling…

Summarizes the main theoretical frameworks attempting to explain the causal mechanisms connecting marital conflict to child adjustment. Outlines the implications of accumulated gender-related research findings for each theoretical framework. Argues that gender may be a moderator of many of the mechanisms outlined in existing theoretical frameworks…
