Semistructured interviews involve an interviewer asking some prespecified, open-ended questions, with follow-up questions based on what the interviewee has to say. This Reflections on Methodology post describes a semistructured interview protocol recently used to explore how children who experience poverty perceive their situations, their economic status, and public benefit programs.
A Literature Review
Examining the scholarly literature published since a seminal review in 2000, this working paper discusses the principles that underlie project-based learning, how it has been used in K-12 settings, the challenges teachers have confronted in implementing it, and what is known about its effectiveness in improving students’ learning outcomes.
Using data from the Head Start Impact Study, this paper examines variation in Head Start effects across individual children, policy-relevant subgroups of children, and Head Start centers. It finds that past estimates of the average effect of Head Start programs mask a wide range of relative program effectiveness.
The city’s small, academically nonselective high schools have substantially improved graduation rates for disadvantaged students. This report demonstrates that, because more of their students graduate and do so within four years, the schools have lower costs per graduate than the schools their study counterparts attended.
An Empirical Assessment Based on Four Recent Evaluations
This reference report, prepared for the National Center for Education Evaluation and Regional Assistance of the Institute of Education Sciences (IES), uses data from four recent IES-funded experimental design studies that measured student achievement using both state tests and a study-administered test.
In some experimental evaluations of classroom- or school-level interventions, random assignment is conducted at the student level and the program is delivered at the higher level. This paper clarifies the correct causal interpretation of “program impacts” when this study design is used and discusses the implications and limitations of this research design. A real example is used to demonstrate the paper’s key points.
This report presents a preliminary analysis of the cost of operating Britain’s Employment Retention and Advancement (ERA) demonstration, which is being evaluated though a large-scale randomised control trial. This assessment of costs will become an important element of the full cost-benefit analysis to be presented in future ERA reports.
This paper illustrates how to design an experimental sample for measuring the effects of educational programs when whole schools are randomized to a program and control group. It addresses such issues as what number of schools should be randomized, how many students per school are needed, and what is the best mix of program and control schools.
