Download or read book Quasi Experimentation written by Charles S. Reichardt and published by Guilford Publications. This book was released on 2019-09-02 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: Featuring engaging examples from diverse disciplines, this book explains how to use modern approaches to quasi-experimentation to derive credible estimates of treatment effects under the demanding constraints of field settings. Foremost expert Charles S. Reichardt provides an in-depth examination of the design and statistical analysis of pretest-posttest, nonequivalent groups, regression discontinuity, and interrupted time-series designs. He details their relative strengths and weaknesses and offers practical advice about their use. Reichardt compares quasi-experiments to randomized experiments and discusses when and why the former might be a better choice. Modern moethods for elaborating a research design to remove bias from estimates of treatment effects are described, as are tactics for dealing with missing data and noncompliance with treatment assignment. Throughout, mathematical equations are translated into words to enhance accessibility.

The book also reviews nonexperimental techniques, including a critical examination of evaluation methods that are observational rather than experimentalâ€"a necessity when randomized experiments are infeasible.
Download or read book Running Randomized Evaluations written by Rachel Glennerster and published by Princeton University Press. This book was released on 2013-11-24 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive guide to running randomized impact evaluations of social programs in developing countries This book provides a comprehensive yet accessible guide to running randomized impact evaluations of social programs. Drawing on the experience of researchers at the Abdul Latif Jameel Poverty Action Lab, which has run hundreds of such evaluations in dozens of countries throughout the world, it offers practical insights on how to use this powerful technique, especially in resource-poor environments. This step-by-step guide explains why and when randomized evaluations are useful, in what situations they should be used, and how to prioritize different evaluation opportunities. It shows how to design and analyze studies that answer important questions while respecting the constraints of those working on and benefiting from the program being evaluated. The book gives concrete tips on issues such as improving the quality of a study despite tight budget constraints, and demonstrates how the results of randomized impact evaluations can inform policy. With its self-contained modules, this one-of-a-kind guide is easy to navigate. It also includes invaluable references and a checklist of the common pitfalls to avoid. Provides the most up-to-date guide to running randomized evaluations of social programs, especially in developing countries Offers practical tips on how to complete high-quality studies in even the most challenging environments Self-contained modules allow for easy reference and flexible teaching and learning Comprehensive yet nontechnical
Download or read book Experimental and Quasi Experimental Designs for Research written by Donald T. Campbell and published by Ravenio Books. This book was released on 2015-09-03 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: We shall examine the validity of 16 experimental designs against 12 common threats to valid inference. By experiment we refer to that portion of research in which variables are manipulated and their effects upon other variables observed. It is well to distinguish the particular role of this chapter. It is not a chapter on experimental design in the Fisher (1925, 1935) tradition, in which an experimenter having complete mastery can schedule treatments and measurements for optimal statistical efficiency, with complexity of design emerging only from that goal of efficiency. Insofar as the designs discussed in the present chapter become complex, it is because of the intransigency of the environment: because, that is, of the experimenter’s lack of complete control.

Download or read book The Science of Evaluation written by Ray Pawson and published by SAGE. This book was released on 2013-02-01 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evaluation researchers are tasked with providing the evidence to guide programme building and to assess its outcomes. As such, they labour under the highest expectations - bringing independence and objectivity to policy making. They face huge challenges, given the complexity of modern interventions and the politicised backdrop to all of their investigations. They have responded with a huge portfolio of research techniques and, through their professional associations, have set up schemes to establish standards for evaluative inquiry and to accredit evaluation practitioners. A big question remains. Has this monumental effort produced a progressive, cumulative and authoritative body of knowledge that we might think of as evaluation science? This is the question addressed by Ray Pawson in this sequel to Realistic Evaluation and Evidence-based Policy. In answer, he provides a detailed blueprint for an evaluation science based on realist principles.

Download or read book Evaluability Assessment written by Michael S. Trevisan and published by SAGE Publications. This book was released on 2014-08-06 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evaluability assessment (EA) can lead to development of sound program theory, increased stakeholder involvement and empowerment, better understanding of program culture and context, enhanced collaboration and communication, process and findings use, and organizational learning and evaluation capacity building. Evaluability Assessment: Improving Evaluation Quality and Use, by Michael Trevisan and Tamara Walser, provides an up-to-date treatment of EA, clarifies what it actually is and how it can be used, demonstrates EA as an approach to evaluative inquiry with multidisciplinary and global appeal, and identifies and describes the purposes and benefits to using EA. Using case examples contributed by EA practitioners, the text illustrates important features of EA use, and showcases how EA is used in a variety of disciplines and evaluation contexts. This text is appropriate as an instructional text for graduate level evaluation courses and training, and as a resource for evaluation practitioners, policymakers, funding agencies, and professional training. “The most impressive aspect of this book is that it positions EA as an approach that perfectly fits within the current philosophical views on program evaluation… The authors do a great job connecting these theories to practice, and provide good guidelines.” —Sebastian Galindo-Gonzalez, University of Florida “This book is focused on one very important topic in the scope of program evaluation content. It establishes the foundation for a variety of applications: impact assessment, program development, and formative evaluation. This text provides new insights and methods for conducting evaluability assessment.” —S. Kim MacGregor, Louisiana State University “The book is written in a very readable style, is well organized and referenced. I like the inclusion of case studies, guidelines for actually doing EA, and the extensive discussion of its alignment with other models of evaluation process.” —Iris Smith, Emory University
