Experimental and Quasi-Experimental Designs for Research


Book Description

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.




Quasi-Experimentation


Book Description

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.




Distant Connections: The Memory Basis of Creative Analogy


Book Description

Analogical thinking lies at the core of human cognition, pervading from the most mundane to the most extraordinary forms of creativity. By connecting poorly understood phenomena to learned situations whose structure is well articulated, it allows reasoners to expand the boundaries of their knowledge. The first part of the book begins by fleshing out the debate around whether our cognitive system is well-suited for creative analogizing, and ends by reviewing a series of studies that were designed to decide between the experimental and the naturalistic accounts. The studies confirm the psychological reality of the surface bias revealed by most experimental studies, thus claiming for realistic solutions to the problem of inert knowledge. The second part of the book delves into cognitive interventions, while maintaining an emphasis on the interplay between psychological modeling and instructional applications. It begins by reviewing the first generation of instructional interventions aimed at improving the later retrievability of educational contents by highlighting their abstract structure. Subsequent chapters discuss the most realistic avenues for devising easily-executable and widely-applicable ways of enhancing access to stored knowledge that would otherwise remain inert. The authors review results from studies from both others and their own lab that speak of the promise of these approaches. ​




Experiment and Tradition in Primary Schools


Book Description

First published in 1966, Experiment and Tradition in Primary Schools was written to provide an account of the author’s pioneering study of the attainment of young children in schools where the curriculum was shaped by their spontaneous interests. The book describes the findings of Gardner’s work and assesses them in detail. It will have lasting relevance for those with an interest in the history of education and the development of education in infant and junior schools.




Experimental Design Research


Book Description

This book presents a new, multidisciplinary perspective on and paradigm for integrative experimental design research. It addresses various perspectives on methods, analysis and overall research approach, and how they can be synthesized to advance understanding of design. It explores the foundations of experimental approaches and their utility in this domain, and brings together analytical approaches to promote an integrated understanding. The book also investigates where these approaches lead to and how they link design research more fully with other disciplines (e.g. psychology, cognition, sociology, computer science, management). Above all, the book emphasizes the integrative nature of design research in terms of the methods, theories, and units of study—from the individual to the organizational level. Although this approach offers many advantages, it has inherently led to a situation in current research practice where methods are diverging and integration between individual, team and organizational understanding is becoming increasingly tenuous, calling for a multidisciplinary and transdiscipinary perspective. Experimental design research thus offers a powerful tool and platform for resolving these challenges. Providing an invaluable resource for the design research community, this book paves the way for the next generation of researchers in the field by bridging methods and methodology. As such, it will especially benefit postgraduate students and researchers in design research, as well as engineering designers.




Tradition and Experiment


Book Description




Experimental


Book Description

A compelling revision of the history of experimental writing from Pound and Stein to Language poetry, disclosing its uses and its limits. In this bold new study of twentieth-century American writing and poetics, Natalia Cecire argues that experimental writing should be understood as a historical phenomenon before it is understood as a set of formal phenomena. This seems counterintuitive because, at its most basic level, experimental writing can be thought of as writing which breaks from established forms. Touching on figures who are not typically considered experimental, such as Stephen Crane, Jacob Riis, Busby Berkeley, Ursula K. Le Guin, and Gottlob Frege, Experimental offers a fresh look at authors who are often treated as constituting a center or an origin point of an experimental literary tradition in the United States, including Gertrude Stein, Ezra Pound, William Carlos Williams, and Marianne Moore. In responding to a crisis of legitimization in the production of knowledge, this tradition borrows and transforms the language of the sciences. Drawing upon terminology from the history of science, Cecire invokes the epistemic virtue, which tethers ethical values to the production of knowledge in order to organize diverse turn-of-the-century knowledge practices feeding into "experimental writing." Using these epistemic virtues as a structuring concept for the book's argument, Cecire demonstrates that experimental writing as we now understand it does not do experiments (as in follow a method) but rather performs epistemic virtues. Experimental texts embody the epistemic virtues of flash, objectivity, precision, and contact, associated respectively with population sciences, neuroanatomy, natural history and toolmaking, and anthropology. Yet which virtues take precedence may vary widely, as may the literary forms through which they manifest. Bringing it up to the 1980s, Cecire reveals the American experimental literary tradition as a concerted and largely successful rewriting of twentieth-century literary history. She shows how the Language poets, a group of primarily white experimental writers, restored to the canon what they saw as modernism's true legacy, whose stakes were simultaneously political and epistemological: it produced a poet who was an intellectual and a text that was experimental.







Experimental and Quasi-experimental Designs for Generalized Causal Inference


Book Description

Sections include: experiments and generalised causal inference; statistical conclusion validity and internal validity; construct validity and external validity; quasi-experimental designs that either lack a control group or lack pretest observations on the outcome; quasi-experimental designs that use both control groups and pretests; quasi-experiments: interrupted time-series designs; regresssion discontinuity designs; randomised experiments: rationale, designs, and conditions conducive to doing them; practical problems 1: ethics, participation recruitment and random assignment; practical problems 2: treatment implementation and attrition; generalised causal inference: a grounded theory; generalised causal inference: methods for single studies; generalised causal inference: methods for multiple studies; a critical assessment of our assumptions.




Freedom Time


Book Description

"In Freedom Time, Anthony Reed reclaims the power of black experimental poetry and prose by arguing that if literature fundamentally serves the human need for freedom in expression, then readers and critics must see it as something other than a reflection of the politics of social protest and identity formation. Prior to the successful campaigns against Jim Crow segregation in the U.S. and colonization in the Caribbean, literary politics seemed much more obviously interventionist. As more African Americans and Afro-Caribbean writers gained access to formal political power, more writing emerged whose political concerns went beyond improving racial representation, appealing for social recognition, raising consciousness, or commenting on the political disillusion and fragmentation of the post-segregation and post-colonial moments. Through formal innovation and abstraction, writers increasingly pushed the limits of representation and expression in order to extend the limits of thought and literary possibility. Reed offers a theoretical account of this new "black experimental writing," which is at once a literary historical development, and a concept with which to analyze the ways writing engages race and the possibilities of expression. One of his key interventions is arguing that form drives the politics literature, not vice-versa. Through extended analyses of works by N. H. Pritchard, NourbeSe Philip, Kamau Brathwaite, Claudia Rankine, Douglas Kearney, Harryette Mullen, Suzan-Lori Parks and Nathaniel Mackey, Freedom Time draws out the political implication of their innovative approaches to literary aesthetics"--
