Alfred Binet was convinced to conduct research into graphology from to He called it "the science of the future" despite rejection of his results by graphologists.

However, the Glass and Smith study was criticized e.

Some subsequent reviews reached conclusions similar to Glass and Smith e. In the midst of controversy, the Tennessee state legislature asked just this question and funded a randomized experiment to find out, an experiment that Harvard statistician Frederick Mostellerp.

The experiment began with a cohort of students who entered kindergarten inand lasted 4 years. After third grade, all students returned to regular size classes. Although students were supposed to stay in their original treatment conditions for four years, not all did.

Three findings from this experiment stand out. First, students in small classes outperformed students in regular size classes with or without aides.


Second, the benefits of class-size reduction were much greater for minorities primarily African American and inner-city children than others see, e. And third, even though students returned to regular classes in fourth grade, the reduced class-size effect persisted in affecting whether they took college entrance examinations and on their examination performance Krueger and Whitmore, New theories about the periodicity of the ice ages, similarly, were informed by multiple methods e.

The integration and interaction of multiple disciplinary perspectives—with their varying methods—often accounts for scientific progress Wilson, ; this is evident, for example, in the advances in understanding early reading skills described in Chapter 2.

This line of work features methods that range from neuroimaging to qualitative classroom observation. Page 66 Share Cite Suggested Citation: This is true for many research endeavors in the social sciences and education research, although not for all of them.

If the concepts or variables are poorly specified or inadequately measured, even the best methods will not be able to support strong scientific inferences. The history of the natural sciences is one of remarkable development of concepts and variables, as well as the tools instrumentation to measure them.

Measurement reliability and validity is particularly challenging in the social sciences and education Messick, Sometimes theory is not strong enough to permit clear specification and justification of the concept or variable.

Sometimes the tool e. Sometimes the use of the measurement has an unintended social consequence e. And sometimes error is an inevitable part of the measurement process. In the physical sciences, many phenomena can be directly observed or have highly predictable properties; measurement error is often minimal.

However, see National Research Council [] for a discussion of when and how measurement in the physical sciences can be imprecise. In sciences that involve the study of humans, it is essential to identify those aspects of measurement error that attenuate the estimation of the relationships of interest e.

By investigating those aspects of a social measurement that give rise to measurement error, the measurement process itself will often be improved. Regardless of field of study, scientific measurements should be accompanied by estimates of uncertainty whenever possible see Principle 4 below.

SCIENTIFIC PRINCIPLE 4 Provide Coherent, Explicit Chain of Reasoning The extent to which the inferences that are made in the course of scientific work are warranted depends on rigorous reasoning that systematically and logically links empirical observations with the underlying theory and the degree to which both the theory and the observations are linked to the question or problem that lies at the root of the investigation.

This chain of reasoning must be coherent, explicit one that another researcher could replicateand persuasive to a skeptical reader so that, for example, counterhypotheses are addressed. All rigorous research—quantitative and qualitative—embodies the same underlying logic of inference King, Keohane, and Verba, This inferential reasoning is supported by clear statements about how the research conclusions were reached: What assumptions were made?

How was evidence judged to be relevant?

How were alternative explanations considered or discarded? How were the links between data and the conceptual or theoretical framework made? The nature of this chain of reasoning will vary depending on the design of the study, which in turn will vary depending on the question that is being investigated.

Will the research develop, extend, modify, or test a hypothesis? Does it aim to determine: How does it work? Under what circumstances does it work? If the goal is to produce a description of a complex system, such as a subcellular organelle or a hierarchical social organization, successful inference may rather depend on issues of fidelity and internal consistency of the observational techniques applied to diverse components and the credibility of the evidence gathered.Science is a systematic and logical approach to discovering how things in the universe work.

It is also the body of knowledge accumulated through the discoveries about all the things in the universe. The principles for conducting clinical research have evolved from centuries of experience and are based not only on biomedical science but also on ethical, legal, regulatory, and social issues.

Milestones from the history of science and medicine in this chapter emphasize the contributions that clinical research has ultimately made to advances.

In accordance with established principles of science, scientists have the responsibility to replicate and reconfirm their results as a normal part of the research process. These principles cut across two dimensions of the scientific enterprise: the creativity, expertise, communal values, and good judgment of the people who “do” science; and generalized guiding principles for scientific inquiry.
