Learn New Skills Actively … By doing things – acquiring new skills by applying new

methods to real data and answering real questions. By participating in a community whose members display

differing expertise, who model responsible behavior, and who offer feedback and mutual support.

Do What Humans Do Best … By planning data-analyses to address research questions

explicitly and appropriately. By guiding the computer as it does the legwork, and

making sure that it completes the work correctly. By checking the constraints (assumptions) under which the

work has been conducted, have been met. By interpreting and communicating work products for

members of your own, and nearby, communities.

In all areas of the law’s broad reach, including the big ticket items – teacher quality, safe and drug-free schools, and Title I – states and localities will have to demonstrate that they plan to spend those funds on programs with a scientific track record”

Uses methods appropriate to the research question that was posed.

Employs systematic empirical methods that draw on either observation or experiment.

Relies on measurements or observations that provide valid and reliable data.

Involves data analyses that can support the findings.

Makes causal claims only in random assignment experiments or in research designs that eliminate plausible competing explanations for the obtained results.

Is presented with sufficient clarity and detail to permit replication or, at a minimum, to permit others to build systematically on the research.

Obtains acceptance through a comparably rigorous, objective, and scientific review.
