The features of education, in combination with the guiding principles of science, set the boundaries for the design of scientific education research. The design of a study does not make the study scientific. A wide variety of legitimate scientific designs are available for education research. They range from randomized experiments of voucher programs to in-depth ethnographic case studies of teachers to neurocognitive investigations of number learning using positive emission tomography brain imaging.
To be scientific, the design must allow direct, empirical investigation of an important question, account for the context in which the study is carried out, align with a conceptual framework, reflect careful and thorough reasoning, and disclose results to encourage debate in the scientific community.
Moreover, the committee was not charged with, nor did we attempt to develop, a comprehensive blueprint for federal education research agency; that work is best left to organizational design experts and the political process. Rather, the committee developed six design principles for a federal education research agency to nurture a scientific culture within the agency. The precise structure itself is not the critical element.
To develop such a scientific culture, the agency must have an infrastructure that is insulated from political micromanagement, supported by sufficient and sustained resources, and led by staff with top scientific and management credentials who have the flexibility to make decisions and are accountable for them. Importantly, responsibility for the success of such an agency lies with all education stakeholders.
The government cannot mandate a healthy federal role. Even more commonly, scientists design experiments Part 6 based on mega-theories and sub-theories that already are accepted, with the goal of simply making observations so they can learn more about nature.
The dual-parallel shape of the hypothetico-deductive "box" whose 4 corners are defined by the model and system, predictions and observations symbolizes two parallel relationships. The left-side process done by mentally running a theory-based model parallels the right-side process done by physically running a real-world experimental system. There is also a parallel between the top and bottom of the box.
At the top, a hypothesis is a claim that the model and system are similar in some respects and to some degree of accuracy. But a theory can be false even if its predictions agree with observations, so it is necessary to supplement this "agreement logic" with another criterion, the degree of predictive contrast, by asking "How much contrast exists between the predictions of this theory and the predictions of plausible alternative theories?
Estimates for these two evaluation criteria degree of agreement and degree of predictive contrast are combined to form an empirical evaluation of current hypothesis. This evaluation and the analogous empirical evaluations of previous hypotheses that are based on the same theory as the current hypothesis, so both previous-and-current can be used to evaluate this theory are empirical factors that influence evaluation of the theory.
Conceptual Factors in Theory Evaluation In ISM the conceptual factors that influence theory evaluation are split into internal characteristics and external relationships. Scientists expect a logical internal consistency between a theory's own components. And when evaluating a theory's logical structure, one common criteria is simplicity, which is achieved by postulating a minimum number of logically interconnected theory-components.
Also, in each field of science there are expectations for the types of entities and actions that should and should not be included in a theory. These "expectations about components" can be explicit or implicit, due to scientists' beliefs about ontology what exists or utility what is useful.
The external relationships between theories including both scientific and cultural-personal theories can involve an overlapping of domains or a sharing of theory components.
Theories with domains that overlap are in direct competition because they claim to explain the same systems. Theories with shared components often provide support for each other, and can help to unify our understanding of the domains they describe.
There is some similarity between the logical structures for a theory composed of smaller components and for a mega-theory composed of smaller theoriesand many conceptual criteria can be applied to either internal structure within a theory or external relationships between theories in a mega-theory. Cultural-Personal Factors in Theory Evaluation During all activities of science, including theory evaluation, scientists are influenced by cultural-personal factors.
Scientific Method - in Education, for Understanding
These five factors interact with each other, and operate in a complex social context that involves individuals, the scientific community, and society as a whole. Science and culture are mutually interactive, with each affecting the other.
The effects of culture, on both the process of science and the content of science, are summarized at the top of the ISM diagram: Thought Styles Some cultural-personal influence is due to a desire for personal consistency between ideas, between actions, and between ideas and actions. For example, scientists are more likely to accept a scientific theory that is consistent with their metaphysical and ideological theories.
In the diagram this type of influence appears as a conceptual factor, external relationships All of these cultural-personal factors vary in different areas of science and in communities within each area, and for different individuals, so the types and amounts of resulting influences on the process of science and the content of science vary widely.

Theory Evaluation A theory is evaluated in association with supplementary theories, and relative to alternative theories. Based on their estimate of a theory's status — which can be anywhere along a range from very low to very high, since in ISM the word "theory" doesn't imply that support is weak or strong — scientists can decide to retain this theory with no revisions, revise it to generate a modified new?
When a theory is retained after evaluation, its status can be increased, decreased, or unchanged. According to formal logic it is impossible to prove a theory is either true or false, but scientists have developed analytical methods that encourage them to claim a "rationally justified confidence" for their conclusions about status.
Each theory has two types of status: Theory Generation Generating a theory can involve selecting an old theory or, if necessary, inventing a new theory. The process of inventing a new theory usually occurs by revising an existing "old theory.
Often, a creative analysis of data to search for patterns is a key step in constructing a theory. Theory generation is guided by evaluation factors that are cultural-personal, conceptual, and empirical. There is a close relationship between the generation and evaluation of a theory. If there is data from several experiments, retroduction can aim for a theory whose predictions are consistent with all known data.

During retroduction a scientist, curious about puzzling observations and motivated to find an explanation, can adjust either of the two sources used to construct a model: Usually, a scientific "inference to the best explanation" involves a creative use of logic that is both inductive and deductive. With retroduction or hypothetico-deduction which are similar, except that in retroduction a model is proposed after the observations are knownsimilar logical limitations apply.
Even if a theory correctly predicts the observations, plausible alternative theories might make the same correct predictions, so with either retroduction or hypothetico-deduction there is a cautious conclusion: This caution contrasts with the definite conclusion of deductive logic: Experimental Design Generation-and-Evaluation In ISM an "experiment" is defined broadly to include both controlled experiments and field studies.
Three arrows point toward generate experiment, showing inputs from theory evaluation which can motivate-and-guide a designing of experimentsgaps in system-knowledge that can be filled by experimentation, and provide motivation and "do thought experiments
