In Chapter 2 we present evidence that scientific research in education accumulates just as it does in the physical, life, and social sciences. Consequently, we believe that such research would be worthwhile to pursue to build further knowledge about education, and about education policy and practice.
Science is an enormously successful human enterprise. The study of scientific method is the attempt to discern the activities by which that success is achieved. Among the activities often identified as characteristic of science are systematic observation and experimentation, inductive and deductive reasoning, and the formation and testing of hypotheses and theories.
How these are carried out in detail can vary greatly, but characteristics like these have been looked to as a way of demarcating scientific activity from non-science, where only enterprises which employ some canonical form of scientific method or methods should be considered science see also the entry on science and pseudo-science.
On the other hand, more recent debate has questioned whether there is anything like a fixed toolkit of methods which is common across science and only science. Scientific method should be distinguished from the aims and products of science, such as knowledge, predictions, or control.
Methods are the means by which those goals are achieved. Scientific method should also be distinguished from meta-methodology, which includes the values and justifications behind a particular characterization of scientific method i. Methodological rules are proposed to govern method and it is a meta-methodological question whether methods obeying those rules satisfy given values.
Finally, method is distinct, to some degree, from the detailed and contextual practices through which methods are implemented. The latter might range over: specific laboratory techniques; mathematical formalisms or other specialized languages used in descriptions and reasoning; technological or other material means; ways of communicating and sharing results, whether with other scientists or with the public at large; or the conventions, habits, enforced customs, and institutional controls over how and what science is carried out.
While it is important to recognize these distinctions, their boundaries are fuzzy. Hence, accounts of method cannot be entirely divorced from their methodological and meta-methodological motivations or justifications, Moreover, each aspect plays a crucial role in identifying methods. Disputes about method have therefore played out at the detail, rule, and meta-rule levels.
Changes in beliefs about the certainty or fallibility of scientific knowledge, for instance which is a meta-methodological consideration of what we can hope for methods to deliver , have meant different emphases on deductive and inductive reasoning, or on the relative importance attached to reasoning over observation i. Beliefs about the role of science in society will affect the place one gives to values in scientific method.
The issue which has shaped debates over scientific method the most in the last half century is the question of how pluralist do we need to be about method? Unificationists continue to hold out for one method essential to science; nihilism is a form of radical pluralism, which considers the effectiveness of any methodological prescription to be so context sensitive as to render it not explanatory on its own.
Some middle degree of pluralism regarding the methods embodied in scientific practice seems appropriate. But the details of scientific practice vary with time and place, from institution to institution, across scientists and their subjects of investigation. How significant are the variations for understanding science and its success? How much can method be abstracted from practice? This entry describes some of the attempts to characterize scientific method or methods, as well as arguments for a more context-sensitive approach to methods embedded in actual scientific practices.
This entry could have been given the title Scientific Methods and gone on to fill volumes, or it could have been extremely short, consisting of a brief summary rejection of the idea that there is any such thing as a unique Scientific Method at all. Both unhappy prospects are due to the fact that scientific activity varies so much across disciplines, times, places, and scientists that any account which manages to unify it all will either consist of overwhelming descriptive detail, or trivial generalizations.
The choice of scope for the present entry is more optimistic, taking a cue from the recent movement in philosophy of science toward a greater attention to practice: to what scientists actually do.
To some extent, different scientists at different times and places can be said to be using the same method even though, in practice, the details are different. For most of the history of scientific methodology the assumption has been that the most important output of science is knowledge and so the aim of methodology should be to discover those methods by which scientific knowledge is generated.
Science was seen to embody the most successful form of reasoning but which form? Section 2 surveys some of the history, pointing to two major themes. One theme is seeking the right balance between observation and reasoning and the attendant forms of reasoning which employ them ; the other is how certain scientific knowledge is or can be.
Section 3 turns to 20 th century debates on scientific method. In the second half of the 20 th century the epistemic privilege of science faced several challenges and many philosophers of science abandoned the reconstruction of the logic of scientific method. Views changed significantly regarding which functions of science ought to be captured and why. For some, the success of science was better identified with social or cultural features.
Historical and sociological turns in the philosophy of science were made, with a demand that greater attention be paid to the non-epistemic aspects of science, such as sociological, institutional, material, and political factors. Even outside of those movements there was an increased specialization in the philosophy of science, with more and more focus on specific fields within science.
The combined upshot was very few philosophers arguing any longer for a grand unified methodology of science. Sections 3 and 4 surveys the main positions on scientific method in 20 th century philosophy of science, focusing on where they differ in their preference for confirmation or falsification or for waiving the idea of a special scientific method altogether.
In recent decades, attention has primarily been paid to scientific activities traditionally falling under the rubric of method, such as experimental design and general laboratory practice, the use of statistics, the construction and use of models and diagrams, interdisciplinary collaboration, and science communication. Sections 4—6 attempt to construct a map of the current domains of the study of methods in science.
As these sections illustrate, the question of method is still central to the discourse about science. Scientific method remains a topic for education, for science policy, and among scientists.
It arises in the public domain where the demarcation of science is at issue. Some philosophers have recently returned, therefore, to the question of what it is that makes science a unique cultural product. This entry will close with some of these recent attempts at discerning and encapsulating the activities by which scientific knowledge is achieved. Attempting a history of scientific method compounds the vast scope of the topic. This section briefly surveys the background to modern methodological debates.
What can be called the classical view goes back to antiquity, and represents a point of departure for later divergences. Perhaps the most serious inhibition to the emergence of the history of theories of scientific method as a respectable area of study has been the tendency to conflate it with the general history of epistemology, thereby assuming that the narrative categories and classificatory pigeon-holes applied to the latter are also basic to the former.
To see knowledge about the natural world as falling under knowledge more generally is an understandable conflation. Histories of theories of method would naturally employ the same narrative categories and classificatory pigeon holes. An important theme of the history of epistemology, for example, is the unification of knowledge, a theme reflected in the question of the unification of method in science. Those who have identified differences in kinds of knowledge have often likewise identified different methods for achieving that kind of knowledge see the entry on the unity of science.
Related to the diversities of what is known, and how, are differences over what can be known. Plato — B. E distinguished the realms of things into the visible and the intelligible. Only the latter, the Forms, could be objects of knowledge. The intelligible truths could be known with the certainty of geometry and deductive reasoning.
What could be observed of the material world, however, was by definition imperfect and deceptive, not ideal. The Platonic way of knowledge therefore emphasized reasoning as a method, downplaying the importance of observation. Aristotle — B. E disagreed, locating the Forms in the natural world as the fundamental principles to be discovered through the inquiry into nature.
Aristotle is recognized as giving the earliest systematic treatise on the nature of scientific inquiry in the western tradition, one which embraced observation and reasoning about the natural world. In the Prior and Posterior Analytics , Aristotle reflects first on the aims and then the methods of inquiry into nature. A number of features can be found which are still considered by most to be essential to science.
For Aristotle, empiricism, careful observation but passive observation, not controlled experiment , is the starting point, though the aim is not merely recording of facts. The aims of discovery, ordering, and display of facts partly determine the methods required of successful scientific inquiry.
Also determinant is the nature of the knowledge being sought, and the explanatory causes proper to that kind of knowledge see the discussion of the four causes in the entry on Aristotle on causality. In addition to careful observation, then, scientific method requires a logic as a system of reasoning for properly arranging, but also inferring beyond, what is known by observation.
Methods of reasoning may include induction, prediction, or analogy, among others. In the Organon reasoning is divided primarily into two forms, a rough division which persists into modern times. The basic aim and method of inquiry identified here can be seen as a theme running throughout the next two millennia of reflection on the correct way to seek after knowledge: carefully observe nature and then seek rules or principles which explain or predict its operation.
The Aristotelian corpus provided the framework for a commentary tradition on scientific method independent of the science itself its physics and cosmos. In analysis, a phenomena was examined to discover its basic explanatory principles; in synthesis, explanations of a phenomena were constructed from first principles. During the Scientific Revolution these various strands of argument, experiment, and reason were forged into a dominant epistemic authority. The 16 th —18 th centuries were a period of not only dramatic advance in knowledge about the operation of the natural world—advances in mechanical, medical, biological, political, economic explanations—but also of self-awareness of the revolutionary changes taking place, and intense reflection on the source and legitimation of the method by which the advances were made.
The struggle to establish the new authority included methodological moves. The Book of Nature, according to the metaphor of Galileo Galilei — or Francis Bacon — , was written in the language of mathematics, of geometry and number. This motivated an emphasis on mathematical description and mechanical explanation as important aspects of scientific method.
Through figures such as Henry More and Ralph Cudworth, a neo-Platonic emphasis on the importance of metaphysical reflection on nature behind appearances, particularly regarding the spiritual as a complement to the purely mechanical, remained an important methodological thread of the Scientific Revolution see the entries on Cambridge platonists ; Boyle ; Henry More ; Galileo.
In Novum Organum , Bacon was critical of the Aristotelian method for proceeding too quickly and leaping from particulars to universals, largely as dictated by the syllogistic form of reasoning which regularly mixed those two types of propositions.
Bacon aimed at the invention of new arts, of principles, of designations and directions for works. The community of scientists could then climb, by a careful, gradual and unbroken ascent, to reliable general claims. Whewell would later criticize Bacon in his System of Logic for paying too little attention to the practices of scientists. It is to Isaac Newton — , however, that historians of science and methodologists have paid the greatest attention, by far.
Given the enormous success of his Principia Mathematica and Opticks , this is understandable. This was viewed mainly on the continent as insufficient for proper natural philosophy. The Regulae counter this objection, re-defining the aims of natural philosophy by re-defining the method natural philosophers should follow. The scientist was not to invent systems but infer explanations from observations, as Bacon had advocated.
This would come to be known as inductivism. In the century after Newton, significant clarifications of the Newtonian method were made. Colin Maclaurin — , for instance, reconstructed the essential structure of the method as having complementary analysis and synthesis phases, one proceeding away from the phenomena in generalization, the other from the general propositions to derive explanations of new phenomena.
The emphasis was often the same, as much on the character of the scientist as on their process, a character which is still commonly assumed. The scientist is humble in the face of nature, not beholden to dogma, obeys only his eyes, and follows the truth wherever it leads. It was certainly Voltaire — and du Chatelet — who were most influential in propagating the latter vision of the scientist and their craft, with Newton as hero. Scientific method became a revolutionary force of the Enlightenment.
See also the entries on Newton , Leibniz , Descartes , Boyle , Hume , enlightenment , as well as Shank for a historical overview. Not all 18 th century reflections on scientific method were so celebratory.
The Nature of Political Inquiry. As we begin our discussion of political science research methods is important to keep in mind that we are in fact studying social science and the scientific method. We might ask, ourselves in what way is political science a science? And, if my assertion that political science is a science is correct. We must differentiate between politics and political science.
The scientific method is an empirical method of acquiring knowledge that has characterized the development of science since at least the 17th century. It involves careful observation , applying rigorous skepticism about what is observed, given that cognitive assumptions can distort how one interprets the observation. It involves formulating hypotheses , via induction , based on such observations; experimental and measurement-based testing of deductions drawn from the hypotheses; and refinement or elimination of the hypotheses based on the experimental findings. These are principles of the scientific method, as distinguished from a definitive series of steps applicable to all scientific enterprises. Though diverse models for the scientific method are available, there is in general a continuous process that includes observations about the natural world.
In logic, we often refer to the two broad methods of reasoning as the deductive and inductive approaches. Deductive reasoning works from the more general to the more specific. We might begin with thinking up a theory about our topic of interest.
This article presents a reconstructed definition of the case study approach to research. This definition emphasizes comparative politics, which has been closely linked to this method since its creation. The article uses this definition as a basis to explore a series of contrasts between cross-case study and case study research. This article attempts to provide better understanding of this persisting methodological debate as a matter of tradeoffs, which may also contribute to destroying the boundaries that have separated these rival genres within the subfield of comparative politics.
Kakarot-Handtke, Egmont : The pure logic of value, profit, interest. Standard economic models are based on axioms that epitomize the fundamental behavioral assumptions. This approach is not conductive to convincing results. The suggested change of perspective is guided by the question: what is the minimum set of propositions for the consistent reconstruction of the evolving money economy? We start with three structural axioms and determine their real world implications.
Politics, in the largest sense, refers to the action of human beings in Society. The notion of Society can be gained only by each one's individual experience. The first example of it is the Family, which contains a plurality of persons in mutual co-operation, with command and obedience. The earliest notions of authority, law, command, obedience, punishment, superior, inferior, ruler, subject,are gained from the various aspects of the small domestic circle. The science of Politics, as a whole, is either Theoretical or Practical.
Take a minute to ponder some of what you know and how you acquired that knowledge. But should we trust knowledge from these sources? The methods of acquiring knowledge can be broken down into five categories each with its own strengths and weaknesses.

The author provides an overview about the field of international political economy IPE along metatheoretical lines. The IPE communities in the United States and Western Europe exhibit more differences than commonalities in their ontological, epistemological and methodological assumptions. While the U. The article ends with a view towards the future introducing three possible scenarios for the IPE sub-discipline. While the term 'political economy' has of course a formidable intellectual pedigree, IPE scholars came to associate themselves with this new label only during the s, when a group of political scientists defined IPE as an autonomous field of research apart from economics. The volume by Robert Keohane and Joseph Nye "Power and Interdependence"  emblematically signaled the arrival of the new sub-discipline within International Relations.
