Another approach, instrumentalism, colloquially termed "shut up and calculate", emphasizes the utility of theories as instruments for explaining and predicting phenomena.

It claims that scientific theories are black boxes with only their input (initial conditions) and output (predictions) being relevant. Consequences, notions and logical structure of the theories are claimed to be something that should simply be ignored and that scientists shouldn't make a fuss about (see interpretations of quantum mechanics). 

Close to instrumentalism is Constructivist epistemology according to which the main task of science is constructing models that can be given input and will give you an output that will predict the output given by the reality under same conditions accurately and validly enough.

Paul K Feyerabend advanced the idea of epistemological anarchism, which holds that there are no useful and exception-free methodological rules governing the progress of science or the growth of knowledge, and that the idea that science can or should operate according to universal and fixed rules is unrealistic, pernicious and detrimental to science itself.

Feyerabend advocates treating science as an ideology alongside others such as religion, magic and mythology, and considers the dominance of science in society authoritarian and unjustified. 

He also contended (along with Imre Lakatos) that the demarcation problem of distinguishing science from pseudoscience on objective grounds is not possible and thus fatal to the notion of science running according to fixed, universal rules.

Feyerabend also stated that science does not have evidence for its philosophical precepts, particularly the notion of Uniformity of Law and the Uniformity of Process across time and space.

Finally, another approach often cited in debates of scientific skepticism against controversial movements like "scientific creationism", is methodological naturalism. Its main point is that a difference between natural and supernatural explanations should be made, and that science should be restricted methodologically to natural explanations.

That the restriction is merely methodological (rather than ontological) means that science should not consider supernatural explanations itself, but should not claim them to be wrong either. Instead, supernatural explanations should be left a matter of personal belief outside the scope of science. 

Methodological naturalism maintains that proper science requires strict adherence to empirical study and independent verification as a process for properly developing and evaluating explanations for observable phenomena.

The absence of these standards, arguments from authority, biased observational studies and other common fallacies are frequently cited by supporters of methodological naturalism as criteria for the dubious claims they criticize not to be true science.

Working scientists usually take for granted a set of basic assumptions that are needed to justify the scientific method:

(1) that there is an objective reality shared by all rational observers;

(2) that this objective reality is governed by natural laws; 

(3) that these laws can be discovered by means of systematic observation and experimentation. 

Philosophy of science seeks a deep understanding of what these underlying assumptions mean and whether they are valid.

The belief that all observers share a common reality is known as realism. It can be contrasted with anti-realism, the belief that there is no valid concept of absolute truth such that things that are true for one observer are true for all observers. 

The most commonly defended form of anti-realism is idealism, the belief that the mind or consciousness is the most basic essence, and that each mind generates its own reality.

In an idealistic world-view, what is true for one mind need not be true for other minds.

There are different schools of thought in philosophy of science. 

The most popular position is empiricism, which claims that knowledge is created by a process involving observation and that scientific theories are the result of generalizations from such observations.

Empiricism generally encompasses inductivism, a position that tries to explain the way general theories can be justified by the finite number of observations humans can make and the hence finite amount of empirical evidence available to confirm scientific theories. 

This is necessary because the number of predictions those theories make is infinite, which means that they cannot be known from the finite amount of evidence using deductive logic only. Many versions of empiricism exist, with the predominant ones being bayesianism and the hypothetico-deductive method.

Empiricism has stood in contrast to rationalism, the position originally associated with Descartes, which holds that knowledge is created by the human intellect, not by observation.

A significant 20th-century version of rationalism is critical rationalism, first defined by Austrian-British philosopher Karl Popper. 

Popper rejected the way that empiricism describes the connection between theory and observation.

He claimed that theories are not generated by observation, but that observation is made in the light of theories and that the only way a theory can be affected by observation is when it comes in conflict with it.

Popper proposed falsifiability as the landmark of scientific theories, and falsification as the empirical method, to replace verifiability and induction by purely deductive notions.

Popper further claimed that there is actually only one universal method, and that this method is not specific to science: The negative method of criticism, trial and error.

It covers all products of the human mind, including science, mathematics, philosophy, and art.

Memahami Pendidikan Sains

Science (from Latin scientia, meaning "knowledge") is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.

In an older and closely related meaning, "science" also refers to a body of knowledge itself, of the type that can be rationally explained and reliably applied. A practitioner of science is known as a scientist.

Since classical antiquity, science as a type of knowledge has been closely linked to philosophy. In the early modern period the words "science" and "philosophy of nature" were sometimes used interchangeably.

By the 17th century, natural philosophy (which is today called "natural science") was considered a separate branch of philosophy.

In modern usage, "science" most often refers to a way of pursuing knowledge, not only the knowledge itself. It is also often restricted to those branches of study that seek to explain the phenomena of the material universe.

In the 17th and 18th centuries scientists increasingly sought to formulate knowledge in terms of laws of nature such as Newton's laws of motion. And over the course of the 19th century, the word "science" became increasingly associated with the scientific method itself, as a disciplined way to study the natural world, including physics, chemistry, geology and biology. It is in the 19th century also that the term scientist was created by the naturalist-theologian William Whewell to distinguish those who sought knowledge on nature from those who sought other types of knowledge.

However, "science" has also continued to be used in a broad sense denoting reliable, teachable knowledge about a topic, as in modern terms like library science or computer science. 

This is also reflected in the names of some areas of academic study such as "social science" or "political science".
