While most faculty welcome questions from students in or out of class, it is generally not in the culture of college science courses for students to share their confusions; rather, there is a focus on right answers and on being scientifically correct (Tobias, 1990; Steele and Aronson, 1995; Seymour and Hewitt, 1997). Simply giving students permission to be confused is one way to provide the impetus for students to be metacognitive and to ask themselves what they do not understand. Sometimes all that is required is for an instructor to explicitly share with students that an upcoming topic has proved confusing to students in the past and that confusion is to be expected. Even slight alterations in the verbal directions for course activities could serve to give students the license to share and display what is confusing to them, as opposed to hiding it. For example, during in-class pair discussion of a clicker question, the direction to not only compare chosen answers with a colleague but also to pose one question that relates to something you found confusing about the question could immediately increase the willingness and comfort level of students to discuss confusion, which demands them to be metacognitive during the activity.

This analysis of the STEM workforce relies on a broad-based definition of those working in science, technology, engineering and math (STEM). STEM jobs are defined solely based on occupation and include any of 74 standard occupations in life sciences, physical and Earth sciences, engineering and architecture, computer and math occupations as well as health-related occupations including healthcare providers and technicians. See the Appendix for specific occupations in each job cluster.

An updated analysis from BLS, accounting for labor market shifts stemming from the coronavirus pandemic, points to strong gains in jobs related to research and development in STEM (including physical, engineering, life sciences and health-related job clusters). Jobs in specific occupations, such as epidemiologist, medical scientists, biochemists and biophysicists, and biological technicians are expected to see strong growth.

In the past, science was a synonym for "knowledge" or "study", in keeping with its Latin origin. A person who conducted scientific research was called a "natural philosopher" or "man of science".[36] In 1834, William Whewell introduced the term scientist in a review of Mary Somerville's book On the Connexion of the Physical Sciences,[37] crediting it to "some ingenious gentleman" (possibly himself).[38]

Science has no single origin. Rather, systematic methods emerged gradually over the course of tens of thousands of years,[39][40] taking different forms around the world, and few details are known about the very earliest developments. Women likely played a central role in prehistoric science,[41] as did religious rituals.[42] Some scholars use the term "protoscience" to label activities in the past that resemble modern science in some but not all features;[43][44][45] however, this label has also been criticized as denigrating,[46] or too suggestive of presentism, thinking about those activities only in relation to modern categories.[47]

The printing press was widely used to publish scholarly arguments, including some that disagreed widely with contemporary ideas of nature.[96] Francis Bacon and Ren Descartes published philosophical arguments in favor of a new type of non-Aristotelian science. Bacon emphasized the importance of experiment over contemplation, questioned the Aristotelian concepts of formal and final cause, promoted the idea that science should study the laws of nature and the improvement of all human life.[97] Descartes emphasized individual thought and argued that mathematics rather than geometry should be used to study nature.[98]

During this time, the declared purpose and value of science became producing wealth and inventions that would improve human lives, in the materialistic sense of having more food, clothing, and other things. In Bacon's words, "the real and legitimate goal of sciences is the endowment of human life with new inventions and riches", and he discouraged scientists from pursuing intangible philosophical or spiritual ideas, which he believed contributed little to human happiness beyond "the fume of subtle, sublime or pleasing [speculation]".[101]

During the nineteenth century, many distinguishing characteristics of contemporary modern science began to take shape. These included the transformation of the life and physical sciences, frequent use of precision instruments, emergence of terms such as "biologist", "physicist", "scientist", increased professionalization of those studying nature, scientists gained cultural authority over many dimensions of society, industrialization of numerous countries, thriving of popular science writings and emergence of science journals.[113] During the late 19th century, psychology emerged as a separate discipline from philosophy when Wilhelm Wundt founded the first laboratory for psychological research in 1879.[114]

Natural science is the study of the physical world. It can be divided into two main branches: life science and physical science. These two branches may be further divided into more specialized disciplines. For example, physical science can be subdivided into physics, chemistry, astronomy, and earth science. Modern natural science is the successor to the natural philosophy that began in Ancient Greece. Galileo, Descartes, Bacon, and Newton debated the benefits of using approaches which were more mathematical and more experimental in a methodical way. Still, philosophical perspectives, conjectures, and presuppositions, often overlooked, remain necessary in natural science.[148] Systematic data collection, including discovery science, succeeded natural history, which emerged in the 16th century by describing and classifying plants, animals, minerals, and so on.[149] Today, "natural history" suggests observational descriptions aimed at popular audiences.[150]

The replication crisis is an ongoing methodological crisis that affects parts of the social and life sciences. In subsequent investigations, the results of many scientific studies are proven to be unrepeatable.[194] The crisis has long-standing roots; the phrase was coined in the early 2010s[195] as part of a growing awareness of the problem. The replication crisis represents an important body of research in metascience, which aims to improve the quality of all scientific research while reducing waste.[196]

An area of study or speculation that masquerades as science in an attempt to claim a legitimacy that it would not otherwise be able to achieve is sometimes referred to as pseudoscience, fringe science, or junk science.[197][198] Physicist Richard Feynman coined the term "cargo cult science" for cases in which researchers believe and at a glance looks like they are doing science, but lack the honesty allowing their results to be rigorously evaluated.[199] Various types of commercial advertising, ranging from hype to fraud, may fall into these categories. Science has been described as "the most important tool" for separating valid claims from invalid ones.[200]

There can also be an element of political or ideological bias on all sides of scientific debates. Sometimes, research may be characterized as "bad science," research that may be well-intended but is incorrect, obsolete, incomplete, or over-simplified expositions of scientific ideas. The term "scientific misconduct" refers to situations such as where researchers have intentionally misrepresented their published data or have purposely given credit for a discovery to the wrong person.[201]

Attitudes towards science are often determined by political opinions and goals. Government, business and advocacy groups have been known to use legal and economic pressure to influence scientific researchers. Many factors can act as facets of the politicization of science such as anti-intellectualism, perceived threats to religious beliefs, and fear for business interests.[262] Politicization of science is usually accomplished when scientific information is presented in a way that emphasizes the uncertainty associated with the scientific evidence.[263] Tactics such as shifting conversation, failing to acknowledge facts, and capitalizing on doubt of scientific consensus have been used to gain more attention for views that have been undermined by scientific evidence.[264] Examples of issues that have involved the politicization of science include the global warming controversy, health effects of pesticides, and health effects of tobacco.[264][265]

The New Jersey Student Learning Standards for Science (NJSLS-S) describe the expectations for what students should know and be able to do as well as promote three-dimensional science instruction across the three science domains (i.e., physical sciences, life science, Earth and space sciences). From the earliest grades, the expectation is that students will engage in learning experiences that enable them to investigate phenomena, design solutions to problems, make sense of evidence to construct arguments, and critique and discuss those arguments (in appropriate ways relative to their grade level).
