Evidence-based practice in the context of "Hierarchy of evidence"

Epidemiology is the study and analysis of the distribution (who, when, and where), patterns and determinants of health and disease conditions in a defined population, and application of this knowledge to prevent diseases.

It is a cornerstone of public health, and shapes policy decisions and evidence-based practice by identifying risk factors for disease and targets for preventive healthcare. Epidemiologists help with study design, collection, and statistical analysis of data, amend interpretation and dissemination of results (including peer review and occasional systematic review). Epidemiology has helped develop methodology used in clinical research, public health studies, and, to a lesser extent, basic research in the biological sciences.

Received Pronunciation (RP) is the accent of British English regarded as the standard one, carrying the highest social prestige, since as late as the beginning of the 20th century. It is also commonly referred to as the Queen's English or King's English. The study of RP is concerned only with matters of pronunciation, while other features of standard British English, such as vocabulary, grammar, and style, are not considered.

Language scholars have long disagreed on RP's exact definition, how geographically neutral it is, how many speakers there are, the nature and classification of its sub-varieties, how appropriate a choice it is as a standard, how the accent has changed over time, and even its name. Furthermore, RP has changed to such a degree over the last century that many of its early 20th-century traditions of transcription and analysis have become outdated or are no longer considered evidence-based by linguists. Standard Southern British English (SSBE) is a label some linguists use for the variety that gradually evolved from RP in the late 20th century and replaced it as the commonplace standard variety of Southern England, while others now simply use SSBE and RP as synonyms. Still, the older traditions of RP analysis continue to be commonly taught and used, for instance in language education and comparative linguistics, and RP remains a popular umbrella term in British society.

Occupational therapists (OTs) are health care professionals specializing in occupational therapy and occupational science. OTs and occupational therapy assistants (OTAs) use scientific bases and a holistic perspective to promote a person's ability to fulfill their daily routines and roles. OTs have training in the physical, psychological, and social aspects of human functioning deriving from an education grounded in anatomical and physiological concepts, and psychological perspectives. They enable individuals across the lifespan by optimizing their abilities to perform activities that are meaningful to them ("occupations"). Human occupations include activities of daily living, work/vocation, play, education, leisure, rest and sleep, and social participation.

OTs work in a variety of fields, including pediatrics, orthopedics, neurology, low vision therapy, pelvic floor therapy, hand therapy, physical rehabilitation, mental health, assistive technology, oncological rehabilitation, and geriatrics. OTs are employed in healthcare settings such as hospitals, nursing homes, residential care facilities, home health agencies, outpatient rehabilitation centers, etc. OTs are also employed by school systems, and as consultants by businesses to address employee work-related safety and productivity. Many OTs are also self-employed and own independent practices. In the United States, OTs are also employed as commissioned officers in the Army, Navy and Air force branches of the military. In the US Army, OTs are part of the Army Medical Specialist Corps. OTs are also a part of the United States Public Health Service Commissioned Corps, one of eight uniformed services of the United States.

Evidence-based education (EBE) is the principle that education practices should be based on the best available scientific evidence, with randomised trials as the gold standard of evidence, rather than tradition, personal judgement, or other influences. Evidence-based education is related to evidence-based teaching, evidence-based learning, and school effectiveness research.

The evidence-based education movement has its roots in the larger movement towards evidence-based practices, and has been the subject of considerable debate since the late 1990s. However, research published in 2020 showed that belief is high amongst educators in teaching techniques such as matching instruction to a few supposed learning styles and the cone of learning despite absence of empirical evidence.

Writing education in the United States at a national scale using methods other than direct teacher–student tutorial were first implemented in the 19th century. The positive association between students' development of the ability to use writing to refine and synthesize their thinking and their performance in other disciplines is well-documented.

A review of evidence-based practice studies emphasizes that instruction in writing should include: substantial and varied kinds of writing with supportive feedback, explicit teaching of skills and strategies, contemporary composing technologies, and opportunities to use writing as a means to develop knowledge of content. Another meta-analysis has confirmed that these benefits extend beyond English Language Arts classrooms and across the disciplines, finding evidence that science, social studies, and mathematics teachers who use writing-to-learn strategies can "reasonably expect" gains in "students' comprehension and application of content knowledge." Teachers' own professional preparation to teach writing, their personal beliefs about writing, and local and national policies regarding curriculum and instruction have been shown to influence how students learn and develop as writers.
