Exam

Exam is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Exam rather than just read about it. In short: An examination (exam or evaluation), or test, is an educational assessment intended to measure a test-taker's knowledge, skill, aptitude, physical fitness, or classification in many other topics (e.g., beliefs). A test may be administered verbally, on paper, on a computer, or in a predetermined area that requires a test taker to demonstrate or perform a set of skills.

Key takeaways

  • Exam belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Exam to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Exam from memory before moving on to harder problems.

Reference excerpt

An examination (exam or evaluation), or test, is an educational assessment intended to measure a test-taker's knowledge, skill, aptitude, physical fitness, or classification in many other topics (e.g., beliefs). A test may be administered verbally, on paper, on a computer, or in a predetermined area that requires a test taker to demonstrate or perform a set of skills. Tests vary in style, rigor and requirements. There is no general consensus or invariable standard for test formats and difficulty. Often, the format and difficulty of the test is dependent upon the educational philosophy of the instructor, subject matter, class size, policy of the educational institution, and requirements of accreditation or governing bodies. A test may be administered formally or informally. An example of an informal test is a reading test administered by a parent to a child. A formal test might be a final examination administered by a teacher in a classroom or an IQ test administered by a psychologist in a clinic. Formal testing often results in a grade or a test score. A test score may be interpreted with regard to a norm or criterion, or occasionally both. The norm may be established independently, or by statistical analysis of a large number of participants. A test may be developed and administered by an instructor, a clinician, a governing body, or a test provider. In some instances, the developer of the test may not be directly responsible for its administration. For example, in the United States, Educational Testing Service (ETS), a nonprofit educational testing and assessment organization, develops standardized tests such as the SAT but may not directly be involved in the administration or proctoring of these tests.

History

Oral and informal examinations Informal, unofficial, and non-standardized tests and testing systems have existed throughout history. For example, tests of skill such as archery contests have existed in China since the Zhou dynasty (or, more mythologically, Yao). Oral exams were administered in various parts of the world including ancient China and Europe. A precursor to the later Chinese imperial examinations was in place since the Han dynasty, during which the Confucian characteristic of the examinations was determined. However these examinations did not offer an official avenue to government appointment, the majority of which were filled through recommendations based on qualities such as social status, morals, and ability.

China Standardized written examinations were first implemented in China. They were commonly known as the imperial examinations (keju). The bureaucratic imperial examinations as a concept has its origins in the year 605 during the short lived Sui dynasty. Its successor, the Tang dynasty, implemented imperial examinations on a relatively small scale until the examination system was extensively expanded during the reign of Wu Zetian. Included in the expanded examination system was a military exam that tested physical ability, but the military exam never had a significant impact on the Chinese officer corps and military degrees were seen as inferior to their civil counterpart. The exact nature of Wu's influence on the examination system is still a matter of scholarly debate. During the Song dynasty the emperors expanded both examinations and the government school system, in part to counter the influence of hereditary nobility, increasing the number of degree holders to more than five times that of the Tang. From the Song dynasty onward, the examinations played the primary role in selecting scholar-officials, who formed the literati elite of society. However the examinations co-existed with other forms of recruitment such as direct appointments for the ruling family, nominations, quotas, clerical promotions, sale of official titles, and special procedures for eunuchs. The regular higher level degree examination cycle was decreed in 1067 to be 3 years but this triennial cycle only existed in nominal terms. In practice both before and after this, the examinations were irregularly implemented for significant periods of time: thus, the calculated statistical averages for the number of degrees conferred annually should be understood in this context. The jinshi exams were not a yearly event and should not be considered so; the annual average figures are a necessary artifact of quantitative analysis. The operations of the examination system were part of the imperial record keeping system, and the date of receiving the jinshi degree is often a key biographical datum: sometimes the date of achieving jinshi is the only firm date known for even some of the most historically prominent persons in Chinese history. A brief interruption to the examinations occurred at the beginning of the Mongol Yuan dynasty in the 13th century, but was later brought back with regional quotas which favored the Mongols and disadvantaged Southern Chinese. During the Ming and Qing dynasties, the system contributed to the narrow and focused nature of intellectual life and enhanced the autocratic power of the emperor. The system continued with some modifications until its abolition in 1905 during the last years of the Qing dynasty. The modern examination system for selecting civil servants also indirectly evolved from the imperial one.

Spread

Japan Japan implemented the examination system for 200 years during the Heian period (794–1185). Like the Chinese examinations, the curriculum revolved around the Confucian canon. However, unlike in China, it was only ever applied to the minor nobility and so gradually faded away under the hereditary system during the Samurai era.

Korea

The examination system was established in Korea in 958 under the reign of Gwangjong of Goryeo. Any free man (not Nobi) was able to take the examinations. By the Joseon period, high offices were closed to aristocrats who had not passed the exams. The examination system continued until 1894 when it was abolished by the Gabo Reform. As in China, the content of the examinations focused on the Confucian canon and ensured a loyal scholar bureaucrat class which upheld the throne.

Vietnam The Confucian examination system in Vietnam was established in 1075 under the Lý dynasty Emperor Lý Nhân Tông and lasted until the Nguyễn dynasty Emperor Khải Định (1919). There were only three levels of examinations in Vietnam: interprovincial, pre-court, and court.

Worked examples

Example 1 — a first encounter with Exam

Start with the simplest possible case. Write down what Exam claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Exam before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Exam ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Exam

In research
Exam appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Exam in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Exam is common in secondary-school and first-year university syllabi. It links to neighbouring topics Examinations, so understanding it makes those chapters shorter.
In everyday life
Look for Exam outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
