Sand Table
A sand table uses constrained sand for modelling or educational purposes. The original version of a sand table may be the ''abax'' used by early Greek students. In the modern era, one common use for a sand table is to make terrain models for military planning and wargaming. Abax An ''abax'' was a table covered with sand commonly used by students, particularly in Greece, to perform studies such as writing, geometry, and calculations. The ''abax'' was the predecessor to the abacus. Objects, such as stones, were added for counting and then columns for place-valued arithmetic. The demarcation between an ''abax'' and an abacus seems to be poorly defined in history; moreover, modern definitions of the word ''abacus'' universally describe it as a frame with rods and beads and, in general, do not include the definition of "sand table". The sand table may well have been the predecessor to some board games. ("The word abax, or abacus, is used both for the reckoning-board with its counte ...

Cartography
Cartography (; from , 'papyrus, sheet of paper, map'; and , 'write') is the study and practice of making and using maps. Combining science, aesthetics and technique, cartography builds on the premise that reality (or an imagined reality) can be modeled in ways that communicate spatial information effectively. The fundamental objectives of traditional cartography are to: * Set the map's agenda and select traits of the object to be mapped. This is the concern of map editing. Traits may be physical, such as roads or land masses, or may be abstract, such as toponyms or political boundaries. * Represent the terrain of the mapped object on flat media. This is the concern of map projections. * Eliminate the mapped object's characteristics that are irrelevant to the map's purpose. This is the concern of Cartographic generalization, generalization. * Reduce the complexity of the characteristics that will be mapped. This is also the concern of generalization. * Orchestrate the elements ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mathematical Tools
Mathematics is a field of study that discovers and organizes methods, theories and theorems that are developed and proved for the needs of empirical sciences and mathematics itself. There are many areas of mathematics, which include number theory (the study of numbers), algebra (the study of formulas and related structures), geometry (the study of shapes and spaces that contain them), analysis (the study of continuous changes), and set theory (presently used as a foundation for all mathematics). Mathematics involves the description and manipulation of abstract objects that consist of either abstractions from nature orin modern mathematicspurely abstract entities that are stipulated to have certain properties, called axioms. Mathematics uses pure reason to prove properties of objects, a ''proof'' consisting of a succession of applications of deductive rules to already established results. These results include previously proved theorems, axioms, andin case of abstracti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Mathematics
The history of mathematics deals with the origin of discoveries in mathematics and the History of mathematical notation, mathematical methods and notation of the past. Before the modern age and the worldwide spread of knowledge, written examples of new mathematical developments have come to light only in a few locales. From 3000 BC the Mesopotamian states of Sumer, Akkad (region), Akkad and Assyria, followed closely by Ancient Egypt and the Levantine state of Ebla began using arithmetic, algebra and geometry for purposes of taxation, commerce, trade and also in the field of astronomy to record time and formulate calendars. The earliest mathematical texts available are from Mesopotamia and Ancient Egypt, Egypt – ''Plimpton 322'' (Babylonian mathematics, Babylonian – 1900 BC),Friberg, J. (1981). "Methods and traditions of Babylonian mathematics. Plimpton 322, Pythagorean triples, and the Babylonian triangle parameter equations", ''Historia Mathematica'', 8, pp. 277–318. the ' ...

History Of Education
The history of education, like other history, extends at least as far back as the first written records recovered from ancient civilizations. Historical studies have included virtually every nation. The earliest known formal school was developed in Egypt's Middle Kingdom under the direction of Kheti, treasurer to Mentuhotep II (2061–2010 BC). In ancient India, education was mainly imparted through the Sanskrit and Vedic learning, Vedic and Buddhist learning system, while the first education system in ancient China was created in Xia dynasty (2076–1600 BC). In the city-states of ancient Greece, most education was private, except in Sparta. For example, in Athens, during the 5th and 4th century BC, aside from two years military training, the state played little part in schooling. The first schools in Ancient Rome arose by the middle of the 4th century BC. In Europe, during the Early Middle Ages, the monasteries of the Roman Catholic Church were the centers of education and li ...

History Of Computing
The history of computing is longer than the history of computing hardware and modern computing technology and includes the history of methods intended for pen and paper or for chalk and slate, with or without the aid of tables. Concrete devices Digital computing is intimately tied to the representation of number A number is a mathematical object used to count, measure, and label. The most basic examples are the natural numbers 1, 2, 3, 4, and so forth. Numbers can be represented in language with number words. More universally, individual numbers can ...s. But long before abstractions like ''the number'' arose, there were mathematical concepts to serve the purposes of civilization. These concepts are implicit in concrete practices such as: *''Bijection, One-to-one correspondence'', a rule to counting, count ''how many'' items, e.g. on a tally stick, eventually abstracted into ''numbers''. *''Comparison to a standard'', a method for assuming ''reproducibility'' in a measure ...

Writing Media
A writing material, also called a writing medium, is a surface that can be written on with suitable instruments, or used for symbolic or representational drawings. Building materials on which writings or drawings are produced are not included. The gross characterization of writing materials is by the material constituting the writing surface (for example, paper) and the number, size, usage, and storage configuration of multiple surfaces (for example, paper sheets) into a single object. Early media Because drawing preceded writing, the first remains of writing materials are the stone walls of the caves on which cave paintings were drawn. Another precursor was tally sticks used to record the count of objects. Writing seems to have become more widespread with the invention of papyrus in Egypt. Parchment, using sheepskins left after the wool was removed for cloth, was sometimes cheaper than papyrus, which had to be imported from outside of Egypt. To save money on expensive papyr ...

Edward Burnett Tylor
Sir Edward Burnett Tylor (2 October 18322 January 1917) was an English anthropologist, and professor of anthropology. Tylor's ideas typify 19th-century cultural evolutionism. In his works '' Primitive Culture'' (1871) and ''Anthropology'' (1881), he defined the context of the scientific study of anthropology, based on the evolutionary theories of Charles Lyell. He believed that there was a functional basis for the development of society and religion, which he determined was universal. Tylor maintained that all societies passed through three basic stages of development: from savagery, through barbarism to civilization. Tylor is a founding figure of the science of social anthropology, and his scholarly works helped to build the discipline of anthropology in the nineteenth century.Paul Bohannan, ''Social Anthropology'' (New York: Holt, Rinehart & Winston, 1969) He believed that "research into the history and prehistory of man ..could be used as a basis for the reform of Bri ...

Sand Art And Play
Sand is a granular material composed of finely divided mineral particles. Sand has various compositions but is usually defined by its grain size. Sand grains are smaller than gravel and coarser than silt. Sand can also refer to a soil texture, textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass. The composition of sand varies, depending on the local rock sources and conditions, but the most common constituent of sand in inland continental settings and non-tropical coastal settings is silica (silicon dioxide, or SiO2), usually in the form of quartz. Calcium carbonate is the second most common type of sand. One such example of this is aragonite, which has been created over the past 500million years by various forms of life, such as coral and shellfish. It is the primary form of sand apparent in areas where reefs have dominated the ecosystem for millions of years, as in the Caribbean. Somewhat more rarely, sand may be c ...

Special Education
Special education (also known as special-needs education, aided education, alternative provision, exceptional student education, special ed., SDC, and SPED) is the practice of educating students in a way that accommodates their individual differences, Disability, disabilities, and special needs. This involves the individually planned and systematically monitored arrangement of teaching procedures, adapted equipment and materials, and accessible settings. These interventions are designed to help individuals with special needs achieve a higher level of personal Self-sustainability, self-sufficiency and success in school and in their community, which may not be available if the student were only given access to a Traditional education, typical classroom education. Special education aims to provide accommodated education for disabled students such as learning disability, learning disabilities, learning difficulties (such as dyslexia), communication disorders, emotional and behavi ...

Educational Stages
Educational stages are subdivisions of formal learning, typically covering early childhood education, primary education, secondary education and tertiary education. The United Nations Educational, Scientific and Cultural Organization (UNESCO) recognizes nine levels of education in its International Standard Classification of Education (ISCED) system (from Level 0 (pre-primary education) through Level 8 (doctoral)). UNESCO's International Bureau of Education maintains a database of country-specific education systems and their stages. Some countries divide levels of study into grades or Form (education), forms for school children in the same year. Organization Education during childhood and early adulthood is typically provided through either a two- or three-stage system of childhood school, followed by additional stages of higher education or vocational education for those who continue their formal education: *Early childhood education at preschool, nursery school, or kindergarten ...
