Differentiated Instruction
Differentiated instruction and assessment, also known as differentiated learning or, in education, simply, differentiation, is a framework or philosophy for effective teaching that involves providing all students within their diverse classroom community of learners a range of different avenues for understanding new information (often in the same classroom) in terms of: acquiring content; processing, constructing, or making sense of ideas; and developing teaching materials and assessment measures so that all students within a classroom can learn effectively, regardless of differences in their ability.Differentiated instruction means using different tools, content, and due process in order to successfully reach all individuals. Differentiated instruction, according to Carol Ann Tomlinson, is the process of "ensuring that what a student learns, how he or she learns it, and how the student demonstrates what he or she has learned is a match for that student's readiness level, interests, ...

Cellular Differentiation
Cellular differentiation is the process in which a stem cell alters from one type to a differentiated one. Usually, the cell changes to a more specialized type. Differentiation happens multiple times during the development of a multicellular organism as it changes from a simple zygote to a complex system of tissues and cell types. Differentiation continues in adulthood as adult stem cells divide and create fully differentiated daughter cells during tissue repair and during normal cell turnover. Some differentiation occurs in response to antigen exposure. Differentiation dramatically changes a cell's size, shape, membrane potential, metabolic activity, and responsiveness to signals. These changes are largely due to highly controlled modifications in gene expression and are the study of epigenetics. With a few exceptions, cellular differentiation almost never involves a change in the DNA sequence itself. Although metabolic composition does get altered quite dramatically ...

Differentiation (sociology)
In system theory. "differentiation" is the increase of subsystems in a modern society to increase the complexity of a society. Each subsystem can make different connections with other subsystems, and this leads to more variation within the system in order to respond to variation in the environment. Differentiation that leads to more variation allows for better responses to the environment, and also for faster evolution (or perhaps sociocultural evolution), which is defined sociologically as a process of selection from variation; the more differentiation (and thus variation) that is available, the better the selection. Introduction Talcott Parsons was the first major theorist to develop a theory of society consisting of functionally defined sub-system, which emerges from an evolutionary point of view through a cybernetic process of differentiation. Niklas Luhmann, who studied under Talcott Parsons, took the latter's model and changed it in significant ways. Parsons regarded ...

Differentiation (economics)
In economics and marketing, product differentiation (or simply differentiation) is the process of distinguishing a product or service from others to make it more attractive to a particular target market. This involves differentiating it from competitors' products as well as from a firm's other products. The concept was proposed by Edward Chamberlin in his 1933 book, ''The Theory of Monopolistic Competition''. Rationale Firms have different resource endowments that enable them to construct specific competitive advantages over competitors. Resource endowments allow firms to be different, which reduces competition and makes it possible to reach new segments of the market. Thus, differentiation is the process of distinguishing the differences of a product or offering from others, to make it more attractive to a particular target market. Although research in a niche market may result in changing a product in order to improve differentiation, the changes themselves are not diffe ...

Developmental Biology
Developmental biology is the study of the process by which animals and plants grow and develop. Developmental biology also encompasses the biology of regeneration, asexual reproduction, metamorphosis, and the growth and differentiation of stem cells in the adult organism. Perspectives The main processes involved in the embryonic development of animals are: tissue patterning (via regional specification and patterned cell differentiation); tissue growth; and tissue morphogenesis. * Regional specification refers to the processes that create the spatial patterns in a ball or sheet of initially similar cells. This generally involves the action of cytoplasmic determinants, located within parts of the fertilized egg, and of inductive signals emitted from signaling centers in the embryo. The early stages of regional specification do not generate functional differentiated cells, but cell populations committed to developing to a specific region or part of the organism. These are ...

Igneous Differentiation
In geology, igneous differentiation, or magmatic differentiation, is an umbrella term for the various processes by which magmas undergo bulk chemical change during the partial melting process, cooling, emplacement, or eruption. The sequence of (usually increasingly silicic) magmas produced by igneous differentiation is known as a magma series. Definitions Primary melts When a rock melts to form a liquid, the liquid is known as a ''primary melt''. Primary melts have not undergone any differentiation and represent the starting composition of a magma. In nature, primary melts are rarely seen. Some leucosomes of migmatites are examples of primary melts. Primary melts derived from the mantle are especially important and are known as ''primitive melts'' or primitive magmas. By finding the primitive magma composition of a magma series, it is possible to model the composition of the rock from which a melt was formed, which is important because we have little direct evidence of the ...

Planetary Differentiation
In planetary science, planetary differentiation is the process by which the chemical elements of a planetary body accumulate in different areas of that body, due to their physical or chemical behavior (e.g. density and chemical affinities). The process of planetary differentiation is mediated by partial melting with heat from radioactive isotope decay and planetary accretion. Planetary differentiation has occurred on planets, dwarf planets, the asteroid 4 Vesta, and natural satellites (such as the Moon). Physical differentiation Gravitational separation High-density materials tend to sink through lighter materials. This tendency is affected by the relative structural strengths, but such strength is reduced at temperatures where both materials are plastic or molten. Iron, the most common element that is likely to form a very dense molten metal phase, tends to congregate towards planetary interiors. With it, many siderophile elements (i.e. materials that readily alloy with iron) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Differentiation (linguistics)
Differentiation in semantics is defined by Löbner (2002) as a meaning shift reached by "adding concepts to the original concepts". His example is ''James Joyce is hard to understand'', where ''understand'' is differentiated from "perceiving the meaning" to "interpret the text meaning". A related meaning shift is metonymy Metonymy () is a figure of speech in which a concept is referred to by the name of something closely associated with that thing or concept. Etymology The words ''metonymy'' and ''metonym'' come from grc, μετωνυμία, 'a change of name' ..., where one builds a new concept out of an element of the original concept. In the example mentioned, ''James Joyce'' most likely refers to "the work of James Joyce" and not to the author – a metonymical shift. If the name were to refer to the man, ''understand'' would be differently differentiated, perhaps one would read it as "interpret the speech articulation" or "comprehend the actions" of the person James Jo ...

Differentiation (mathematics)
In mathematics, the derivative of a function of a real variable measures the sensitivity to change of the function value (output value) with respect to a change in its argument (input value). Derivatives are a fundamental tool of calculus. For example, the derivative of the position of a moving object with respect to time is the object's velocity: this measures how quickly the position of the object changes when time advances. The derivative of a function of a single variable at a chosen input value, when it exists, is the slope of the tangent line to the graph of the function at that point. The tangent line is the best linear approximation of the function near that input value. For this reason, the derivative is often described as the "instantaneous rate of change", the ratio of the instantaneous change in the dependent variable to that of the independent variable. Derivatives can be generalized to functions of several real variables. In this generalization, the derivat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Differentiated Security
Differentiated security is a form of computer security that deploys a range of different security policies and mechanisms according to the identity and context of a user or transaction. This makes it much more difficult to scale or replicate attacks, since each cluster/individual has a different security profile and there should be no common weaknesses. One way of achieving this is by subdividing the population into small differentiated clusters. At the extreme, each individual belongs to a different class. See also * Differentiated service (design pattern) *Separation of protection and security In computer sciences, the separation of protection and security is a design choice. Wulf et al. identified protection as a mechanism and security as a policy,Wulf 74 pp.337-345 therefore making the protection-security distinction a particular case ...

Differentiated Service
{{for, the network traffic classification system, Differentiated services Differentiated service is a design pattern for business services and software, in which the service varies automatically according to the identity of the consumer and/or the context in which the service is used. Sometimes known as smart service or context-aware service. Concept Differentiated service is extensively covered in a few narrow technical areas, such as telecoms networks and internet (see Differentiated services). It is also mentioned in some marketing sources, with reference to customer segmentation. But the general principle of service differentiation extends far beyond these domains, and it is one of the mechanisms for implementing flexibility in a service-oriented architecture (SOA). Various dimensions of the service can be differentiated, including: *Information quality. For example, an information service providing stock prices may offer real-time prices to selected users, and 15-minute-dela ...
