Developing Mathematical Abilities for Children

Developing Mathematical Abilities for Children The mathematical development foundation was established in the earliest years. Mathematics learning had built on curiosity and enthusiasm for children to grow naturally. Mathematics at this age, is suitably connected to a child’s world, is more than â€Å"getting ready† for school or accelerating them into elementary mathematics. Appropriate mathematical skills challenge young children to explore ideas related to patterns, shapes, numbers, and space with increasing complexity. The child’s cognitive development is how the concentration works and how the children learn, aim and comprehend. As children develop cognitive from pre-lingual and pre-symbolic stage to the use of language and symbols to operate concepts. The ability related to later mathematics learning are also developing. The abilities for mathematics cognitive learning are memory, language skills and the ability to male mental pictures of numbers and space. Young children begin to use their memory when co-operating with others and recall the experiences. Infants will respond to familiar faces and to music. Children begin to notice environment print and they begin to understand the role of letters and numbers as abstract symbols for familiar things.

Young children begin to use their memory when co-operating with others and recall the experiences. Infants will respond to familiar faces and to music. Children begin to notice environment print and they begin to understand the role of letters and numbers as abstract symbols for familiar things. Pattern making it is significant as it enables children to identify simple repeated ideas. It is a good basis for finding patterns in numbers later on. Sorting will help children’s understanding of numbers, they should have opportunities to sort as many different materials as possible and in many different ways as they can. Counting and ordering children will need to be come familiar with the number system, they will need to do this through counting and ordering numbers and group of numbers with the same criteria. Recording they will start to record numbers and patterns. They have found out in simple ways, through pictures and simple charts and tallies. When I was observing children there was a child that knew the numbers and knew how to make 3 colours the same. This child is very intelligent, last day we were playing with blocks and I told him to tell me how many reds there are and he told me that there are 10 in all. Then I told him to put 4 block together that are the same colour and he did them without any help. In maths the boy is at a higher level, he knows how to count and to join 4 blocks together I was playing with a boy and we were saying numbers and I told him to count the clothes that there are suspended and he started to count but he didn’t knew the numbers well. He begin to count but he forgot what numbers comes after 1 and he had some problem to remember them so I tried to help him by saying him the beginning of the numbers but he couldnt remember the number that comes after 1. This child needs help in numbers, he need someone to teach him the numbers at home. I think that their parents are not helping him and teaching him the numbers. His level is low and he needs to improve more. The children built their confidence when they have someone who understands them and who play with them. They be confident with people that they have attachment with. When children know things like numbers they feel more confident of saying them. If they are confident their self- esteem will be more high. For children to be fruitful in working with others, and in explanation their own sympathies, they must develop the mathematical language vital to help them express what they believe. Conversation amongst themselves and with a teacher, offers children with chances for social message, and for shared understandings to be exchanging and developed. To do this children need to have self-assurance and don’t be shy of saying the answers or asking a question. If they don’t understand they can’t learn maths well so they need to be confident and ask. Yesterday I was doing an activity with 2 children that are the same age. They are different from each other because one is very confident and likes to do the activities and she is very motivated of doing them. Her self esteem is very high and she is very confident. The other child is very shy and he don’t like to interact with others. He don’t like to do activities because he knows that Im going to ask him questions for example which color he like most so he need to built some confidence with himself and with others because his self-esteem is very low. He need to communicate more with others even at home his parents need to interact more with him. As with all others areas of learning one will need to build children’s confidence when working on mathematical ideas. From an early age , children should be presented with positive and fun methods of working with mathematical tasks in ways that engage all learners. Adults should take care to ensure that tasks are introduced in a way that stimulates children so that they do think of mathematics as difficult. Occasionally concepts may be difficult to grasp, and children will find new ideas challenging. They should be given plenty of opportunities to use games, investigations and other forms of mathematics, which will develop their skills while also encouraging them to be independent. Last day we were playing, and in the class we have a number line. I was playing with Christian and I asked him to count the numbers. He was very shy at the beginning because he don’t believe in himself and he don’t have confidence with others. Then I helped him by praising him and told him that he is able to count them and I knew that he know them so he began to count them. He needed some support and courage to built confidence and to feel comfortable talking to me. Im going to talk about the theories that are involved in mathematical development. I’m going to talk about Piaget and his conservation of numbers according to his constructivist theory. Constructivism, first developed by Piaget, views learning of mathematics as the building of meaning and understanding based on the modeling of reality, the examination of pattern, and the gaining of a mathematical nature. Though I have chosen conservation in mathematics as the test case the account Piaget provided is expected to apply more usually to his entire composition, and I believe is further genuine by changes in his thought he also draw upon other examples to make his case. He make no effort to define the different stages of Piagetian development but make position to them when necessary; that wasnt his focus. More, he use Skinner as the exemplar of behaviorism even though there are other varieties. The reasons for doing so rest with his supremacy among instructors of all punishments and the potential benefits to justifying the wide-spread mistake of his work, too. Language and hearing processing shortfalls affect ability to learn language and math concepts and solve problems. Students may have amenable or communicative language problems that can considerably affect their learning and ability to express what they do not comprehend or show how they solved problems. They can help them by teaching them those things: Partner with Teachers to Manage Language and Auditory Processing Deficits. Use Hands-on Materials to Improve Your Childs Math Comprehension Re-Write Word Problems to Enhance Auditory Comprehension Provide Step-by-Step Models of Problem Solving We were doing an activity about maths and I was explaining them sum and what they need to do some of the children couldnt understand the concept of the sum so I needed to explain it again and more in detail. If I didn’t explained it again and more in detailed they wouldnt understand and learn the sum. When I was doing the activity some of the children didn’t understood the vocabulary because was a little bit hard for them so I asked them where they didn’t understood and I explained it better.

The Character of Hester Prynne in The Scarlet Letter Essay -- Papers N

The Character of Hester Prynne in The Scarlet Letter Hester Prynne, a character within The Scarlet Letter, is a prime example of Hawthorne's common transformation of individuals within his books. These mutations involve the qualities and attributes of her physical appearance, feminine emotions, and reputation among the townspeople. Throughout the novel, the mentioned elements of Hester's character develop and change several times, providing the reader with better understanding of the influence that the scarlet letter and other characters have on her. In the beginning of the novel, the reader is presented with a physical appearance of Hester that is pleasing to the visual eye. It is Hawthorne describes his heroine of the book by writing that "She had dark and abundant hair†¦face†¦beautiful†¦features and richness of complexion†¦deep black eyes" (51). Over time, these attributes faded and the "attractiveness of her person had undergone†¦change†¦sad transformation†¦luxuriant hair†¦cut off†¦hidden†¦some attribute had departed from her, the permanence of which had been essential to keep her ...

Justice in Antigone

Antiquity and the 19th Century (Ulfers) William Rauscher Thursday, 9:30AM Justice in Antigone In Sophocles’ Antigone, two notions of ‘justice’ are presented, which conflict with each other. Creon’s form of justice rewards the loyal Eteocles and punishes the traitor Polyneices, by refusing to give Polyneices proper burial rites. This form of justice directly conflicts with Antigone’s idea of justice, which doesn’t differentiate between the â€Å"wicked† and the â€Å"just. † These two conflicting thoughts on justice illustrate two classic philosophies.Creon represents a Paramenidean view of justice, while Antigone represents a Heraclitean view of justice. Paramenidean thought splits the world into two systems, where â€Å"Being† is primary and â€Å"Becoming† is secondary (Ulfers, Lecture). To Paramenides, â€Å"Being† is associated with the idea of â€Å"oneness† and â€Å"timelessness,† while a ny â€Å"Becoming† or process is an illusion produced by the senses. This dualistic worldview simplifies everyday occurrences and thoughts into opposites, which are unchangeable. In contrast, Heraclitean thought presents â€Å"Becoming† as primary, while â€Å"Being† is secondary (Ulfers, Lecture).Heraclitus regards change and temporality as ultimate in a perpetual process of â€Å"Becoming. † Heraclitus goes on to argue that opposites are simultaneously present in a state known as chiasmic unity. Chiasmic unity constitutes a paradoxical unity of opposites, which binds opposites together and keeps them apart. Heraclitean thought favors the logic of â€Å"both/and,† which violates the Paramenidean logic of â€Å"either/or. † Antigone presents a Heraclitean view of justice in a conversation with her sister Ismene abut Creon’s proclamation that their brother, Polyneices, will ot receive proper burial rites. Antigone determines that Creon has no authority to dictate burial rites: â€Å"It is not for him [Creon] to keep me from my own† (Sophocles, 163). By choosing to defy Creon’s decree, Antigone accepts her fate as â€Å"a criminal-but a religious one,† revealing that she wants to make her act of defiance a public example. Antigone does not fear Creon’s threat of punishment because she follows a different form of justice based on a higher religious authority.Religion functions in a chiasmic structure, where the opposite values of â€Å"wicked† and â€Å"just,† lose their oppositional aspects (Ulfers, Lecture). Antigone’s commitment to a Heraclitean view of justice allows her to defy the sovereign, yet keep her honor: â€Å"No suffering of mine will be enough to make me die ignobly† (Sophocles 165). In contrast, Ismene chooses to follow Creon’s interpretation of justice because he is the current ruling power, whose authority is unquestioned. She is not a ble to see past the â€Å"either/or† logic Creon has imposed on his people.As a wiser, older sister, Ismene warns Antigone about disobeying Creon, pleading with Antigone to come to her senses: â€Å"†¦and see how miserable our end shall be if in the teeth of law we shall transgress against the sovereign’s decree and power†¦Extravagant action is not sensible† (Sophocles, 163). Ismene determines that Antigone’s intended action is flawed because it goes beyond the simplicity of following the sovereign’s law. Despite these warnings, Antigone is compelled to defy Creon’s proclamation as a result of her Heraclitean view of justice.Creon confronts Antigone for defying his decree. In contrast to Antigone, Creon represents the Paramenidean view of justice, which is based on an oppositional order of wicked and just, punishment and reward (Ulfers, Lecture). Creon extends these distinctions to the realm of the dead: â€Å"My enemy is still my enemy even in death† (Sophocles 181). Creon believes that by extending the intolerance of treachery into death’s realm, he will set an example that will dissuade any future uprisings against his rule.Antigone shows no remorse for her actions, believing that Creon’s rule does not extend to the realm of the dead: â€Å"†¦it was not Zeus that made the proclamation; nor did Justice, which lives with those below, enact such laws as that, for mankind. I did not believe your proclamation had such power to enable one who will someday die to override God’s ordinances† (Sophocles 178). Antigone disagrees with Creon, since death is inevitable and is neither considered a punishment nor a reward. In this sense, judgment is suspended in the realm of death.She feels that the mortal Creon cannot make a proclamation that governs the realm of the dead. Antigone embodies a â€Å"law† that revolves around the chiasmic unity of the opposite values of honor and dishonor attributed to Etocles and Polyneices, respectively (Ulfers, Lecture). She will not give allegiance to the temporal rules of Creon, since she will be in conflict with the higher authority of the gods regarding the realm of death: â€Å"The god of death demands these rites for both† (Sophocles 181).As a result of Antigone’s public display of disobedience toward Creon’s rule, Creon believes that he is forced to fulfill the justified punishment of death on Antigone. In order to uphold his authority as a good ruler, he feels that he has to rule with intolerance toward disobedience: â€Å"The man the city set up in authority must be obeyed in small things and in just but also in their opposites† (Sophocles, 187). In Creon’s mind, creating a victorious rule means inflexible justice, order, and discipline.This unchanging mentality of a strict separation of being either loyal or disloyal and receiving either reward or punishment represents a Pa ramenidean view of justice. His form of justice is devoid of leniency and mercy, only seeing his own perspective on justice. Creon finally realizes the true â€Å"injustice† of his law only after the tragic deaths of his son, wife, and Antigone: â€Å"The mistakes of a blinded man are themselves rigid and laden with death† (Sophocles, 209).His inflexible decrees blinded him from true justice by locking him into a rigid Paramenidean view of the world. After facing unparalleled tragedies, he ultimately has gained insight into Antigone’s â€Å"justice. † Creon has switched from the Paramenidean separation of opposites to the chiasmic unity of opposites: â€Å"Everything in my hands is crossed† (Sophocles, 212). Creon is now able to comprehend that not everything can be categorized into separate distinctions to be judged, seeming to accept the Heraclitean view of justice.Creon sees the error in his notion of justice, but he is too late to prevent the t ragedy that befalls him. His absolute power of ruling combined with his pride and arrogance leads him to be blinded to Antigone’s beliefs. At the end of the play, Creon gains â€Å"wisdom† from his â€Å"unwelcome fate† realizing that he â€Å"[should] have kept the old accepted laws† (Sophocles 204, 212). This realization bestows upon him the knowledge to rule in favor of the â€Å"both/and† Heraclitean view of justice, rather than the â€Å"either/or† Paramenidean view of justice that he once followed.

Anglo

Anglo Although, it now became a commonplace practice among particularly ‘progressive’ social activists to blame Western civilization on account of its environmental unfriendliness, the objective analysis points out to the fact that it is namely in Western societies, where people have traditionally been concerned with trying to preserve nature. The soundness of this suggestion can be well illustrated even today.Advertising We will write a custom research paper sample on Anglo-Germanic Writers’ Influence on Popular Environmental Thinking specifically for you for only $16.05 $11/page Learn More For example; whereas, in Nigeria it is being considered absolutely normal by the residents of country’s even biggest cities to dump garbage onto the street, right in front of their shabby houses1, in such Western countries as Britain, Sweden and Germany, one may very well end up facing administrative charges for even as little as throwing a cigarette butt anywhere else but into specially designed garbage bins. And, the reason why, as compared to the people from Third World countries, Westerners appear to grow ever more environmentally aware is simple. As history indicates, the more a particular society is being affected by scientific progress, the less its members require natural resources to sustain their physical existence, which in its turn creates objective preconditions for them to consider adopting friendly stance towards the nature. In other words, the notions of environmental friendliness and scientific progress are very much.2 This is precisely the reason why it is specifically Anglo-Saxon societies, which have traditionally been considered the most technologically advanced, that continue to feature world’s highest environmental standards. In our paper, we will aim to substantiate the full soundness of this suggestion by exploring how creative writings and visual artworks from Anglo/Germanic authors, concerned w ith popularizing the objective essence of natural laws, contributed towards increasing the extent of public’s environmental awareness in 19th and 20th centuries. When we assess the qualitative subtleties of Western civilization’s socio-cultural and scientific progress, from the time of antiquity until today, a very striking picture will emerge – the pace of this progress appears to have been gaining exponential momentum during the time of antiquity (5th century B.C. 5th century A.D.) and during the time of comparatively modern era (15th-20th centuries). However, during the course of so-called Dark Ages (6th – 14th centuries), the pace of Western socio-cultural and scientific progress came to virtually a complete stall – all thanks to Catholic Christianity.3 Therefore, it comes as not a particular surprise that it was specifically the exposure of Biblical fables’ anti-scientific essence, on the part of European most prominent intellectuals, which created the initial preconditions for Western civilization to be set back on its natural track of development.4 And, there can be very little doubt that Erasmus Darwin (1731-1802) was one of these intellectuals. In his poetical work The Botanic Garden; a Poem in Two Parts, supplemented by scientific commentaries, Darwin went about promoting a revolutionary idea that people and plants are being subjected to the same laws of nature.Advertising Looking for research paper on environmental studies? Let's see if we can help you! Get your first paper with 15% OFF Learn More In its turn, this implied plants’ sexuality: â€Å"The first buds of tree raised from seed die annually and are succeeded by new buds by solitary reproduction; which are larger or more perfect for several suc ­cessive years, and then they produce sexual flowers, which are succeeded by seminal repro ­duction†.5 Nevertheless, it were not the explicit references to the very n otion of sexuality, quite unconventional for its time, which ensured Darwin poem’s progressive sounding, but the fact that this poem suggested the physiological origins of a number of purely metaphysical notions, such as ‘soul’. As a result, Darwin’s poem ended up promoting clearly positivist message that it is the existence that defines consciousnesses, and not the other way around. As it was noted by Reed: â€Å"If life, mind, and feeling are concomitants of the arrangement of organs and of a fluid ether in animal bodies, what role was left for either God or the soul? Erasmus Darwin†¦ argued that the way we act is a function of our upbringing- of social, not divine intervention†.6 It goes without saying, of course, that such Darwin’s botanical stance was wholly inconsistent with the very spirit of anthropocentrism, based upon Judeo-Christian tradition, which contributed rather substantially to poem’s scientific value. After all, even during the course of 18th century, Church continued to exert a strong influence onto the essence of socio-political dynamics in British society. And yet, Darwin proved himself intellectually honest and courageous enough to utilize his poetic talent for the purposes of enlightenment, while defying the conventions of anthropocentrism. What is particularly interesting, in this respect, is the fact that he went about accomplishing it by the mean of endowing plants with clearly anthropocentric psychological traits – whatever the ironic it might sound. In The Botanic Garden; a Poem in Two Parts, flowers are being represented as such that can experience a variety of different emotions: Whilst erythrina oer her tender flowerAdvertising We will write a custom research paper sample on Anglo-Germanic Writers’ Influence on Popular Environmental Thinking specifically for you for only $16.05 $11/page Learn More Bends all her leaves, and braves the sul try hour;- Shield, when cold hesper sheds his dewy light, Mimosa’s soft sensations from the night.7 Thus, even though in Darwin’s poem, plants can be formally referred to as God’s creations, under no circumstances can they be referred to as some sort of God’s commodity. Just as it is being the case with people, in this poem, plants appear to have a life of their own. And, even though The Botanic Garden; a Poem in Two Parts is not being concerned with promotion of the concept of evolution, by being exposed to plants’ sexuality, readers come to suspect the existence of dialectically predetermined links between flora and fauna. Thus, it will not be much of an exaggeration, on our part, to suggest that Charles Darwin’s Theory of Evolution partially derives out of his grandfather’s insights, in regards to biological commonality between just about all life-forms. The irony lies in the fact that both: Erasmus and Charles’s insightful ness in the matters of biology appears to be of essentially Lamarckian nature. As Barlow had put it: â€Å"Erasmus’s cast of mind appears to hold special heritable qualities When we examine the achievements and characteristics of his (Charles Darwin’s) forbears and descendants, the copious mind of Erasmus appears as a vast family aggregate†.8Advertising Looking for research paper on environmental studies? Let's see if we can help you! Get your first paper with 15% OFF Learn More Apparently, the example of Erasmus Darwin shows that in 18th century, the sheer vibrancy of the process of Western empirical sciences freeing themselves out of Christian imprisonment had put era’s most prominent intellectuals at liberty to utilize just about any creative techniques, while popularizing scientific notions. The legitimacy of an earlier suggestion can be also explored in regards to one of 19th century’s most famous ornithologists John Gould (1804 – 1881). Just as it used to be the case with many intellectually advanced enthusiasts of science at the time, Gould took an interest in a number of scientific pursuits. Contemporaries considered Gould a professional in the fields of taxidermy, gardening, naval navigation and zoology.  Nevertheless, it was namely his love of birds, which did not only allow Gould to ensure its fame as ornithologist but also to contribute to the process of Charles Darwin designing the concept of natural selection. According to Pycior: â€Å"Darwin has been described as being ‘frankly stunned’ by Gould’s telling him that the Galapagos finches were a peculiar group of thirteen species, all closely related to one South American finch, that Galapagos mockingbirds belonged to three distinct species from different islands, and that twenty’, Current Anthropology, 26/4 (1985), 503. 2 Joel Mokyr, ‘Technological Progress and the Decline of European Mortality’, The American Economic Review, 83/2 (1993), 325. 3 Andrew Keitt, ‘Religious Enthusiasm, the Spanish Inquisition, and the Disenchantment of the World’,  Journal of the History of Ideas, 65/2 (2004), 233. 4 Arthur Melzer, ‘The Origin of the Counter-Enlightenment: Rousseau and the New Religion of Sincerity’, The American Political Science Review, 90/2 (1996), 350. 5 E.

There is no population crisis! essays

There is no population crisis! essays There is no world population crisis. There are lots of major countries with population problems, but it is also true that some dont have a population anywhere near to uncomfortable so it is not reasonable to categorize the world having a population crisis. Popular belief tells of recourses running out, perhaps a Water World in the not too distant future, but this is not possible, for It is integrally dependent on human ingenuity (Richmond, Sheldon). There is no possibility a shortage of living space either. If the entire world population moved to Texas, each person would have 1,400 square feet(Richmond, Sheldon). The world is huge, and we still have not discovered all of it. None the less we will not run out of area. Third World alone could support more than 30 billion people. The world's population now is only 5.6 billion.(Smith, Janet There is no World population problem Univ. Dallas 1994) We inhabit only 3% of the worlds landmass. We will always have land to live on. Yes, the resources in this world are limited, but it will not be exhausted because as long as man has the power to evolve, invent, and improvise we will think of ways to be more efficient, or substitute a more abundant resource with a seemingly rare material. This could not be more apparent than Silicon, for computer chips, and glass, for fiber optic cables. Both are made from silica, which, after oxygen, is the most common element on earth. It is sand! Thus, human beings took a common, abundant material, applied their ingenuity (in the form of, for example, quantum mechanics), and created unprecedented wealth.(Richmond, Sheldon). This subject goes back to lack of area; imagine if technology was developed to live under water. Countries have population problem, not the world. These counties have a population difficulty because they have the values different form some other countr...

Homestasis - Thermoregulation and control of blood sugar Essay

Homestasis - Thermoregulation and control of blood sugar - Essay Example The hypothalamus effects changes in response to alterations in body temperature by activating adjustments to effectors in the form of muscles manipulating body hair movement and operation of the sweat glands. Hence, the human body’ temperature can only be regarded as stable provided that the heat produced matches heat lost. The sustenance of the temperature of the body at a steady level is paramount given that the living processes within the cells closely depends on the action of the enzymes that work effectively in a set of stable conditions, especially at optimal temperature and pH. Any alterations in the set properties influence the utility of the enzymes and can yield to the death of the cells, and, ultimately, the death of the whole organism. This stresses the significance of regulation and sustenance of a constant internal environment. Nevertheless, the internal environment may not be entirely constant as it may be tolerated to fluctuate, albeit at exceptionally constric ted limits. Indeed, temperature regulation is imperative given that the speed of metabolic reactions is directed by enzymes activity that only functions optimally at temperatures that neighbor body’s core temperature of 37Â °C. ... Devoid of enzymes activity, much of critical bodily functions would fail to take place at the required level, which leads to the death of the cells. Q2 How the body gain and lose heat The outside temperature mainly differs significantly as the day progresses; however, the body temperature ought to be sustained at the core temperature of 37Â °C. This is well demonstrated in Jamel’s case given must be sustained at a constant 37Â °C with minimal variations while the outside environment is bound to change (Sircar 2008, 697). Given that the temperature in New York City stood at 10Â °C and there is a possibility that the temperature fluctuated prior the race, during the race, and after the race, Jamel’s body must adapt to the changing external environment. This is achieved via a number of processes through which the body is subjected to, namely: vasodilation, sweating, shivering, and vasoconstriction (Sircar 2008, 697). During the race in which Jamel’s body temperat ure rises owing to the rise in metabolism, the sweat glands located within the skin are activated to secrete/release sweat on to the surface of the skin. The action of evaporation of sweat from Jamel’s body’s surface yields to rapid cooling of the body, which, in turn, yields a drop in body temperature. How Jamel’s body Generate Heat Body energy (heat) is essentially gained through the action of two critical methods, namely: energy generation through metabolic and energy acquisition from environmental. Jamel’s body heat generation and preservation are facilitated by a number of factors: (1) increased muscular activity such as via shivering, which entails the transfer of stored chemical energy, which yields to a net increase in body heat around the skeletal muscle that flows

Managing Business Operations - Supply Chain Essay

Managing Business Operations - Supply Chain - Essay Example In order to meet its customers’ demand by providing quality services they decided to introduce IT in their business operations. Later on they ended up with problems as there was no integration between the systems of different units. Every individual department maintained its own account of activities properly but had no knowledge of what is happening in other departments. The lack of integration between different departments often created problems for the company. Thus, managing and integrating the affairs of all the units and departments became a tough task for a single person. Most often problems were detected after its occurrence. There are many processes involved in their business, beginning from order for freight to dispatch of the freight at the desired destination. The customer here is the company who places the order for transportation. The first process is the receipt of order from the client. Based upon the order, the company locates and sources the goods. The next p rocess is packaging of the sourced goods. Packaging is the process that requires intensive care. Goods may be breakable, or of exploding or evaporating nature etc. Each type of goods must be appropriately packaged so that no loss occurs to the customer due to destruction of goods. Dispatch of defective goods also affects the credibility of the company. The goods are packed and insured by MLH to secure the goods from loss in transit.
