The Individuals with Disability Education Act Policy...

The Individuals with Disabilities Education Act (IDEA), which is a supersession of the Education of All Handicapped Children Act of 1975 is a federal law which requires states and their school districts to provide individuals with disabilities a free and appropriate education. IDEA governs how states and public agencies provide early intervention, special education and related services to more than 6.5 million eligible infants, toddlers, children and youth with disabilities. US Department Of Education (n.d.) The population that IDEA intends to effect is children between the ages of three and twenty one years of age who have a specific disability that has an adverse effect on the student’s performance. Children who qualify under IDEA are†¦show more content†¦In 1970 the educational needs of children with disabilities were not being met. Access to education and opportunities to learn were denied. In the United States, many states had schools that educated only one in five children with disabilities and many states had laws that excluded certain children with disabilities such as deaf, blind, emotionally disturbed or mentally retarded. US Department Of Education Education for All Handicapped Children Act of 1975 also known as Public Law 94-142 (P.L. 94-142) required a free and appropriate education to be provided to all children, regardless of their disability. This law also authorized financial incentives to enable states and localities to comply. In 1986, there was an amendment to the Education for All Handicapped Children Act of 1975. This amendment provided a more comprehensive program at the state level for early intervention for infants and preschoolers. Encyclopedia of Educational Psychology In 1990, Congress reauthorized P.L. 94-142 and renamed it the Individuals with Disabilities Education Act Public Law 101-476 (P.L. 101-476), also known as IDEA.

A Widow for One Year by John Irving - 1024 Words

A Widow for One Year by John Irving is comical as well as disturbing, a love story with intense emotional force. It is a brilliant novel about the passage of time, the persistence of grief, and the loss of innocence that occurs over time, which is why it would be a great fit for the American Literature curriculum. The Cole family stands out as a paradigm of dysfunction. Ted and Marian Cole, Ruth’s parents, never recovered from the deaths of their two sons, Timothy and Thomas, leaving them weary and broken. Their instability laid the groundwork for a life full of infidelity and a dysfunctional family situation. The novel is set in the mid to late 20th-century. It is full of bizarre coincidences, multiple plot lines, lengthy deviations, and stories within stories, quite like A Visit from the Goon Squad. Although it is set up in chronological order, the reader is exposed to various stories from three set periods in the life of the main character, Ruth Cole. The story begins in childhood and ends in womanhood, taking us through the transitions of Ruth’s life. The novel begins in the summer of 1958, on Long Island when Ruth is only four years old. In the first line of the novel, Ruth has a piece of her innocence stripped from her when she walks in to find her mother in bed with her lover. The narrative states that â€Å"There are few things as seemingly untouched by the real world as a child asleep† (151).

Essay on Personal Experience The Co-Founder of Room to Read

Hi, my name is Mary Doe , and I am a co-founder of Room to Read. Let me tell you a little bit about myself. I have always loved to read. In fact, Dr. Seuss’s children’s books were my favourite and I still keep them in my shelves today. Reading filled my imagination and gave me inspiration since childhood that still impacts me today. I can only think of a few things that are more powerful than a book. Though many of the people around us enjoy the luxury of having access to libraries and books everyday, that is not the case for the vast majority of people around the world.

It was a simple idea. We started off by partnering with schools to establish public libraries. We printed off books so we made sure the children had a print safe environment for learning. We trained teachers so that we make sure the children receive a proper education that is appropriate in both intellectual and cultural context. We also encouraged and helped girls stay in school and receive proper educations that they deserve as a human right as a lot of girls in many third world countries do not.

John Steinbeck (811 words) Essay Example For Students

John Steinbeck (811 words) Essay John SteinbeckJohn Steinbeck was born in February 27, 1902 in Salinas, California. Salinas wasan agricultural valley in California. His father was the county treasurer andhis mother was a schoolteacher. This is where his education began from a motherthat encouraged him to read. The community was a comfortable environment for himto live in because of the encouragement of independence and initiative. Hisparents didnt want him to be a writer. They wanted him to have a trueprofession as a lawyer. His early interest in reading led him through school,with his main interest in science. At age 15 he decided to become a writer,influenced by an English teacher, and faintly remembered by schoolmates forspending so much time in his room writing. After graduating from high school, hewent to Stanford University in 1920. While he was there for five he contributedto the school paper by writing poems and comics. He took courses in science andwriting, but never received a degree. In 1925, when he left Stanford, he becamea marine biologist. He moved to New York in 1925 to work as a reporter for anewspaper. Always being a non-conformist, he was fired from the newspaper forwriting opinions instead of facts. This started the many jobs he would be a partof in his lifetime. Some of these jobs include an apprentice hod carrier, anapprentice printer, a working chemist, caretaker of Lake Tahoe Estate, surveyorin Big Sur County, and a fruit picker. He also worked other more physicallylabored jobs, such as a rancher, road worker, deck hand, cotton picker, andbricklayer. While involved in these jobs, he made many close friends that hecame to admire because of their cant and hypocrisy which he applauded andwhom all of these people soon were characters in his novels. Many of theseexperiences were the helpers to his many novels. His fruit picking andGreat Depression led him to write The Grapes of Wrath, his best known and mostambitious of his works. Also, he wrote Of Mice and Men, which was fo rmed fromhis job as a hired hand on the many farms he worked. Many things affected hiswriting of the time period of which he wrote. Things like the Great Depression,World War 2, and the Vietnam War are the major influences. World War 2 was whenhe was working for the federal government as a writer, so his works focused ongreed and materialism in the beings of modern civilization, Cannery Row and TheWayward Bus are two good examples of this idea. After World War 2, he wrotemainly of several outcasts. The Grapes of Wrath was an influential piece fromthe Great Depression and the Dust Bowl that existed in California. It is aboutthe migration of farm families, leaving their old towns to become ghosttowns. A bit of inventions came into effect during this time period. Technology was changing the way that Americans lived and worked. The playerpiano was invented in 1905. Henry Ford Model T in 1908. Everyone has heard ofthe Titanic right? Well, it sunk in 1912. One of the most important things thathas ever happened in history occurred in 1921. Yes, your right, it was the dateof the first Miss America Pageant. The Great Depression began in 1928. The greatGolden Gate Bridge was also completed in 1937. John Steinbeck and F. ScottFitzgerald seemed to divide America up into a new age or era. Fitzgerald seemedto work more with the rich, finding pity and terror in them. Steinbeck took tothe growing of California, the Depression, and poverty. John Steinbeck won thePulitzer Prize award for his book The Grapes of Wrath in 1940. He also won theNobel Peace Prize award in 1962. He was the sixth American to win the NobelPrize for literature. His novel, Tortilla Flat, received the CaliforniaCommonwealth Clubs annual gold medal for the best novel by a Californiawrit er. It was adopted for the stage and sold to Hollywood. He focused somewhaton nature, with some humor, but seemed to have sympathy for theoppressed, misfits, and the distressed. He wrote about conflicts between hisfeelings for nature and his sympathy for human beings. To be natural and notrespectable, was in his fiction, the controlling force of the universe. He wasbest known for his basis on the American experience often with sympathetic focuson the poor, eccentric, or the dispossessed. The Grapes of Wrath, which he wrotein 1939, was his best known and most famous work. It won the Pulitzer Prize in1940. This book consisted of a family that migrated from the Dust Bowl toCalifornia to finally experience death, disease, and starvation. This book, likemany of his works, turned out to also be a famous movie. He was married 3 times. .uedac606271497c50c6a945babc7c8e0f , .uedac606271497c50c6a945babc7c8e0f .postImageUrl , .uedac606271497c50c6a945babc7c8e0f .centered-text-area { min-height: 80px; position: relative; } .uedac606271497c50c6a945babc7c8e0f , .uedac606271497c50c6a945babc7c8e0f:hover , .uedac606271497c50c6a945babc7c8e0f:visited , .uedac606271497c50c6a945babc7c8e0f:active { border:0!important; } .uedac606271497c50c6a945babc7c8e0f .clearfix:after { content: ""; display: table; clear: both; } .uedac606271497c50c6a945babc7c8e0f { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .uedac606271497c50c6a945babc7c8e0f:active , .uedac606271497c50c6a945babc7c8e0f:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .uedac606271497c50c6a945babc7c8e0f .centered-text-area { width: 100%; position: relative ; } .uedac606271497c50c6a945babc7c8e0f .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .uedac606271497c50c6a945babc7c8e0f .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .uedac606271497c50c6a945babc7c8e0f .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .uedac606271497c50c6a945babc7c8e0f:hover .ctaButton { background-color: #34495E!important; } .uedac606271497c50c6a945babc7c8e0f .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .uedac606271497c50c6a945babc7c8e0f .uedac606271497c50c6a945babc7c8e0f-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .uedac606271497c50c6a945babc7c8e0f:after { content: ""; display: block; clear: both; } READ: The Beatles To This Day Are One Of The Most Famous And EssayHe fathered two boys to his second wife.

Electricity and Magnetism free essay sample

As he was setting up his materials, he noticed acompass needle  deflected from  magnetic north  when the electric current from the battery he was using was switched on and off. This deflection convinced him that magnetic fields radiate from all sides of a wire carrying an electric current, just as light and heat do, and that it confirmed a direct relationship between electricity and magnetism. At the time of discovery, Orsted did not suggest any satisfactory explanation of the phenomenon, nor did he try to represent the phenomenon in a mathematical framework. However, three months later he began more intensive investigations. Soon thereafter he published his findings, proving that an electric current produces a magnetic field as it flows through a wire. The  CGS  unit of  magnetic induction  (oersted) is named in honor of his contributions to the field of electromagnetism. His findings resulted in intensive research throughout the scientific community in  electrodynamics. We will write a custom essay sample on Electricity and Magnetism or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page They influenced French physicist  Andre-Marie Amperes developments of a single mathematical form to represent the magnetic forces between urrent-carrying conductors. Orsteds discovery also represented a major step toward a unified concept of energy. This unification, which was observed by  Michael Faraday, extended by  James Clerk Maxwell, and partially reformulated by  Oliver Heaviside  and  Heinrich Hertz, is one of the key accomplishments of 19th century  mathematical physics. It had far-reaching consequences, one of which was the understanding of the nature oflight. Light and other  electromagnetic waves  take the form of  quantized, self-propagating  oscillatory  electromagnetic field disturbances called  photons. Differentfrequencies  of oscillation give rise to the different forms of  electromagnetic radiation, from  radio waves  at the lowest frequencies, to visible light at intermediate frequencies, to  gamma rays  at the highest frequencies. Orsted was not the only person to examine the relation between electricity and magnetism. In 1802  Gian Domenico Romagnosi, an Italian legal scholar, deflected a magnetic needle by electrostatic charges. Actually, no  galvanic  current existed in the setup and hence no electromagnetism was present. An account of the discovery was published in 1802 in an Italian newspaper, but it was largely overlooked by the contemporary scientific community. Electricity and Magnetism Electricity and magnetism is an interesting aspect of electricity. We are familiar with in our everyday lives with the phenomenon of static cling when two objects, such as a piece of Saran wrap and a wool sweater, are rubbed together, they cling. One feature of this that we dont encounter too often is static repulsion if each piece of Saran wrap is rubbed on the wool sweater, then the pieces of Saran wrap will repel when brought near each other. These phenomena are interpreted in terms of the objects acquiring anelectric charge, which has the following features: * There are two types of charge, which by convention are labelled  positive  and  negative. * Like charges repel, and unlike charges attract. * All objects may have a charge equal to an integral number of a basic unit of charge. * Charge is never created or destroyed. Electric Fields A convenient concept for describing these electricity and magnetism forces is that of an  electric field. Imagine that we have a fixed distribution of charges, such as on the plate below, and bring in the vicinity of this distribution a  test chargeQ. Figure 1  Test charge in the presence of a fixed charge distribution This charge will experience a force due to the presence of the other charges. One defines the electric field of the charge distribution as: The electric field is a property of this fixed charge distribution; the force on a different charge  Q  at the same point would be given by the product of the charge  Q  and the  same  electric field. Note that the electric field at  Q  is always in the same direction as the electric force. Because the force on a charge depends on the magnitude of the charges involved and on the distances separating the charges, the electric field varies from point to point, both in magnitude and direction. By convention, the direction of the electric field at a point is the direction of the force on a  positivetest charge placed at that point. An example of the electric field due to a positive point charge is given below. Figure 2:  Electric field lines of a positive charge Power and Magnetic Fields An electricity and magnetism phenomenon apparently unrelated to power are electrical magnetic fields. We are familiar with these forces through the interaction of compasses with the earths magnetic field, or through fridge magnets or magnets on childrens toys. Magnetic forces are explained in terms very similar to those used for electric forces: * There are two types of  magnetic poles, conventionally called North and South * Like poles repel, and opposite poles attract However, this attraction differs from electric power in one important aspect: * Unlike electric charges, magnetic poles always occur in North-South pairs; there are nomagnetic monopoles. Later on we will see at the atomic level why this is so. As in the case of electric charges, it is convenient to introduce the concept of a  magnetic field  in describing the action of magnetic forces. Magnetic field lines for a bar magnet are pictured below. Figure 3:  Magnetic field lines of a bar magnet One can interpret these lines as indicating the direction that a compass needle will point if placed at that position. The strength of magnetic fields is measured in units of  Teslas  (T). One tesla is actually a relatively strong field the earths magnetic field is of the order of 0. 001 T. Magnetic Forces On Moving Charges One basic feature is that, in the vicinity of a magnetic field, a  moving  charge will experience a force. Interestingly, the force on the charged particle is always perpendicular to the direction it is moving. Thus magnetic forces cause charged particles to change their direction of motion, but they do not change the  speed  of the particle. This property is used in high-energy particle accelerators to focus beams of particles which eventually collide with targets to produce new particles. Another way to understand these electricity and magnetism forces is to realize that if the force is perpendicular to the motion, then no work is done. Hence these forces do no work on charged particles and cannot increase their kinetic energy. If a charged particle moves through a constant magnetic field, its speed stays the same, but its direction is constantly changing. A device in which this property is used is the  mass spectrometer, which is used to identify elements. A basic mass spectrometer is pictured below. Figure 4:  Mass spectrometer In this device a beam of charged particles (ions) enter a region of a magnetic field, where they experience a force and are bent in a circular path. The amount of bending depends on the mass (and charge) of the particle, and by measuring this amount one can infer they type of particle that is present by comparing to the bending of known elements. Magnet Power From Electric Power A connection was discovered (accidentally) by Orsted over 100 years ago, who noticed that a compass needle is deflected when brought into the vicinity of a current carrying wire.
