30 Million Word Gap
The term 30-million-word gap (often shortened to just word gap) was originally coined by Betty Hart and Todd R. Risley in their book ''Meaningful Differences in the Everyday Experience of Young American Children'', and subsequently reprinted in the article "The Early Catastrophe: The 30 Million Word Gap by Age 3". In their study of 42 Midwestern families, Hart and Risley physically recorded an hour's worth of language in each home once a month over 2½ years. Families were classified by socioeconomic status (SES) into "high" (professional), "middle/low" (working class) and "welfare" SES. They found that the average child in a professional family hears 2,153 words per waking hour, the average child in a working-class family hears 1,251 words per hour, and an average child in a welfare family only 616 words per hour. Extrapolating, they stated that, "in four years, an average child in a professional family would accumulate experience with almost 45 million words, an average child in ...

Social Class In The United States
Social class in the United States refers to the idea of grouping Americans by some measure of social status, typically economic. However, it could also refer to social status or location. The idea that American society can be divided into social classes is disputed, and there are many competing class systems. Many Americans believe in a social class system that has three different groups or classes: the American rich, the American middle class, and the American poor. More complex models propose as many as a dozen class levels, including levels such as high upper class, upper class, upper middle class, middle class, lower middle class, lower class and lower lower middle class. while others disagree with the American construct of social class completely. Most definitions of a class structure group its members according to wealth, income, education, type of occupation, and membership within a hierarchy, specific subculture, or social network. Most concepts of American social clas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Child Development
Child development involves the Human development (biology), biological, developmental psychology, psychological and emotional changes that occur in human beings between birth and the conclusion of adolescence. Childhood is divided into 3 stages of life which include early childhood, middle childhood, and late childhood (preadolescence). Early childhood typically ranges from infancy to the age of 6 years old. During this period, development is significant, as many of life's milestones happen during this time period such as first words, learning to crawl, and learning to walk. There is speculation that middle childhood/preadolescence or ages 6–12 are the most crucial years of a child's life. Adolescence is the stage of life that typically starts around the major onset of puberty, with markers such as menarche and spermarche, typically occurring at 12–13 years of age. It has been defined as ages 10 to 19 by the World Health Organization. In the course of development, the individu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Language Acquisition
Language acquisition is the process by which humans acquire the capacity to perceive and comprehend language (in other words, gain the ability to be aware of language and to understand it), as well as to produce and use words and sentences to communicate. Language acquisition involves structures, rules and representation. The capacity to use language successfully requires one to acquire a range of tools including phonology, morphology, syntax, semantics, and an extensive vocabulary. Language can be vocalized as in speech, or manual as in sign. Human language capacity is represented in the brain. Even though human language capacity is finite, one can say and understand an infinite number of sentences, which is based on a syntactic principle called recursion. Evidence suggests that every individual has three recursive mechanisms that allow sentences to go indeterminately. These three mechanisms are: ''relativization'', ''complementation'' and ''coordination''. There are two ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Education Issues
Education is a purposeful activity directed at achieving certain aims, such as transmitting knowledge or fostering skills and character traits. These aims may include the development of understanding, rationality, kindness, and honesty. Various researchers emphasize the role of critical thinking in order to distinguish education from indoctrination. Some theorists require that education results in an improvement of the student while others prefer a value-neutral definition of the term. In a slightly different sense, education may also refer, not to the process, but to the product of this process: the mental states and dispositions possessed by educated people. Education originated as the transmission of cultural heritage from one generation to the next. Today, educational goals increasingly encompass new ideas such as the liberation of learners, skills needed for modern society, empathy, and complex vocational skills. Types of education are commonly divided into formal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Achievement Gap In The United States
Achievement gaps in the United States are observed, persistent disparities in measures of educational performance among subgroups of U.S. students, especially groups defined by socioeconomic status (SES), race/ethnicity and gender. The achievement gap can be observed through a variety of measures, including standardized test scores, grade point average, dropout rates, college enrollment, and college completion rates. The gap in achievement between lower income students and higher income students exists in all nations and it has been studied extensively in the U.S. and other countries, including the U.K. Various other gaps between groups exist around the globe as well. Research into the causes of the disparity in academic achievement between students from different socioeconomic and racial backgrounds has been ongoing since the 1966 publication of the Coleman Report (officially titled "Equality of Educational Opportunity"), commissioned by the U.S. Department of Education.

No Child Left Behind Act
The No Child Left Behind Act of 2001 (NCLB) was a U.S. Act of Congress that reauthorized the Elementary and Secondary Education Act; it included Title I provisions applying to disadvantaged students. It supported standards-based education reform based on the premise that setting high standards and establishing measurable goals could improve individual outcomes in education. The Act required states to develop assessments in basic skills. To receive federal school funding, states had to give these assessments to all students at select grade levels. The act did not assert a national achievement standard—each state developed its own standards. NCLB expanded the federal role in public education through further emphasis on annual testing, annual academic progress, report cards, and teacher qualifications, as well as significant changes in funding. While the bill faced challenges from both Democrats and Republicans, it passed in both chambers of the legislature with significan ...

Raciolinguistics
Raciolinguistics examines how language is used to construct race and how ideas of race influence language and language use. Although sociolinguists and linguistic anthropologists have previously studied the intersections of language, race, and culture, raciolinguistics is a relatively new focus for scholars trying to theorize race throughout language studies. Geneva Smitherman credits H. Samy Alim for the coinage of the new term, discussed at length in the 2016 book by Alim, John R. Rickford and Arnetha F. Ball which compiled raciolinguistic research. In their work, raciolinguists incorporate intersectionality in theorizing how various identities (e.g. gender, ethnicity, nationality) within a group and/or an individual influence lived experiences of race. Nelson Flores and Jonathan Rosa also used the term in their discussion of "appropriateness" in American language and education. Drawing from sociolinguistics and linguistic anthropology, raciolinguistics focuses on race and its rela ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
