Introduction

The concept of equity in academic achievement for all students, regardless of ethnicity, is an issue that has captured the attention of politicians, educators, and the federal government since the 1960s with the implementation of the Elementary and Secondary Act of 1965 (Frankenbeg&Lee, 2002; Yell&Drasgow, 2005). The Elementary and Secondary Act (ESEA) was soon followed by the report, A Nation at Risk, in which the low achievement levels of students within the American school system were detailed (A Nation at Risk, 1983). In 2001, the No Child Left Behind Act (NCLB) was created and signed into law (No Child Left Behind, 2002).

The No Child Left Behind Act is based on “four key principles which grants greater accountability and adaptability when using funds for schools, school districts and states; more freedom and power in selection of schools for disadvantaged parents; and greater options for teaching methodology, based on empirical research” (2002, p. 9). The aim of the NCLB Act was to create opportunities for all students to be successful, regardless of their academic background, ethnicity, or socio-economic status (No Child Left Behind, 2002; Yell&Drasgow, 2005). One intention behind the implementation of the NCLB Act was to increase state and local accountability, which therefore would ideally increase the equity of all subgroups on a national level by the school year 2013-2014.

The creation and implementation of the NCLB Act has generated both support and criticism of its effectiveness in decreasing the achievement gap between White students and ethnic minority students (Celeste&Stokes-Brown, 2009; Kim&Sunderman, 2005; Lee, 2002; Lee&Wong, 2004; Powers, 2004; Ravitch, 2009; Rothstein&Jacobsen, 2009; Schiller&Muller, 2003). Proponents of the law argue that the NCLB Act has been successful and has made a lasting effect in diminishing the achievement gap between White students and minority students (Weaver, 2006; Zavadsky, 2006). Researchers have documented the success of the NCLB Act and increased success of school districts across the nation (Jennings&Rentner, 2006; Miners, 2007; Mixed Reactions to NCLB, 2005; Packer, 2007; Zavadsky, 2006). Yet, critics have argued that the NCLB Act has been a burden to school districts, personnel, and students alike (Borkowski&Sneed, 2006; Frankenberg&Orfield, 2006; Jennings&Rentner, 2006; Lewis, 2007; Manzo&Hoff, 1997; Mixed Reactions to NCLB, 2005; Tyler, 2003; Zeus, 2007). Opponents of the NCLB Act, recognizing that test scores have increased, have commented that achievement is in relation to most schools’ focus on test taking skills (Guilfoyle, 2006; Popham, 2007; Smyth, 2008) rather than a legitimate increase in achievement.

Theoretical framework

Acquisition of language and literacy, specifically vocabulary, is the catalyst for future success and academic achievement in school (Kosmoski, Gay,&Vockell, 1990). The success of minority children in education stems from the knowledge and understanding of their family, community and societal influences (Tabors&Snow, 2001). To create academic achievement among students of minority backgrounds, educators must implement strategies that encourage family and communities to support educational success (Foster, 2004). To understand how to create educational success among minority students, an understanding of the dynamics within the community and culture must be demonstrated (Frankenburg, Lee,&Orfield, 2003). The understanding of culture and academic achievement has been conceptualized by Ogbu (1981) in the creation of the cultural-ecological (CE) theory.

Questions & Answers

What is price elasticity of demand and its degrees. also explain factors determing price elasticity of demand?
Yutansh Reply
Price elasticity of demand (PED) is use to measure the degree of responsiveness of Quantity demanded for a given change on price of the good itself, certis paribus. The formula for PED = percentage change in quantity demanded/ percentage change in price of good A
GOH
its is necessarily negative due to the inverse relationship between price and Quantity demanded. since PED carries a negative sign most of the time, we will usually the absolute value of PED by dropping the negative sign.
GOH
PED > 1 means that the demand of the good is price elasticity and for a given increase in price there will be a more then proportionate decrease in quantity demanded.
GOH
PED < 1 means that the demand of the good is price inelasticity and for a given increase in price there will be a less then proportionate decrease in quantity demanded.
GOH
The factors that affects PES are: Avaliablilty of close substitutes, proportion of income spent on the good, Degree of necessity, Addiction and Time.
GOH
Calculate price elasticity of demand and comment on the shape of the demand curve of a good ,when its price rises by 20 percentage, quantity demanded falls from 150 units to 120 units.
Helen Reply
5 %fall in price of good x leads to a 10 % rise in its quantity demanded. A 20 % rise in price of good y leads to do a 10 % fall in its quantity demanded. calculate price elasticity of demand of good x and good y. Out of the two goods which one is more elastic.

what are some of the difference between monopoly and perfect competition market
Obeng Reply
n a perfectly competitive market, price equals marginal cost and firms earn an economic profit of zero. In a monopoly, the price is set above marginal cost and the firm earns a positive economic profit. Perfect competition produces an equilibrium in which the price and quantity of a good is economic
Naima
what are some characteristics of monopoly market
Obeng Reply
explicit cost is seen as a total experiences in the business or the salary (wages) that a firm pay to employee.

what is taxation
Peter
is the compulsory transfer of wealth from the private sector to the public sector
Jonna
why do monopoly make excess profit in both long run and short run
Adeola Reply
because monopoly have no competitor on the market and they are price makers,therefore,they can easily increase the princes and produce small quantity of goods but still consumers will still buy....
