A STUDY OF THE POSITIVE EFFECT OF EXTRACURRICULAR ACTIVITY ON ACADEMIC ACHIEVEMENT IN THE DISTRICT OF COLUMBIA’S HIGH SCHOOLS
Background
One of the most pressing issues facing school systems is the need to improve academic achievement while struggling with continued budge limitations. Washington DC Public Schools is one school system struggling with academic achievement under budgetary constraints. The District has 83.4% of its students are African American, 9.9% are Hispanic, 5.0% are White, 1.6% are Asian/Pacific Islander, and 0.1% American Indian/Alaskan Native (IES, 2007).
The district had significant gains of 8% and 11% respectively on reading and math in the elementary level and 9% and 9% respectively gains in reading and math on the secondary level for the 2008 District of Columbia Comprehensive Assessment System (DC CAS). The annual per-pupil expenditure is $13,780 for the district’s students ranking third national only to New York and New Jersey.
Do to the district’s declining tax base; the district’s public schools are at a crossroads in finances. The Washington Post (2009, January 19) indicated that Fairfax, Montgomery, Prince Georgie’s, Prince William, Anne Arundel, Loudon, Howard, Charles, Arlington, Calvert, St. Mary’s, and Alexandria Counties along with D.C. Public Schools face enormous budgetary burden. With the down turn in economic activity, home sales slowed and declining value of existing homes, automobile sales, and job loss; the tax coffers are dwindling. Therefore, schools systems have to cut spending, many of the extracurricularactivities are under the budget ax, at the same time “No Child Left Behind” (NCLB) standards are increasing (NCLB, 2001).
According to the National Assessment of Educational Progress (2007), the District of Columbia’s eight graders rank last according to the proficiency index score. There are budget challenges facing the District of Columbia Public Schools, however, none of the challenges are specific to this school district, neither are some of the solutions.
Research Questions
Four research questions are going to be explored with this particular study. The questions are as follows:
1. What effect does athletic participation have on student GPA’s?
2. What effect does athletic participation have on student DC CAS math scores?
3. What effect does athletic participation have on student DC CAS English Reading scores?
4. What effect does music participation have on student GPA’s?
5. What effect does music participation have on student DC CAS math scores?
6. What effect does music participation have on student DC CAS English Reading scores?
Limitations
This is limited to the tenth grade students in the first semester of school year 2008 – 2009. One hundred and fifty students will comprise the control group of students not involved in any extracurricular activity and one hundred and fifty students will make up each of the two experimental groups, one of athletes and one group of music students.
Research Design
This is a quantitative study using t test for independent means used at the 0.05% level of significance in order to determine the comparative results of students involved in the athletic or extracurricular activities with students not involved in either activity. Students will be randomly selected using random stratification for all three groups.
