Instructions
In this paper, you will select a
topic related to child or adolescent development and will analyze the topic in
an 8 page minimum paper (8-12 pages) to be completed and submitted by October 20th 2013 @4pm. Analysis requires breaking a subject, issue, or
even into its constituent elements so that the assumptions or components are
made clear and the relationships between them identified. Thus, through the
analysis piece, you will demonstrate comprehension of the material being
analyzed. This paper is not a personal opinion or response piece. It must
analyze the issue and be supported by references to scholarly publications.
The second half of the assignment will include the Applications piece which
uses the Analysis piece as its foundation. This portion of the paper will
include recommendations that could be used to address and improve the situation
(e.g., what needs to happen in the future) analyzed in the first portion of the
paper. Application requires the development of ideas based on the writings of
published experts reviewed in the first portion of the paper (with proper
citation, of course). First, you analyzed an issue and now you will demonstrate
the ability to apply what you have learned and suggest possible solutions
and/or future research or programs. For example, if the Analysis portion of
your paper focused on attachment issues that adopted children may face, the
Application portion of your paper should discuss ways that the Social Services
system, adoptive parents, and therapists can both prevent and treat such
attachment issues. Another example: discuss the issues that adolescents face as
they reach puberty and begin to develop sexually (analysis portion). Discuss
issues related to STD's, teen pregnancy, and the emotional implications of
becoming sexually active as a teen. For the Application portion, discuss what
types of programs you feel could be helpful in educating teens about the risks
of sexual behavior. How can schools and parents reach kids before they become
sexually active?
Your paper must be developed using research material from at least five
sources. One of these sources may be your textbook. You may also use the web
for some of your material. HOWEVER, please note that "popular"
websites (e.g., WebMD, Time Magazine, etc...) do not qualify as scholarly
sources, and that Wikipedia is NOT an acceptable source for an academic paper.
All sources must be listed on a "References" page using correct APA
citation format. You must include an Abstract Page and properly format your
Title Page (e.g., using header and page number in upper right hand corner and
Running head). You must also cite sources within the body of your paper whenever
you directly quote or paraphrase from an outside source. Both the citations in
the paper body and on the reference page must be formatted per the rules of the
American Psychological Association (APA), 5th Edition. Your papers should each
contain a cover page with your name and the title. Papers are to be typed and
double-spaced throughout using a font size no larger than size 12. The pages
should be full and margins should be no larger than 1 inch on all sides (except
for the top margin, which should be 0.75"). The cover page and references
page do not count toward the 8-page minimum length of the paper.
I have also included the Rubric that will be used to grade your Paper in the
Week 7 packet (titled "Paper Rubric"). Please refer to this to see
how your paper will be graded and to emphasize the importance of proper usage
of APA Style and good grammar and writing mechanics.
