BEHS 220 E221 Diversity Awareness (2152)
Applied Final Project - (25%): DUE LAST DAY OF CLASS
BEHS 220 students are required to submit a final project which
is worth one quarter of the final course grade. This project
should reflect the student’s highest level of work. The Personal
Action Plan for Diversity Consciousness requires students to
reflect on what they have learned about diversity understanding,
awareness and skills through a practical exercise which
culminates in a final 5 to 7 page paper promoting diversity at
the individual, community, and even global level. Because
communication is a vital skill in promoting diversity awareness,
this written project is expected to be thoughtful, well-organized,
and well-written. Students may wish to consult with the
Effective Writing Center and Information and Library Services
for guidance.
The Personal Action Plan will consist of a written final
product in which the following items are addressed:
PERSONAL GROWTH: 36 possible points
· Reason(s) for taking the course? (4 points)
· What are at least two ways in which my “diversity awareness”
has been affected by taking this class? (8 points)
· What are at least two ways in which my “diversity
understanding” has been affected by taking this class? (8
points)
· What are at least two ways in which my “diversity skills” have
been affected by taking this class? (8 points)
· What are at least two steps that I need to take to become a
more diversity conscious individual? (8 points)
DIVERSITY BENEFITS: 12 possible points
What are at least three specific benefits that I will gain from
valuing diversity? Support your response with evidence from
your text and/or other materials (e.g. personal journals and
Discussion posts, in-class presentations, external sources)
DIVERSITY COMMUNICATION: 16 possible points
· What is the role of communication in promoting diversity

15. awareness? Provide in-text citations from your text and/or other
external sources. Use APA format. (8 points)
· What are at least two ways in which I will improve my
communication skills to help others work more productively
with me? (8 points)
DIVERSITY GOALS: 8 possible points
What are at least two of my most important diversity goals for
the future?
DIVERSITY ACTIONS: 16 possible points
· What are three specific ways I will achieve my diversity goals
and contribute to creating an environment that values diversity?
(Specify whether contributions will have a personal, community
or global impact) (12 points)
· What resources will I need to honor these commitments? (4
points)
COMPOSITION AND MECHANICS: 12 possible points
· Writing is clear, concise and comprehensible (4 points)
· Errors in spelling, punctuation, capitalization, syntax,
grammar, etc. are minimal and do not detract from the author’s
meaning (4 points)
· In-text citations and references are properly cited using APA
style (for assistance with APA style, consult Information and
Library Services) (4 points)
FORMAT OF THE REPORT:
· Length: Your report will be 5-7 double spaced pages in length,
not including the title page or reference page
· Font: 12 point; Arial or Times New Roman
· Margins: 1 inch on all sides
· Pagination: Page numbers should be included on every page
except the title page.
· Title Page: Should include the title of your report and your
name centered on the page.
· References: Your last page should list all of the sources you
have used in alphabetical order and in APA format.
· Citations: Remember to cite any language, information or
ideas that are not your own in order to avoid plagiarism. In–text

16. citations and references should be in APA format.
· Tone: This is a formal written assignment. Avoid using jargon,
slang, contractions or colloquialisms.
· Syntax: Grammar, spelling, capitalization and sentence
construction are important. Always proofread your work!
· Resources: Students are encouraged make use of the UMUC
Effective Writing Center as well as Information and Library
Services when preparing their Personal Action Plans.
