Core Assessment:

Class Assessment:

Each week, students are required to engage in discussion among themselves by answering and commenting upon questions posed for that week.  Each week's discussion is worth 20 points, with 1-10 provided for content and 1-10 points provided for timeliness and substantive quality and quantity of replies to other students' postings.  Spelling, grammar and punctuation is counted as part of this grade. As a general rule, simple replies like "good comment" or "I agree" do not count as substantive.  Instead, you will be expected to provide personal viewpoints or pose significant questions to other students. As a minimum, at least four substantive discussion postings should be submitted each week, not counting the initial answers to the questions posed that week. 

Weeks 1, 3 and 5 each require a paper which provides the students opportunities to apply material learned from reading, virtual lecture and discussions.  Each paper carries a maximum of 100 points.   These papers must be at least 750 words and written in APA format.

During weeks 2, 4, 6 and 7 you will not have a weekly paper due, but will instead take a timed quiz.  In week 7 you will have the CORE paper as well as a quiz.  This CORE paper will be graded on a scale of 100 points, must be in APA format, and shall be not less than 1000 words in length. In this paper, you must use at least four sources of material that are not from the text or course lectures, and must be cited within the body of the paper. 

Please note that weeks 1, 3 and 5 have quizzes, but these are not part of your grade; they are only for your practice.

During the eighth week, a proctored final exam will be taken by the student which will combine multiple choices with short answer questions.  

Core Assessment: 
For your CORE assessment, provide an essay of not less than four pages or 1000 words in length (excluding the cover sheet, title sheet, Abstract and References pages) which addresses the issues below. The essay should be typed, written in APA format to include in-text source citations and use a minimum of four sources of material from outside the class. These papers are due by the last day of Week 7. 

Criminalistics and forensic science has grown both in scope and importance to the criminal justice system. There is no question that it compliments and aids in traditional investigations. However, as it has become more advanced and technical, has it come to have more importance than the traditional methods of investigating such as questioning eyewitnesses, interrogating suspects and determining information from street informants? In your answer, specifically address the following issues: 
· Explain how the use of forensic investigative techniques enables both prosecutors and defense attorneys to recognize and develop evidence in the prosecution of criminal cases and in the defense of the accused. 
· Discuss how forensic science is or is not better than these traditional methods and why. 
· Discuss whether courts and juries now place more trust in forensic science than other forms of information. 
· Provide your arguments that juries should or should not place more emphasis and trust in forensic science and your reasons for the argument. 

In providing answers to these issues, indicate specific types of forensic evidence that would apply and use trustworthy supportive examples wherever possible such as case law or case examples.

The grading scale is as follows: 
A = 90-100; 
B = 80-89; 
C = 70-79; 
D = 60-69; 
F = 0-59. 

The final exam will count 25% of your total grade, weekly discussion presentations will count 2.5% each week for a total of 20% of your course grade; the quizzes for weeks 2, 4, 6 and 7 count 2.5% each for a total of 10% of the course grade; Your papers for weeks 1, 3 and 5 are worth 5% each for a total of 15% of the total course grade. In Week 8, the CORE paper will be worth 30% of your overall grade. A grading chart is included to show the relative weights of each week’s work. 

Each student is responsible for: 
Completing weekly Reading assignments. 
Completing Weekly Discussion Questions and posting discussion questions or comments to other student’s discussion answers. 
Completing four writing assignments, referred to as Papers. 
Completing a CORE paper in Week 8 Completing a proctored Final Examination

Academic Honesty:
Academic integrity is the foundation of the academic community. Because each student has the primary responsibility for being academically honest, students are advised to read and understand all sections of this policy relating to standards of conduct and academic life. Park University students and faculty members are encouraged to take advantage of the University resources available for learning about academic honesty (www.park.edu/current or http://www.park.edu/faculty/).from Park University 2012-2013 Undergraduate Catalog Page 97

Plagiarism involves the use of quotations without quotation marks, the use of quotations without indication of the source, the use of another's idea without acknowledging the source, the submission of a paper, laboratory report, project, or class assignment (any portion of such) prepared by another person, or incorrect paraphrasing. from Park University 2012-2013 Undergraduate Catalog Page 95
Far too often, students have sent material to me that is the product of plagiarism.  Often it is material obtained verbatim off the internet, copied and pasted onto the paper without providing the proper citation, quotation marks or other manners of crediting the original author.  Sometimes it has been material purchased from on-line sources, and sometimes it has come from past students.  I have already said in the syllabus that neither the University nor I tolerate this, but let me go further.  In the academic world this is considered intellectual theft.  In my mind, however, it also indicates a lack of the ethics I consider crucial to those in the law enforcement field.  If I find that your work is the product of plagiarism, I will take appropriate action.  If I believe that it was done unknowingly or through carelessness, even after this warning, I will assess a grade of 0 to that paper.  If I receive further such papers, after you've been warned, or if I believe it is a flagrant, knowing violation, I will fail the paper and, depending upon the circumstances, may fail the student in the course and may recommend dismissal from Park University's undergraduate program.

Attendance Policy:
Instructors are required to maintain attendance records and to report absences via the online attendance reporting system.

  1. The instructor may excuse absences for valid reasons, but missed work must be made up within the semester/term of enrollment.
  2. Work missed through unexcused absences must also be made up within the semester/term of enrollment, but unexcused absences may carry further penalties.
  3. In the event of two consecutive weeks of unexcused absences in a semester/term of enrollment, the student will be administratively withdrawn, resulting in a grade of "F".
  4. A "Contract for Incomplete" will not be issued to a student who has unexcused or excessive absences recorded for a course.
  5. Students receiving Military Tuition Assistance or Veterans Administration educational benefits must not exceed three unexcused absences in the semester/term of enrollment. Excessive absences will be reported to the appropriate agency and may result in a monetary penalty to the student.
  6. Report of a "F" grade (attendance or academic) resulting from excessive absence for those students who are receiving financial assistance from agencies not mentioned in item 5 above will be reported to the appropriate agency.
ONLINE NOTE: Students must participate in an academically related activity on a weekly basis in order to be marked present in an online class. Examples of academically-related activities include but are not limited to: contributing to an online discussion, completing a quiz or exam, completing an assignment, initiating contact with a faculty member to ask a course related question, or using any of the learning management system tools.
