EVALUATION METHODS: 

(1)  Teams for Problem Solving:  All homework and Excel assignments will be worked in teams.  The minimum size for a team is 2, and the maximum size is 3.  A single paper will be turned in for each team.  Everyone on a team will receive the same grade.  Twenty points will be deducted from each assignment for an individual not participating on a team.  Form your own teams before the first assignment is due.  A majority vote by team members can remove a team member who is not contributing to team output.  A person can change teams without the permission of other members of the team. You need not notify me when you form teams nor when the membership of a team changes.  Team members should exchange e-mail addresses so that it is not necessary to meet in person. 

(2)  Homework (HW). 

 (A) Homework will be randomly checked for completeness. I may ask a person to read their answer or place it on the board.  I may collect the work from the entire class or a part of the class.  Homework is due the first class meeting after we finish a chapter (except for the last chapter before an exam which is due on the last class day before the exam).

(B) You do not have to get the "right" answers to earn full  credit for the assignment.  All that is required is an  honest effort to work all of the assignments (show all work). We will go over assignments in class so that you can check on the accuracy of your work.

(C) Please make a photo (or hand written) second copy of all homework. The second copy (not handed in) will enable you to check your homework in class before I hand you back the checked first copy.  We will usually go over homework the day it is handed in.        

 (D) You can do the HW  (which sometimes includes Excel work) in three different ways:

 (1)  Write the HW by hand and cut and paste printed Excel output including grid lines and cell equations into the HW.
(2)  Use a word processor to do the HW and copy and paste Excel output into the document (show gridlines and cell equations in Excel part).
(3)  Do the entire assignment  in Excel (including questions that do not require Excel) and print from Excel (show gridlines and cell equations in Excel part).   In any case, clearly mark and identify the Excel work when doing HW.  If you do not have a personal copy of Excel, it is installed in all the computer labs on campus and the Student Lounge, room 105 in the CBA.

(E) No late homework accepted without prior notice. Examinations (details below) will contain problems very similar to the assigned homework.  Homework will count 15% of the course grade.

 (3)  Excel Computer Assignments         

(A)  Assignments using Microsoft Excel ?97 or 2000 will be made during the semester.  The program is available on all PCs at the Learning Resource Center, all other NAU labs and in the Student Lounge in room 105 in the CBA.  You may print you work at the LRC (to the small printers) or make a copy of you file and finish/print it elsewhere.

(B)  I will not teach the entire Excel software in class.  I will provide Excel examples in class and post detailed instructions for Excel commands on the class Web page for BA201 under "Excel Commands? (link provided on BA321 web page).  The optional Eldredge textbook (see above) is highly recommended.   The required Kvanli textbook (see above) also provides Excel instruction and a CD-ROM with an Excel add-in. I reserve the right to make extra Excel assignments during the semester.

 (C) The Excel assignments must be done in Excel (show gridlines and cell equations).

(D) No late work accepted without prior notice. Excel exercises will count 25% of the course grade.

 (4)     Examinations:  Bring picture identification to each exam.  Your id may be checked during exams.

(A) There will be two exams (totaling to 35% of the course grade) during the term and a final exam (25% of the course grade) given during the finals period. You will receive an estimated midterm grade after each midterm exam. 

[1] All exams are open notes and  open text .  The exams may be of any form.  The following is the schedule of the exams:
[2] Midterm Exam #1  Chapters 7 and 8  (15% of semester grade)
[3] Midterm Exam #2  Chapters 9, 10 and 11 (20% of semester grade)
[4] Final Exam  Comprehensive with emphasis on Chapters 13, 14 15 and the balance of work covered, on                 Tuesday, Dec. 11, 7:30-9:30AM (25% of semester grade) 

(B)  Makeup exams:  There will be no makeup for midterm exams. A missing midterm exam grade will be allowed only for those people with proper documentation or a legitimate excuse (and tell me in advance of missing the regularly scheduled exam).  In that case, the final exam will count 40%, 45% or 60% of the course grade depending on the number of exams missed.  Bring a copy of the documentation and a picture id to the final exam. This policy applies to only those people indicated above.  It will not be applied to anyone who misses an exam without with proper documentation of a legitimate excuse. 

(C) Letter grade assignment will be determined for each exam based on your grade compared to the average of the top 5% of the grades in your class.  For example, if the average on Midterm Exam of the top 5% of the grades is 95.0, then 95.0 will be considered to be 100.0%.  So, if your raw score was 86.0, then your adjusted grade would be 86.0/95.0 = .905 = A.  Your rounded grade on an exam may not exceed 100%.  Grades from all my sections may be pooled for rounding.  After such rounding is carried out for the Midterm Exams and the Final Exam, no other rounding of course grades will take place.  Excel and HW grades will not be rounded. 

(D) We will go over the exams in class as soon as possible after the exam date.  If you miss class the day theexam is reviewed, then do not expect to be able to go over your exam with me in detail in my office.  You may see your exam on an individual basis in my office, but you may not keep copies of your exams nor study your exams in my office or at home.  I will answer any questions that concern your individual exam in my office, and I will be glad to explain why you missed questions. 

(5) Course Grade:  The lowest course average for a grade of A is 89.5, for a B is 79.5, for a C is 69.5, and for a D is 59.5.  A grade of F is recorded for averages below 59.5. 

(6)  Posting of Grades on the Web. According to University rules, you must give me your permission to have your grades posted by the last four digits of you ID# to the web page. You may also supply me with a four digit number as a substitute. Please respond by e-mail with your permission to use the last four digits of your ID# or the substitute number. Put "BA321" and your last name somewhere in the subject line of all e-mail during the semester.

NORTHERN ARIZONA UNIVERSITY POLICY STATEMENTS

(1)  SAFE ENVIRONMENT POLICY 

NAU's Safe Working and Learning Environment Policy seeks to prohibit discrimination and promote the safety of all individuals within the university. The goal of this policy is to prevent the occurrence of discrimination on the basis of sex, race, color, age, national origin, religion, sexual orientation, disability, or veteran status and to prevent sexual harassment, sexual assault, or retaliation by anyone at this university.   

You may obtain a copy of this policy from the college dean's office. If you have concerns about this policy, it is important that you contact the departmental chair, dean's office, the Office of Student Life (523-5181), the academic ombudsperson (523-9368), or NAU's Office of Affirmative Action (523-3312). 

(1)  STUDENTS WITH DISABILITIES 

If you have a learning and/or physical disability, you are encouraged to make arrangements for class assignments/exams so your academic performance will not suffer because of the disability or handicap. If you have questions about special provisions for students with disabilities, contact the Counseling and Testing Center (523-2261). 

It is your responsibility to register with the Counseling and Testing Center. Application for services should be made at least eight weeks before the start of the semester. 

If the Counseling and Testing Center verifies your eligibility for special services, you should consult with your instructor during the first week in the semester so appropriate arrangements can be made. Concerns related to noncompliance with appropriate provisions should be directed to the Disability Support Services coordinator in the Counseling and Testing Center. 

(3) INSTITUTIONAL REVIEW BOARD 

Any study involving observation of or interaction with human subjects that originates at NAU-including a course project, report, or research paper-must be reviewed and approved by the Institutional Review Board (IRB) for the protection of human subjects in research and research-related activities.

The IRB meets once each month. Proposals must be submitted for review at least fifteen working days before the monthly meeting. You should consult with your course instructor early in the course to ascertain if your project needs to be reviewed by the IRB and/or to secure information or appropriate forms and procedures for the IRB review. Your instructor and department chair or college dean must sign the application for approval by the IRB. The IRB categorizes projects into three levels depending on the nature of the project: exempt from further review, expedited review, or full board review. If the IRB certifies that a project is exempt from further review, you need not resubmit the project for continuing IRB review as long as there are no modifications in the exempted procedures.

A copy of the IRB Policy and Procedures Manual is available in each department's administrative office and each college dean's office. If you have questions, contact Carey Conover, Office of Grant and Contract Services, at 523-4889.  

(4) ACADEMIC INTEGRITY 

The university takes an extremely serious view of violations of academic integrity. As members of the academic community, NAU's administration, faculty, staff, and students are dedicated to promoting an atmosphere of honesty and are committed to maintaining the academic integrity essential to the educational process. Inherent in this commitment is the belief that academic dishonesty in all forms violates the basic principles of integrity and impedes learning. Students are therefore responsible for conducting themselves in an academically honest manner. 

Individual students and faculty members are responsible for identifying instances of academic dishonesty. Faculty members then recommend penalties to the department chair or college dean in keeping with the severity of the violation. The complete policy on academic integrity is in Appendix F of NAU's Student Handbook.  

(5)  CLASSROOM MANAGEMENT STATEMENT 

Membership in the academic community places a special obligation on all members to preserve an atmosphere conducive to a safe and positive learning environment. Part of that obligation implies the responsibility of each member of the NAU community to maintain an environment in which the behavior of any individual is not disruptive.

It is the responsibility of each student to behave in a manner which does not interrupt or disrupt the delivery of education by faculty members or receipt of education by students, within or outside the classroom. The determination of whether such interruption or disruption has occurred has to be made by the faculty member at the time the behavior occurs. It becomes the responsibility of the individual faculty member to maintain and enforce the standards of behavior acceptable to preserving an atmosphere for teaching and learning in accordance with University regulations and the course syllabus.

At a minimum, students will be warned if their behavior is evaluated by the faculty member as disruptive. Serious disruptions, as determined by the faculty member, may result in immediate removal of the student from the instructional environment. Significant and/or continued violations may result in an administrative withdrawal from the class. Additional responses by the faculty member to disruptive behavior may include a range of actions from discussing the disruptive behavior with the student to referral to the appropriate academic unit and/or the Office of Student Life for administrative review, with a view to implement corrective action up to and including suspension or expulsion.
