Codes of Academic Integrity and Student Conduct

Students are required to uphold the Code of Academic Integrity and the Code of Student Conduct. Students who violate either of these codes may receive a failing grade in the class.  Information about these codes and other student policies, procedures, and penalties is available on the Student Policy and Procedures web page at http://www.frederick.edu/student_services/studentpolicies.aspx .

 

 

Student Services

A variety of services are available to assist students in succeeding at FCC. Students can learn more about these services by visiting the Student Services web page: http://www.frederick.edu/student_services/index.aspx

 

Students with disabilities who are in need of accommodations or who have questions related to disabilities services should contact the Services for Students with Disabilities (SSD) office at 301-846-2408. Students can learn more about these services by visiting the Services for Students with Disabilities web page: http://www.frederick.edu/student_services/disability.aspx .

 

 

Participation Policy

The College attendance policy states:  "Students are expected to attend all class sessions except in cases of emergency, religious holidays or participation in official College functions.  In these cases, notification or verification, if requested, will be given to the instructor by the student."

 

Attendance is expected for all classes. If you miss a class it is your responsibility to find the assigned material either from another student or from the instructor. You should not expect to achieve your potential if you miss classes. If you don’t come you will miss out on material that will make it easier for you to achieve the course objectives.

 

Expectations: I will show respect to each of you and expect you to show respect towards me and your classmates. This specifically includes refraining from talking during the lectures.  If you are talking to the point that it is distracting to me while lecturing, it will also be distracting to your classmates.  I will let you know once only if this is a problem, and after the second time, I will reassign seats. See the 2010-11 Student Handbook for more detail on expected classroom behavior.

 

I expect you to put your cell phones in silent mode when you enter class.

I will start class on time and be prepared to teach the entire period.

I will answer email within 24 hours.

I will return graded tests during the next class after a test.

I will be available during my office hours.

 

 

Email Communication

All students will receive and be expected to use their FCC email address for their correspondence with faculty and staff at the college.  Students can establish and access their FCC email accounts at the login page: https://myfcc.frederick.edu.

 

 

Topical Outline

Every effort will be made to keep to this schedule; however, the instructor reserves the right to alter or amend it as necessary. Additional dates, as published in the academic schedule of classes and listed below, may be required as make-up days for inclement weather.
