 Student Conduct/Class Rules

I try to keep a friendly, non-hostile environment in the class. I apply all rules and regulations evenly and fairly.

COVID-19. School policy states everyone is required to wear a face mask in the classroom, labs,hallways, breakrooms, and bathrooms. This includes those who have already had the virus as well as those that have received the vaccine.  

Attendance

There are 16 scheduled sessions. Students will receive full attendance points for holidays and official school closings.
Mid-term and Final exam sessions are mandatory. No excused absences and no exam make-ups.
You will clock in and clock out of each session on the computer in room 116. The time clock entries will be the final word on attendance verification.
Class starts at 6:00 PM Tardiness will result in loss of attendance points for any session.
Class ends at 9:50 PM. Leaving early will result in loss of attendance points for any session.
You are responsible for acquiring notes and homework assignments from fellow students when you are absent.
Home work is due at the first of the following session after is has been assigned. If you are absent when the assignment was made, it is still due at the following session.
Failure to turn in homework on time will result in a 20% reduction on the homework when turned in at the following session. A paper that is two sessions late will receive a grade of 0.
There are no mid-term or final exam make up tests.

Conduct

The main thing to remember is to respect each other.
Cell phones are to be silenced during class. Texting, gaming, taking non-emergency calls, and etc is not permitted. No cell phone usage is allowed in labs. Students who choose not to follow this rule will have the option of surrendering their phone to me for the class or leaving the class for the day.

Shirts are to be tucked in and hats are to be removed.
It is permissible to bring in food or drinks into the class room. No food or drinks are allowed in the labs or computer labs. If a student does not pick up and properly dispose of food wrappers, cans, and bottles, then the food and drink privilege will be revoked for all students.
No smoking on campus.
No chewing tobacco, dip, snuff, sunflower seeds, or anything else that requires a spit cup.
During class lecture I encourage open discussion; however, when a student asks a direct question to me, I need everyone else to be quite and let me respond. After I have answered the question, anyone wanting to add to or question the answer is welcome to jump in. This is fair to all students and will prevent confusion as to what is the proper answer.
Please be considerate of other classes going on in the building and keep your voices down when you are in the hallways during break.
Anyone that causes a disruption will be asked to leave the class.
Bring text book and tools to class every session.
Infractions of any of the above will result in grade reduction for the day and/or disciplinary action.
