\ CLASSROOM AND LAB CONDUCT POLICY

\

\  

\

\  

\

\ The number one thing to remember in my class is respect each other.

\

\  

\

\ I try to keep a loose, laid-back attitude in my classes with plenty of open discussion during and after lectures. If any one becomes too disruptive, they will be asked to leave the class and to meet with me after class for a private discussion. Failure to follow the conduct policy will result in grade reduction or other disciplinary action.

\

\  

\

\ Rules

\

\ 1.    No chewing tobacco, snuff, dip, sun flower seeds or anything else that requires the use of a spit cup.

\

\ 2.    In the class room you may bring in drinks; however, if any cups, empty bottles, glasses, and etc... are left for me or the janitorial staff to pick up, this privilege will be rescinded.

\

\ 3.    No horse play will be tolerated in either the class or labs.

\

\ 4.    Do not interrupt when someone is talking to me or visa-versa. If you want to make a comment in a discussion, wait for a pause in the action or raise your hand and I will call on you.

\

\ 5.    During my lecture, if you missed something or did not understand something, you may interrupt me for clarification.

\

\ 6.    When walking in the halls during breaks or when going to the lab, keep your voices very low as there are other classes going on.

\

\ 7.    If you smoke, you must wait until a break and then go outside the building. DO NOT THROW YOUR BUTTS ON THE GROUND.

\

\ 8.    Cell phones will be turned off or silenced. Cell phone calculators will not be allowed during any testing. If it becomes necessary, you will have two options: surrender your phone to me during class or leave the class for the day.

\

\ 9.    In the labs do not touch any project or equipment unless you are instructed to. You could ruin someone’s project or get into something that will get you hurt.

\

\ 10.   During labs, you will stay with your own project station and leave everyone else alone unless you are invited or instructed to assist someone else.

\

\ 11.   Do not wonder the halls during lab. If you do without permission you will be warned then if necessary asked to leave for the day.

\

\ 12.   Any and all safety procedures that I instruct will be adhered to.

\

\ 13.   BE ON TIME! & DON’T LEAVE EARLY WITHOUT CHECKING WITH ME.

\

\ 14.   The required text book for this course will be brought to every class beginning no later than the third session. Failure to bring book will result in 5 pts reduction of daily grade.

\

\ 15.   Required tools will be available at all lab sessions. If you don’t bring your tools, you may be asked to leave and points will be deducted for the day’s lab session.
