Text: Required – In Quest of the Universe, 4th Edition; by Karl Kuhn & Theo Koupelis

 

Tests:  The 3 lecture tests given will consists of a variety of question types including: T/F, Multiple Choice, Matching, and Short answer.

           

            A comprehensive final exam will be given during finals.

           

            Make-Up Tests will only be given when I have been notified in advance concerning the reason for absence during the test.  And the reason will have to be very good in order to be excused from the exam.

 

Labs:   After most of the labs there will be a worksheet, or lab write-up to be handed in.  Due dates for labs will be specified during the lab discussion.  Late labs will be accepted, with a substantial grade reduction, no later than one week after the lab session.

 

Homework:  Review questions at the end of each chapter in the textbook.  Although I will not be collecting and grading these, I strongly urge you to write out each of the answers.  There will be no better method of studying for tests and the final than going over the answers to these review questions and reading through your lecture notes.

Weekly Reports:  A variety of brief informational research projects that I will assign on a weekly basis. To receive full credit for a weekly report the following criteria must be met: 1) Report must be “On Topic”; 2) Reference(s) must be cited; 3) Reports must be typed (NOTE – you may email your papers to me at the address given above); and 4) Although I will not be “counting words”, consider ½ page a minimum length.

 

Daily Reports:  At the end of each class you will be giving the opportunity to makes comments or ask questions regarding the materials presented that day, or anything else within the bounds of the class.  You will be given 2 points for this report each day.  I find this a productive way of checking attendance. Don’t be late to class: If you come to class after I have begun the day’s lecture I will only give you 1 point for your Daily Report.

Excessive Absenteeism :  If you miss more than 6 classes during the quarter your grade will be lowered by one full grade! 

 

Cell Phones:  Please make sure your Cell Phone is turned OFF before coming to class. If your cell phone rings during class you will not receive any attendance points for that day. If it happens a second time during the quarter the penalty will be doubled, for a 3rd time, doubled again, etc. If you have the nerve to answer a call durning class I will deducted 25 points.

 

 

Grading:          Chapter Tests               40%

                        Final Exam                    20%

                        Labs                             20%

                        Weekly Assignments     10%

                        Daily Reports                10%

                                    (all the above percentages are approximate)

            Letter grades will be assigned using a modified curve.

Disability Identification and Accommodations: If you have a disability for which you are or may be requesting an accommodation, you are encouraged to contact both your instructor and the Disabilities Coordinator in the Student Development Center, 527-4258, as early as possible in the quarter.
