DECLARATION OF A MAJOR

 

         Students enrolled in this course who plan to complete a certificate or a degree should officially declare a major and request a faculty advisor in the area of their major.

 

         The procedure for declaring a major is as follows:

 

         1.     Request a Declaration of Major form from the Office of Admissions and Records.

 

         2.     Meet with a counselor in Counseling and Assessment or a faculty member in your major to clarify certificate or degree selection.  Return completed form to Counseling and Assessment or to the faculty member who gave you the form.

 

         3.     Receive notification of an advisor assignment by mail after processing is completed.  Some degree programs have a special application procedure and require that a student be assigned to a counselor before being admitted to the program.  For Diversified Studies majors, degree plans must be submitted for approval to the Office of Academic Division Support Services.  Contact a counselor for additional information.

 

Goggle Policy

 

You are required to purchase your own pair of chemical splash goggles and to wear those goggles at all times in the laboratory.  You may purchase your goggles in the OCCC bookstore.  If you choose to purchase goggles elsewhere, they must be approved by your professor.  Woodworking goggles are NOT acceptable. 

 

“Loaner” goggles are no longer available for your use.  If you forget your goggles, you must purchase another pair from the OCCC Science Center (or Bookstore) to use or you must complete the lab as a make-up (with all associated late penalties).

 

The OCCC Chemistry faculty has a zero tolerance policy on goggle violations.  Failing to wear or removing your goggles during lab may result in dismissal from the laboratory and a grade of zero for that lab.  Repeated violations of the goggle or safety rules and policies may result in a grade of “F” for the course.

 

GRADING

 

         The grade assigned for this course will be determined by your performance on unit tests, a comprehensive final, online quizzes, and lab assignments.  Detailed information about each grading area is outlined below. 

 

         1)  Exams.  There will be seven unit exams worth 100 points each plus a comprehensive final exam worth 50 points for a total of 750 points.  The final exam will be given at the same time as the last unit exam unless otherwise specified in your lecture schedule.  You are expected to take all exams in class.  If you miss the in-class exam, you must take the make-up exam in the Test Center within 7 calendar days.*   If you do not take the exam in the specified time, you will receive a zero for that exam.  Ten percentage points will be deducted from the make-up exam score regardless of the reason for missing the in-class exam.

 

         If you take a unit exam in class and receive less than 60%, you may re-take that exam.*   You will receive the higher score from the two exams up to a maximum of 70%.  All re-tests must be completed within 14 days of the day the exam was given in class.  You may not re-test on the comprehensive final exam or on a make-up exam.

 

         *You are limited to a total of two retests and/or make-up exams during the semester.  In other words, you can re-test on two units you failed, you can make up one exam and re-take one exam you failed, or you can make up two exams.

 

            2)  Quizzes.  There will be seven online quizzes given throughout the semester.  Quiz questions will often be taken directly from or based upon homework problems.  Each quiz is worth fifteen points giving a total of 105 points possible on the quizzes.    No make-up quizzes will be given, and no late quizzes will be accepted.  A score of zero will be recorded for any missed quiz.  Due dates for quizzes will be specified by your instructor (check your lecture schedule).  Typically, you will have about ten days to access and complete an online quiz.  You MAY ask your instructor for help with online or any homework problems.

 

Computer access for MasteringChemistry online quizzes:  Since each quiz is open for several days, technical problems discovered on the due date of a quiz are not considered a viable excuse for not completing the quiz on time.  We strongly recommend that you access each quiz on the first day it becomes available so that your instructor can help you resolve any technical difficulties you may encounter.  Although you do have to purchase access to MasteringChemistry, you do not have to access it with your own computer.  The computers in the Physical Science Center (or any student accessible computer on campus) may be used to access and complete your MasteringChemistry assignment.

 

         3)  Lab Exercises.  There are 12 lab exercises, eleven worth 10 points each and one lab worth 20 points.  Lab reports (data sheets) will be submitted to your lab instructor who will grade the reports.  The lab instructor will forward your lab grades to your lecture instructor at the end of the semester for use in determining your final grade.

 

         IN ORDER TO PASS THIS COURSE, YOU MUST COMPLETE AND RECEIVE A SATISFACTORY GRADE (≥ 2 pt) ON AT LEAST 10 OF THE 12 LAB REPORTS.

 

         You must do at least 10 of the 12 laboratory experiments -- you are expected to complete all 12 -- and submit completed data sheets for those labs.   There will be only one week in the semester that may be used to make up a missed lab, and we strongly advise you to complete all 12 labs and reports.  Although only 10 labs are required to pass the course, please understand that the lab grade consists of 130 points:  if you choose not to make up a lab, that lab grade will be a zero.

 

         Labs are due at the start of the following pre-lab period.  Late labs will be assessed a five point penalty.  Labs that are turned in after start of the pre-lab period will be considered late, regardless of the reason.   

 

         To receive full credit, all questions on the data sheet must be answered, appropriate calculations must be shown on the data sheet or on attached sheets of paper (as specified in the lab instructions), results must be within the expected range, and all calculations should be done according to the rules for significant figures.

 

         You can lose points on labs according to the following criteria:

            Late lab - 5 point penalty

            Incomplete lab report (i.e. some questions or calculations omitted) - 1 to 4 point penalty, depending upon how many calculations or questions are omitted

            Poor results - 0.5 to 2 point penalty, depending upon how bad the results are

            Calculation errors - 0.5 to 3 point penalty, depending upon how many errors are made

            Incorrect answers to questions - 0.5 to 1 point each

            Incorrect use of significant figures - 0.5 to 1 point penalty, depending upon how many errors are made

 

         (Notice that it would be relatively easy to fall below the 2 point minimum required for passing this class if you submit an incomplete data sheet with a few calculation errors and poor results or incorrect responses to questions.  Submitting a late lab means that you should take extra care in making sure the lab is complete and your calculations are correct so that you do not fall below the 2 point minimum.)

 

            4) Formal Lab Report.  You are expected to INDEPENDENTLY write and submit a formal lab report during the semester.  Your instructor will identify the specific lab for which a formal report is required and will provide you with the format for the formal lab report.  The formal report is worth 15 points.

 

Final Grade Calculation:

            Total points possible = 750 + 105 + 130 + 15 = 1000 points

 

Note:  You can get a pretty good idea of your standing in the class by looking at the average of your exams.  If your average is one or two points away from the next grade level, the points for the labs and quizzes could bring your final grade up to the next level.  For instance, if you have an 88 average on your exams, you can still get an “A” provided that you have most of the points for the labs and quizzes.  On the flip side, if you have done poorly on quizzes or a number of labs were late, your grade could potentially drop a letter grade. 

 

 

TRANSFERRING LAB GRADES

 

You must be enrolled in a section of CHEM 0110.  If you need to complete any labs at all, you will be expected to attend the first lab session to complete safety activities.  However, if you have completed some or all of the Chem 0110 lab work at OCCC within the past calendar year, you may transfer the grades for those completed labs to your current Chem 1115 lecture instructor and will only have to attend those labs which you did not complete previously.  To transfer your lab grades, please email Dr. Steven Shore at sshore@occc.edu the following information:  1) your name and student ID number, 2) the name of your former Chem 0110 lab instructor, 3) the name of your former Chem 1115 lecture instructor, and 4) the name of your current Chem 1115 instructor.  The request for lab grade transfer should be made by the end of the second week of class.

 

INCOMPLETES

 

         An "I" grade may be given to students under extenuating circumstances.  Please understand that the issuing of an "I" grade is the instructor's prerogative and not a "right" of the student.

 

ACADEMIC DISHONESTY

 

            Academic dishonesty (such as copying from someone else or using unauthorized notes on exams) will result in a zero being given for the work in question and a record of the incident will be forwarded to the Office of the Vice President for Academic Affairs.  Further disciplinary action may result. 

 

THINGS TO REMEMBER

 

         You are not allowed to use programmable calculators on tests or quizzes in class or in the Test Center.  A simple scientific calculator is all you need.

 

                

         For make-up exams or retests

 

                 1)    Know the Test Center operating hours!

                 2)    The Test Center will not give out tests later than one hour before closing time.

                 3)    You must have an OCCC photo ID to receive a test.

                 4)    The Test Center closes promptly at the posted times.  You will be required to turn in your test by closing time.

        5)    Make-up exams are subject to a 10 percentage point penalty and must be completed within 7 calendar days of the in-class exam.

                 6)    Re-tests on failed exams must be completed within 14 calendar days of the in-class exam.

                 7)    You are limited to a total of two retests and/or make-up exams during the semester.
