Course Grading:
This course will be graded on what is very close to a straight scale. I reserve the right to alter the scale if
I deem it necessary, but under no circumstances will these thresholds be raised making it more difficult
for you to achieve a good grade. The overall course grade will be calculated according to the following
breakdown:

CEM 262 — Quantitative Analysis — Fall 2014
Syllabus and Course Calendar
Experiments (50%): This is a quantitative analysis course, and the grade for each experiment will be
based almost entirely on the accuracy of your results. Important keys to your success are your use of
proper laboratory techniques and careful planning. Labs are considered timed practical exams, and as
such, you should work alone, and not provide to or accept any data or results from anyone else. You will
submit your lab results on a “report card” (provided by your TA) no later than the beginning of your
recitation period on the due date for your Section (see the table below). Cards turned in after the due
date/time will be assessed a penalty of 10 points. No lab results will be accepted after 5:00 pm on the
last day of classes, Friday, 4/25/2014. No lab results will be accepted other than by submitting the normal
“report card” to your TA or to me. NO E-MAIL SUBMISSIONS WILL BE ACCEPTED.
Experiments 1, 3, 4, and 5 are worth a maximum of 100 points each. Experiments 2, 6, and 7 are worth a
maximum of 110 points each because properly formatted graphs must be prepared with graphing software
(e.g. Microsoft Excel or Synergy’s KaleidaGraph, etc.) and submitted with the report cards for these
experiments. In this way, the maximum points available for all 7 experiments is 730 points.
You may redo an experiment as many times as you like in the allotted time, but your grade will be determined
by the LAST results you submitted, NOT by your best results! Each time you redo an experiment you must
obtain a different unknown from your TA.
You may attend only the lab session to which you are enrolled. Exceptions may be made in the case of
excused absences, but only with prior approval from me – not your TA. To obtain an excused absence
make-up, be prepared to provide evidence. Also, it is the responsibility of students who plan to be absent
from class at certain times throughout the semester, due to religious holidays or other valid reasons,
to make arrangements in advance with the instructor. If a make-up exam is approved, the instructor
retains the right to determine the content of the exam and the conditions of administration, giving due
consideration to equitable treatment.
Labs begin the SECOND WEEK of classes. The due dates for the experiments are given by the week in
which they are due in the table below:

CEM 262 — Quantitative Analysis — Fall 2014
Syllabus and Course Calendar
Important: Once the laboratory course has started, you perform the 7 experiments at your own pace. The
Guideline Dates indicated in the table above show the latest date the experiments should be started, and
if these guideline dates are followed, you should have no problem in completing the labs in the time allotted, though not leaving any time for redoing any experiments. The Due Dates indicated for the reports
for the individual experiments are not flexible. Any results turned in after the due date will be penalized
10 points. As noted above, and if time allows, experiments may be repeated in an effort to improve your
grade, and results from the redone experiments do not have to follow the timetable indicated above, but
if they’re turned in after the Due Date, the 10-point penalty applies. Remember: your last results determine your grade, not your best results. You may turn in results early without penalty. During your lab session, you must be properly attired, have appropriate safety goggles, and you must have your laboratory
notebook or you will not be allowed to work in the lab.
Laboratory performance/laboratory notebook (5%): Five percent (5%) of your course grade will be based
upon your laboratory/notebook performance as assessed by your TA. Your use of proper safety practices,
care of equipment such as balances and pH meters, your ability to work independently, willingness to
understand and follow instructions, and proper use and maintenance of your laboratory notebook are
among the things that will be considered in the assessment of this portion of your grade. Guidelines
for your notebook (including an example lab entry) are provided in the beginning of the lab manual.
Unannounced notebook inspections will be conducted by your TAs throughout the term. Any scraps of
paper containing laboratory data will be confiscated during an inspection, or at any other time they are
discovered. It is imperative to ALWAYS properly record all of your data directly into your lab notebook.
Homework (5%): Homework assignments will done through the LON-CAPA system which is accessed
over the Web at http://lon-capa.msu.edu (be sure to enable pop-ups in your browser for this web site).
Log on to the LON-CAPA system using your MSUNetID. Assignments are given periodically, each of which
include several problems to work. You can make as many as 99 attempts to solve each problem, but
grading is based only on whether you answered the problem correctly; the number of attempts it took you
makes no difference. The goal is for you to get practiced in working problems and thereby improve your
problem solving skills.
Recitations (5%): ATTENDANCE IN RECITATION IS VERY IMPORTANT TO YOUR SUCCESS IN THIS COURSE.
TAs will be demonstrating proper lab techniques, providing insight into the best strategy for preparing and
performing experiments, and discussing the calculations involved in reporting your experimental results.
TAs will also answer questions about the concepts presented in lectures and homework problems. Lab
report cards will be turned in at the BEGINNING of recitation on tor before the due date or they will be
marked “late”, and receive the 10-point penalty. There will be in-class assignments and quizzes to facilitate
the understanding of lecture topics. Your attendance and, most importantly, participation & performance
in recitation will be evaluated by your TA and considered as 5% of your grade.
Examinations (35%, combined) There will be two in-class one-hour examinations, on Wednesday,
October 8, 2014 and Wednesday, November 12, 2014. Each of these examinations will test the course
material which has been covered up to that point, and each will be worth 10% of your final grade. No
cellphones/computers/tablets, etc., may be used during an examination; only a dedicated calculator is
allowed.
The Final Examination will be on Thursday, December 11, 2014 at 7:45–9:45 AM in Room 101 Biochemistry,
and will be a comprehensive examination on all the material (lectures and experiments) covered throughout
the semester. The Final is worth 15% of your final grade.
