Due Dates: Dues dates are included in the Course outline. Please contact me if in doubt
to any due dates. There are no quizzes during the weeks of exams. The "due dates" are
"due by dates." You may turn assignments in early. If a quiz or exam is not activated,
please contact me. Discussions posted after the due date will not be graded.
On-line Course
The advantage of this online course is that you don't have to come to campus. There are
similarities to the face-to-face course though. You have deadlines and one semester to
complete the work. A high percentage of students who attempt this style of course have
difficulty completing the work on time - not because there is too much work, but
because time management is difficult without the stimulus of facing your teacher three
or four times a week. Plan your time intelligently so you can succeed. The class room
version of this course is 3 hours of lecture and 3 hours of lab each week, plus time to
study on your own. So use this to estimate the time you need to spend for this course.
I will generally answer emails within 24 - 48 hours. The class is not a 24/7, synchronous
environment. It is asynchronous. When you are on the computer, I am probably not. I
may look in once in a while in the evening or weekend, but not habitually. Use the
Discussion Board to communicate with the rest of the class as a discussion would occur
in the classroom. Remember, it is asynchronous and the replies will not be immediate.
Ask course related questions of your classmates. The Discussion Board is the forum for
that purpose. You can ask questions of me directly through email or through the
Discussion Board. The Discussion Board is a public (class) forum. If you email me at my
email address, it is more likely to be private (as secure as email can be guaranteed).
Homework: At the end of each chapter there are homework problems. You are assigned
the odd numbered problems and there are answers at the back of the book in Appendix
A. If you need help, please ask me. I will not collect homework for credit. You need to do
the problems in order to do well in the course. If those go well, try the even numbered
problems. The more you practice, the better you will get. It is a good idea to review the
Appendix A1 to A17 before starting the course material.
To succeed in the class: You need to be persistent in reading the book, doing the
homework, and asking questions. I won’t be giving out review guides for the exams.
What will be on the exams? The PowerPoint material is not the sole information guide
to the course. It will narrow down what is in the text. There won’t be any surprises. The
problems on the test may not be exactly like the ones in the homework, but you will
know how to solve them. You have the tools to solve the problems. You will have the
algebra skills to do the problems required in this course. You will need to use the
information in the course to solve problems. Learn the material, ask questions, and be
active.
Grading:

Evaluation Criterion
The exams and quizzes are graded immediately, unless you exceed the allotted time. I
will try to grade and get your labs back to you within a week.
Exams:
We will have four (4) exams and all exams will be counted. Each exam is worth 100
points; Total = 400 points. The exams will be given via the Blackboard exam function.
The exam format is multiple-choice exams; you will have 40 questions to answer in 60
minutes. Please be prepared to take the exams when they are given. Looking up the
material while taking the exam takes a lot of time and you will most likely run out of
time before you can finish the test.
Quizzes:
We will have 12 quizzes and I will drop the 2 lowest quizzes. 10 quizzes will be
counted and each quiz will be worth 20 points; Total = 200 points. The quizzes will be
given via the Blackboard exam function. The quiz format is multiple choice; you will
have 10 questions to answer in 20 minutes. Please be prepared to take the quizzes
when they are given. Looking up the material while taking the quiz takes a lot of time
and you will most likely run out of time before you can finish the quiz.
Papers:
There will be 1 short paper to complete. Topic and instruction for the paper are
described in the assignment. Paper will be worth 20 points; Total = 20 points.
Discussions:
I have set up two types of Discussion boards for you to use, the first type is
informational only and in it is general/icebreaker, lecture (chapter) material, and lab
experiments. I am starting the discussion thread by giving an overview of the specific
Chapter and Experiment for that week. Some videos are included here to help
understand the concepts. These are the places to ask questions of your classmates as a
study group of sorts. You communicate with the rest of the class and help each other.
Use the discussion board to post your experiences and/or share your thoughts on
Chapter topics and Labs. Helpful suggestions are encouraged.
The second type is graded Discussion board. There will be topics/threads that involves
some critical thinking and minor research, and the score counts towards your grade.
During the semester there will be 8 topics/threads and you post your discussion here.
Each topic will be worth 10 points; Total = 80 points.
Lab Safety:
Review safety in laboratory handout and answer the questions; you must complete it
before you start the labs. Total = 25 points
Labs:
We will have 14 labs and I will drop 3 lowest lab scores. 11 labs will be counted and
each lab will be worth 25 points; Total = 275 points. You must pass the laboratory
portion of the course, must complete at least 9 labs, to pass the entire course. The
lab reports need to be completed using a word processor. Tables and graphs are
easily created using the programs like MS Office and inserted into your document.
You should send them to me as an attachment via Blackboard.
LABORATORY REPORT FORMAT:
Lab report format and rubric is given below. The lab grade is a compilation of the
actual performance of the experiment (including techniques), the questions related to
the lab. Completed lab reports will normally be due the following week. The lab
report needs to be submitted via Blackboard's Assignment function. Late reports are
not given full credit and may or may not be accepted by the instructor. A decision will
be made after discussing the reason with the instructor. The student must collect his
or her own data. SAFETY GLASSES and APPROPRIATE ATTIRE MUST BE WORN AT ALL
TIMES WHILE DOING THE EXPERIMENTS.

Note: Points will be deducted if the lab report is not neatly prepared or data and the
units are not correct. Lab reports must be submitted via Blackboard the week
following the experiment for grading. Late submissions may result in a 20 %
deduction.
Note: The purpose should be no more than two sentences and include a statement in
your own words of the principles being investigated. Do NOT just retype the
procedure from the manual. Put it in your own words in sufficient detail that you
could carry out the experiment without reference to the lab manual. Procedure must
be written in such a way that if someone wants to repeat the experiment can do this
easily.
Data, observation and calculations sheet: All your measurements are reported here.
Don't just report the final results. The reader needs to know where your results
originate. This must be neatly typed. Tables are an excellent way to organize
observations and information. Where applicable, the "Procedures" section of the
experiment instructions often advises a table format for data recording. Always set up
and draw out any tables before experimenting. What did you observe, smell, hear, or
otherwise measure? Remember, observations are often most easily recorded in table
form.
Advance study questions or Post-labs: Post lab questions are given after the
experiments in you lab manual. All Students are required to do post-labs
independently. Copying among students or group partners is prohibited. If I find
identical answers or proved to be copied, in that situation a person who is cheated or
a person who let others to be cheated are equally treated at the time of the grading.
Such act will be reported to the administration.
A typed conclusion: The conclusion should address the summary of what you have
learned. Write what difficulties you noticed during the experiment. Have you
understood the techniques involved or you want to suggest modifications? Give
suggestion, only a statement is not enough. Conclusion should be one or two
paragraphs of your results with your own interpretation or hypothesis. Turn in the
entire report.
Helpful suggestions for your Labs:
Safety is very important. Know how to handle the chemicals you are going to use in
each experiment. Know how to safely dispose the chemicals after the experiment.
Give enough time to start and complete your experiments. Have a clean and safe area
to do your experiment.
Introduction part of the lab manual is good, so read and understand it.
Read the experiment few days before you plan to do the experiment. Check the items
you need, especially student supplied materials. Have everything you need for the
experiment and organize and get familiar before you start.
Know that you have limited resources for each experiment; best is to follow the steps
in the procedure, mock practice and then use the chemicals for your experiment.
Before you start the experiment, have the blank data sheet and know what data you
need to collect. This helps you to observe and record the correct information.
Start the experiment, follow the procedure step by step, observe, and record your
data. Make sure you have all the data for the experiment to complete your report.
Clean up your area. Follow manual instructions and dispose off waste items.
Complete your report and submit it through BB.
Course Polices
Withdrawal Policy
You may withdraw up until the “Last Day to Withdraw without Instructor Permit” (see
the Registration Calendar) through myACCESS or in person at the Registration office,
Student Resource Center (SRC), Room 2048.
After the “Last Day to Withdraw without Instructor Permit” date (see the Registration
Calendar), you may withdraw only with your instructor’s written permission. The
instructor’s permission to withdraw must be brought or faxed to the Registration office.
The registration fax number is (630) 790-3785. You will NOT be automatically
withdrawn.
Check COD Calendar for last day to withdraw for 16-Week Course without instructor
consent. (April 12, 2013)
Incomplete Policy
If you find that you are unable to complete the course by the end of the term for an
unavoidable reason you may request an Incomplete grade. Incomplete grades will only
be given for extreme situations. Contact the instructor for more information.
Satisfactory/Fail Policy
This course qualifies as a general graduation requirement course. If this is your reason
for taking Chemistry 1105, you must think very carefully before choosing the S/F option.
Very few transfer schools will accept the S grade for a general graduation requirement
course, and COD's associate programs do not. If you are contemplating requesting this
option, check with your chosen transfer school and make sure that, for the program you
wish to enter, it is acceptable that this class receives an S grade. If you decide that this is
what you want to do, the S/F grade option form must be filled out and signed by both
student and instructor, then submitted by the instructor with the grade sheets at the
end of the semester.
Note that the S grade is for "Satisfactory." This is not the same as "Passing." In this class,
the S grade will be assigned only for work at the C level or better. (In other words, a D is
passing but not satisfactory.)
