4. Class Preparation & Homework: Preparation,
Practice (Homework) and staying current with course content on
a daily basis are essential
to
your
success in this course of study. The choice of which
resources to use, the amount of preparation, practice, and the time
required will
differ for each of you. A scientific study of a very large sampling
of students at Notre Dame
University has shown that final grades in general chemistry are directly
related to the amount of time students invest. In order to score
well on exams & quizzzes, the questions to ask yourself while going
through this experience are, "Can I teach this concept to someone
else? And, can I recognize and correctly answer questions that are
similar to the
ones contained in
the
in-class i-clicker
response questions,
the
worksheets,
the on-line/textbook problems, and the class/lab activities?".
Correlating the time related to your answer to these questions will
provide an estimate of what you will likely need to invest. Exams will
be designed
to test content & concepts based on these materials. There will
be periodic chapter/topic quizzes that will also be based on
these materials. IT IS HIGHLY RECOMMENDED to first examine
all of the Course Resources, choose
to emphasize ones that best suit your learning styles and make a plan
of how you intend to use them, Once you have
a plan set,
put
it into
practice:
1) Frequently refer
to the course Calendar
page.Print & read
the on-line pdf Class Slides that are linked from the course calendar
and the Resources
page. Answer
all of the i-clicker questions before coming to each class. Take
in class notes on the printed .pdf slides, and record the i-clicker
answers. 2) Collaboratively
complete all worksheets in a group with 1 or 2-or 3 partners 3) Individually
complete
as many problems
for each in-class topic from any of the available resources: Zumdahl
textbook and/or Chem120:ChemWiki and/or ChemVantage (on-line homework/quiz
problems) as you think necessary & reasonably possible, Keep a separate
notebook
for your
problems which should
be neat and well-organized.(Not necessary for ChemVantage.)
Consulting the Zumdahl solutions guide or Chem:120:ChemWiki problem solutions
is recommended highly. Homework & Class
Notes will be collected at the end of each quiz and factored into
the quiz
score (ChemVantage will automatically record your homework results
from your submissions.), that
is, an
amount
of
up to
30%
of
the points
lost on
the quiz will be
added
back into the quiz grade. A related scheme will be employed for each
of the 3 "hour" exams, which will be explained in more detail
after the first Exam.
5. Grading:
i-clicker / in-class participation
are valued at 10% of the TOTAL grade. The
class portion of the grade is worth 65% of the total grade. It will
be comprised of quizzes
and worksheets,
(which
in
total equal one exam), 3 in-class exams, and a final exam, which is equal
to two hour exams. Tentative Exam Dates: 9/18,
10/23, 12/4, 12/16 (FINAL). A laboratory grade worth 25% will account
for the remainder of the total grade. Final letter grades will be assigned
based on: 90-100
A;
80-89
B; 65-79 C; 50-64 D;<50 F, using a normalized class average. NOTE: The
DVC Code of Conduct will be strictly enforced. Cheating
and plagiarism are unacceptable and will unconditionally result in
a failing grade. [Cell phones will not be allowed in rooms
during exams and quizzes.] SEE:
DVC Academic College Policies
6. Attendance / Tardiness / Absences:
On-time attendance at all scheduled
class and lab meetings is unconditionally expected..
If you arrive late for class or lab, you will be marked absent. Two
late arrivals will be excused provided that
you see Dr.
R. immediately after class or lab. If you are to miss a class, quiz,
exam or lab due to illness or other legitimate reason, you must advise
Dr. R.
prior
to, or on the day that it is scheduled. If you do not do so, there will
be no possibility
of making up any missed work or of being excused from any assignments,
activities or the material presented. Notifying Dr. R. can be done
by calling: 925-969-4216 or leaving a message with the department secretary
(925-969-4231) or sending an e-mail to Dr. R. If
you miss a cumulative total of 8 laboratories and/or lectures regardless
of the
reasons,
you may be
dropped
from the course. [College
policy provides for a student being dropped from a course if the student
misses a cumulative
total of two weeks of class/lab meetings.]
7. 
Laboratory:
The laboratory component of the course is essential to the overall
course.
A failling grade in the lab portion
will result in a failing grade for the course.
There will be experiments and activities that will be done on a group
or team basis as well as indivdually. For each experiment, you are
to prepare a pre-lab report prior to beginning a lab and a finished
report on completion
of the lab unless Dr. R. advises otherwise. You will be advised of
the specific details for each lab.
Pre-Lab reports must be prepared prior
to each scheduled lab. They must be in
the following format, and include: Title, Purpose, Procedure, Chemical
Reactions (where
appropriate) and neatly organized, labeled, blank Data Tables
with the units of measurement, eg. grams, mL, etc. and any assigned
questions. Before you begin any lab, you must
have Dr. R. initial the lab notebook page with the pre-lab report.
If you miss a lab for any reason, Dr. R. must be advised the day of
the lab or
there will be no possibility of making up the lab.
The finished, complete Lab report must be
in the following format, and must include
all pertinent information
including unknown numbers where unknowns are
part of the experiment. Finished copies of the report will be collected.
Lab Reports must be neat and legible. Significant
deductions will be made for failure to follow any of these guidelines.
Title
Purpose:
A brief statement of the experiment's objective: Answer the question...what
is your aim?
Procedure:
Include what you actually did so that someone else could repeat your
work. The directions can be an outline of the actual conduct of the experiment
in your own words. This section should be written in the past tense.
Refer to the Lab instructions but do not copy them word for word.
Chemical Reaction(s):
In experiments with chemical reactions include, Complete, Balanced
Chemical Equation(s); as many as appropriate.
Data:
All physical-chemical data used in the experiment (molecular weights,
density, etc.) Should be provided in neat, well organized Tables
of labeled experimental data with correct units and appropriate number
of
significant
figures. If tables are provided in the Lab text, they can be
appended. Raw data & observations should be included in this
section.
Calculations:
Show how the numerical data was handled (i.e. the general mathematics):
algorithms (formulas and equations), unit factor method, etc.and include
one example. Do not include calculations for all trials, but do show
average(s) and average deviation(s) for multi-trial experiments as
required. Be as
neat and concise as possible.
Results and Conclusions:
Re-state in one or two short sentences the results and your conclusions
versus the intended purpose of the experiment. Use tables if appropriate.
Questions:
Answer any pre-lab and/or post-lab assigned questions.
___________________________________________________________________________________________________________________________
Safety:
Laboratory safety is of the utmost importance to your well being and
to your lab mates. Chemical exposure must be minimized through good
lab practices.
All wastes must be properly disposed of. Eye protection must be worn
at all
times. No one can work in the lab without an instructor being present.
Only scheduled experiments are allowed. Bare feet, food, drink, eating,
and conduct
which places anyone at risk are unacceptable. Violation
of safety standards can result in being dropped from the course.
Internet use and related:
The course will employ the Internet and Information Technologies in
a variety of ways. This is NOT a course which teaches the Internet.
The course
is
designed to use the Internet with its wealth of resources as a transparent
tool to
teach chemistry. Combined with good study practices, it will help you,
the student,
to better and more easily understand concepts and to make your learning
experience broader and more successful.
Students are not required to have a computer or off campus access
to a computer.
Free e-mail accounts are available. Each student MUST have
their own e-mail account for class communication.
There will be no charges for the use of the Internet, computers or
course related software.
The course will employ the Internet and Information Technologies in
a variety of ways. The class will need the latest version of a Net
browser
for the
Internet as well as other computer programs. All of these programs
will be free for student use. (See Web Materials for a listing.) Since
it is realized
that not every student has a computer or off-campus access to a computer,
computer related assignments are devised and time budgeted so that
these assignments can be done while on the DVC campus by accessing
the Internet
from the Physical Science building's computers or other computers on
the DVC campus that are available to DVC students.
Students are expected to visit regularly the
course Homepage, particularly the calendar. The Homepage is
the main tool for communicating information to the class. It includes
all information
on
the course in
addition to
providing Internet links to many useful Web sites and materials for
the course. The Homepage is a living course document. Information
will be added
as the course proceeds and past information will be archived.
If you do not already have e-mail, consult the Web Resource information
linked from the Homepage for information on how to obtain your free
e-mail account. Select a provider: Yahoo, Hotmail, G-mail, etc. and
follow their
on-line instructions.
