General Syllabus
I.
BASIC COURSE INFORMATION:
A. Course Description:
One-hour credit. Basic laboratory experiments supporting theoretical principles presented in CHEM
1311; introduction of the scientific method, experimental design, data collection and analysis, and
preparation of laboratory reports. Co-requisite: CHEM 1411 lecture. Lab fee.
B. Intended Audience:
1. This course designated for science majors, or for students with a major, which requires a
four credit hour chemistry course beyond introductory chemistry.
2. Note: Do not confuse this course with CHEM 1305, Introduction to Chemistry. Both are
“freshman” chemistry courses. Verify with your advisor that this is the appropriate course
for your degree plan.

6. For exams: (a) “Scantron” forms and (b) #2 pencil
B. Course Policies – This course conforms to the policies of Angelina College as stated in the
Angelina College Handbook.
1. Academic Assistance – If you have a disability (as cited in Section 504 of the
Rehabilitation Act of 1973 or Title II of the Americans with Disabilities Act of 1990) that
may affect your participation in this class, you should see Karen Bowser, Room 208 of
the Student Center. At a post-secondary institution, you must self-identify as a person
with a disability; Ms. Bowser will assist you with the necessary information to do so. To
report any complaints of discrimination related to disability, you should contact Dr.
Patricia McKenzie, Administration Building, Room 105 or 936-633-5201.
2. Attendance – Attendance is required as per Angelina College Policy and will be
recorded every day. Any student with three (3) consecutive absences of four (4)
cumulative absences may be dropped from the class. Records will be turned in to the
academic dean at the end of the semester. Do not assume that non-attendance in class
will always result in an instructor drop. You must officially drop a class or risk receiving
an F. This is official Angelina College Policy.

EVALUATION AND GRADING:
A. Grading Criteria
Course grades are assigned in light of a numerically-determined course score (see subsection "B" for
details), according to the following table:
COURSE SCORE

A
80–89
B
70–79
C
60–69
D

B. Overall Course (CHEM 1411/CHEM 1412) Score will be determined according to the following
percentages:
1. 25% from the Final Exam; 45% from the average of Exams 1,2, and 3; 25% from the
Laboratory score (see subsection "C" for details); and 5% from the assigned on-line
homework ("OWL")
2. The four components are weighted according to the equation:
Course Score = 0.25 (Final Exam Score) × 0.45 (average of all midterm exams)
× 0.25 (Laboratory Score) × 0.05 (OWL on-line homework score)
C. Overall Laboratory Score (a component of the overall Course Score)
1. 80% from the average score of the assigned laboratory experiments (see section "D" for
details); 20% from the written laboratory final exam.
2. The two components are weighted according to the equation:
Laboratory Score = 0.80 (average of individual experiments score)
× 0.20 (laboratory Final Exam Score)
D. Scoring of Individual Experiments
1. A student must be physically present during the laboratory period, and actively
participate in the experiment, to receive credit for any of the scored components, which
follow.
2. 30% from the on-line pre-lab quiz; 70% from the experiment Report, demonstrated in-lab
performance/participation, and post-lab questions.
3. The two components (pre-lab quiz and "Report') are weighted according to the equation:
Individual Experiment Score = 0.30 (on-line quiz score)
× 0.70 (report & participation score)
4. NOTE: if a particular lab experiment is not physically attended, then the total score for
that experiment is set to zero. The net result is that the on-line quiz score, the report and
participation score, and the post-lab questions score are scored at zero: any scores or
materials provided are disregarded.
5. NOTE: if you are asked to leave the lab, that lab will be scored a zero, and it will NOT be
available as a candidate for a "dropped" lab. The zero will be averaged into your final
laboratory score.
6. NOTE: on occasion, and with permission of each of the professors involved, you may be
allowed to attended a different lab section, rather than miss an experiment altogether.
This will be allowed a maximum of two times per semester. Note that both professors
must agree AND be notified via email, which serves as written documentation of the
change.
E. Make-up Labs
1. For labs without experiments, a Worksheet will count as the lab grade.
2. There will be NO make-up labs; however, one individual experiment grade will be
dropped.
3. Missed lab counts as a “zero.”
4. If you are asked to leave a lab, that lab will necessarily be scored as a zero, and that
score will not be eligible to serve as the "dropped" experiment grade.
5. No student will receive credit for a lab, which he/she did not both attend and participate.
The instructor may modify the provisions of the syllabus to meet individual class needs by informing the class in
advance as to the changes being made.
