Grading

A total of 1000 points are possible as indicated below:

  • Final, 250 points
  • Exams (3, 100 points each), 300 points
  • Lab Experiments (normalized total), 250 points
  • Knewton Homework (normalized total), 100 points
  • Online Quizzes (normalized total), 100 points

Course grades* will be assigned according to the following breakdown:

A 88.0-100%        B 76.0-87.9%       C 60.0-75.9%       D 50.0-59.9%       F less than 50%

*LACC does not have a +/– grading system.  Only A, B, C, D, F, I**, W, P/NP will be used.  I do not curve grade.

**Incomplete academic work for unforeseeable emergency and justifiable reasons at the end of the term may result in an “I” symbol being entered in a student’s record.  The “I” must be made up no later than one year following the end of the term in which it was assigned.  The complete policies can be found here.  Further more, the following will be applied.  You must currently be passing the course for an incomplete.  You must satisfactorily complete 17 out of the 18 lab assignments.  A score of “0” will be recorded for the remaining experiment and can not be made up.  Any Canvas assignments you do not complete on time will have a score of “0” and the deadline will not be extended.  You must have completed 2 out of the 3 exams, and you’ll be exempt from the 3rd. The two exams will be normalized to 150 points each instead of 100. The final must be taken within a year and a letter grade will be recorded after its completion.

Course Description: This is an introductory chemistry 5-unit course with laboratory, emphasizing fundamental principles of inorganic and physical chemistry, nomenclature of inorganic compounds, ionic and covalent bonding, problem solving, gas laws, and solutions.  It covers atomic structure, nomenclature, bonding, molecular geometry, chemical reactions, stoichiometry, states of matter and related forces, gas laws, solution chemistry, quantum theory, periodic properties, colligative properties, and acid base concepts.  This course serves as preparation for Chemistry 101, and meets the IGETC and CSU general education requirements for physical science with laboratory. The course is designed primarily for students who have had little or no chemistry training.  Attendance for both lecture and lab is mandatory. 

Student Learning Outcome: By the end of this course, you will be able to (1) interpret, analyze, and solve qualitative and quantitative problems appropriate to the course content; (2) work independently in the laboratory and perform laboratory skills and techniques exhibited in introductory chemistry laboratory.

Information for Students with Disabilities: Students with a verified disability who may need authorized accommodation(s) for this class are encouraged to notify the instructor and the Office of Special Services (SSV 100, 323-953-4000, ext. 2270) as soon as possible.  All information will remain confidential.

Financial Aid:  If you need help paying for books and other college expenses, call the Financial Aid Office at (323) 953-4000 ext 2010.

Academic Integrity: All students at LACC are expected to follow the rules of ethical conduct stated in the Student Policies section of the Schedule of Classes.  The complete schedule of classes in PDF format is found here.

Cheating will not be tolerated!  Cheating includes, but is not limited to, copying on exams, plagiarism, faking or falsifying experimental data, etc.  Plagiarism is the act of copying another’s written work and submitting it as your own.  Examples of plagiarism include copying another’s lab report, data, and published work.  Such actions (which are often illegal in the “real world”) may result in suspension or dismissal from the course and the college.  Per LACCD Board Rule 9803.28, violations of academic integrity include but are not limited to, the following actions: cheating on an exam, plagiarism, working together on an assignment, paper or project when the instructor has specifically stated students should not do so, submitting the same term paper to more than one instructor, or allowing another individual to assume one’s identity for the purpose of enhancing one’s grade.  If one students helps another student cheats, both will receive a score of “0” for that assignment.

Drop Date Information!  The deadline to drop without a “W” is Wednesday, June 14.   Dropping after will result in a “W” on your transcript.  The deadline to drop with a “W” is Saturday, July 8.  As of July 1, 2012 students now have only 3 attempts to pass a class. If a student gets a “W” or grade of “D”, “F”, “I”, or “NP” in a class, that will count as an attempt. A student’s past record of course attempts district wide will also be considered. You should carefully consider if you could reasonably manage this course with the other factors in your life (e.g. work, family, course load).  If you think you will not be able to complete this course with a C or better, drop by the stated deadline.  If you have any questions, please don’t hesitate to talk to me.  You may also see a counselor in the Counseling Center in AD 108.  After the drop deadline, a letter grade will be assigned.

You will be excluded from the course for any one of the following:  If you missed the first meeting of class, if you are absent more hours than the number of hours the class meets per week, or if you do not enroll in Mastering Chemistry.  However, you should not assume that the instructor will drop you.  It is your responsibility to formally withdraw from the class through Admissions and Records should you decide you no longer wish to be enrolled, otherwise you will receive an “F” in the course. If you are absent, it is your responsibility to make sure work is handed in on time and to find out what you missed in class.

Computer Resources: The Chemistry and Earth Sciences Department has a computer classroom located in SCI-316.  The classroom is normally open 8:00 AM – 10:00 PM Monday-Thursday.  If the room is locked, you can ask one of the faculty or lab technicians to open it for you.  This classroom can be reserved for class meetings by department faculty.  If the classroom is unavailable, the all-campus computer lab for student use is located on the second floor of the Martin Luther King Library and is available during the library’s normal business hours.  Please contact ext. 2396 for more information about the all-campus lab.  For information about computer access, including information regarding computer login, email accounts and wireless access, please go here

Policy on Cell Phones and other Electronic Devices:  The use of cell phones or any other electronic devices for any purpose, including smart phone calculator apps, on exams/quizzes is prohibited.  All phones are to be turned off during exams and stored.  Students caught using phones during exam may be subject to receiving a score of “0” on the exam/quiz and referral for further disciplinary action.

Description of Coursework

Final and Exams: Three exams and one cumulative final* will be given and no scores will be dropped.  The exam dates are listed in the attached schedule.  Each exam starts at the beginning of lab and if you are late to an exam, you will have the remainder of that time to complete your exam.  If you need to make-up an exam due to an emergency, a penalty of 20% (per day-weekend counts) will be assessed for the first exam taken late, and a larger penalty (40% per day) for any additional exams taken late.  Send me an email and I will tell you the date, time, and location of your make-up exam.  Once an exam has been returned and reviewed (2-7 days), there will be no more make-up exams.  The final exam date and time is listed in the schedule.  Everyone is required to take the final examination.  Failure to take the final will result in an automatic fail for this course, regardless of your grade prior to the final.

*The final exam will not be returned to you.  It is LACC’s property.  Your scores will be posted in Canvas.

Laboratory work: The laboratory component is designed to give you hands-on experience with some of the concepts learned in lecture.  Completion of the laboratory work is mandatory!  Thus, you must satisfactorily complete 17 out of the 18 lab assignments in order to achieve a grade of a “C” or higher in the course.   Completing a lab consists of performing the experiment AND handing in the lab report.  There will be no makeup labs, plan to attend every class session.  All lab work must be done individually.  The due date is listed in the attached schedule.  There is a 2-point penalty for each day that your report is late (weekend counts).  After a report has been graded and returned, you will only receive one point for that assignment, but it counts as being completed.  Multi-page report must be stapled and 2 points will be deducted if it is not.  No points will be credited to one student for lab work completed by another student; that is cheating. 

Safety goggles are to be worn by all students in the laboratory at all times.  Students who repeatedly are found not wearing goggles (to protect their eyes) will be subject to removal from the laboratory for that entire period.

You are responsible for all of the equipment in your locker. You will lose two points for each equipment you break or lose. It is best not to share equipment, and if you absolutely must share, be sure to return any shared equipment to your locker before you leave for the day.  Make sure you have put away all equipment and locked your drawer before leaving.

All students are required to keep a lab notebook. The notebook must have carbonless duplicates. You are required to prepare your notebook for data collection prior to coming to class. You will record all data directly in your notebook and you will turn in the carbon copies of your data sheets. Notebook policies are described in more detail here.

You are responsible for printing out your experiments prior to coming to lab.  I will not print them for you.

For each minute you stay after lab is over (at 1:30 pm), you will lose two points. Please set a timer so that you have enough time to clean up. Everyone is responsible for cleaning up the lab, 10 points will be deducted if you don’t.

Knewton: Homework is graded through the Knewton web-based program. The Knewton assignments include interactive tutorial assignments and is adaptive. Expect to spend an average of 45 minutes per assignment. More like “all day,” according to most of my students. No late work will be accepted. There is a correlation between doing problems, understanding the course material, and doing well on exams.  The more problems you make an honest effort at completing, better are your chances of doing well on the exams.  The point of doing Knewton is to improve your understanding of the material, not to practice for exams.  Exam problems do not necessarily look exactly like homework problems.  However, if you truly understand the material, then you should be able to reason through exam problems that look different from homework problems.  

Enrollment in Canvas is MANDATORY!  I do not use eTudes, Canvas, Blackboard, or Moodle.  This program serves as my course management system.  You will not have any recorded scores until you enroll in Canvas.  Graded and returned work are your responsibility.  If you continue to not be enrolled in Canvas, a grade of “F” will be assigned.

Online Self-Quizzes. There are three non-timed online quizzes (and one graded survey) in Canvas. You may take the quiz any time before the due date.  Only two attempts are allowed.  No late work will be accepted.

“Natural disasters” are not excuses for not completing computerized assignments.

Study Guides for Exams and Extra Credit:  There are none, please don’t ask.  There are old exams & quizzes are under the “Exams” tab. 

Miscellaneous: Please don’t ask for an extension on any assignments. The last day to turn in late work is right before the start of your final. You will probably receive 1 point for the late work. See the policy for each category. The last day to pick up papers is the day of the final. Anything left behind will be discarded.
