ASSESSMENT & GRADING:

The complete listing of topics covered, textbook readings, assignments and due dates can be found on the course homepage. Course grades will be calculated as follows:

Course Component	Percentage of Grade
Exams	55 %
Quizzes & Homework	15 %
Participation	5 %
Laboratory Work	25 %

Extra credit (no more than 3% of course grade) will be offered from time to time for independent projects or completing surveys, and will be announced on the announcements page of this website.

Exams, quizzes, lab reports, or other course assignments may not be made-up, unless students can provide DOCUMENTATION of a medical illness or emergency that prohibited their participation in regular course work. 

Letter grades will be assigned according to the cutoffs below:

Letter Grade	A	B	C	D	F
Course Percentage	90.0-100%	80.0-89.9%	70.0-79.9 %	60.0-69.9 %	< 60.0%

 ______________________________________________________________________________________

• EXAMS: Three Midterm Exams (100 points each) and one comprehensive Final Exam (250 points) will be given, for a total of 550 points (55 % of total course grade). Each exam will consist of multiple choice questions (scantron needed) and free response questions. The exam questions will be closely tied to the lecture slides, iClicker questions, & quizzes. 

______________________________________________________________________________________

• HOMEWORK & QUIZZES: Homework assignments related to the daily readings will be assigned from the textbook. These problems will NOT be collected or graded, but still represent an important element of the course. As an incentive for completing the assigned problems, the reading and homework questions will be used to generate quiz questions.

• There are two types of quizzes in this course: 1) "Concept Checks" that occur at the start of EVERY lecture; and 2) Standard Quizzes that occur during lab time. Please see below for an explanation of each:

Quiz Grade	Maximum Points
Concept Checks (2 points each)	50
Standard Quizzes	Normalized to 100
Total (15 % of Course Grade)	150

 

• STANDARD QUIZZES: Announced at least two days in advance, these quizzes will consist of multiple choice AND free response questions, and will be administered during lab time. The goal of these quizzes is to prepare you for the questions and format of the exams. The quiz questions will be closely related to the lecture slides, iClicker questions, and helpful links from the course website. At the end of the course, the total points possible for the standard quizzes will be normalized to 100 points.

• CONCEPT CHECKS: At the start of EACH lecture (~25 lectures total), a multiple choice quiz question will be given. You will have 5-10 minutes to work INDIVIDUALLY and respond with your personal iClicker remote. Responses will be graded for accuracy (2 points for a correct answer).  These are called Concept Checks because they are based on the reading and lecture slides from the PREVIOUS class period. These graded questions provide incentive for reviewing the lecture material on a daily basis, and serve as a low-stakes check-in on your understanding of the material.
• Please note that Concept Checks cannot be made up in the event of an absence. If you arrive late, you will NOT be given additional time for the quiz question. 

______________________________________________________________________________________

• PARTICIPATION: For full participation credit, a maximum of 50 points (5 % of the course grade) will be awarded as follows:

•  In lecture or lab, students will sometimes be asked to work in small groups (3-5 students per group) to solve multiple choice questions requiring critical thinking, and knowledge of chemistry. Each student will then submit their answer individually. Answers will be submitted and recorded with the iClicker remote response system. These responses will not be graded for accuracy. Answering ALL of the iClicker questions for a given lecture or lab period will be worth 2 points. By responding to iClicker questions, students can receive a maximum of 50 points (which represents full credit for participation).
• You are not allowed to enter responses for another student who is absent from class--if this behavior is observed, all students involved will receive a 0 for their participation grade.

______________________________________________________________________________________

• LABORATORY WORK: Attendance in lab is REQUIRED. Laboratory work includes computer simulations and molecular modeling activities that are integral and required parts of this course. Attendance in lab is REQUIRED. 
  
• The Cabrillo College laboratory safety rules will be enforced at all times. Students who refuse to obey these rules will be asked to leave the laboratory.
• You will be completing worksheets from the required lab manual as well as handouts which I will provide throughout the course. 
• Each assignment is worth 10 points (including 1 points for safety and cleanup where applicable), and is due one class session after the completion of the corresponding material. At the end of the course, the total points possible for all of the reports will be normalized to 250 points (25 % of the course grade).
• Assignments turned in after the start of the lab period are late and will be deducted 30%. An additional 30% will be deducted each additional lab period the assignment is late. Assignments more than 3 lab sessions late will not be accepted.
• For each wet lab experiment, you must read and understand both the background information and the procedure BEFORE coming to the laboratory.
• For some experiments, you may be collecting and sharing data with a partner. HOWEVER, you must do your own calculations and formulate your own conclusions for each experiment. Please refer to the section on Academic Integrity below for more information.

STRATEGIES FOR SUCCESS:

If you are serious about being successful in this course, I highly recommend you read and adopt these study tips discussed in this link. This advice could very well apply to any course or subject you choose to learn.

Below, I've outlined some of my own thoughts on learning, as well as highlighted valuable resources we have available at Cabrillo.

• INDEPENDENT STUDY: To thoroughly learn the concepts of chemistry (or any subject for that matter), you must be an actively engaged and dedicated learner. This means you must do more than simply listen to an instructor in lecture, review lecture slides, and watch videos. To improve your independent study skills, I would encourage the following practices:
• After reading a page or paragraph in the textbook, try to explain the concept IN YOUR OWN WORDS. Science textbooks are not like fictional literature. It may sometimes be necessary to re-read, and re-re-read a section to understand the material. When you can't understand a complex sentence break it down into smaller pieces and try to understand each of the components. Ask questions about how something could be proved or tested. Reading in this way can be slow and frustrating, but it will help lead you to a deeper understanding than if you just skimmed the material. 
• Try to arrange your schedule so you can read the assigned textbook sections BEFORE coming to lecture. This way you have already been exposed to the terminology and concepts before I try to explain them as best as I can. Studying chemistry can be like learning a new language, and you need practice reading it on your own.
• After lecture, spend the time going over practice problems. Try to work through questions without reference to the lecture slides, readings, or an answer key. Only when you are stumped should you consult external materials. Remember, you are trying to train yourself to solve problems independently. That being said, group work can be a powerful component to learning and retaining new concepts.

• GROUP STUDY: You will often be asked to make study groups during lecture and lab time.  I recommend forming study groups to work outside of class time as well. Success in science and math is increased by active study and discussion with peers. Take group discussions as an opportunity to listen to how other people understand and explain concepts; this can lend new perspective. At the same time, try to offer your own explanations for difficult concepts. Trying to teach material to others can solidify your understanding or can help you pinpoint areas that you still don't entirely grasp.

To find out more, come by the MESA Study Center in the STEM Center in the 800 Building, call (831) 479-6503, or use our website shortcut: www.cabrillomesa.org.

• THE MATHEMATICS LEARNING CENTER: The Math Learning Center (MLC) is a free drop-in math tutoring service for Cabrillo College math students and students taking courses having math prerequisites. The MLC was created to help students develop an ability to tackle math problems on their own. By logging into the MLC database, students may request and receive help within minutes. Some of the ways in which students receive help are:
• clarifying and applying basic math concepts
• test taking and study skills
• understanding applications
• problem solving skills
• interpreting solutions
• organizing information
• analyzing errors
• connecting new knowledge to existing knowledge
• using resources (books, notes, calculators, Internet, computers and mobile devices)
• building confidence

When requesting help, individual tutors go to where students are studying. There is no line to wait in and students are helped in the order in which they request help. To reduce waiting time, each student is often helped with one or two problems before the tutor moves on to the next student. This gives students an opportunity to apply what they just learned to similar or new problems on their own; however, there is no limit to the number of times students may request help. Students may see how busy the MLC is by visiting the webpage: www.mlc.polyhedraldesign.com.

In addition to tutoring, students may use their Cabrillo Library Card to check out calculators, laptops*, textbooks, textbook videos, various learning software packages and a biofeedback system for managing math anxiety. These materials are available for use in the MLC. Also provided are exam review sessions and study sessions when coordinated with the instructor. To use the MLC during the semester, please visit the Center in room 1074 and register for services. For additional information about the MLC, call (831) 477-5696 or visit the website at www.cabrillo.edu/services/mlc.

• FOR DSPS ACCOMMODATIONS: As required by the Americans with Disabilities Act (ADA), accommodations are provided to insure equal opportunity for students with verified disabilities. Students needing accommodations should contact the instructor as soon as possible with documentation from the Learning Skills or DSPS offices.  For more information, please contact Disabled Student Services, Room 810, phone: (831) 479-6379, or the Learning Skills Program, Room 1073, phone: (831) 479-6220.

______________________________________________________________________________________

CONDUCT & ACADEMIC INTEGRITY: If you are late to lecture or need to leave early, please be courteous enough to do so quietly. Any unauthorized use of cell phones and computers (including emailing, texting, surfing the web, and playing games) during lecture or lab is considered disrespectful towards the instructor and other students. If phone or computer use becomes distracting to other students or to me, I will ask you to leave the classroom. 

It is your responsibility to understand what constitutes academic dishonesty in accordance with the Cabrillo College Academic Integrity Policy. If you are caught cheating or plagiarizing at any time, then your violation will be reported and you will receive an F for that assignment or assessment (0 points). If you are caught cheating or plagiarizing a second time, you will receive an F for the course.

Any smart phones or other electronic devices (other than calculators) shall not be visible during any quiz or test. Failure to have devices out of sight will forfeit your grade for that assessment, and may lead to disciplinary action.
