A final grade of "C" or better should indicate the student can successfully apply the principles and techniques taught in this course in subsequent courses and can, therefore, perform satisfactorily without notes or instructor assistance. Course activities will also measure critical thinking skills. These methods may include, but are not limited to the following: 1. Reading through the laboratory experiment, completing Blackboard assessments and writing a purpose before coming to class as to why the student is conducting the scheduled experiment. 2. While working on an experiment, writing accurate and precise observations, labeled diagrams and procedures into your notebook. 3. Successful and accurate completion of laboratory packet pages. 4. Summarizing results including writing detailed answers to the final four questions; see bottom of page 8. 5. Completing objective unit examinations proctored in class and/or online that reflect the material covered in that unit. The examinations will ask both quantitative and qualitative questions. 6. Successful completion of a comprehensive final exam. An activity and its due date will be posted to an online calendar, and at my discretion announced by email and/or displayed under assessments in Blackboard. It is therefore crucial that you attend all class sessions, frequent your email account and Blackboard account. The points earned for each assessment within each activity category will count toward the final course grade. The activity categories and their weighted percentages are as follows: Course Activity Percent of Final Grade Laboratory Exercises* 80% Final 20% Overall Grade Calculation [(your total exercise scores)/(total exercise pts)*0.80] + [(your Exam 2 score)/(total Exam 2 pts)*0.20] * Good Laboratory Practice (GLP) violations You will receive a minimum of 5% overall grade reduction per violation per experiment and/or zero credit for your work if you violate any GLP; see GLPs page 7. Overall Grade Calculation: A student s overall grade will be derived from a culmination of points received during the semester and then applied to the grading system guidelines. A 90% B 80% C 70% D 60% F < 60% NOTE: Blackboard does not calculate your overall grade but will show points earned on assessments. We can review your grade at anytime but you must have a completed grade sheet before we have our discussion 4
A warning about turning activities in late: Any course activity not submitted when asked to do so by the instructor and/or when prompted to so by Blackboard will be receive a grade reduction; one-percent grade reduction per every one-minute late. Any mailed exercise will received 10% grade reduction per every day past-due the submission postmark date. Attendance/Performance: Students in my courses make better grades when they regularly attend class and/or participate online. When roll is called and you are not present you will be marked absent; no excuses and no exceptions. A student with two or more absences will be considered to be in nonattendance. It is a student's responsibility to withdraw if he/she is unable to continue in attendance but a student in nonattendance meaning lack of regular and consistent attendance (for example: two unexcused absences and/or truancies, and/or two missed activities and/or one or more weeks of nonparticipation in class and/or online occurrences) in or before the "Last Day to Withdraw with a "W" on Student's Transcript" date may be dropped by the professor. By district policy, you may be dropped from class if you miss the first day; see the calendar on page 11 in this syllabus for important dates. Absences: Students are responsible for ALL work, announcements, assignments and handouts they have missed during their absence. There are two types of absences excused and unexcused. Excused absence (your limit is one). The absence will be marked excused if you inform me prior or on the day of your absence you will not be participating in class. Only under the most extenuating circumstances will I allow for more than one excused absence but I am not obligated to do so. Unexcused absence. You are responsible for attending class, being time on task and for accessing and completing all activities given within a specific availability period and before their due date. Any other absence or truancy late arrival or early exit from class and/or not scheduling a meeting with me to grade your grade sheet & portfolio will be considered as an unexcused absence. Failure to complete any online assignment during its availability period will be considered an unexcused absence and you may be automatically denied access to your Blackboard account. If you are locked out of your Blackboard account, contact your professor immediately at dgergens@sdccd.edu. Assistance during an absence: If you have or intend to miss class, contact me by phone, fax, or email so we can make arrangements to keep you informed on lecture topics, handouts and assignments. Failure to make arrangements prior to or during your absence will result in forfeiting the right for extra assistance. Making-up a missing activity: An arrangement to make-up a missing activity only can be made for an excused absence. However, upon your immediate return to class, failure to arrange to complete the missing work on time will result in the student forfeiting the right for a make-up. A missing activity will receive zero credit. Laboratory Experiments: There is no substitute for coming prepared to work safely in the laboratory. Before coming to class, please read through the experiment, procedures, and pre- and post-laboratory questions and complete all prelaboratory activities and computer assisted instruction following the directions on the online calendar. We will be completing 13 laboratory experiments. Laboratory report due dates will be posted to an online calendar, and at my discretion announced in class and/or by email, and/or displayed under assessments in Blackboard. It is therefore crucial that you attend all class sessions, check the online calendar as well as frequent your email and Blackboard account. Each completed experiment will be evaluated in terms of your laboratory notebook record keeping and neatness, data and calculations, critical discussion of results and answers to pre- and post-laboratory questions. Each day in lab the student's notebook will be checked and initialized by your instructor. 5
Laboratory Activities: The goal of these activities will be to prepare you to work safely in the laboratory for an upcoming experiment, review recent laboratory work and to check one's performance. Multiple methods of teaching and measuring performance and understanding will be given in the form of in- and out-of-class exercises and/or assessments (including online) and may include a multimedia project. In general, a laboratory activity will cover safeties and recent lecture notes, textbook and handout material, but may also cover lecture assignments, and review questions from previous experiments. A laboratory activity may include, but is not limited to, the following: a problem set, use of instructor created online materials for computer assisted instruction, an online exercise/assessment, announced and/or unannounced quiz, exams, oral, written, and/or multimedia presentation, outside reading and/or written essay related to the course objectives, and effective preparation and participation in laboratory experimentation. A laboratory activity and its due date will be posted to an online calendar, and at my discretion may be announced in class and/or by email, and/or displayed under assessments in Blackboard. It is therefore crucial that you attend all class sessions, check the online calendar as well as frequent your email and Blackboard account. We will be completing over 13 laboratory exercises. Unless announced otherwise, laboratory reports are due seven day from the last scheduled day for experimental work. See your attached syllabus calendar for starting dates for each experiment. Final: The final will be given on material discussed up until the day of the check-out from your locker in the laboratory. The final may include, but is not limited to, scantron-graded questions (multiple choice, matching, true/false), short essay, fill in the blank, and mathematical computations covered in the laboratory. Cooperative Learning: Active, not passive learning is essential in this course. Although all students are expected to have completed their laboratory activities individually, work together in study groups. Working in groups is especially recommended for preparing for examinations. Asking questions in class and in the professor's office is an important part in making the learning experience more participatory. Safe questions students should ask their instructors are: "Where do you feel most students have difficulties in understanding this material?" "From your experience, what are common mistakes students make in solving this type of problem?" "What do you find most interesting or intriguing about the material just presented to us?" "What questions should we be asking that we are not?" Asking questions from your perspective: Get the benefit of a further explanation or an interesting discussion by asking questions in class. ALWAYS ASK QUESTIONS if you do not understand and when given the opportunity to do so. Since the material presented in this course is cumulative, the questions students ask provide their professors with information about how carefully the students have been listening, possible areas of confusion, and, most importantly, how a professor might adjust their style of teaching to meet your needs. When you ask questions you become a participant rather than a spectator in an academic dialogue. Library Resources & Services - San Diego Mesa College LRC: Use IT!

General Overview of Laboratory Work Come to class prepared for laboratory. Please read through the assignment, procedures, and pre- and postlaboratory questions before coming to class. Please also check your Blackboard account for additional directions. Before coming to class and while in the laboratory, record and document all laboratory records parts 1 and 2 onto notebook paper. The notebook paper is to be neatly stapled to the first data page of the laboratory packet for each experiment. Before leaving the laboratory, have your instructor initialize and date your notebook pages. Part 3 is completed outside of laboratory and is to be stapled behind your laboratory packet pages. PART 1 - Out of Class Preparation and Thoughtful Intent Before beginning an experiment, check your Blackboard account of additional directions, and for each experiment you should have written into your laboratory notebook a title page for the experiment followed by a purpose. A. Title: Write your name, title of the experiment and date at the top of notebook page. B. Purpose: Write a purpose in third person passive voice underneath the title. The purpose should be an overview of the experiment and the reason for doing it. It is always given in relation to the experimental work (to synthesize, to purify, to measure, to compare, etc.). Include all pertinent chemical equations. Perhaps, begin your purpose with, In this experiment, C. Safeties: Read through the entire experiment and self reflex on special safety considerations needed in the experiment. Safety considerations should be written following your purpose section above. PART 2 - In Class Experimentation During laboratory work, each student should write into his/her laboratory packet diagrams of set-ups and written procedures. C. Procedure: Begin your procedure by saying, "Review all safeties...." While you are conducting the experiment, write experimental procedures and observations in such manner anyone could repeat the experiment. For example, when recording your procedures and observations ask yourself the following question, "Could a group of high school students repeat any given part of my experiment based on what I have written into my laboratory notebook?" Hopefully, your response will be "yes" if I ask you this question. D. Label Diagrams: Draw and label all laboratory set-ups. PART 3 - Critical Analysis of Results and Discussion After completing the experiment, each student will complete the following. E. Data, Calculations, Graphs and Questions: Refer to pages from the manual for further directions F. Write a brief conclusion and answer these final four questions: 1) What did I do in this activity; 2) What did I see in this activity; 3) What did I learn in this activity; and 4) What would I like to do next. Unless announced otherwise, a completed experiment parts 1, 2 and 3 is due seven days from the last scheduled day for experimental work at the beginning of the laboratory period. 8
Academic Policies Academic Policies: Please read through the most recent college catalog for details regarding the following: Accommodation of Disability: Students with disabilities who may need academic accommodations should schedule an appointment with their professor to discuss options immediately during the first two weeks of class. Classroom Behavior and Student Code of Conduct: Students are expected to respect and obey standards of student conduct while in class and on the campus. The student Code of Conduct, disciplinary procedure, and student due process (Policy 3100, 3100.1 and 3100.2) can be found in the current college catalog in the section Academic Information and Regulations, and at the office of the Dean of Student Affairs (Student Services Center I4-408). Charges of misconduct and disciplinary sanctions may be imposed upon students who violate these standards of conduct or provisions of college regulations.. Contentious behavior and the inability to follow directions and/or directives. Contentious behavior and the inability to follow directions and/or directives as explained in this syllabus (i.e., Attendance Policy, Student Code of Conduct) during course activities will not be tolerated. If a student shows contentious behavior toward fellow students and/or their professor or is unable to follow directions and/or directives during any given course activity, zero credit will be given for that course activity. Academic Honesty Policy Students' conduct, rights, and responsibilities are governed and supported by District Policy 3100. This policy will be absolutely upheld in this course and is available for review in the Vice President, Student Services and the Dean of Student Affairs offices. Any lecture or laboratory material lab reports, exams, homework, etc. prepared in a manner that is in violation with Policy 3100 will NOT be graded or counted. Add, Drop and Withdrawal Policy: It is the student's responsibility to add, drop and withdrawal from classes before the deadlines stated in the class schedule. If you stop attending class and you fail to withdraw by the deadline stated in the class schedule, a final grade must be assigned to you. Eating, Smoking, or Drinking is not permitted in the classroom or laboratory. This syllabus is intended to help the student plan his/her work in this course and is no way considered to be a contract. It is subject to change at any time by the professor should a change be in the best interest of the class. Students who withdraw and/or are in nonattendance will have their materials discarded.
