You are welcome to stop by my office anytime that I am there to ask questions. You can also schedule a specific time to meet with me.

If you are encountering problems with the work involved with this class, please call or e-mail me to setup an appointment as early as possible. There are many resources at Kirkwood (academic, financial, and mental health) available to help you, and I will be happy to assist you in accessing them and creating a plan for your academic success.

Attendance Policy: Successful completion of this course requires daily attendance. If you are unable to make a class please contact me so that arrangements can be made for you to make up the class material.

Learning Environment Expectations: The classroom and laboratory conditions will be conducive to teaching and student learning. To promote and maintain that environment, all pagers, cellular phones, and other autonomous means of communication shall be deactivated during instructional periods. RINGING

1 OF CELL PHONES DURING CLASS WILL RESULT IN POINTS DEDUCTED FROM YOUR CLASS ROOM PARTICPATION AND PROFESSIONAL CONDUCT GRADE. Participants are expected to come to class prepared to actively participate in class.

Productive Classroom Learning Environment:

We believe that the best learning takes place in an environment where faculty and students exhibit trust and mutual respect.

Students promote trust by preparing honest and thoughtful work, and by expecting evaluation based on performance. Faculty promote trust by setting clear guidelines for assignments and evaluations, honest feedback, and by assigning bias-free grades.

Students show respect by being prepared and attending class on time, by paying attention, contributing to discussions, listening respectfully to others’ points of view, meeting deadlines, and by striving for their best performance. Faculty show respect by their timeliness and preparedness, by taking students seriously, by valuing their goals and aspirations, and by providing honest feedback.

In a productive learning environment, faculty and students work cooperatively, recognize and respect differences, model the values of character and citizenship, and become lifelong learners.

Class Attendance Policy and College Sponsored Activities:

Class Attendance Policy: Learning is central to our work at Kirkwood Community College. Faculty design educational experiences to facilitate learning, and students learn by engaging in those experiences. Attendance and engagement in all scheduled classes is regarded as integral to learning and is expected of all students. Kirkwood faculty members identify expectations for learning and attendance in their course syllabi. Students are accountable for the learning outcomes for each session, including those sessions that have been missed. Assessments of learning that occur during an absence may or may not be made up, depending on the policies of the instructor and the nature of the absence. Absences that result from participation in college sponsored activities* will be accommodated, subject to the guidelines listed below. For all other absences, authorization of an excuse is the province of the individual faculty member and subject to the standard appeal process.

College Sponsored Activities: Students involved in activities where they are required to represent the college, i.e. college- sponsored activities, must give written notice to the faculty member at least one week in advance of the absence unless last minute schedule changes make this notice impossible. If regular season athletic schedules have been developed, student participants must present written notice of anticipated absences within the first week of the semester. Failure to provide timely written notice may result in loss of this opportunity. Faculty shall accord students the opportunity to independently make up course work or work of equal value, for the day(s) the event was scheduled and to take a scheduled exam at an alternate

2 time. The faculty member shall determine alternate exam times and due dates for missed coursework. These assigned dates may be prior to the date of the absence. Organizers (coaches, faculty and staff) of college sponsored activities shall 1) assist students in planning class schedules to minimize the number of absences; 2) inform students of their responsibilities as described above; and 3) provide written communications to faculty announcing and verifying the need for student class absences. Written notices should be provided at the beginning of the semester if the schedule is known, or as soon as possible after the need for a student absence is determined. * College sponsored activities (excluding practices) include such events as athletic competitions, student academic competitions and conferences, musical and drama performances, and class field trips. Questions on whether an activity is a college-sponsored event for purposes of this policy should be directed to the Vice-President of Instruction. If anticipated absences for a semester appear to be extraordinarily numerous or difficult to accommodate, a faculty member may appeal the need for the full accommodation to the VP of Instruction.

Plagiarism Policy: According to Webster, to plagiarize is “to steal or pass off the ideas or words of another as one’s own…to use created productions without crediting the source…to commit literary theft…to present as new and original an idea or product derived from an existing source.”

Kirkwood Students are responsible for authenticating any assignment submitted to an instructor. If asked, you must be able to produce proof that the assignment you submit is actually your own work. Therefore, we recommend that you engage in a verifiable working process on assignments. Keep copies of all drafts of your work, make photocopies of research materials, write summaries of research materials, hang onto Writing Center receipts, keep logs or journals of your work on assignments and papers, learn to save drafts or versions of assignments under individual file names on computer or diskette, etc.

The inability to authenticate your work, should an instructor request it, is a sufficient ground for failing the assignment.

In addition to requiring a student to authenticate his/her work, Kirkwood Community College instructors may employ various other means of ascertaining authenticity – such as engaging in Internet searches, creating quizzes based on student work, requiring students to explain their work and/or process orally, etc.

Americans with Disabilities Act: Students with disabilities who need accommodations to achieve course objectives should file an accommodation application with Learning Services, Linn Hall 2063 and provide a written plan of accommodation to your instructor prior to the accommodation being provided.

1. We do not do the UTC experiment, but the students do a similar experiment from PASCO Assessment of Student Learning: Student learning will be assessed via exams, homework, class room participation, and lab reports.

Student Evaluation:

Final Exam – A comprehensive final exam totaling 20% of your final grade will be administered during finals week.

Unit Exams - Exams will be given after every 3 or 4 chapters totaling 40% of your final grade. Missed exams must be made up on or before the next class period. In a rare situation where the exam can not be made up in that time period, the student will need to make up the exam during the final exam week and this exam will be different than that taken by the rest of the class. All exams will be cumulative.

Class Room Participation and Professional Conduct - 10% of your final grade

Points will be added to classroom participation and professional conduct grade based on the following: 1. Arrival at class by 8 am (50 % of class participation grade) 2. Performing in class problems 3. Helping lab partner or other lab groups. 4. Helping other classmates.

Points will be deducted from the classroom participation and professional conduct grade for the following: 1. Complaints during class time. If you have an issue with the class, talk with the instructor outside of class (Your classroom participation will be a 0 for each time you complain in class). 2. Ringing of cell phones in class. 3. Disrupting the class. 4. Leaving class early or not arriving back to class by 9:00, after the 8:00 break. 5. Not cleaning up workspace at the end of the class.

Labs - Labs will be worth 30% of your final grade. Labs will be done in groups of up to four people. You will lose a point per minute late if you are late to a lab. THERE WILL BE NO MAKE UP LABS!!!

Grading Scale: A letter grade will be computed using the following grading scale.

A = 94 - 100 A- = 90 – 93.99 B+ = 87 – 89.99 B = 83 – 86.99 B- = 80 – 82.99 C+ = 77 – 79.99 C = 73 – 76.99 C- = 70 – 72.99 D+ = 67 - 69.99 D = 63 – 66.99 D- = 60 – 62.99

11 F = 00.0 - 59.9 FW = Failure to withdraw FW has the same negative affect on your grade point as a F. The FW grade indicates a student failed the course, had not attended after the 60% point of the course, and did not withdraw by the withdraw deadline. That letter grade will then be adjusted according to the attendance policy to compute the final grade for the course.

Late Policy: No late work will be accepted!

Make up Policy: THERE WILL BE NO MAKE UP LABS!!! Missed exams must be made up on or before the next class period. In a rare situation where the exam can not be made up in that time period, the student will need to make up the exam during the final exam week and this exam will be different than that taken by the rest of the class.

Drop Date: Students dropping a class during the first two weeks of a term may receive a full or partial tuition refund. Details of the refund schedule are available from Enrollment Services in 216 Kirkwood Hall. For detailed discussion of drop dates and policies, please read the student handbook. The last day to drop this course is April 12.
