V. Academic Integrity:

Students and employees at Oakton Community College are required to demonstrate academic integrity and follow Oakton’s Code of Academic Conduct. This

code prohibits:

• cheating,

• plagiarism (turning in work not written by you, or lacking proper citation),

• falsification and fabrication (lying or distorting the truth),

• helping others to cheat,

• unauthorized changes on official documents,

• pretending to be someone else or having someone else pretend to be you,

• making or accepting bribes, special favors, or threats, and

• any other behavior that violates academic integrity.

There are serious consequences to violations of the academic integrity policy. Oakton’s policies and procedures provide students a fair hearing if a complaint is made against you. If you are found to have violated the policy, the minimum penalty is failure on the assignment, and a disciplinary record will be established and kept on file in the office of the Vice President for Student Affairs for a period of 3 years.

Details of the Code of Academic Conduct can be found in the Student Handbook.

Each laboratory will include a short lecture explaining the day’s particular experiment, performing the experiment in small groups, and answering questions included in the lab handout.

VIII. Course Practices Required:

Homework

There will be “offline” and “online” homework. Offline homework is book homework. The homework is assigned via the class website (see below). This homework is frequently reviewed in class, but in general is not collected (there may be exceptions). Online homework is homework assigned via (see below). This homework is graded, and is not in general reviewed in class. There will be 40 total points for the online homework, and half of those points, rounded up to the nearest half point, will be added to your total grade points.

Exams and Pop Quizzes

There will be four regular exams and two pop quizzes during the semester. Everyone takes the exams and pop quizzes at the same time; there are no makeup exams or pop quizzes.

Each exam is worth 25 points. The lowest of the first three exams will be dropped. The final exam is not droppable. Use your droppable exam wisely. Your test points will be added to your total grade points.

Each pop quiz (no advance notice given) is worth ten points; the lower of the two pop quizzes is dropped. Your pop quiz points will be added to your total grade points.

You may not leave the classroom during a test or a pop quiz until you have finished the test or pop quiz.

Labs

Ten labs will be performed during the semester. Each lab is worth 2 points. Everyone performs the labs at the same time; there are no makeup labs. You lab points will be added to your total grade points.

For labs requiring a lab report, if the lab report is not turned in on time, or is otherwise deemed inadequate, the lab, if physically completed, will be valued at 1 point instead of 2 points.

Class Participation

Five of your total grade points is for class participation. Class participation means coming to class, coming to class on time, not talking during lecture, and not otherwise acting in a manner disruptive to the class.

XI. Other Information:

A. If you have a documented learning, psychological, or physical disability you may be entitled to reasonable academic accommodations or services. To request accommodations or services, contact the Access and Disability Resource Center in the Learning Center. All students are expected to fulfill essential course requirements. The college will not waive any essential skill or requirement of a course or degree program.

B. Oakton Community College recognizes the broad diversity of religious beliefs of its constituencies. The college has embraced a practice of shared responsibility in the event a religious observance interferes with class work or assignments. Students who inform instructors in advance of an intended absence for a major religious observance will not be penalized. The instructor will make reasonable accommodation for students, which may include providing a make-up test, altering assignment dates, permitting a student to attend another section of the same course for a class period or similar remedies. Instructors are not responsible for teaching material again. Instructors should inform students of this practice at the beginning of the semester so that arrangements can be made accordingly. Similar consideration is accorded to faculty, staff and administrators and is provided for in their respective contracts.

C. Accommodations for learning disabilities should be requested by email during the first week of class.

Students should inform the instructor of the dates they will be missing class due to religious observances by the end of the first week of class. This should be done in writing, via email, from the student directly. Students may be required to sign a statement saying that they understand that if they do not inform the instructor of the days they will miss due to religious observance they may not (or will not, by the instructor’s choice) be allowed to make up the missed material.

D. If you are pregnant or become pregnant during the semester, you need to tell your instructor in a timely fashion, so that if accommodations are needed, they can be made.

E. PHY 221 or equivalent is a prerequisite to this course. This means that you must know many of the topics from PHY 221 to succeed in PHY 222. For example, you will need to remember the kinematic equations for constant acceleration, Newton’s Laws, the Work-Energy Theorem, the relationship between potential energy and conservative forces, the definitions and equations for linear and angular momentum, and the mathematics of vibrations and simple harmonic motion. If these topics are not familiar to you then you may want to drop this course. If you have taken PHY 221, or its equivalent, but are a bit fuzzy about the above topics, then you definitely will need to review the topics.

F. In general, please turn off all cell phones and pagers. Computer use in the classroom is for class activities only.

G. During tests, you will use a calculator provided by the school. All tests will be completed in pen only. Any phone use during tests will result in zero points. Again, you may not leave the classroom during a test.

H. I reserve the right to move any student to another seat in the classroom, no reason given, none required.

I. Last day to withdraw and have the course dropped from your record is September 18.

J. Last day to withdraw from the course with a W is October 23.

K. The college is closed on September 5, November 11, and November 24th through November 27th.
