HOMEWORK POLICY
PHILOSOPHY
I assign quite a bit of homework. It is my strong belief that practice at any particular thing is necessary to improve one’s skills. As a result, many homework problems help you to practice and improve your physics skills. Your homework is 15% of your total grade, but it should be the easiest 15%. If you make a real effort at the homework, I will give you full credit irrespective of whether your answer is 100% correct. That being said, a “real effort” is not considered to copy down the answers for the odd numbered problems in the back of the book. Nor is it considered a “real effort” to do the homework well after it is due. Each homework assignment is a tool to 1) generate inclass questions for the next class period and 2) to give you practice before the next test.
LENGTH OF ASSIGNMENTS
I expect you to get practice, I do not expect you to pound your head against the wall. Only work on each assignment for a maximum of 4 hours. This is a four hour class, and thus you should expect to spend at least 8 hours on this class outside of class per week (two hours for each in-class hour). If it is taking you longer than that, either I made too long an assignment, or you do not “get it” and you aren’t getting good practice anyway. STOP AFTER FOUR HOURS. Write on your homework paper that you worked for four hours and only got so far. I will be able to tell if you really worked hard or not. The additional class time will be expected to be spent on the lab reports and preparing for tests and quizzes.
HOMEWORK ASSESSMENT
I will expect each of you to keep your homework assignments organized in a notebook. I do not care if it is a simple spiral notebook, a three ring binder, or something else. I will collect this homework notebook to evaluate during tests. This way, I will not carry your homework with me, and you will have your work back so that you can work on the next assignment in the same notebook. I will not accept the notebook any later than the day I am scheduled to receive it without a doctor’s note. I will expect all work to be shown for each problem.

Instructor Course Policies
More than three unexcused absences will significantly lower your grade. Of course, if you miss many classes, your grade will already be lower naturally. On quizzes and exams, students must show their work in order to receive full credit. If calculators are used extensively, then the student should express in words the process that they are performing with their calculators. In the case of excused absence, the student is responsible for calling or emailing the professor ahead of the class they expect to miss and is also responsible for obtaining a note from a professional documenting the reason for absence and the dates. See the current Student Handbook for the college Attendance Policy especially as it pertains to excused absences.
Any instance of cheating will result in a zero for the assignments, may result in a "F" grade for the course, and could result in referral for judicial review. See the current Student Handbook for the college's Academic Integrity policies as they pertain to examinations, plagiarism, classroom behavior, and the process for handling academic misconduct charges. Cell Phone use in the classroom, including texting, is prohibited. Each instance of texting detected by the instructor during the course of class time will result in an immediate pop quiz for the entire class over the day's material. Such quizzes may recur as often as ten times in one class period.
Structure
In general, one or two class meetings will present material, and the next class session will have a quiz over that material, followed by a lab on the same material. The next meeting after the lab will be the appropriate time to turn in the lab reports from the preceding section.
Lab Reports
I believe that probably the most important thing that a student can get from a physics class is learned in the labs. This learning includes multiple parts:
• Performance of the lab experiment
• Analyzing the data from the experiment
• Utilizing data analysis tools, such as graphs and tables to organize and present data
• Synthesis of data and experiment into a laboratory report.
The lab manual which I have prepared for the course includes not only the instructions for the labs we will perform in class but also includes a section that describes what I expect in a lab report. During the course of the semester, we will perform 12 distinct labs. All students are expected to perform all 12 labs. In addition, each individual student will be expected to write lab reports, as outlined in the laboratory manual, for 5 of those labs. The performance of the labs, as well as the reports will account for 35 % of the course grade.
Institutional and Program-Level Policies
All exams will follow the Final Exam Schedule. Students scheduled to take three or more final examinations on one day may request to arrange their examination schedule, so no more than two exams occur on one day.
Requests for early or late exams are considered only under extreme circumstances. Prior to the exam period, the student must file a written request on the Early/Late Exam Form available in the Student One Stop Center, Academic Records, and on the WC portal. The form must be signed by the Instructor and the Academic Dean, approving the alternate exam time. This process must be completed prior to the scheduled exam period.
Out-of-class Work Expectation A minimum of 2 hours of out-of-class student work is expected for each hour of in-class time for traditional face-to-face courses. For online and hybrid courses, the combination of face-to-face time and out-of-class work should be equal to 3 hours per credit hour per week. |

Academic Misconduct - Examples [10/24]
ACADEMIC CODE OF CONDUCT
This policy is directly related to the first Testimony, which is part of the Student Code of Conduct. “I will practice personal and academic integrity.” The initial responsibility for dealing with academic misconduct lies with the individual faculty member in whose classroom or course of study the offense occurs. The responsibility includes determination of the consequences for the offense. The goal is for faculty to confront cheating and plagiarism, to teach ethical behavior, and to provide an appropriate consequence based on the nature of the incident. Faculty are encouraged to explicitly address academic misconduct and its consequences in the course syllabus.
EXAMPLES OF ACADEMIC MISCONDUCT
A. Examination offenses include, but are not limited to, the following:
1.Taking unauthorized materials into or out of the examination room.
2.Leaving the examination room without authorization before completing an examination.
3.Talking in the examination room without authorization.
4.Discussing the examination outside the examination room during the course of the examination.
5.Attempting to observe the work of another student.
6.Taking an examination for another person or permitting someone else to do so.
7.Collaborating improperly by discussion, joint research, or joint effort in any way expressly prohibited by the instructor. This includes using a cell phone or other device to access information from another source or another student.
8.Improper knowledge of contents of an examination - No student shall knowingly acquire unauthorized knowledge of an examination or any part of an examination, or solicit, offer, or give information about any part of an examination.
B. Student work offenses include, but are not limited to, the following, which are expressly prohibited in the absence of prior written approval of the instructor or instructors involved:
1.Resubmission of work - Submitting work which has been previously submitted for credit.
2. Plagiarism - Submitting work done wholly or partly by another, including the unattributed copying of all or parts of a published work or internet document. Using generative Artificial Intelligence (AI) sources to produce work (when not expressly permitted) is also a form of plagiarism. Some instances of plagiarism are the result of ignorance rather than dishonesty. When plagiarism is encountered, the instructor should be sure that the student knows proper procedures for attributing content.
3.Prohibited sources - Consulting material or persons contrary to the directions of the instructor.
4.Improper collaboration - Engaging in any discussion, joint research, or joint effort of any kind expressly prohibited by the instructor.
5.Deception - Misrepresenting the authenticity of sources, citations, or principles in any written work.
6. Sharing work – Students who share their work with others are responsible for how that work is used. For example, if a student shares a paper with another student to help him or her understand an assignment, and that student submits the work as their own, the author of the paper shares responsibility for the plagiarism committed by the other student.
D. Other misconduct - Engaging in any other improper conduct as specified by the instructor.
E. Lying – deliberately providing false information relevant to academic matters, such as misrepresenting the inability to take an examination because of illness.
F. Disruptive or disrespectful classroom behavior – causing a disturbance in the classroom, interrupting instruction, speaking rudely or threatening students or faculty.
