    Grading Policies

    Attendance: A grade is awarded for attendance in this class. Roll will be taken through a sign in sheet; if you fail to sign in you are considered absent. You will be given a 1 for attendance each day. If you are tardy, (15 min. late), or leave early the grade will drop to a ˝ and if you do not show up, you will receive a grade of 0 for that day.  (IF YOU ARE LATE FOR A Legitimate REASON, YOU NEED TO SHOW THE INSTRUCTOR A DOCUMENTED EXCUSE!) School sponsored activities, illness, and emergencies will not count against attendance if proper notification from Professor/Coach/Doctor/Parent/Etc. is given. All unexcused absences will cost you points. Students who have zero (unexcused) absences will be allowed to drop their lowest exam score and replace it with their highest exam score!

    Homework: Assignments will consist of problems assigned from the textbook, ranking task book, and the Tipers book. The problems will be graded for correctness and completeness.

    Journals: Journals will be required for text sections as assigned. The format of a journal entry is as follows:

    A) Main purpose(s) of this section.
    B) The most important information and concepts are . . .
    C) Muddiest point: what do you find most confusing about this section?
    D) Examples: give two solved example problems of this section. They do not have to be complicated problems.

    Biographical journals will have a format as follows:

    A) Biography of the scientist (should deal with physics!)
    B) The most important theory(ies) of the scientist is/are . . .
    C) How do you think this scientist has impacted our world?

    Quizzes: Quizzes may be given at any time. Always be prepared for a pop quiz. Take-home quizzes will also be given. Quizzes will be part of the homework grade.

    Exams: All exams (except the Final) will be given in the testing center in the Student Center. Tests will be given over a 5 day period (including weekends). The dates will be announced in class. Make-up exams will be given only for excused absences with notice.  All tests will be announced at least two class sessions before they are given.
    * On test days the students will be allowed to use notes on the exam!

    * Provide testing center staff with: 1) Government issued picture ID. 2) Course Name and Number. 3) Professor's Name. 4) Exam Number.

    Lab Policies: Laboratory attendance is required. You should bring a straight edge and a scientific calculator to lab. A lab report is due at the beginning of the following week's lab. The following shows the required format of a report:

    Title: Example: Electric Field Mapping.

    Introduction: State briefly what the goal of the experiment is. Use future tense. Examples: The purpose of this experiment is to demonstrate the vector nature of electric fields.  We will measure the length of a table.

    Procedure: Explain the steps you took in order to perform the experiment. In this part of the lab, use diagrams to show equipment used. Use past tense here and for the remainder of the lab. Example: A setup consisting of two voltmeters, conducting paper, two electrodes, wires, and probe, was used to map voltage lines and electric fields.  Figure 1 shows the apparatus. Etc......

    Data: In this part of the lab, show the data you obtained from the experiment. This is the place for tabulated data. Place data tables here.

    Analysis: State your result. State how you obtained your result. The result is obtained either by the use of a formula or by graphing. Show all graphs and calculations here.

    Error Analysis: Calculate the error of your result. This is performed either by use of a formula or graph. The graphical method would appear on a graph(s) of the preceding section.

    Conclusion: State briefly what was done in the lab and the result obtained. Example: A curved track and video camera was used to measure the acceleration due to gravity. We found the value of g to be 9.78 +/- 0.30 m/s^2. The accepted value is 9.80 m/s^2, giving experimental agreement.

    Each lab is worth 10 points. The lab report is worth 5 out of the ten points. Properly filled out data sheets are worth 5 points. The data sheets should be placed at the back of the report. The report should be typed on a computer.

    Pre-lab: Pre-labs are due at the beginning of the lab. You will be told if a pre-lab is required for next week’s lab. The format of a pre-lab is as follows:
    Main Purpose
    Key Concepts

    Lab Project: Assessment of some course objectives will be performed with a lab project. Students will spend some lab time and outside of class time, constructing a lab project. Near the end of the semester, the lab project should be completed. A completed lab project will consist of the following: 1) A built apparatus that demonstrates important physics concepts. 2) A demonstration to the class on how the apparatus works and concepts behind it. 3) A lab report on the project.

    It is recommended that you keep your homework, journals, and quizzes organized in a three-ring binder and have them with you each class session, so that you are prepared to ask questions about the homework, and for use in exam preparation.


    Final Exam: The Final Examination will be a comprehensive exam with a greater emphasis on the untested material. Typically, the PH224 final has 40% of the content as already tested material, and 60% of the content is untested material.
    * You will be allowed to use notes on the Final Exam.

    Academic Honesty
    Each student is expected to maintain the highest standards of honesty and integrity in online academic and professional matters. The College reserves the right to take disciplinary action, up to and including dismissal, against any student who is found guilty of academic dishonesty or otherwise fails to meet these standards. Academic dishonesty includes, but is not limited to, dishonesty in quizzes, tests, or assignments; claiming credit for work not done or done by others; and nondisclosure or misrepresentation in filling out applications or other College records. Cheating or gaining illegal information for any type of graded work is considered dishonest and will be dealt with accordingly.

    Americans with Disabilities Act (ADA) Information
    Any student requiring special accommodations should contact the Special Needs Student Services Coordinator at (575) 492-2576 or by e-mail at

    Attendance Policy
    Attendance is required at every session of each course for which the student is enrolled. When unavoidable circumstances make attendance impossible, students must provide a satisfactory explanation of their absences to their professors. College-sponsored activities are considered excused absences and the appropriate sponsor of those students who will be absent from class will notify professors. Students having absences due to college-sponsored activities will need to make arrangements with the affected classes / professor to take care of required work; however, arrangements for make-ups should be made within a reasonable time frame, usually within one week of the absence. Regarding make-up work, absences due to late registration are considered the same as regular absences.

    Cell Phones/Pagers
    All cell phones and pagers must be turned off when the student is participating in any lecture, laboratory, or other learning activity.

    Classroom Conduct
    The professor is responsible for maintaining a class environment best suited for effective learning. By registering for this class, the student is assumed to have entered into an agreement with New Mexico Junior College and the professor to attend the class regularly and to behave in an appropriate manner at all times. Disruptive behavior may result in the student being removed from the class.

    Food and Drink Policy
    Food items and soft drinks may not be consumed in NMJC classrooms. Students are also discouraged from bringing food and drink items into the classroom even though these items remain in sealed packaging. Bottled water is permissible.

    No Children in the Classroom
    In order to adhere to instructional procedures as well as maintain the safety of children, NMJC’s policy of no children in the classrooms (lecture, lab, etc.) will be followed.

    Offering the work of another as one’s own, without proper acknowledgment, is plagiarism; therefore, any student who fails to give credit for quotations or essentially identical expression of material taken from books, encyclopedias, magazines and other reference works, or from the themes, reports, or other writings of a fellow student, is guilty of plagiarism. Plagiarism violates the academic honesty policy and is considered cheating.

    Smoking/Use of Tobacco
    New Mexico Junior College is cognizant of the health hazards associated with smoking / use of tobacco for the smoker, as well as the non-smoker. In an effort to provide a healthy environment for students, employees, and others who may frequent the campus, NMJC prohibits smoking / use of tobacco inside any campus building or facility.

    Tutoring Assistance
    Free tutoring services are available to all NMJC students through Brainfuse and the Academic Success Center located at the Pannell Library on the 1st floor.

    Withdrawal Policy
    Regular, punctual attendance is required for all classes at NMJC. Although the professor has the right to drop any student who has missed the equivalent of 2 weeks of instruction (based on a 16 week semester) whether it’s a face to face, online, or a hybrid course, it is not guaranteed that the professor will drop the student. If the student chooses to stop attending a class, he/she should withdraw from the class by accessing your student account in the T-Bird Web Portal at, or submitting the required paperwork to the Registrar’s Office by 5:00 p.m. on Thursday, April 18, 2019. All students are encouraged to discuss their class status with the professor prior to withdrawing from the class.
