Prior to or at the conference, the student shall submit the written statements required at Level Two and the date of the conference with the Vice President of Student Affairs.
After exhausting Amarillo College’s grievance/complaint process, current, former, and prospective students may initiate a complaint with The Texas Higher Education Coordinating Board. Directions are available at the following location: https://www.highered.texas.gov/links/student-complaints/
COURSE ETHICS
Grading Distribution:
The course grade will be computed as follows:
Average of Unit/Chapter Examinations = 40%
Average of quizzes/graded-assignments/Radiation Safety Assignment = 20%
Final Comprehensive Examination = 40 %
The following grade scale shall apply during this course:
A= 91.5-100
B= 82.5-91.4
C= 74.5-82.4
F= less than 74.5
A grade of “D” is not possible in this course!
You alone are responsible for your final semester grade. The instructor will not round final grades up to increase your letter grade.
There is no extra credit available for this course. All grades are important, I encourage each student to put forth extra effort from the start of any course.
Non-scheduled assignments/pop quizzes cannot be made up, if missed, a grade of zero will be entered into the grade book. Any/All scheduled assignments/quizzes/exams that are scheduled and not completed in the time or place scheduled can be completed but with only 80% of the original score within the first 24 hours, after 24 hours, a zero will be added into the gradebook. For example, if a quiz is scheduled during an in-class meeting and you are not in class, you can complete, but the 20% reduction will be applied. You are responsible for turning in your assignment complete and on time by the due date and time.
Unit exams can be made up if a student misses the exam on the scheduled day/time. Timely arrangements will need to be set up by the student to complete the make-up exam within 1-2 school days. Make-up exams will receive only partial credit of 80%.
*Partial credit refers to 80% of the original maximum point value.
For example, if a student takes a 100-point unit examination at an unscheduled time or late due to an absence. If the score is 90% on the make-up exam, a 72% (90 x.80=72) will be recorded in the grade book.
In the case of extreme circumstances, the instructor will consider elimination of the 20% reduction if prior arrangements have been made with the instructor.
Any scored activity not completed in accordance with these policies shall be scored as ZERO credit and will be averaged as such into the final course grade.
Radiation Safety Assignment
RADR 2313 will consist of a Radiation Safety Assignment that will count as a two quiz grades in the grade book.
Radiography Program Tutoring Policy
Mandatory tutoring (may be in the form of class remediation, post exam worksheets, a personal meeting with the instructor, or other as deemed necessary) is required if a student scores below 75 on a major exam in the course. It is the responsibility of the student to complete/attend a tutoring session or activity before the next exam. Students who fail to attend tutoring will not be allowed to take the next test until remediation is done.
Remote Testing Rules
1. During the pre-exam portion, students are required to take a student photo, show valid photo ID, and preform a complete environment scan with the detachable web cam. Any approved blank scratch page or standard calculator (nonscientific) must be shown on pre-exam scan. After the complete environment scan, you should properly place the detachable web cam. A properly placed web cam should be at about a 45° angle You will also need sufficient lighting during the pre-exam and exam portions and the microphone must be turned on and recording.
A. Approved scratch paper: (1) 8.5 x 11 dry erase sheet that is supplied by the instructor (if you are supplied with the dry erase sheet, that is the method you should utilize) or (2) blank piece of paper (can only be utilized if a dry erase sheet is not supplied by the instructor) that is no larger than 8.5 x 11, if utilizing this type of scratch paper, it must be torn up or cut up in view of the instructor after completing the exam and prior to the video being terminated.
B. Approved calculator: standard nonscientific calculator or the enabled standard calculator in Respondus Lockdown browser.
2. No smart technology allowed in the same room, other than the computer on which you are testing. (no tablets, smart watches, etc). If a calculator is required, you can utilize a basic calculator and have a blank piece of scratch paper that is no larger than 8.5 x 11.
3. You may not leave the room for any reason during the exam, plan accordingly for this.
4. If you are booted off the exam, you may retrieve your phone because you must take a screen shot of what it shows when it boots you off and send it to the instructor immediately.
5. If you are booted off, you must immediately attempt to log back in to the exam.
6. No two students (or more) may test in the same room at the same time. Each student should be alone while testing.
Failure to comply with any of the above rules will result in a 10 point reduction in the test grade for EACH infraction. For example, if you get booted off and wait 30 minutes to log back in (which the instructor can monitor) and you do not take a screen shot and send it to the instructor, that will result in a 20 point reduction of your test grade. If you are sick and think you may need to leave to go to the restroom, do NOT begin the exam. Contact the instructor to work out a different time to take the exam.
Any student who thinks that a penalty was misapplied can request that the penalty be reviewed according to the grievance procedure.
Regular and punctual attendance is necessary for satisfactory achievement. It is the responsibility of the student to attend class. The student is responsible for any missed information from any missed classes.
If a student is in attendance for an exam, but does not have his or her laptop and is unable to take the exam during the scheduled day/time, it will be considered a missed exam and the partial credit from section above will then apply when the student schedules the make-up exam.
