Course Expectations

D2L Module Quizzes (6)-35%

Students should complete the reading assignments, answer the chapter objectives, and review the questions at the end of the chapter before attempting the module quizzes.

When a student has reviewed a module and is ready for the quiz, he/she will log into D2L and receive a customized timed module quiz consisting of randomized multiple choice questions. Quizzes contain 30 random questions and students will have 60 minutes to complete.

Each quiz may be attempted up to three times. The final score for any module quiz will be the average of all attempts made. It is important to know the module content before attempting the module quizzes since the quizzes are timed. Quiz scores will be available immediately after a student submits for grading.

Each quiz has requirements which must be completed before the quiz will open.

Before the Module 1 quiz can be taken the student must complete all of the following:

  • New Student Survey must be completed
  • Post in the Introduction discussion board

For subsequent quizzes and the final examination, the student must on the previous module quiz:

  • ·Score a 75% or greater on any one attempt; or
  • Successfully compete three attempts of the module quiz (the final quiz score will be an average of all attempts)

For example, in order to take the Module 2 quiz, the student must either score 75% on any attempt of the Module 1 quiz, or complete three attempts of the Module 1 quiz. In order to take the final examination, a student must score 75% on any attempt or complete three attempts of the Module 6 quiz.

All quizzes must be completed by the April 17th or a penalty of 10% off the average score per day late will be assessed. Students who know they will miss a due date because of extenuating circumstances should contact the professor as soon as the circumstance is known. Each circumstance will be considered on an individual basis. Acceptance of an extenuating circumstance is at the discretion of the professor. Since all of the module quizzes are open for three months only the most extraordinary of circumstances will be considered.

If students have technical difficulties during a quiz, they should use the ‘Help’ link located on the top toolbar within D2L to contact the MSU Information Systems Support Staff and send an email to the course professor explaining what happened.

If a student finds a faulty quiz item or believes a quiz question has been scored incorrectly, he/she should send an email to the course professor that includes the following:

  • Module Quiz Number (1-6)
  • Question Stem
  • Rationale Supporting Why the Student’s Answer is Correct
  • Include Page Numbers When Referencing the Textbook

For example, a student cannot send the message: “I think question number ten is wrong on quiz four” because each student gets a quiz of randomly generated test items. The professor has to know the question stem to find the question in the database. After reviewing the situation, if the course professor thinks a revision is justified, the student’s quiz score will be revised to reflect the additional points, and the test bank will be updated.

CT Course Project-30%

The course project is designed to give the student experience working with CT protocols. Before beginning this project, the student survey must be submitted and acknowledged by the instructor in the gradebook. No project will be graded without approval by the instructor. The survey will be used to determine if a student will perform the clinical CT Clinical Experience Project or the Alternate CT Presentation Project.

In order to perform the CT Clinical Experiences, a student must have permission to perform exams on actual patients from their facility. In addition, some states regulations will not allow distance students to perform assignments at facilities within their state’s borders. When you submit your approval form the professor will review your state’s guidelines on a case-by-case basis.

There are instructions within the course for both the CT Clinical Experience Project and the Alternate CT Presentation Project.

No student will begin a project without obtaining the professor’s approval. Every student must submit one form of the CT Course Project to the appropriate drop box by the scheduled due date.

Comprehensive Final Exam-35%

All quizzes and projects must be completed before the Final Exam is taken.

The final examination must be completed by May 4th, 2018 17:00. The final examination does not have a grace period with a penalty like the module quizzes. Students who know they will miss a due date because of extenuating circumstances should contact the professor so their situations can be dealt with on an individual basis. Acceptance of an extenuating circumstance is at the discretion of the professor. Since the final examination is open for one month, only the most extraordinary of circumstances will be considered.

All students are required to have a webcam and microphone for the Final Exam. The appointment with ProctorU must be scheduled by April 1st, 2018.

Exam Format

  • The proctored comprehensive final examination is closed book, and consists of 150 random multiple-choice questions.
  • The exam is a timed, 2 hour (120 min) test.
  • The final exam will be administered using Desire2Learn (D2L) and ProctorU online proctoring service.
  • To prepare for this exam: The final has been derived from the entire content of this course. Review all of your quizzes and your textbook chapters. Reinforcing study materials include the PowerPoint presentations.

What to Bring

  • The student may bring scratch paper with only ProctorU’s phone number on it.
  • No smart watches or any other electronic devices will be allowed.
  • Students are not allowed to print the final exam.
  • No textbooks or notes may be used.

ProctorU Scheduling

  • You may schedule your exam for any time within the testing dates in the course schedule. You must have ALL of your course work complete when you take your final or the final will not be accessible in D2L.
  • For ProctorU instructions, please read the ProctorU Student Instruction Guide in the course and visit the MSU ProctorU Webpage.
  • Be aware certain equipment is required. Review the ProctorU instructions as soon as possible.
  • Contact a ProctorU representative to check your equipment and bandwidth real time before your test date. If anything changes after this check (new computer, updates, ISP changes, etc.), REPEAT the check.
  • All appointments should be made at least three days in advance. To make an appointment, simply create an account by visiting the MSU ProctorU Webpage. Once logged in, click on the new exam link and select the exam, date, and time you desire. You must submit payment (based on the length of the exam) at that time - usually about $25.00. You will receive an email confirming your reservation at the email address you provided to ProctorU.
  •  Late registrations and Take it Now features are subject to availability. Note: If a proctor is not available because you did not schedule your exam in advance, the final is considered missed and a grade of zero will be given.
  • Be mindful when you schedule your final exam. If you schedule the exam outside of the 5-day work week (M-F), there may be no one at MSU available to help if you have technical problems.

Technical Problems

  •  If you are disconnected during your exam, you must immediately send an email to your professor, and immediately contact ProctorU by phone. All exams are monitored and a log is created by the proctor and by D2L.
  • *All times will be documented*
  • The exam must be taken within the scheduled test dates, regardless of any technical issues that may arise. This is the student’s responsibility.
  • Late submissions will not be accepted.
  • My suggestion is to take the exam during the first days it is available (listed below) to avoid receiving a zero due to technical issues. If you have to reschedule, it must be within the scheduled dates and times.
  • See the Technical Difficultiessection above for help options.

All course requirements must be completed before a grade is awarded. Students must complete the final and all course work by the dates published in the course schedule (below).

Note: All assignments received are considered complete and will be graded as such. Any decision of the professor is final and there will be no further changes made.

Submission Format Policy

Note: You may not submit a paper for a grade in this class that already has been (or will be) submitted for a grade in another course, unless you obtain the explicit written permission of me and the other instructor involved in advance.

Late Paper Policy

Due Dates

Most assignments are due on Tuesdays except for the last week of class . Assignments must be submitted by 23:59 (11:59 pm) Central time, on scheduled due dates in the course schedule. If a student fails to meet a deadline the student will receive no credit for the assignment not submitted on time.

Emergency Extension

If you have a major event such as a death in the family, illness, hospitalization, or other extenuating circumstances, email the professor as soon as possible and on or before the scheduled due date. I will grant extensions on an individual basis. If an extension is granted, typically the following guidelines will be followed.

  1. The assignment may be up to one week late and still qualify for full credit. After the one-week extension has passed, ten points per day can be deducted until the assignment is no longer worth any credit.
  2. When the assignment is completed, you must send a follow-up email to let the professor know it is ready to grade. Failure to notify the professor could lead to a grade of zero.
  3. Avoid End of Course Late Work: Please note there are University deadlines for submitting grades at the end of the emester. All work must be turned in at least a week before grades must be posted.
  4. If a course includes interaction between students in the discussion board, and if extenuating circumstances will prevent you from participating, an alternate assignment may be considered at the discretion of the professor.

Plagiarism Policy

Plagiarism is the use of someone else's thoughts, words, ideas, or lines of argument in your own work without appropriate documentation (a parenthetical citation at the end and a listing in "Works Cited")-whether you use that material in a quote, paraphrase, or summary. It is a theft of intellectual property and will not be tolerated, whether intentional or not.

Student Honor Creed

As an MSU Student, I pledge not to lie, cheat, steal, or help anyone else do so."

As students at MSU, we recognize that any great society must be composed of empowered, responsible citizens. We also recognize universities play an important role in helping mold these responsible citizens. We believe students themselves play an important part in developing responsible citizenship by maintaining a community where integrity and honorable character are the norm, not the exception.

Thus, We, the Students of Midwestern State University, resolve to uphold the honor of the University by affirming our commitment to complete academic honesty. We resolve not only to be honest but also to hold our peers accountable for complete honesty in all university matters.

We consider it dishonest to ask for, give, or receive help in examinations or quizzes, to use any unauthorized material in examinations, or to present, as one's own, work or ideas which are not entirely one's own. We recognize that any instructor has the right to expect that all student work is honest, original work. We accept and acknowledge that responsibility for lying, cheating, stealing, plagiarism, and other forms of academic dishonesty fundamentally rests within each individual student.

We expect of ourselves academic integrity, personal professionalism, and ethical character. We appreciate steps taken by University officials to protect the honor of the University against any who would disgrace the MSU student body by violating the spirit of this creed.

Written and adopted by the 2002-2003 MSU Student Senate.
