Assignments:
Reading Assignments
Homework Assignments
Laboratory Assignments
Methods of Evaluation:
1.
This is a degree-applicable course but substantial writing assignments are NOT
appropriate because this course, primarily, involves skills demonstrations or problemsolving tasks.
2.
Computational or non-computational problem solving demonstrations include laboratory
applications and objective examinations.
3.
Skills demonstrations include both performance examination and evaluation and clinical
evaluation and assessment.
4.
Objective examinations include: multiple choice, true/false, matching items, completion
and limited essay type questions.
Grading System:
Grading is on a total point system. Points are then transferred to a percentage. Percentages are
as follows:
A = 92 – 100%
B = 83 – 91%
C = 75 – 82%
D = 66 – 74%
F = 65% and below
Assignments = 10 – 35 points each
Late Assignments = ½ value of possible points
Test/Exams:
Mid-term/Final = 100 points each
Unit Exams = 40 – 60 points each
Quizzes = 15 – 30 points each
Make-up tests will have an automatic 10% deduction in points
Textbooks:
1.
Principles of Radiographic Imaging by Richard R. Carlton, Arlene M. Adler Delmar
Publishers, 2006 4th edition.
2.
Principles of Radiographic Imaging Laboratory Manual/Workbook by William Finney,
Richard Carlton, and Arlene Adler Delmar Publishers, 2006 4th edition.
Tests, Quizzes, Assignments:
Tests will be announced ahead of time. If a test is missed, it must be made up. Make-up times
will be arranged with the instructor at the instructor’s convenience. There will be an automatic
10% deduction in the test score.
Quizzes will be given without warning and cannot be made up.
Assignments will be given with a due date and/or time. If the assignment is turned in one period
late, 10 points will be deducted automatically from the score. Assignments turned in later than
one class period will receive a zero. If the assignments are not turned in at all, the student will
not pass the course. Assignments are considered late if not turned in at the beginning of the
class period.
Attendance:
If you are going to be late or absent for any reason, you must contact the Radiologic Technology
office and leave a message on the voice mail. You are encouraged to contact the instructor
directly at (626) 585 -7149 or (626) 340-9714 in case of absence or tardiness.
Actions relative to absences will follow the school policy.
A student may be dropped by the instructor when the total number of hours of continuous or
cumulative absence, regardless of cause, is equal to the number of hours in the class is scheduled
to meet in a two-week period (see college catalog).
Tardiness and absences will have a five (5) point deduction each on the final grade. Three
occasions of tardiness will be equal to an absence.
