The Biomechanics Unit is a part of PT245 Principles of Human Anatomy. Dr. Mattingly is the principle instructor and administratively responsible for this course. All department and course policies and procedures as listed in the overall course syllabus will be followed. If in doubt, please ask Dr. Mattingly or me.
Class Meeting
Days, Times and Location:
Lecture - Tuesday and Thursday
Unit Description: This unit covers introductory topics that are required to understand Kinesiology PT375 (see list of topics below under Unit Schedule and Objectives). There is a lot of material to understand. Students must engage in independent, active learning (using the web page, course notes, and textbook). Those who depend on “passive” teaching will not succeed.
Required Textbook
and Resources:
· Course Notes: Available as a download from my web site. Bring these to class each day.
·
Textbook: Neumann DA, Kinesiology of the
Musculoskeletal System: Foundations for Physical Rehabilitation, Mosby,
· Textbook Web Site: http://evolve.elsevier.com/staticPages/index.html
· Unit Web Page: http://academic.uofs.edu/faculty/KOSMAHLE1/default.htm - use PT245 link
Please use this web page frequently! Review the materials and graphics on this web page regarding lecture topics before attending lecture.
Teaching Methods:
Lecture, question and answer, discussion.
Professional Behavior:
Physical therapy
majors are expected to exhibit professional behavior at all times (see relevant
sections of the PT Department Student
Handbook and section 3.8.3.3 “Professional Behavior” of the Evaluative Criteria for Accreditation of
Education Programs for the Preparation of Physical Therapists, CAPTE,
Effective
·
conform to the
· attend all class meetings and activities.
· be punctual, prepared (including lab clothes and equipment when appropriate) and participative.
· accept responsibility for their actions (eg. accept that grades reflect each student’s effort and output).
How the Student is Evaluated:
· Attendance:
Attendance and participation in all course activities are the required norm. Chronic absence, lateness, and/or lack of participation will result in a final grade reduction of as much as 10% at the discretion of the instructor. Please also see PT Department Student Handbook policy on attendance.
· Two quizzes – 10 points each – total quiz score equals 33.33% of unit grade
· One exam – about 45 questions – score equals 66.67% of unit grade

Note: Course grades below 77.00% are unacceptable for progression through the curriculum and will initiate the probation policy - See PT Department Student Handbook. Grades on tests, quizzes, assignments, etc., are recorded in percentage form carried to two decimal places (e.g., 76.84%). Whole numbers are not affected at all by rounding the decimals. Please don’t ask for adjustments to grades. . |

Policy on Reviewing Tests and Quizzes:
We will review the quizzes in class as soon as I have them graded. For the exam, answer sheets will be returned as soon as I have completed grading all tests. Students may review test answer keys that will be posted at that time. Any additional review of tests and/or test questions is completely at the discretion of the instructor.
