Enhancing student-centered learning in Biomechanics (KINE3050) using new and emerging technological educational tools

Project Abstract

Wikis

This project redesigned KINE-3050 (Biomechanics)

as a blended

course

aim to enhance student-centered learning by: (1) developing online in

with the
teractive

0 Informational website (similar to Wikipedia) incorporate

" Made by students in groups (n=6 per group)

learning modules and laboratory assignments and (2) Increasing and improving the

" Practical aspects of

Biomechanics in a sport

or profess

new technologies to enhance student learning and engagement (Wikis and

Clickers).

" 5 different topic pages:

" 1) Introduction,

Online Learning Modules
Covered topics:

" Work

and Energy

" Angular Kinematics
" Forces
" Tissue Stress
" Bone and Joints

Each module includes, interactive

Angular Kinetics
Angular kinetics describes the angular motion and the forces that cause or tend to cause that motion. Angular kffietic

Torques
Torque is described as being the product of force and the forces moment arm. Torque force is critical for the muscles andjoi
