Abstract
The purpose of this study was to assess the knowledge acquired from completing online case-based e-learning modules. A secondary objective was to identify how students use these independent resources and gauge their level of support for this novel instructional strategy.
Fourth year medical students were randomized to either a module or control group. Both groups received the standard musculoskeletal medical school curriculum, while the students in the module group were also given access to case-based online modules created to illustrate and teach important orthopaedic concepts related to unique clinical presentations. The first module depicted an athlete with an acute knee dislocation while the second module portrayed a patient with hip pain secondary to femoral acetabular impingement (FAI). All participating students completed a knowledge quiz designed to evaluate the material presented in the module topics, as well as general musculoskeletal concepts taught in the standard curriculum. Following the quiz, the students were invited to share their thoughts on the learning process in a focus- group setting, as well as an individual survey. Demographic data was also collected to gauge student's exposure to and interest in orthopaedics, emergency medicine, anatomy and any prior relevant experience outside of medicine.
Twenty-five fourth year medical students participated in the study with 12 randomized to the module group and 13 to the control group. The regression revealed students in the module group did on average 18.5 and 31.4 percentage points better on the knee and hip quizzes respectively, compared to the control group, which were both significant with a p-value < 0.01. Additionally, students who had completed an orthopaedics elective did 20 percentage points better than those who had not, while there was no significant improvement in students who had just completed their core orthopaedics rotation. The feedback collected from the survey and small group discussion was positive with students wishing more modules were available prior to musculoskeletal clinical skills sessions and their orthopaedics rotations.
Medical students given access to online case-based e-learning modules enjoyed the innovative teaching strategy and performed significantly better on knowledge quizzes than their classmates who only received the standard musculoskeletal curriculum.
