Summary

Currently, teaching X-ray interpretation to medical students is not standardized, and is generally not very effective.

Objective: The goal of our study is to evaluate whether directly teaching an expert search strategy for x-ray interpretation to 3d year medical students is effective.

Methods:

* An expert's visual search strategy was recorded using a gaze-tracking device. The search strategy was then reproduced using a dynamic cursor moving across the corresponding chest x-ray, and incorporated into a teaching program accessible via the internet.
* Participants are 3rd year medical students who will be randomized into two groups. The experimental group will have access to the teaching program as described. The control group will have access to the same x-rays but not the expert's search strategy.
* At the end of the study period the investigators will collect performance data (the participants' accuracy at reading a series of chest x-rays) and process data (using gaze-tracking to evaluate the participants' search strategies); the experimental and control groups will be compared.

Expected results:

The investigators expect the group trained in expert search strategy to show improved accuracy at reading chest x-rays, and an improvement in their visual search strategy
