An important component of the safe operation of agricultural equipment is the ability to read and understand universal symbols. The Internet educational module is designed to help participants recognize these symbols. The impact of using it was evaluated using a field trial study. Assessment consisted of pre- and post-tests. Youth who had access to it averaged an improvement 29 points higher on the post-test than that of the control group. Overall, the Internet learning environment increased participants' ability to recognize universal symbols faster and more accurately. The study serves as a model for supplementing Extension programming with Web-based educational material.
