摘要：Background and aim: Audience response (AR) systems are increasingly used in undergraduate medical education.However, high costs and complexity of conventional AR systems often limit their use.Here we present a novel AR system that is platform independent and does not require hardware clickers or additional software to be installed. Methods and results: “OnlineTED” was developed at Technische Universität München (TUM) based on Hypertext Preprocessor (PHP) with a My Structured Query Language (MySQL)-database as server- and Javascript as client-side programming languages.“OnlineTED” enables lecturers to create and manage question sets online and start polls in-class via a web-browser.Students can participate in the polls with any internet-enabled device (smartphones, tablet-PCs or laptops).A paper-based survey was conducted with undergraduate medical students and lecturers at TUM to compare "OnlineTED" with conventional AR systems using clickers."OnlineTED" received above-average evaluation results by both students and lecturers at TUM and was seen on par or superior to conventional AR systems.The survey results indicated that up to 80% of students at TUM own an internet-enabled device (smartphone or tablet-PC) for participation in web-based AR technologies. Summary and Conclusion: “OnlineTED” is a novel web-based and platform-independent AR system for higher education that was well received by students and lecturers.As a non-commercial alternative to conventional AR systems it may foster interactive teaching in undergraduate education, in particular with large audiences.
