Taking full advantage of the Web technology platform dur- ing in-class lectures requires a shift from the established scheme of online education delivery that utilizes the video channel to embed all types of content and gathers student feedback via multiple choice questions or textual answers. In this paper we present the design of ASQ to deliver interactive content for use in heterogeneous educational settings with a large number of students, taking advantage of the co-location of students and instructors and building upon the latest capabilities of the Web platform. ASQ is centered around interactive HTML5 presentations coupled with a versatile microformat to create and deliver various types quizzes and scalable, synchronous/asynchronous feedback mechanisms.
