Information and Communication Technology has the potential to make education more effective and more efficient. Various projects and persons have created sophisticated tools, like ActiveMath, MathDox, OMdoc, STACK. These systems incorporate very advanced tools that can revolutionize education. Yet they are not being widely used. In fact, all the efforts to develop systems, services and content have resulted to mere scratches on the surface of traditional education if measured by revenues of eLearning and those of traditional instruction.

In spite of this we should not give up. We must find sweet spots where ICT tools can really improve instruction. Assessment is one such sweet spot. This talk describes how real time quizzes can be used in instruction. Real time quizzes, based in the use of special personal response systems – devices slightly large than a cellular telephone – change the dynamics of a class in a fundamental way. Students are more focused, when they know that they will soon have to answer quiz questions. This results in improved learning. And, most importantly, overwhelming majority of students found the real time quizzes useful.
