The Elmo CRV-24 Student Response System allows teachers to record student responses into ImageMate Accent for SRS software and teachers can then review student's performance and understanding of the material.
In just a few easy steps, classrooms can be transformed into a hub for interactive learning. Before starting, insert the wireless USB adapter into any computer for plug-and-play use -- you won't need to install any drivers. Then, the teacher asks a question with an Elmo document camera and any teaching materials like textbooks or handwritten documents can become an Elmo SRS quiz bank. The SRS also works with nearly all types of computer program files and content like Word, Excel, PowerPoint, Web content and more. Students then respond by using the clicker to key in their answers, which are recorded in the software database.
Results are instantly tabulated and displayed in bar graphs or pie charts, so the teacher can assess the performance of each student in comparison to the whole class. This effectively measures student comprehension in real time and enhances student participation and motivation to learn.
