Review of Two Classroom Response Systems for Instant Student Feedback
Educators: are you looking for instant feedback from your students? Consider one of the following student response systems for your classroom. A brief description of system features is listed below:
|The i>clicker interactive student response system relies upon a base unit with proprietary software and dedicated presented remote (hundreds of dollars) plus a remote-controlled “clicker” unit used by each student ($40+ per student, plus shipping, plus batteries). After the teacher uses a computer to enter questions and possible multiple-choice answers, and after students register their remote-control units online, students indicate their responses by pressing the corresponding button on their remote-controlled unit. Responses are communicated to the instructor over radio frequencies; to avoid interference, students and teachers in each classroom should align clicker unit frequencies by pressing the power button until their unit indicator lights flash, after which point each student should enter the same two-digit frequency code to enable communication from their unit. Students are advised to monitor battery status; units that lose power will not register responses with the central system.
||An alternative to clicker technology in your classroom involves time-tested technology with “retro” appeal. This mode of instant student response technology can be used with supplies that are available everywhere at a low cost (less than 10 cents) and easily replaced in case of malfunction, although single units can be used repeatedly over the course of a semester. After the teacher reads a question aloud or writes it on a chalkboard, student responses can be instantly communicated to the instructor over the standard electromagnetic spectrum with the support of standard classroom lighting or sunlight, in a manner that is impervious to radio-wave or infrared interference problems. In tests, technology crash rate is effectively 0%.
