Definitions, Features, and Technologies on Classroom Response Systems: A Systematic Literature Review

Classroom Response System (CRS) is a learning technology that supports face-to-face learning sessions by gathering responses to questions given by teachers in classroom which provides feedback to teacher during learning process using electronic devices. This paper described the definition of CRS and also its features and technologies with Systematic Literature Review (SLR) method. SLR was conducted to trace related studies trough three reputable journal database; IEEE Xplore, ACM Digital Library, and Sciencedirect. From 17,809 articles gathered, only 20 articles are eligible for synthesizing. The results are: CRS can be defined as a system used to support interaction and engagement between teachers and students in the classroom. CRS adopts an electronic voting system where the teacher displays questions via projector screen and students respond to them by answering through input device; the types of questions that can be accommodated by CRS can be grouped into three features, namely simple type interaction, text based interaction, and freeform based interaction; CRS takes the advantages of existing hardware and no longer used proprietary hardware.
