Peer Teaching takes the idea of students-teaching-students and applies it to a structured learning environment. While teachers still make and implement most of the content, students take on the responsibility to instruct during and after the learning trials. Students, called tutors when in the instructional role, are trained to observe and analyze other students’ practice attempts. Students spend equal time as tutors and as learners. This increases effectiveness of the teaching time and allows the teacher to cover more content in a unit.
