A class of secondary students in Greece implemented cooperative learning techniques to teach a lesson on conditionals in English. The class was divided into six groups, with each group assigned a different part of the conditional theory to learn and present. Groups took turns presenting their section at the board. Students then completed feedback exercises in their groups which were corrected by the neighboring group in a chain. The solutions were presented and discussed by the whole class, allowing students to cooperatively learn the material through group work and peer teaching.
