This study brings together the fields of cooperative learning, second language
acquisition, as well as second/foreign language teaching to create optimal schooling
experiences for junior high school students. Integrating cooperative learning with
the theories from the second language acquisition, i.e. the comprehensible input, the
comprehensible output, the interaction and context, and the affective domain of
motivation, the researcher hopes that this empirical study can provide a close link
between cooperative learning and the communicative language teaching and, at the
same time, propose guidelines for EFL teachers who wish to implement cooperative
learning to enhance their students’ proficiency in English as well as motivation
toward learning English.
