“…The social interactionist theory of language acquisition places more emphasis on learning language through more informal situations such as discussions. Peer-mediated instruction (PMI) has been demonstrated as effective with ELs (Calhoon, Otaiba, Cihak, King, & Avalos, 2007;Choi, Oh, Yoon, & Hong, 2012;Jozwik & Douglas, 2017a;McMaster, Kung, Han, & Cao, 2008;Sáenz, Fuchs, & Fuchs, 2007) which occurs through Peer Assisted Learning Strategies (PALS) or Cooperative Learning Structures (CLS).
