This paper is a report on an experimental study which intended to look into the
possible effects of Competitive Team-Based Learning (CTBL) vis-à-vis Group
Investigation (GI) method of Cooperative Learning (CL) on the language
proficiency of Iranian EFL intermediate students. Seventy homogeneous Iranian
intermediate students were selected out of a total population of 110 to serve the
present study. The results of the study indicated the advantage of CTBL over GI in
terms of its effect on improving the target group’s language proficiency. The
results of the study were in contrast to the reports of researchers like Ab-Raza
(2007), an Israeli language specialist, who have argued that students in Islamic
countries “do not value diversity of ideas, beliefs, and perspectives” (p. 5) and so
cannot be taught through modern methods like those of CL.
