Interactive versus Collaborative Writing Instruction: An Experimental Study

This study investigated the effects of Interactive and Collaborative Instructional pedagogies on Iranian EFL learner's writing. It adopted pre-test and post-test control group quasi-experimental design with two experimental and one control groups. The participants were 90 college students in two branches of Islamic Azad University. The main data collection tool was an essay writing task. Data were analyzed using ANCOVA. Pre-test post-test comparisons revealed that students who received interactive pedagogy gained the most from the instruction t= -18.302; p = 0.000; p 0.5. The total variance accounted for by all the independent variables taken together was 51% (i.e. W2 = 0.51%). Findings indicated that interactive pedagogies befitted students more than collaborative ones.
