摘要：The present study was an attempt to explore the effect of teaching writing through critical thinking and multiple intelligences on the Iranian students’ writing ability. In doing so, 120 students of RAD university took part in the study. The pre- and post-test of writing was used in order to collect the data. Critical thinking strategies aimed to develop the students’ cognition to raise their own questions regarding the writing tasks and be able to create their own statements through logical reasoning and evaluating their statements by sharing their responses with their peers. Multiple intelligences inspired from Gardner’s (1983) theory was also applied as a technique to help students’ writing. The focused intelligence types included linguistic, logical-mathematical, spatial, bodily-kinesthetic, musical, interpersonal, intrapersonal, and naturalistic. Quantitative analysis revealed that critical thinking strategies had significant impact on the students’ writing ability. However, only linguistic and interpersonal types of intelligence resulted in the students’ significant improvement in writing. Findings contributed to use of critical thinking and multiple intelligence to develop students’ potential in writing.
