Then, IELTS pre-intermediate speaking and writing tests were taken as the pre-test to make sure that they have failed to have a previous knowledge of objective structures. Unlike the control group, the participants in the experimental group were told to apply critical thinking instructions in learning speaking and writing skills. After intervention, the same pretest was taken to the participants in both groups as the posttest to determine the result of gaining the medical aid. Independent and paired sample t-tests were run to answer the research questions. The results indicated that critical thinking is highly contributive in learning productive skills.
