Effects of using Instagram on learning grammatical accuracy of word classes among Iranian undergraduate TEFL students

Abstract

This study was an attempt to investigate the effects of Instagram application on learning grammatical accuracy of word classes of Iranian undergraduate TEFL students as well as to find out Iranian undergraduate TEFL students' perceptions of using Instagram application for learning grammatical accuracy of word classes. In doing so, an Oxford Placement Test was administered among 120 TEFL students, and based on the results, 92 students, studying in Islamic Azad University of Najafabad, Isfahan, Iran, were randomly selected. Then they were divided into two equal experimental and control groups (N=46).Their age ranged between 19 and 26 years old. Gender of participants was not considered as a variable in the study. The experimental group was taught grammatical accuracy of word classes via Instagram application, whereas the control group only followed conventional treatment. Analyzing the data through the independent sample t-test revealed that with the help of Instagram application, the experimental group outperformed the control group in terms of learning grammatical accuracy of word classes. Furthermore, Iranian TEFL undergraduate students had a positive attitude toward utilization of Instagram application.
