This document summarizes a research paper that examined the effect of authentic versus inauthentic materials in cultural awareness training on English language learners' listening comprehension abilities. 116 English learners took a placement test, and 60 intermediate students were selected for the study. They were randomly assigned to a control or experimental group. The control group used inauthentic materials for listening activities, while the experimental group used authentic materials. Both groups took a pre-test and post-test to measure changes in their listening abilities. Statistical analysis found that the experimental group showed significantly greater improvement compared to the control group, suggesting that authentic materials may be more effective than inauthentic materials for developing listening comprehension.
