Studying abroad (SA) represents a valuable experience for many students within higher education settings. Recently, the number of students choosing to SA within higher education has risen. Quantitative and qualitative research indicates that SA improves learning as related to ancillary types of learning outcomes, such as with cultural awareness (CA). CA is knowledge gained about similarities and differences among and between cultural groups. The goal of the present quantitative review was to compile and evaluate, in a comprehensive manner, published findings, addressing the impact of SA in higher education on CA. To accomplish this goal, articles reporting empirical results were collected, and effect sizes for statistical comparisons were calculated. Across 28 independent studies, SA was found to be associated with marked increases in CA (mean effect size, d = 0.569). A critical evaluation of empirical studies on SA and CA shows many important flaws and limitations. Many studies are based on self-report data derived from relatively small samples of US students studying abroad for 1 year or less. This quantitative review provides support for the hypothesis that SA may improve CA, but also demonstrates the need for further rigorous research to be conducted in this area.
