This study investigated cultural learning by 194 high school students in summer study abroad programs. Quantitative analysis was used to determine if significant changes occurred in self reports of cultural, linguistic, and interpersonal challenges in the target culture; understanding of target-culture perspectives, practices, and products; and identification with native versus target culture after study abroad. Outcomes in each area were compared between homestay and non-homestay participants.
