This qualitative dissertation explores the classroom experiences of international undergraduate students in the U.S. with a specific focus on perceptions of undergraduate Chinese international students. The study starts with a literature review of the field of study where I identify classroom practices that, instead of promoting integration of international students into classroom activities, facilitated exclusion and segregation of these students. Subsequently, I explore different classroom practices perceived by 15 Chinese international undergraduate students to be effective and those perceived to be ineffective. At the same time, perceived identity of these Chinese international students in a U.S. classroom setting and how these affect their experiences and sense of membership are also explored. The study concludes with a series of recommendations under a proposed critical pedagogy of internationalization that address some of the challenges identified in this dissertation and develop students' identities, critical thinking skills with a comparative perspective, intercultural communication, cultural competence, and social justice.
