Flipped classrooms are implemented in more schools each year, particularly in courses requiring increased teacher guidance for mastery. While a foundation of research related to pedagogy and academic outcomes exists, research is limited surrounding student perceptions of the social and learning culture during flipped learning. The purpose of this study was to explore high school math students' lived experiences of flipped learning related to content and instruction, critical thinking, and collaboration and interactions. A phenomenological design was employed using a conceptual framework combining cognitive load theory, sociocultural learning theory, and schema theory. Students from two public high schools in the Midwest participated. Seven students participated in interviews, and nine students participated in two focus group discussions. Data analysis involved in vivo coding of transcribed interviews and focus groups. Key results included students' perceptions of increased engagement and interactions, as well as more in-depth learning in flipped environments. Increased critical thinking was related to both instructional strategies employed and students' ability to self-regulate learning. Concepts of peer collaboration shifted as students viewed learning environments and sources of expertise as more extensive in the flipped environment. This study contributes to positive social change by providing educators and researchers with a deeper understanding of the importance of ensuring students are competent in using social technology tools that encourage students to interact both socially and academically in order to help them become more self-directed learners.
