The purpose of this study was to analyze the impact of Flipgrid-based discussion activities with student-selected nonfiction texts on middle school students' motivation to read. The study investigated how teacher training affected teachers' comfort and confidence in using Flipgrid. While various discussion-based activities have been used with students, including Flipgrid, very little research has been done on its use with middle school students. Following a qualitative research design, this study obtained teacher perceptions through open-ended interviews on their Flipgrid experience and training and students' reading motivation. Student perceptions on Flipgrid, reading motivation, and student-selected texts were obtained through a Google form survey. Main findings indicated high teacher confidence due to the training they received and positive perceptions of Flipgrid-based discussion activities and student-selected text on students' reading motivation. Overall student perceptions were mostly positive about using Flipgrid and reading choice. Conclusions and implications showed positive effects with comprehensive training, which could be used with teachers training other teachers. With adequate training, teachers may be able to utilize student-centered learning, such as Flipgrid and student choice, to positively impact students' motivation to read.
