The main purpose of this study was to produce an understanding and insight in order to inform and gain knowledge on the influence of growth mindset in a classroom setting. During this qualitative case study, the participants were observed in their classroom setting. Each participant had a diverse background in teaching. The participants were of different ages, different races, and a variety of ranges in their teaching experiences. The data was collected from classroom observations, lesson plans, and one-on-one interviews with the teachers and administrators. The teachers were grouped into three categories between K-2nd grade, 3rd-5th grade, and 6th-8th grade. This foundation of implementing growth mindset could help the students work through their challenges and mistakes instead of giving up so quickly.
