The problem studied was the poor academic achievement of middle school students in the Commonwealth of the Northern Mariana Islands (CNMI). Research indicates that a growth mindset positively affects a student's academic achievement and motivation to learn. However, despite the importance of mindset in fostering student success and enhancing learning, mindset remains underexplored in the CNMI. The purpose of this generic qualitative study was to fill this gap in knowledge by investigating teachers' knowledge, perceptions, and practices concerning mindset in the CNMI. Three research questions examined teachers' knowledge and perceptions of mindset in the CNMI and how teachers described and demonstrated the use of mindset in their practices. Dweck's seminal work on mindset served as the conceptual framework. Social constructivism guided the study process. Qualitative data were collected from 15 purposively sampled teachers at a local CNMI middle school. Data were analyzed through categorization and codification, from which emerging themes were used to answer research questions. Results indicated that teachers in the local middle school have limited knowledge and inaccurate perceptions regarding the mindset concept. Accordingly, the analysis recommended the need for and served as the basis for the design of a professional development workshop about mindset for teachers throughout the CNMI to enhance teacher instruction and improve student learning, thus promoting positive social change.

Since the reveal of the Black-White achievement gap in 1966, leaders and policymakers have attempted to close the gap to no avail. The purpose of this explanatory sequential mixed methods study was to examine the relationships between self-efficacy, grit, and academic achievement of Black and White students. For the first two research questions,I sought to determine whether there were relationships between self-efficacy, grit, and academic achievement as defined by the PSAT 10 Reading or Math results. Students were administered self-efficacy and grit surveys to establish their corresponding self-efficacy and grit levels. A Pearson correlation analysis was performed to determine the bivariate relationships between participants' self-efficacy and grit levels and their 2021 PSAT 10 Reading and Math results. Statistical significance was discovered; specifically, a positive correlation existed between Black students, grit, and their academic achievement on PSAT 10 Math. For the final two research questions, I solicited students' perspectives of self-efficacy and grit and how they perceived the two constructs were associated with their academic success. Semi-structured focus group interviews were conducted to better explain student perspectives from their Phase 1 survey responses, which produced themes associated with self-efficacy and grit. Students shared how they perceived these traits impacted their academic achievement. Themes that emerged from students that were discussed in this study were the perception of the snowball effect, the power of teacher perceptions, failure as a motivator, the importance of hard work and being careful, and more. Additionally, recommendations to further investigate grit and other noncognitive factors as viable options to increase academic student achievement are provided.
