This study applies psychological models of interest and motivation (i.e., a model of interest-development and selfdetermination theory) to the experiences of six preservice science Noyce scholars who participated in a teacher preparation program. The National Science Foundation's Noyce grant aims to incentivize mathematics and science majors to teach in high-needs school districts. Through this interview study, we sought to understand how Noyce scholars' pre-existing interests and their experiences in the Noyce program interact to develop individual commitments to teach in high-needs school settings. Case studies reveal that scholars had no prior experiences in high-needs schools, abstract ideas about teachers, students, and resources in these contexts, and varying degrees of initial connectedness to teaching in high-needs school settings. Scholars found that site visits to diverse high-needs schools (i.e., rural and urban) triggered their interest to teach in similar contexts.Preservice science teachers' emerging interest and level of commitment to teaching in high-needs schools following the teacher preparation program was dependent upon contextspecific mastery experiences and autonomy within their long-term clinical field experience. This study offers implications for teacher educators who are recruiting and preparing students to teach in high-needs school contexts.high-need schools, interest development, motivation, teacher preparation, teacher recruitment Science Education. 2019;103:875-899. wileyonlinelibrary.com/journal/sce © 2019 Wiley Periodicals, Inc. | 875 1.1 | Four-phase model of interest development Hidi and Renninger's (2006) four-phase model of interest development provides a theoretical foundation for understanding how teacher educators might spark preservice teachers' interests to teach in high-needs schools,and then proceed to fan the flames of that spark to develop those interests into a firmer commitment. Hidi and Renninger argued that "interest is the outcome of an interaction between a person and a particular content…. This means that interest is always content specific and not a predisposition that applies across all activities" (p. 112).Thus, in relationship to developing interest to teach science in high-needs schools, preservice science teachers must be provided with situational experiences of learning about and teaching science in high-needs schools. Interest, as it develops, passes through four phases. Interest development begins with a spark or triggered situational interest, which can be developed into a maintained situational interest if the appropriate fuel can be provided to sustain the initial spark and allow it to grow (Hidi & Renninger, 2006). Over time, maintained situational interest, with appropriate external supports, can become an emerging individual interest, which Hidi and Renninger described not only as a psychological state (the way that situational interest is conceptualized) but also as the "beginnings of a 876 | KIER AND CHEN
