The racial/ethnic disparities and average declines in science, technology, engineering, and mathematics (STEM) motivation during adolescence are worrisome. Although STEM motivational beliefs are theorized to function in conjunction with one another, the unique patterns and how they change over time for different racial/ethnic groups remain…

This longitudinal study explores three research questions. First, what is the prevalence of math and science gender stereotypes among high school students, their parents, and teachers? Second, are parents' and teachers' gender stereotypes related to adolescents' stereotypes? And third, are adolescents' gender stereotypes associated with their math…

Integrating situated expectancy-value and family systems theories, the current study tested the extent to which Latinx adolescents' 9th-grade school-related science conversations with parents and older siblings/cousins positively predicted their 10th-grade science ability self-concepts and task values. We also tested whether these links were…

This study examined the associations between parental involvement in adolescents' organized after-school activities and adolescents' motivational beliefs. Data were reported by 231 Mexican-origin and European American adolescents who participated in an organized after-school activity (57% female, M[subscript age] = 12.37, SD = 0.54) and their…

This cross-sectional study examined why Latinx adolescents participated in organized activities in comparison to White adolescents. This study, utilizing phone interviews for surveying, included 236 participants (53% female) of Latinx (64%) and White (36%) descent from four Southwest middle schools to answer these overarching questions: (1) What…

Math and science motivational beliefs are essential in understanding students' science, technology, engineering, and math (STEM) achievement and choices in high school and college. Drawing on the Eccles' expectancy-value theory and Arnett's emerging adulthood framework, this study examined the relations among high school students' motivational…

Based on the Eccles' expectancy-value theory, the objectives of this study were (1) to examine the longitudinal relations between Latino parents' science beliefs, parents' science support, and high school students' science motivational beliefs, and (2) to test whether these relations varied by familism values and adolescent gender. Multi-informant…

Families are theorized to influence adolescents' participation in skill-based after-school activities, but research has focused on the role of parents while neglecting the role of siblings. Siblings might be especially critical for Mexican-origin youth, the fastest growing youth population in the United States, due to a high value of family as…

Opportunities for collaborative learning reflect positive peer processes that have strong implications for adolescents' developmental experiences in afterschool programs (ASPs). However, collaborative learning, which involves considering multiple viewpoints and coordinating actions with peers to accomplish a shared goal, is often difficult for…

In this study, we identified (1) subgroups of youth during middle childhood who displayed distinct profiles of social emotional learning (SEL) skills including cooperation, prosocial behaviors, work habits, emotion regulation, and self-control; and (2) how these profiles predict longitudinal academic and social functioning during early…

This study explores ways to support girls of color in forming their senses of selves in science, technology, engineering, and math (STEM) during the middle school years. Guided by social practice theory, we analyzed a large data set of survey responses (n = 1,821) collected at five middle schools in low-income communities across four states in the…

Individuals are at an increased risk to drop out of the STEM pipeline if they are female or Latino, and during certain periods including high school. Families are a potential untapped resource of support for high school students. Based on the expectancy-value model, we examined if a variety of parental behaviors predicted students' ability…

International studies suggest that the U.S. ranks below many Asian and European countries in the 21st century in terms of mathematics and science achievement. Few have looked beyond the classroom to understand these differences. Absolute and relative time spent in various out-of-school time (OST) activities may provide one explanation. This study…

Organized activities have been found to provide positive experiences for Latino adolescents to develop confidence and learn critical life skills; however, these programs are sometimes a context where youth encounter negative experiences related to ethnic/racial microaggressions (ERMs). This qualitative study explores the types of ERMs that…

Youth out-of-school time (OST) programs and activities can provide developmental benefits for participating youth. Yet little research has examined the contextual predictors of youth OST participation. To address this issue, we examined a collection of child-, family-, school-, and neighborhood-level characteristics as predictors of OST…
