The aim of this study was to use sociocultural perspectives to elaborate on Eccles' parent socialization model and create a culturally grounded, multidimensional model of parent support among Mexican-descent families. Given Latinx underrepresentation in science, technology, engineering, and mathematics careers, we focus on science as an important…

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…

Although previous literature indicates that parents and siblings each provide key support for Latinx adolescents' academic success, most studies have not considered how parents and siblings work as a system to support adolescents in science. Informed by theories on family systems and family influence on youth's achievement and education, this…

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…

High school underrepresented minority students in the US are at an increased risk of dropping out of the STEM pipeline. Based on expectancy-value theory, we examined if Latino students' perception of support from parents, siblings/cousins, teachers, and friends in 10th grade predicted their science ability self-concepts and values, which in turn…

Overweight youth are often socially marginalized and have fewer friends than their nonoverweight peers. Participation in organized activities may be one way to promote friendships for overweight youth. In this study, we used a large nationally representative sample to test whether two aspects of participation promoted friendships, namely the…

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…

Children's work habits at school include being a hard worker, turning in work on time, following classroom rules, and putting forward one's best effort. Models on youth character, noncognitive skills, and social-emotional learning suggest that self-management skills like work habits are critical for individuals' subsequent academic success. Using…

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…
