The heterogeneity in the developmental trajectories of math motivational beliefs (i.e., expectancies for success and subjective task value beliefs) was examined among Asian and Latinx male and female students from Southern California across Grades 8 through 10 (n = 2,710; 50% female; 85% Latinx; 15% Asian; M-age = 13.77). By conducting growth mixture modeling, we identified two classes of stable trajectories for expectancies for success; five classes of stable, decreasing, or increasing trajectories for interest and utility value; and three classes of stable, decreasing, or increasing trajectories for attainment value. The group comparisons demonstrated that variability exists in adolescents' motivational belief development at the intersection of their race/ethnicity and gender for some trajectories. For example, Latina adolescents were more likely to maintain moderate expectancies for success than high expectancies for success compared to Latino and Asian male adolescents, but Asian female adolescents did not differ in their level of expectancies for success from the two male groups. Also, we found Latina adolescents displayed smaller decreases in interest compared to Asian female adolescents and in utility value compared to Latino adolescents. The findings from the present study challenge traditional stereotypes in math and highlight positive motivational belief development in students who are marginalized in math (e.g., Latina adolescents).

Are motivated students less likely to express negative achievement emotions in math, and how do teachers impact such academic beliefs? Guided by the situated expectancy-value theory and the control-value theory, this study is interested in how teacher support influences students' negative affect in math through students' perception of teacher support and students' interest value (teacher-to-student transmission between and within classes). Thus, associations were modeled at the individual and classroom levels to investigate cross-level interactions. Using data from 1,429 students in grades 7-12 (49% males, 67% Hispanic Americans, 15% Asian Americans, 18% other racial/ethnic groups), cross-level indirect effects suggested an association of teacher-reported support for collaboration and cognitive support with decreasing negative affect through students' perception of teacher support and students' interest value. These associations were supported within but not between classes.

Social support has a well-documented impact on adolescent educational success. Nonetheless, there has been less focus on the relationship between social supports and educational attainment for Latinas. Using a sample of 138 Hispanic females (ages 25-31) from an ongoing longitudinal National Science Foundation (NSF)-funded study (2004-present), we identified key sources of social support (family, teachers, and peers) and types of social support (emotional, informational, and instrumental) in the educational pipeline of Hispanic females. We also examined the associations between social supports and their educational attainment. Through descriptive analyses, we found that family was perceived to provide the most support followed by peers and teachers in adolescence. Through regression analyses, we found that family support positively predicted their educational attainment. Our findings highlight the importance of family-rendered support for educational attainment while also expanding our understanding of the social support mechanisms for Hispanic females.

This study utilized growth curves and change models to understand the impact of student perceptions of teacher caring on the development of math motivation for an ethnically and linguistically diverse sample of adolescents in middle school (N = 1926) and high school (N = 1531). Using an expectancy-value framework, growth curves revealed declining math motivation for both middle school and high school cohorts. However, perceived teacher caring buffered against these declines and was positively associated with math self-efficacy and subjective task values. Change models revealed that perceived teacher caring at the beginning of the school year increased math motivation by the end of the year. The results shed light on the important role that student-teacher relationships play in influencing math motivation during adolescence.

Students' valuing of subject domains is an important contributor to students' educational success. As one avenue to foster students' valuing, social-cognitive motivational theories suggest that teachers might transmit their value beliefs to students through their instructional strategies. Accordingly, the current study examined the transmission of teacher's math value to students' math value via the content-related instructional strategy of cognitive support as reported by teachers and students. Using a longitudinal dataset of 1429 students (51% males, 68% Hispanic) and their 26 teachers (48% female), manifest-latent multilevel regression analyses showed some indication that teacher's endorsement of math valuing for their students, but not their personal value beliefs, might be associated indirectly with class average students' interest value through teacher's provision of cognitive support. Furthermore, teacher's reported cognitive support was related to the class average of students' value beliefs through class average students' perceptions of cognitive support, highlighting the importance of students' perceptions. © 2021 Elsevier Ltd

This study examined the longitudinal associations of Hispanic youths' 9th-grade math expectancy-values and their subsequent participation (course taking and advanced course taking), performance, and preparedness (high school graduation and university eligibility) across 9th to 12th grades. Gender moderation associations of expectancy-value and participation, performance, and preparedness were evaluated. Students' socio-demographic characteristics and previous math experiences (achievement and curricular track) were controlled. The study sample (n = 1,116) was 53% female, 46% English learner, and 84% low income. Males reported higher expectancy, interest, attainment, and cost values. Females completed more math courses and advanced courses, achieved stronger course grades, and were more likely to complete math preparation requirements for high school graduation and college. Associations of expectancy-value, and participation and performance were observed along with gender-moderated associations with preparedness. The odds of graduation preparedness were increased for females with high attainment value, whereas the odds of university preparedness were increased for males with high utility value.
