Multiple domains develop simultaneously and interact throughout infancy and early childhood. Although relationships between motor and language skills have been examined cross-sectionally during the first three years of life, little is known regarding the individual factors that influence the development of these domains as well as the relationship…

One of the earliest indications that a student may be interested in STEM paths is the students' own self-efficacy for science as well as how they may see themselves in a STEM career as part of their science self-identity (Schlegel et al., 2019).

As the cost of living continues to increase over time, many Americans are placing greater scrutiny on the financial choices they make. An area for such evaluation is if the outcomes of going to college continue to be worth the cost.

This study examines how affective (student-teacher relationships) and sociological factors (race) interact in educational settings to shape differential educational experiences for diverse subgroups. Studying these factors in isolation only partially explains the mechanisms that drive outcomes for students, especially those belonging to…
