Abstract: This thesis utilizes multilevel growth curve modeling to examine the
impact of socioeconomic status (SES) and classroom environments on children's lexical
development from the fall of preschool to the spring of kindergarten. Fitting with prior
research finding that macro measures of SES (i.e., mother's highest level of education and
family income) is predictive of children's lexical ... read moreabilities, this study found that both
mother's highest level of education and family income were predictive of children's initial
level of lexical ability, but not changes in their abilities. This study also found that
measures of classroom environment, specifically the Concept Development and Quality of
Feedback subscales of the Classroom Assessment Scoring System (CLASS) predicted children's
initial level of lexical abilities, but not changes in in lexical development across time.
Findings and limitations are explored.
