Summary • Path model of teacher expectancy effects on children’s achievement evaluated in sample of 376 elementary school children • Two moderators Kuklinsky, M. R. & Weinstein, R. S. (2001). Classroom & developmental differences in a path model of teacher expectancy effects. – classroom perceived differential treatment – Developmental differences • One mediator: children’s self -expectations • Findings: – Both moderators impacted effect of teacher expectancies Child Development, 72, 15541578 • Stronger effects of teacher expectancies in classrooms with more salient expectancy-related cues – Indirect (mediating) effect of children’s self-expectations limited to upper grades with high differential treatment • Moderate effect sizes found in classrooms with highly salient expectancy -related messages 1 Introduction 2 Purpose • Previous research: support for significant but modest teacher expectancy effects on children’s achievement. • Teacher expectancy effects likely to be larger when teacher expectations expressed in salient differences in student treatment that favor high over low achievers • Differences in educational opportunities, teacher-student interaction patterns, and classroom emotional climates that favor high- over low-achieving students can pose direct and indirect risks to children’s adaptation. • Children may internalize teacher expectations as their own • To examine two moderators – classroom differences in content of PDT – Developmental differences in children – Lead to performance- over mastery- oriented goals – Lead to use of superficial rather than deep strategies for learning new material – Teacher expectancy effects are likely to increase as child gets older and social comparison influence performance assessments 3 • One mediator (children’s late in the year expectations) • On a path model of teacher expectancy effecgts on elementary school children’s year-end reading achievement 4 Hypotheses Path Model • Direct teacher expectancy effects on ending achievements (Path 4) – stronger in classrooms in which expectancy -related cues were salient to children 1 • Direct teacher expectancy effects on children’s self-expectations (Path 5) 4 3 – stronger in classrooms in which expectancy -related cues were salient to children, and with increasing age Entering Reading Achievement E 2 Teacher Expectancies In Reading E 5 Children’s SelfExpectations in Reading E 6 Children’s SelfExpectations in Reading E • Indirect, or child-mediated pathways to teacher expectancy effects on ending achievement (operating through the mediating variable of children’s self expectation, Paths 5 & 6) – critical to fit of model in classrooms in which • differential treatment was salient • With increasing age. 5 6 1 Measures Method Participants Children’s perceptions of differential teacher treatment of high- and low - achieving students (Teacher Treatment Inventory: TTI) • 30 teacher behaviors toward high- and low achieving students • 376 children and 48 teachers – First graders – Third graders – Fifth graders – “Teacher makes R feel that R has not done the work well.” – “The teacher asks R if R understands the work.” – “The teacher asks R to lead activities.” • Up to 12 children per classroom – 4 high, 4 low, 4 moderate teacher expectancy students • Ethnicity: African American, Caucasian, Chicano/Latino, Asian American, Native American • 50% parents gave permission to participate in study • PDT score = high achieving score – low achieving score (-9 to +9) • Averaged across children within classroom • Classrooms median split into high and low PDT classrooms 7 8 Measures: Teacher Expectancy Measures: Child’s Self Expectancy • In fall, teachers rated children from 1 (poor) to 5 (outstanding) in expectations for year-end achievement in readintg • • • • 30 circles in a column Top of the class (at top of column) Bottom of class (at bottom of column) Asked to indicate how well they thought they would perform in reading by the end of the school year • Scores reversed to correspond with high achievement expectations 9 Measures: Children’s Reading Achievement 10 Procedures • Comprehensive Test of Basic Skills (CTBS) • Given at end of year • Scores measured in normal curve equivalents, derived from national percentile ranks • Entering achievement operationalized as last year’s achievement • Children completed High Achiever and Low Achiever versions of TTI in small group testing sessions in fall • Children completed self-expectations during individual testing sessions held in spring • Standardized achievement scores (from group testing) obtained from district 11 12 2 Analysis Results • Classrooms assigned to high- and low-PDT comparison groups and three age groups to test moderating hypotheses through separate analyses • Entering achievement significantly predicted ending achievement (Path 1) and teacher expectations (Path 2) at all grade levels – Failure to fit same path weights to more than one group = evidence of moderating effects – Magnitudes increased with age – Children’s achievement differences became more stable with age • Raw data standardized on entire sample to ease interpretation of parameters • Entering achievement significantly predicted children’s self expectations (Path 3) only in Grade 1 – Children’s self expectations transformed (square root) to stabilize variance • Support for hypotheses: small χ 2 statistic (relative to degrees of freedom) and large probability values considered desirable • If probability was between .05 and .10, and RMSEA = .05, fit considered adequate • R 2 used to assess effect size • Two stage hypothesis testing: – magnitude of relation declined with age only in high-PDT classrooms • Relation between children’s self -expectations and ending achievement (Path 6) did not – increase with age – dramatically differ between high- and low-PDT classrooms – Omnibus test of moderation for paths 4 and 6; one set of parameters did not work for all six groups; preliminary evidence for moderation 13 – Series of focused comparisons • Dramatic increase in R2 values for ending achievement over elementary school years – Related to increasing stability of children’s achievement differences. Moderating effects 14 Magnitude of effects • Grade level differences moderated strength of direct teacher expectancy effects on ending achievement (Path 4). • Teacher expectations had practical importance for models of children’s ending achievement in Grade 1 and Grade 3 highPDT classrooms – Declined from Grade 1 to Grade 5 – As path 1 and path 5 became stronger • In later grades, teacher expectations had relatively strong sustaining effects on children’s achievement differences • In earlier grades, teacher expectations had relatively strong self -fulfilling prophecy effects. – Effects largest in Grade 1 (10% - 12% explained variance) 15 16 Teacher Expectancy and Child’s Self-expectations Expected class rank Children’s Self-expectations • Stronger in high- PDT classrooms, particularly in higher grades • Teacher expectancy effects on children’s selfexpectations (Path 5) increased with age, but only when performance cues were salient • In early and middle grades, children’s selfexpectations remained independent of teacher expectations (after controlling for entering achievement levels) • Effect size = moderate in Grade 5 high- PDT classrooms (additional 9% of explained variance) 9.00 7.00 5.00 3.00 1.00 Grade 1 Grade 3 Grade 5 High PDT Low PDT Classroom environment 17 18 3 Indirect child-mediated teacher expectancy effects on ending achievement Self-Expectations as Mediators • Hypothesis: child-mediated pathway would be critical to model fit in high- PDT classrooms and with increasing age. • Partial support: removing path 5 significantly hampered fit of model 1 .75*** .01 – direct effects – indirect teacher expectancy effects operated through mediator of child’s self expectations (e.g., Grade 5 high-PDT classroom) – Indirect effects not needed in Grades 1 and 3 classes, regardless of PDT climate • Indirect effects: magnitude small, except in Grade 5 high PDT classroom Entering Reading Achievement Teacher Expectancies In Reading 2 .60*** E 4 3 5 Children’s SelfExpectations in Reading .38*** E .19*** 6 Children’s SelfExpectations in Reading .09* E E Figure 2. Path model results for Grade 5 High PDT classroom 19 20 Strengths, Limits, and Future Directions Discussion • Findings provided strong support that both classroom environment and grade-level differences moderated the strength of direct and indirect teacher expectancy effects. • Variability in effect size was related to differences in the classroom differential treatment environment and children’s age • Strengths – Longitudinal – Effects of teacher expectancy after controlling for entry achievement • Limits – Strongest direct effects of expectancy -related messages and ending achievement in Grade 1 in all environments – Similar magnitude of effects in high-PDT Grade 3 classrooms – Small sample size – Not experimental design • Future: – Need for explicit attention to moderators, mediators, and multiple outcomes in expectancy research: “to what extent and under what conditions?” • Question: role of teacher expectations in sustaining or preserving, but not adding to, differences in children’s entering achievement 21 22 4
