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

Introduction

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

Hypotheses
Path Model
• Direct teacher expectancy effects on ending
achievements (Path 4)
– stronger in classrooms in which expectancy -related
cues were salient to children

• Indirect, or child-mediated pathways to teacher

(operating through the mediating variable of

– critical to fit of model in classrooms in which

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

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

Asked to indicate how well they thought
they would perform in reading by the end

• Scores reversed to correspond with high
achievement expectations

Measures:
Children’s Reading Achievement

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

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)

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)

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

– 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

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
