Scientific Study of Education Process for developing and evaluating theories (Shavelson, Townes and the Committee on Scientific Principles for Education Research, 2002) 1. Pose significant research questions 2. Build integrated theories 3. Test theories 4. Evaluate generalizability
Stage 1: Pose a Significant Question What are the mechanisms through which classrooms exert their influence on children’s development?
Stage 2: Build a Theory of Effective Classrooms • Theories of effective classrooms • The CLASS Framework (Hamre & Pianta, 2007) • Proximal processes • Integrates literature • Direct investigation
Integrating Domains of Classroom Interactions • Emotional Support • Attachment theory • Self-determination theory • Classroom Organization • Self-regulation • Instructional Support • Cognitive and language development
Direct Investigation • The COS/CLASS Observation System • Description • Reliability • Validity

Examining Generalizability Pre-k-3rd grade 3244
Results • Standardized Factor Loadings • Ranged from .60-.96 • Indices of Fit • 13/18 above .90 • None below .84
Refuting the 3 Domains • A one-domain theory • Fit was substantially worse than 3 Domain • A two-domain theory • Fit was substantially worse than 3 Domain
Conclusions • An important question for education research is What are the mechanisms through which classrooms exert their influence on children’s development? • The CLASS Framework proposes an integrative theory that classroom interactions comprise three domains • Evidence of three domains of classroom interactions received general support based on standardized observations of classroom interactions • These three domains were found in PK, Kindergarten, 1st grade and 3rd grade classrooms
Discussion • More refined theoretical understanding of classroom effects • Tool to observe interactions • Guidance for further research • Ultimately, direction for intervention
