Development and validation of Teacher Intentionality of Practice Scale (TIPS): A measure to evaluate and scaffold teacher effectiveness

Abstract Teacher evaluation instruments frequently fail to support teacher growth and improvement—particularly in critical constructs surrounding pedagogical content knowledge that promote student growth and achievement. The current study details the development and validation of the Teacher Intentionality of Practice Scale (TIPS), an observational protocol designed to measure intentional teaching practices and provide support for teacher growth over time. Findings suggest that TIPS provides a valid and highly reliable research-based teacher observational instrument that also serves as a professional development model to help scaffold the growth and improvement of K-12 educators. This paper details the theoretical foundations of TIPS, reports reliability and validity measures (including both Exploratory and Confirmatory Factor Analyses), and discusses applications and implications of TIPS for teacher evaluation and professional development.
