The Westminster Instructional Model integrates principles from the New Art and Science of Teaching and the Marzano Academy Instructional Model to establish a genuinely competency-based instructional framework. This synthesis of two research-backed methodologies results in a comprehensive approach to teaching and learning. For each element within the instructional model, Marzano Resources has crafted a corresponding Folio. These Folios provide a summary of the research validating the element's effectiveness, elaborate on the strategies it entails, and include an array of downloadable resources. These resources feature classroom examples, reproducible materials, and scales for teachers to self-assess their proficiency in each element, enhancing instructional practice and professional development.
