Description¶

The article organizes the policy problem of co-teaching in value-added models as a set of options available to policymakers, building on earlier work that described the Full Roster Method. It frames co-teachers as teams, "with each teacher receiving equal credit for co-taught students," and positions the Full Roster-Plus Method as an improvement that removes the extra weighting of co-taught students while keeping their full weight with each teacher. The framework serves as a guide for policymakers and developers of value-added models choosing how to account for co-teaching.

Design Implications¶

Context¶

Requirements¶

• A value-added model in which teachers are credited for their students' achievement, with data identifying which students are co-taught and by which teachers

Constraints¶

• The empirical evidence reported comes from a single district, District of Columbia Public Schools

Target Learners¶

• K-12 students in co-taught classrooms in public school districts

Target Learning Objectives¶

• Accurate estimation of individual teacher contributions to student achievement growth in value-added accountability systems

Claims¶

• Frm Counts Cotaught Students More Than Once [+M]
• Frp Vs Frm Very Small Empirical Differences [+M]

Related Theories¶

• Three-method framework for accounting for co-teaching in value-added models
• Four options for accounting for co-teaching in value-added models

Examples¶

• Policymakers and model developers should use the Full Roster-Plus Method to account for co-teaching in value-added models
