Teacher fidelity in the Promoting Acceleration of Comprehension and Content Through Text (PACT) intervention varied. Teachers excelled at building background knowledge and teaching vocabulary but struggled with critical reading and knowledge application.
Area of Science:
- Educational Psychology
- Curriculum and Instruction
- Reading Comprehension Research
Background:
- Teacher fidelity, or adherence to intervention protocols, is crucial for evaluating educational programs.
- The Promoting Acceleration of Comprehension and Content Through Text (PACT) is a multicomponent intervention for middle and high school social studies.
- Understanding fidelity variations is key to improving the implementation of effective reading comprehension strategies.
Purpose of the Study:
- To assess teacher fidelity across different components of the PACT intervention.
- To identify specific instructional elements where teachers demonstrated high versus low adherence and quality.
Main Methods:
- Analysis of teacher fidelity data from multiple studies involving middle and high school social studies teachers implementing the PACT intervention.
- Evaluation focused on adherence to specified instructional components, including building background knowledge, teaching vocabulary, critical reading, and knowledge application.
Main Results:
- Teachers consistently exhibited high implementation fidelity and quality for building background knowledge (comprehension canopy) and teaching key content vocabulary (essential words).
- Conversely, consistently lower fidelity and quality of implementation were observed for critical reading and knowledge application components.
- These findings highlight differential adherence to intervention components despite specified materials and aligned practices.
Conclusions:
- Teacher fidelity within the PACT intervention is component-specific, with notable strengths in foundational comprehension and vocabulary instruction.
- Challenges in implementing critical reading and knowledge application components suggest areas for targeted professional development and intervention refinement.
- Optimizing teacher fidelity across all intervention elements is essential for maximizing student outcomes in social studies comprehension.
