Supporting Teachers' Data-Based Individualization of Early Writing Instruction: An Efficacy Trial

Area of Science:

• Education
• Special Education
• Literacy Instruction

Background:

• Students with intensive early writing needs require specialized instructional support.
• Data-based instruction (DBI) is a framework that can be used to tailor instruction.
• Teacher professional development is crucial for effective implementation of instructional strategies.

Purpose of the Study:

• To evaluate the impact of a comprehensive professional development program on teachers' data-based instruction (DBI) for students with intensive early writing needs.
• To assess the effects of this professional development on teachers' knowledge, skills, and self-efficacy.
• To examine the influence of the intervention on student writing outcomes.

Main Methods:

• A multiyear, multisite randomized control trial involving 154 teachers (primarily special educators).
• Teachers were randomly assigned to a treatment group receiving 20 weeks of data-based instruction tools, learning, and coaching (DBI-TLC), or a control group.
• Student writing outcomes were compared between those receiving DBI from treatment teachers and those receiving usual instruction from control teachers.

Main Results:

• Treatment teachers demonstrated significantly higher data-based instruction knowledge and skills (d = 1.57) and self-efficacy (d = 0.94) compared to controls.
• Students taught by treatment teachers showed improved proximal and distal writing outcomes (d = 0.14–0.29) compared to control students.
• Intervention effects were consistent across various student characteristics, including grade, special education status, English learner status, and race/ethnicity.

Conclusions:

• Comprehensive professional development, including tools, learning, and coaching (DBI-TLC), is effective in enhancing teachers' data-based instruction.
• The intervention positively impacts student writing performance, highlighting the importance of supporting students with intensive learning needs.
• Findings support the efficacy and feasibility of DBI-TLC and offer implications for teacher training and professional development programs.
