Predicting Reading Difficulty in First Grade Using Dynamic Assessment of Decoding in Early Kindergarten: A...

Area of Science:

• Educational Psychology
• Developmental Psychology
• Literacy Research

Background:

• Early identification of reading difficulties is crucial for timely intervention.
• Traditional static prereading measures have limitations in predicting future reading success.
• Dynamic assessment offers a more responsive approach to evaluating learning potential.

Purpose of the Study:

• To compare the classification accuracy of static prereading measures versus early dynamic assessment reading measures.
• To evaluate the effectiveness of two different dynamic assessment strategies (onset-rime vs. sound-by-sound).
• To determine if combining static and dynamic measures enhances classification accuracy.

Main Methods:

• Administered static prereading measures to 600 kindergarten students.
• Applied dynamic assessments (onset-rime or sound-by-sound) to the same students.
• Assessed reading ability at the end of first grade using multiple measures.

Main Results:

• Dynamic assessments showed significantly higher classification accuracy than static measures.
• Both dynamic assessment strategies yielded comparable classification accuracy.
• Static measures had lower sensitivity (<80%) and specificity (33%-51%).
• Dynamic assessments demonstrated high sensitivity and specificity (>80% for most groups).
• Combining static and dynamic measures did not improve accuracy over dynamic assessments alone.

Conclusions:

• Dynamic assessment is a promising tool for identifying young children at risk for reading difficulties.
• Dynamic assessment provides superior classification accuracy compared to traditional static measures.
• Further research into dynamic assessment strategies can refine early reading intervention.
