Building Word Knowledge, Learning Strategies, and Metacognition with the Word-Knowledge E-Book.

Area of Science:

• Educational Technology
• Cognitive Psychology
• Learning Science

Background:

• Reading comprehension difficulties in children often stem from poor monitoring of understanding and inadequate strategy use.
• Metacognitive skills, including accurate self-assessment of knowledge and employing repair strategies, are crucial for effective reading.
• Developing word knowledge calibration and strategy use is essential for improving overall reading comprehension.

Purpose of the Study:

• To assess the impact of the Word Knowledge e-Book (WKe-Book) on children's word knowledge calibration, strategy use, and overall word knowledge.
• To determine if the WKe-Book intervention improves students' reading comprehension and vocabulary acquisition.
• To investigate the synergistic effect of the WKe-Book and a book club format on metacognitive skills and reading performance.

Main Methods:

• A randomized controlled trial involving 603 third to fifth graders in Arizona.
• Intervention group used the WKe-Book, a tablet-based choose-your-own-adventure reading tool with embedded feedback.
• Students were assigned to immediate WKe-Book treatment or delayed control, with within-classroom variations of book club participation versus independent reading.

Main Results:

• The WKe-Book intervention demonstrated significant positive effects on students' word knowledge, word knowledge calibration, and strategy use.
• Improvements in these metacognitive skills predicted enhanced performance on standardized reading comprehension and vocabulary assessments.
• Students participating in the weekly book club alongside the WKe-Book showed greater improvements compared to those reading independently.

Conclusions:

• Technology-based tools like the WKe-Book can effectively enhance metacognitive skills crucial for reading comprehension.
• The WKe-Book supports word learning, calibration, and strategy use, offering advantages over traditional paper-based materials.
• Integrating interactive digital tools with collaborative activities like book clubs can maximize learning gains in reading education.
