Decoding, knowledge, and strategies in comprehension of expository text

Area of Science:

• Educational Psychology
• Reading Comprehension
• Social Science Education

Background:

• Understanding factors influencing text comprehension is crucial for academic success.
• Previous research highlights the importance of word-level skills, background knowledge, and reading strategies.
• The interplay between these factors, particularly in social science texts for adolescents, requires further investigation.

Purpose of the Study:

• To determine the relative contributions of decoding, topic knowledge, and strategic processing to social science text comprehension.
• To investigate the interaction between topic knowledge and strategic processing in influencing comprehension.
• To explore whether strong higher-level processing can compensate for poor word-level decoding skills.

Main Methods:

• Multiple regression analysis was employed to assess the predictive power of different factors on comprehension.
• Analysis of variance (ANOVA) and post-hoc tests were used to examine group differences and interactions.
• A sample of Norwegian junior high school students was assessed for decoding skills, topic knowledge, strategy use, and text comprehension.

Main Results:

• Prior topic knowledge was the most significant predictor of social science text comprehension.
• Word decoding skills and the use of organization and monitoring strategies also significantly contributed to comprehension.
• No significant interaction was found between topic knowledge and strategic processing.

Conclusions:

• Students with strong prior knowledge demonstrate superior comprehension of social science texts.
• Effective strategy use and robust decoding skills are important, but substantial topic knowledge can mitigate the impact of poor decoding.
• The findings suggest that interventions aimed at building background knowledge may be highly effective in improving reading comprehension in social science.
