Profile Analysis of Students with Reading Comprehension Difficulties

Struggling students were classified into five distinct types based on their mastery profiles across literal, inferential, and evaluative comprehension, highlighting that intervention approaches should not be 'one-size-fits-all'. For example, Type 1 students (18%) lacked mastery in all three comprehension levels, indicating a need for comprehensive intervention. Type 3 students (62.8%), the largest group, specifically struggled with literal comprehension. Interestingly, some struggling students demonstrated more difficulty with literal comprehension than with inferential or evaluative comprehension, which contradicts the common assumption of a straightforward hierarchical progression of these skills. These individualized cognitive profiles, derived from the diagnostic model, provide educators with detailed information on specific strengths and weaknesses, enabling targeted and effective instructional strategies.

The study successfully identified cognitive profiles of students with reading comprehension difficulties, revealing nuanced mastery patterns beyond a simple 'mastered/not mastered' dichotomy. Evaluative comprehension proved to be the most challenging for all student groups. A key finding was that some struggling readers face greater challenges with literal comprehension than with inferential or evaluative comprehension. This calls for a re-evaluation of instructional hierarchies and emphasizes the need for tailored interventions. The cognitive diagnostic model offers a powerful tool for diagnosing individual learning needs, moving beyond traditional assessment to inform personalized instruction. Practical implications include educators adopting nuanced teaching methods, utilizing comprehensive assessment tools (e.g., adaptive reading software), and receiving specialized training in interpreting diagnostic data to implement individualized learning plans for students with reading comprehension difficulties.

Reading comprehension is crucial for academic success, and difficulties in this area can significantly impact learning. This study focuses on understanding the cognitive profiles of elementary sixth-grade students struggling with reading comprehension. It categorizes reading comprehension into literal, inferential, and evaluative levels, where literal comprehension involves recalling explicit information, inferential comprehension requires interpreting implicit meanings, and evaluative comprehension extends to relating text to prior knowledge. The cognitive diagnostic model is employed to assess students' mastery of specific cognitive attributes, providing precise feedback for intervention, aligning with mandates like the Every Student Succeeds Act (ESSA) in the U.S. for diagnostic reading assessments.

The study utilized a fusion model (NC-RUM), a cognitive diagnostic model designed to identify students' mastery of cognitive attributes. A Q-matrix, which maps test items to specific cognitive attributes, was developed and validated by subject matter experts. The participants included 1000 sixth-grade students from 28 elementary schools across various regions in South Korea. Students with incomplete responses or certain disabilities were excluded. Participants were categorized into 'good' (top 19.8%), 'average' (middle 63.1%), and 'struggling' (bottom 17.1%) readers based on their reading comprehension test scores. The test items, selected from the National Assessment of Educational Achievement (NAEA), were aligned with seven validated cognitive attributes related to literal, inferential, and evaluative comprehension, such as 'comprehension of words and sentences' or 'evaluation of paragraphs'.

Analysis using the fusion model revealed distinct patterns of cognitive attribute mastery across all students and between different groups. For all students, 'comprehension of following contents' (inferential) showed the highest probability of mastery (0.83), while 'evaluation of paragraphs' (evaluative) had the lowest (0.399). This indicates that evaluative comprehension is generally the most challenging. When examining groups, good students consistently showed the highest mastery across all attributes. Average students mastered literal and inferential comprehension but were 'unsure' about evaluative attributes. Struggling students showed the lowest mastery across all attributes, with a critical finding being their significant difficulty with literal comprehension attributes, challenging the traditional linear hierarchy of comprehension skills where literal comprehension is assumed to be the easiest.
