Spelling rule usage among students with learning disabilities and normally achieving students

Area of Science:

• Educational Psychology
• Developmental Psychology
• Linguistics

Background:

• Learning disabilities (LD) significantly impact academic achievement, particularly in literacy skills.
• Spelling difficulties are a common characteristic of students with LD, affecting their educational trajectory.
• Understanding specific spelling deficits in LD is crucial for targeted interventions.

Purpose of the Study:

• To compare the spelling performance of students with LD to normally achieving peers.
• To investigate specific spelling rule deficits in students with LD, differentiating between reading ability.
• To explore the cognitive-linguistic underpinnings of spelling difficulties in learning disabilities.

Main Methods:

• Administered a spelling battery assessing phoneme-grapheme correspondence and suffix rule usage.
• Compared spelling performance across three groups: students with LD (poor readers/poor spellers; good readers/poor spellers) and normally achieving peers.
• Utilized same-age and younger normally achieving students as control groups.

Main Results:

• Students with LD performed significantly below same-age normally achieving peers on all spelling tasks.
• No significant differences were found between the two LD subgroups in primary analyses.
• Secondary analyses revealed specific difficulties with the past tense 'ed' rule and suffix spelling in LD groups.

Conclusions:

• Students with learning disabilities exhibit broad spelling deficits compared to their normally achieving peers.
• Specific rule-based spelling difficulties, particularly with suffixes and past tense markers, characterize LD.
• Further research into cognitive-linguistic factors is warranted to address these spelling challenges.
