Syntactic complexity in written expression of LD college writers

Area of Science:

• Linguistics
• Education
• Psychology

Background:

• Learning disabilities (LD) can impact academic writing skills.
• Assessing syntactic complexity is crucial for evaluating writing quality.
• The Syntactic Density Scoring (SDS) procedure offers a method for quantifying writing complexity.

Purpose of the Study:

• To compare the syntactic complexity of writing between college students with and without LD.
• To evaluate the effectiveness of the Syntactic Density Scoring (SDS) procedure in differentiating writing abilities.

Main Methods:

• Expository essays were collected from 33 LD and 33 non-LD college students.
• Essays were scored holistically and then analyzed using the Syntactic Density Scoring (SDS) procedure.
• The SDS procedure utilized 10 weighted variables to assess syntactic complexity.

Main Results:

• No significant differences were found in the overall SDS or corrected SDS (CSDS) scores between LD and non-LD writers.
• LD writers showed significant differences in subordinate clauses per T-unit and main clause word length.
• Factor analysis confirmed SDS provides supplementary information to existing writing assessment tools.

Conclusions:

• Overall syntactic complexity may not differ significantly between LD and non-LD college writers.
• Specific measures within the SDS procedure are more sensitive to differences in writing complexity.
• The SDS procedure shows potential for refining writing assessment, with recommendations for future improvements.
