A Comparison of Components of Written Expression Abilities in Learning Disabled and Non-Learning Disabled Students at Three Grade Levels. Learning Disability Quarterly, 3(4), 46-53. doi: 10.2307/1510674http://hdl.handle.net/11244/25554Although written language plays a critical role in academic success, little empirical evidence exists on the normal development of processes involved in producing written products. Even less is known about the writing performance of LD children. This study empirically compared the written products of LD and normal students at three grade levels on The Test of Written Language. Results showed that LD subjects scored significantly lower than normal subjects on most written expression abilities, especially in the mechanical tasks of spelling, punctuation, and word usage.en-USA Comparison of Components of Written Expression Abilities in Learning Disabled and Non-Learning Disabled Students at Three Grade LevelsResearch Article10.2307/1510674false
