• Complete written tasks in a slow or labored manner.
• Frequently need help during the completion of a written assignment.
• Often seek praise and reassurance during written assignments.
![Page 20: Composition of Students with Disabilities. Learning Disabilities: Typically Disruption or Maturational Delay Language skills Motor skills Uneven performance.](https://reader036.fdocuments.in/reader036/viewer/2022062301/5697bf811a28abf838c85343/html5/thumbnails/20.jpg)

![Page 22: Composition of Students with Disabilities. Learning Disabilities: Typically Disruption or Maturational Delay Language skills Motor skills Uneven performance.](https://reader036.fdocuments.in/reader036/viewer/2022062301/5697bf811a28abf838c85343/html5/thumbnails/22.jpg)
Language Based Learning Disabilities may include difficulty with the following:
• Expressing ideas clearly, as if the words needed are on the tip of the tongue but won't come out. What the student says can be vague and difficult to understand (e.g., using unspecific vocabulary, such as "thing" or "stuff" to replace words that cannot be remembered). Filler words like "um" may be used to take up time while the student tries to remember a word.
• Learning new vocabulary that the student hears (e.g., taught in lectures/lessons) and/or sees (e.g., in books)
![Page 23: Composition of Students with Disabilities. Learning Disabilities: Typically Disruption or Maturational Delay Language skills Motor skills Uneven performance.](https://reader036.fdocuments.in/reader036/viewer/2022062301/5697bf811a28abf838c85343/html5/thumbnails/23.jpg)
• Understanding questions and following directions that are heard and/or read
• Recalling numbers in sequence (e.g., telephone numbers and addresses)
• Understanding and retaining the details of a story's plot or a classroom lecture
• Reading and comprehending material
• Learning words to songs and rhymes
• Telling left from right, making it hard to read and write since both skills require this directionality
![Page 24: Composition of Students with Disabilities. Learning Disabilities: Typically Disruption or Maturational Delay Language skills Motor skills Uneven performance.](https://reader036.fdocuments.in/reader036/viewer/2022062301/5697bf811a28abf838c85343/html5/thumbnails/24.jpg)
• Letters and numbers
• Learning the alphabet
• Identifying the sounds that correspond to letters, making learning to read difficult
• Mixing up the order of letters in words while writing
• Mixing up the order of numbers that are a part of math calculations
• Spelling
• Memorizing the times tables
• Telling time

Auditory Perception
• Auditory perception-Interpreting what is heard
• Phonological awareness
• Auditory discrimination

![Page 26: Composition of Students with Disabilities. Learning Disabilities: Typically Disruption or Maturational Delay Language skills Motor skills Uneven performance.](https://reader036.fdocuments.in/reader036/viewer/2022062301/5697bf811a28abf838c85343/html5/thumbnails/26.jpg)
Speech or Language Impairments
• Speech disorders- deviates significantly from the speech of others.
• Articulation, Voice, Fluency
• Language disorders- comprehension, and/or use of spoken, written and other symbol systems is impaired or does not develop normally.
• Receptive language• Expressive language• Form, content, function
![Page 27: Composition of Students with Disabilities. Learning Disabilities: Typically Disruption or Maturational Delay Language skills Motor skills Uneven performance.](https://reader036.fdocuments.in/reader036/viewer/2022062301/5697bf811a28abf838c85343/html5/thumbnails/27.jpg)
Reading
Students may:
• Have difficulty with one or more subject areas.
• Have limited mastery of concepts.
• Have limited fund of information.
• Have limited expressive and receptive vocabulary.
• Display limited knowledge of word meanings.
• Do not understand special multiple meanings of words.
• Read significantly below level of text.

CAUSES:• Weak listening speaking and sight
vocabulary.• Weak contextual analysis skills.• Inability to apply same word in
different contexts.
