Introduction

The definition of students with SEN which we adopt refers to those students who have significantly greater difficulty in learning than the majority of students. It is adopted with reference to the following SEN types as classified in DSM-5:

*Despite the fact that color blindness is not regarded as a special educational need in Hong Kong (Education Bureau, 2018), we consider colour blindness as a type of visual impairment, comply with the principle of reaching out to the last, the least and the lost (3L) who are under-served by the traditional tertiary education system.

Hearing Impairment (HI)

A disorder in any part of the auditory system will affect the hearing ability, thus affecting the speech and communication abilities. A student with hearing thresholds higher than 25dB can be regarded as having HI. The severity of HI is categorized into five different degrees of hearing threshold (measured in dB):

Speech and Language Impairment (SLI)

Language is the building block of knowledge and an important tool for thinking and communication. School-aged students with SLI cannot communicate with others effectively. Their academic performance, emotions and social development will also be affected. The common types of SLI amongst school-aged students are subdivided into four major categories:

  1. Articulation Problem
    Articulation problem refers to mispronunciation of words due to various causes to the extent that other people cannot understand what is being said, such as mispronouncing “say” as “day”.
  2. Language Problem
    Children may fail to understand fully the information conveyed in a message, which leads to misunderstanding or even communication breakdown. Children with weak organization skills or limited vocabulary would have difficulties in conveying their messages.
  3. Fluency Problem
    Fluency problem, also known as stammering, refers to the condition in which the flow of speech is interrupted by repetition of syllables or words, or prolongation of sounds, or the speech rate is too fast or too slow, or blocks.
  4. Voice Problem
    Voice problem refers to hoarseness, loss of voice, excessively high/low pitch, difficulties in controlling the loudness of voice, hyper- or hypo-nasality, etc. due to various causes.

Specific Learning Difficulties (SLD)

SpLD in reading and writing, also known as dyslexia, is the most common type of SpLD. Children with SpLD in reading and writing, despite having normal intelligence and formal learning experiences, are unable to read, spell and dictate words accurately and fluently. Such conditions are severe and persistent. Generally speaking, they have poorer literacy skills and weaker cognitive abilities in relation to reading and writing.
