BRS Pediatric Visual Impairment Services 5 — Questions and Answers
Question 1: Which strategy is MOST effective when introducing a new environment to a student who is blind?
- Providing only a verbal description of the space
- Conducting a systematic tactile-kinesthetic exploration using the student's hands and body (Correct answer)
- Showing the student a floor plan diagram
- Having sighted peers guide the student through the space repeatedly
Correct answer: Conducting a systematic tactile-kinesthetic exploration using the student's hands and body
Systematic tactile-kinesthetic exploration allows the student to build an accurate cognitive map of the space through direct, hands-on interaction with landmarks and boundaries.
Question 2: A child with a visual field loss due to glaucoma has lost peripheral vision. Which reading accommodation would MOST directly compensate for this loss?
- Increasing font size significantly
- Reducing line spacing and using wider margins
- Using a typoscope or line guide to maintain place while scanning (Correct answer)
- Switching from print to braille immediately
Correct answer: Using a typoscope or line guide to maintain place while scanning
A typoscope or line guide helps students with peripheral field loss maintain their place on the page and isolate lines of text, compensating for reduced scanning ability.
Question 3: Under Part B of IDEA, the requirement that students with visual impairments receive instruction in braille unless the IEP team determines it is not appropriate is known as:
- The braille mandate
- The presumption of braille (Correct answer)
- The literacy equity clause
- The dual media requirement
Correct answer: The presumption of braille
The 'presumption of braille' in IDEA requires that braille instruction be provided or made available unless the IEP team, after a full evaluation, determines braille is not appropriate for the individual student.
Question 4: Which CVI characteristic involves a student's inability to attend to a visually complex scene even when individual elements are recognizable?
- Visual latency
- Visual complexity / visual crowding (Correct answer)
- Light gazing
- Difficulty with distance viewing
Correct answer: Visual complexity / visual crowding
Visual complexity in CVI refers to difficulty processing scenes with multiple elements; the brain cannot simultaneously parse all competing visual inputs, causing a breakdown in recognition.
Question 5: A secondary school student with low vision wants to participate in chemistry lab activities. The MOST appropriate role of the TVI is to:
- Excuse the student from lab participation for safety reasons
- Collaborate with the science teacher to adapt materials and identify appropriate optical aids or tactile models (Correct answer)
- Assign a para-professional to complete lab work on behalf of the student
- Recommend the student transfer to a school for the blind for science coursework
Correct answer: Collaborate with the science teacher to adapt materials and identify appropriate optical aids or tactile models
TVIs consult and collaborate with content teachers to provide access to the general curriculum through adaptations, optical devices, and tactile or auditory alternatives.
Question 6: Which assessment approach is MOST appropriate for evaluating the visual functioning of an infant suspected of having cortical visual impairment?
- Standard Snellen acuity chart testing
- Observation of visual behavioral responses to structured stimuli across multiple environments over time (Correct answer)
- Single-session ERG (electroretinogram) testing only
- Parent questionnaire completed at home without professional observation
Correct answer: Observation of visual behavioral responses to structured stimuli across multiple environments over time
CVI in infants is best assessed through systematic behavioral observation across multiple settings and sessions, as visual responses are highly variable and context-dependent.
Question 7: Which professional is primarily responsible for evaluating a child's independent living skills as part of the Expanded Core Curriculum?
- Occupational therapist only
- Teacher of students with visual impairments (TVI) (Correct answer)
- School counselor
- General education classroom teacher
Correct answer: Teacher of students with visual impairments (TVI)
While other professionals may contribute, the TVI holds primary responsibility for assessing and teaching all areas of the Expanded Core Curriculum, including independent living skills.
