CDT Equipment Operation & Maintenance 3 — Questions and Answers
Question 1: A therapist is setting up a tablet for a dyslexia session and needs to enable accessibility features. Which setting MOST directly supports a student who struggles with visual tracking across text?
- Auto-rotate screen
- Guided Access with a single-line reading ruler overlay (Correct answer)
- Dark mode color inversion
- Reduce motion setting
Correct answer: Guided Access with a single-line reading ruler overlay
Guided Access combined with a reading ruler overlay restricts the student to a single line of text, directly supporting visual tracking deficits.
Question 2: During a dyslexia therapy session, the speech-to-text software repeatedly misrecognizes a student's words. What is the most effective corrective maintenance action?
- Switch the student to handwriting only
- Retrain the software's voice profile using the student's speech patterns in a quiet environment (Correct answer)
- Increase screen brightness
- Disable spell-check within the software
Correct answer: Retrain the software's voice profile using the student's speech patterns in a quiet environment
Retraining the voice profile with the specific student's speech in a quiet environment improves recognition accuracy for that user.
Question 3: Which practice BEST maintains the accuracy of a handheld digital timer used during timed reading fluency assessments?
- Resetting it only at the start of each school year
- Checking it against a reference clock before each assessment and replacing batteries on a scheduled cycle (Correct answer)
- Running it continuously to prevent battery drain from repeated start/stop cycles
- Calibrating it using the student's subjective sense of elapsed time
Correct answer: Checking it against a reference clock before each assessment and replacing batteries on a scheduled cycle
Regular comparison to a reference clock and scheduled battery replacement ensures timing accuracy for valid fluency data.
Question 4: A therapist plans to use a document camera to display decodable text for a group session. Which setup step is essential BEFORE students arrive?
- Leaving the camera unattended and on overnight to warm up
- Confirming focus, brightness, and projection alignment on the display surface (Correct answer)
- Removing the camera lens cover after students sit down
- Setting the camera to record all student interactions automatically
Correct answer: Confirming focus, brightness, and projection alignment on the display surface
Pre-session setup ensures no instructional time is lost and that the image is legible for all students, especially those with visual sensitivity.
Question 5: An e-reader used in dyslexia therapy allows font customization. Which combination of settings is MOST supported by research for students with dyslexia?
- Small font, serif typeface, narrow line spacing
- Larger font size, dyslexia-friendly sans-serif typeface, increased line and letter spacing (Correct answer)
- Justified alignment with small margins and default spacing
- Italic font style with standard spacing to add visual variety
Correct answer: Larger font size, dyslexia-friendly sans-serif typeface, increased line and letter spacing
Research supports larger, open sans-serif fonts with expanded spacing to reduce visual crowding and improve letter discrimination for readers with dyslexia.
Question 6: When a therapist discovers that tactile letter manipulatives have sharp edges after being dropped, what is the correct response?
- Sand down the edges and continue using them in the same session
- Remove the damaged pieces immediately and replace them before the next session (Correct answer)
- Use masking tape over the sharp edges temporarily
- Return the pieces to the bin and note it in the session log for later
Correct answer: Remove the damaged pieces immediately and replace them before the next session
Sharp manipulatives pose a safety risk and should be removed from active use and replaced prior to the next session.
Question 7: Which routine best ensures that a laptop's assistive software remains functional across multiple dyslexia therapy sessions?
- Installing all available updates immediately during a student session
- Scheduling software updates and restarts outside of session hours and keeping a session-ready checklist (Correct answer)
- Disabling all automatic updates to avoid unexpected changes
- Relying on students to report software problems during activities
Correct answer: Scheduling software updates and restarts outside of session hours and keeping a session-ready checklist
Scheduling updates outside session hours prevents mid-session disruptions while keeping software current and secure.
