PSI Instructional Technology & Tools 2 — Questions and Answers
Question 1: Which type of microphone is BEST suited for a public safety instructor who needs hands-free operation during practical demonstrations?
- Condenser boom microphone
- Lavalier (lapel) microphone (Correct answer)
- Dynamic handheld microphone
- Shotgun microphone
Correct answer: Lavalier (lapel) microphone
Lavalier microphones clip to clothing, allowing instructors to move freely and demonstrate techniques without holding a microphone.
Question 2: When projecting slides in a room with high ambient light, an instructor should select a projector with at least how many lumens for adequate visibility?
- 500–1,000 lumens
- 1,000–1,500 lumens
- 2,500–3,500 lumens (Correct answer)
- 5,000–7,000 lumens
Correct answer: 2,500–3,500 lumens
Rooms with significant ambient light typically require projectors rated at 2,500–3,500 lumens to maintain readable image brightness.
Question 3: A public safety instructor wants students to practice decision-making in a realistic fire scene without physical risk. The MOST appropriate technology is:
- Overhead transparency projector
- Immersive virtual reality (VR) simulation (Correct answer)
- Standard PowerPoint presentation
- Printed case study handout
Correct answer: Immersive virtual reality (VR) simulation
VR simulations create immersive, risk-free environments that replicate real emergency scenarios for decision-making practice.
Question 4: Which file format is MOST universally compatible when sharing presentation slides with students who may use different operating systems?
- .pptx
- .key
- .odp
- .pdf (Correct answer)
Correct answer: .pdf
PDF format preserves formatting and is viewable on all major operating systems without requiring specific presentation software.
Question 5: An instructor notices students are disengaged during a long lecture. Which instructional technology tool BEST restores active participation?
- Switching to a different font on slides
- Using an audience response system (clicker or poll) (Correct answer)
- Increasing slide transition animations
- Turning off the projector temporarily
Correct answer: Using an audience response system (clicker or poll)
Audience response systems prompt every learner to actively answer questions, immediately re-engaging the group.
Question 6: When recording instructional videos for asynchronous online training, what is the recommended maximum length to maintain adult learner engagement?
- 30–45 minutes
- 20–25 minutes
- 10–15 minutes (Correct answer)
- 5–6 minutes
Correct answer: 10–15 minutes
Research on adult e-learning shows engagement drops sharply beyond 15 minutes; segments of 10–15 minutes are considered optimal.
Question 7: Which accessibility feature should an instructor enable in recorded training videos to support hearing-impaired students?
- Picture-in-picture mode
- Closed captions or subtitles (Correct answer)
- Auto-play looping
- High-contrast color filter
Correct answer: Closed captions or subtitles
Closed captions provide a text transcript of spoken audio, making video content accessible to hearing-impaired learners.
