Why We Chose Audio Over Video
Looking for a video-free alternative to platforms like IRIS Connect? Video lesson recording creates barriers - teachers feel self-conscious, setup is complex, and privacy concerns multiply. Starlight takes a different approach: audio-only recording that captures what matters most.
The Video Problem
Teachers feel self-conscious being recorded on video
Equipment setup is complex and time-consuming
Students and parents have privacy concerns
Audio captures teaching quality without the barriers
Why Audio-First is Better for Teachers
Most teaching quality indicators can be measured through audio alone
What Audio Captures
- Questioning techniques and wait time
- Clarity and structure of explanations
- Teacher vs student talk time
- Classroom discourse patterns
- Checking for understanding
- Scaffolding and modelling
Analyzing the quality of classroom talk is central to educational research and improvement efforts.— Kelly et al., Educational Researcher (2018)
Focus on Teaching, Not Performance
Without video, teachers can focus on what they say and how they interact with students - not how they look. This removes a major barrier to honest self-reflection.
Video vs Audio Recording
See why teachers prefer the audio-first approach
Video Recording
- Requires special equipment and setup
- Teachers change behaviour when filmed
- Student privacy and consent issues
- Large file sizes and storage needs
- Focus shifts to appearance
- Higher friction means less use
Starlight Audio Recording
- Record with a USB-style recorder - no setup
- Teach naturally without self-consciousness
- Students remain anonymous
- Small files, quick upload
- Focus on teaching quality only
- Low friction = regular use
The Audio-First Advantage
Why lower friction leads to better professional development
Record More Often
When recording is easy, you do it regularly. Regular practice leads to faster improvement.
Teach Authentically
No camera means no performance anxiety. Capture your real teaching, not a staged version.
Complete Privacy
No visual record means no concerns about student identification or data protection issues.
Focus on Pedagogy
Audio analysis focuses on what you say and how you interact - the heart of effective teaching.
No Equipment Costs
A small USB-style recorder is all you need. No cameras, tripods, or special software to purchase.
Faster Feedback
Smaller audio files upload quickly, meaning you get your feedback faster.

Research on Lesson Recording
What the evidence says about audio vs video observation
Applying direct observation to audio recordings would produce quantitative scores and provide valuable feedback to teachers about their instruction.— Didion et al., Assessment for Effective Intervention (2023)
These results corroborate existing evidence that scalable and low-cost automated feedback can improve instruction and learning in online educational contexts.— Demszky and Liu, ACM Learning at Scale (2023)
The Bottom Line
Video adds complexity without adding value for most teaching feedback purposes. Starlight's audio-first approach captures what matters while removing the barriers that prevent teachers from engaging in regular self-reflection.
