Study Overview

The Invisible Burden: Teacher Beliefs and EdTech Adoption in Singapore Primary Schools — a qualitative study using conversational AI interviews to explore how teachers experience EdTech as a work-burden or work-saver.


Findings serve ICT Key Personnels (KPs) in developing strategies for meaningful EdTech-infused lesson delivery.

Data Collection

  • Platform: Edcafe chatbot (SAM3) — async text & voice
  • Participants: 61 teachers, Singapore primary schools
  • Period: 27 March – 3 April 2026
  • Duration: 20–25 min per session
  • Sampling: Pseudonymous; two pairs disambiguated (Joyce ×2, Sam ×2)

Scoring & Reliability

  • 12 spectra scored 1–6 by analyst, post-interview
  • Tone of voice coded independently (P/U/N per dimension)
  • Two-pass review: initial scoring → delta check against full corpus
  • 53 changes applied: 25 human-confirmed, 14 delta-triggered, S11/S12 recalibration
  • Cohen (1988) thresholds used for correlation strength

Cohen (1988) R² Thresholds — N=61

  • Very Strong — R² ≥ 0.49
  • Strong — R² 0.25–0.49
  • Moderate — R² 0.09–0.25
  • Weak — R² 0.01–0.09
  • Negligible — R² <0.01

Pearson r visualised; Spearman ρ more defensible for ordinal scales in formal reporting.

Tone coded independently of content — captures emotional register, not what is being reported. S1 excluded (factual; no affective dimension). Positive tone (n=25) tracks strongly with higher S2, S4, S11 scores. Negative tone (n=9) mean S4=2.33 vs Positive mean S4=4.16.

Dimension P % U % N % Note
S2 Work Burden28%56%16%Neutral dominant; burden rarely expresses as positive emotion
S3 Facilitating Cond.30%39%31%Highest N% of any dimension — facilities friction is felt acutely
S4 Volition49%41%10%Highest P% of non-overall dimensions — conviction is energising
S5 Resilience28%56%16%Mirrors S2; resilience talk is rarely positive in affect
S6 Psych Safety33%49%18%Moderate N; isolation is felt but not always named
S7 TechConf26%57%16%Mostly neutral; troubleshooting discussed matter-of-factly
S8 Collegiality33%54%13%Mostly neutral; sharing culture described, not celebrated
S9 Pedagogy48%44%8%Second-highest P% — pedagogy talk is where joy lives
S10 Blended33%51%16%Moderate; blending discussed pragmatically
S11 Std Impact46%43%11%Strong P%; teachers feel good about outcomes when they occur
S12 Std Ready18%64%18%Highest U% — readiness discussed clinically, not emotionally

Key finding: S10 (Blended Efficacy) is the single strongest predictor of S11 (Perceived Student Impact): r=0.733, R²=0.537. S9×S10 (r=0.75) shows pedagogy and practice are inseparable. S5×S6 (Resilience × Psychological Safety) at r=0.885 — school culture is the hidden variable behind both. S4 Volition/Agency is the bridge variable linking dispositional and practice clusters.

Correlation Network Summary
Two structural clusters emerge from the 45 pairwise correlations

Cluster A — Dispositional

Internal attitudes and interpersonal dynamics

Cluster B — Practice

Observable teaching behaviours and outcomes

Bridge Variable: S4 Volition/Agency

S4 correlates strongly with both clusters: with S5 Resilience (r=0.769), S7 Troubleshooting (r=0.769), S8 Collegiality (r=0.751) and with S9 Pedagogy (r=0.696), S10 Blended Efficacy (r=0.674). This means personal pedagogical conviction is the fulcrum. Dispositional support (safety, collegiality) enables agency; agency enables blended practice; blended practice produces impact.
