This study aimed to evaluate the effect of a climate change awareness education program on knowledge, attitudes, and behaviors among secondary school students. The study was conducted as a cluster randomized controlled trial in a public secondary school in Istanbul, Türkiye.
This completed cluster randomized controlled trial evaluated the effect of a climate change awareness education program on knowledge, attitudes, and behaviors among seventh-grade secondary school students. The study was conducted in a public secondary school in Istanbul, Türkiye. Two classrooms were randomly assigned to the intervention and control groups. The intervention group received a structured, multi-component education program including classroom-based educational sessions, visual reminder posters, interactive quizzes, and eco-friendly reinforcement materials. The control group continued routine education during the data collection period. Outcomes were assessed at baseline and two weeks after completion of the intervention. After post-test measurements, the education program was also provided to the control group.

| Measure | Description | Time Frame |
|---|---|---|
| Change in Climate Change Awareness Score | Students' climate change awareness was assessed using the Climate Change Awareness Scale for Secondary School Students. The scale consists of 16 items and two subdimensions: cognitive awareness and behavioral awareness. Items are scored on a 5-point Likert scale. Total scores range from 16 to 80, with higher scores indicating higher climate change awareness. | Baseline and two weeks after completion of the intervention |
