Abstract
The paper analyzes the impact of interdisciplinary instruction on the perception, awareness, and knowledge about climate change of 102 Spanish pre-service primary teachers using a pre- and post-test design. Our findings demonstrate that pre- to post-test scores significantly increased in all the studied categorizations and that students’ academic background influences score improvement. Data also reveal that there is a positive and significant correlation between teaching capability perception and knowledge, suggesting that knowledge instruction is crucial for teachers’ confidence in climate change education. The study also confirms the opportunity to explore sustainable teacher education from an interdisciplinary perspective, carrying out congruent teaching from different approaches on a complex phenomenon to understand it in a holistic way.
