Contributions of Expert Analysis to a Model of In-Service Teacher Professional Development in Environmental Citizenship Education

An effective response to the socio-environmental crisis requires the education of critical citizens, capable of articulating local action with collective socio-political engagement. Teachers occupy a central position in educating for Environmental Citizenship (EC), yet in-service professional development models in this area remain scarce. Within a Design-Based Research framework, this article discusses the expert evaluation of a training prototype. 32 experts—comprising EC researchers, TPD researchers, and specialist teachers—responded to a qualitative questionnaire regarding the model’s design. Data underwent inductive content analysis, with categories emerging directly from the responses. While results strongly validate the prototype’s structure, crucial recommendations emerged for its improvement. Pedagogically, experts suggested focusing on structuring methodologies like Problem-Based Learning and Case Studies to avoid fragmentation. Conceptually, they highlighted the need to deepen critical theoretical foundations and incorporate explicit training in activism and communication skills, enriched by ethical considerations. These findings inform the redesign of a model whose implementation aims to reduce the gap between ecological awareness and transformative civic action, preparing teachers to foster genuine agency in their students.
