At Algyő one of the Hungarian case studies was presented in details. The participants could attend three environmental education lessons at the Algyő Primary School. Each lesson was conducted partly by teacher students, and an action research questionnaire was administered by all the pupils, teachers, and students at the end of the activities. These questionnaires and other types of feedback (discussions, documents) are used for reflection and as a basis for future development both for teacher students and the school.
