This questionnaire evaluates a project called "C.U.O.R.E. (Cooperate Under the Objective of Recycling Energy)" for teachers. It asks teachers to rate the overall assessment of the project, the most significant aspects, how interesting they found the project activities, how the project helped make the school more environmentally friendly, whether it incentivized learning foreign languages, if it was an opportunity for teacher development, and how effectively the project activities were communicated. The questions aim to gather feedback on the impact and effectiveness of the inter-European cooperation project.
