<< Objectives >>The main intended achievement of the PRO-ME-ToM project is to provide a well-elaborated and tested developmental program for improving metacognitive and Theory-of-MinD (ToM ) skills' awareness, a crucial skill for a meaningful participation in the information society. Tests and description of in-class activities translated to five languages will be available for use to teachers form primary and secondary education in order to improve students' metacognitive thinking and ToM skills.<< Implementation >>There will be constructed assessment tools for evaluating metacognitively aware thinking of teachers and students from the primary and secondary education level. A 12-week training program will be developed to promote teacher’s metacognitive awareness and to build their capacity to teach metacognitive skills. The measurement tool and training program will be available in five languages (Greek, Romanian, Hungarian, Portuguese and English)<< Results >>During the PRO-ME-ToM project 30 primary and 30 secondary teachers from each participating country will be trained about how to use the developed metacognitive training program and measurement tools. Approximately 150 primary and 150 secondary school students from five countries will be empowered with the key competence of metacognitive thinking by participating in a developmental program. Tools for measuring and improving metacognition in school settings will be available in five languages.
