EFApp is the Executive Functions Progressive Web App for coaches and teachers, with propositions, explanations and interventions, to engage in talking with kids in every school, about their executive skills. Having that conversation let`s you easily discover their request for help, and find what goes well and what could be improved. Executive functions are 11 skills you need to succeed in life: at school, at work, in relation to others. These so-called modern skills we think have always been important to us. Making a child understand what could be improved and making him or her co-owner of the problem and things to be learned is a `21st Century Skill` of the teacher. We want to empower you. Talk with them, not about them.
