Science education needs to make students more scientifically literate and encourage larger numbers to take up science careers. Open schooling approaches can make science more authentic but tend to be adopted only as extra-curricular activities, in a minority of schools or are limited to gifted and talented students. CONNECT is an inclusive, sustainable model for enabling more secondary schools to adopt open schooling by embedding science-action projects in the core curriculum, using participatory science approaches with universities and enterprises. A science-action makes science more relevant to studentsOur age is profoundly shaped by science and technology innovations. Societies must become more scientifically literate to be able to make evidence-based decisions and sustain themselves in our highly competitive world. One solution that has been proposed for increasing students' aspirations in science is to open up school through partnerships and family involvement.To make open schooling inclusive and widespread in science education, we believe 3 questions need to be addressed: Q1. How can open schooling increase the value and priority of partnership activities and reduce the barriers to entry so more schools are willing and able to adopt them ? Q2. How can open schooling facilitate the interaction between all partners (science professionals, teachers, students and their families) to result in effective learning experiences linked to R&I? Q3. How can open schooling make science careers more inclusive by giving disadvantaged students more experience and insight into professional STEM jobs, supported by professionals and their families? CONNECT is an inclusive, sustainable model for enabling more secondary schools to adopt open schooling by embedding science-action gamification projects in the core curriculum, using fun approaches of participatory science with families, universities and enterprises to increase students’ interest and confidence with science in life.
