Acknowledging the central role of parents in children’s learning, SMASH aims to raise the educational standards of European youth in mathematics and science by cultivating underlying home cultures as springboards for learning. The project consortium has developed an intercultural parent-trainer training course and related resources for European teachers, school administrators, representatives of parent associations, and other professionals involved in training activities for parents. Through combined use of e-learning and physical meetings, the course prepares these professionals to implement in their communities culturally differentiated parent-training programs for supporting elementary and middle school children’s (ages 6-15) development in mathematics and science. Online multilingual resources support and promote the program’s activities and objectives by offering open access to the parent-trainer training course content, tools, and resources.
