The second project result is the creation of a web-based OER with screening instruments (development screening instruments) and early intervention exercises for children with developmental delay. They will be placed on a web-based open-source web-based OER for early interventions in children. Different types of screening instruments for different ages from birth-to-six will be created, adequate for the European region. The early intervention exercises for different developmental milestones will be created, they will be recorded and placed on the web-based OER.
