Collan's learnings about the United States were refined in the Jyväskylä seminary teachers' union, where the need for children's exercise- and play areas was on the agenda in January 1915. The seminary teachers' union's protocol highlighted the need to renew the training school yards so they could be equipped with test equipment. Girls' and boys' schools would obviously get their own separate equipment and – as in America – play and exercise were also considered in the plans. Jump ropes, inclined climbing frames, jumping boards, basketball racks, push-up bars and a sled hill were planned for the girls' training school, and pole carousels, jumping boards, push-up bars, pole vaulting stands, a selection of axes for throwing , a 5 kg shot and a sled hill were planned for the boys' training school.
