Children's drawing served as the primary data collection method (with a high reliability coefficient, Cronbach's α = 0.90). An experimental group (with the influence of informal learning) and a control group (without an experimental influence) underwent pretests and posttests. The posttest scores show a significant between-group difference in the expected direction; the experimental group had higher scores on average when compared to the control group. Interestingly, understanding of forest ecosystems was worse in comparison to the understanding of meadow, soil, and water systems across groups; informal learning did not have an effect in this respect.
