To know or not to know: uncertainty is the answer. Synthesis of six different science exhibition contexts

by Helena Thuneberg and Hannu Salmi

This meta-article aims to explore the role of uncertainty in knowing in informal science learning contexts. Subjects (N=2591) were sixth-graders from four countries. In addition to the correct and incorrect questionnaire alternatives, there was a "don't know" option to choose if uncertain of the answer. The unique path-analysis finding showed that the role of motivation was uniformly positive on correct and negative on uncertainty of answers. In all contexts the number of correct answers increased, incorrect and uncertain answers decreased. Interestingly, although there was no more difference in knowledge pro boys after the intervention, the girls were still more uncertain.

Mathematical thinking skills, self-concept and learning outcomes of 12-year-olds visiting a Mathematics Science Centre Exhibition in Latvia and Sweden

by Hannu Salmi, Helena Thuneberg and Mari-Pauliina Vainikainen

Teaching mathematics in informal settings is a relatively new phenomenon, but it has gained more attention due to the recent changes in the society. The aim of the present quantitative study was to compare the learning outcomes of Latvian and Swedish 12-year-olds when they visited a science centre mathematics-art exhibition originally designed in Estonia. The results showed that in general, prior knowledge of the exhibition contents was the strongest predictor of post-test results in both countries but that mathematical thinking skills and self-concept had a small added value in explaining the post-test results. The results of the study give some of the first pieces of evidence of the effectiveness of out-of-school mathematics teaching in a science exhibition context, providing a good basis for further studies.
