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

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

Learning with dinosaurs: a study on motivation, cognitive reasoning, and making observations

ABSTRACT Dinosaurs have been a very popular science topic since signs of their presence on earth were first discovered. They have represented so-called ‘edutainment’ for some people. Learning from informal sources and in- an out-of-school environment can be effective and motivating. In this study, 12-year-old pupils (N = 366) visited a dinosaur science centre exhibition in Finland. Pupils were tested with standardised tests of motivation as defined by self-determination theory, cognitive skills, and interest via pre-, post-, and delayed post-tests during a six-month period. Findings show that pupils learned from the science centre visit and enjoyed the experience. The factors explaining their post-test knowledge in addition to their previous knowledge were (1) general cognitive competence, (2) liking studying biology at the science centre, (3) participation in a dinosaur demonstration, and (4) gender. As there was no difference between boys and girls in general cognitive competences, the knowledge results of boys and girls equally related to their cognitive competence. Autonomy also influenced situational motivation both directly and indirectly, which in turn had a strong effect on liking studying in the exhibition. It also influenced the post-test knowledge indirectly. In the lowest school achievement group, participation in the dinosaur demonstration increased knowledge in the post-test.

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

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. Abstract

Hands-On Math and Art Exhibition Promoting Science Attitudes and Educational Plans

The current science, technology, engineering, art, math education (STEAM) approach emphasizes integration of abstract science and mathematical ideas for concrete solutions by art. The main aim was to find out how experience of learning mathematics differed between the contexts of school and an informal Math and Art Exhibition. The study participants () were 12-13 years old from Finland. Several valid questionnaires and tests were applied (e.g., SRQ-A, RAVEN) in pre- and postdesign showing a good reliability. The results based on General Linear Modeling and Structural Equation Path Modeling underline the motivational effects. The experience of the effectiveness of hands-on learning at school and at the exhibition was not consistent across the subgroups. The lowest achieving group appreciated the exhibition alternative for math learning compared to learning math at school. The boys considered the exhibition to be more useful than the girls as it fostered their science and technology attitudes. However, for the girls, the attractiveness of the exhibition, the experienced situation motivation, was much more strongly connected to the attitudes on science and technology and the worthiness of mathematics. Interestingly, the pupils experienced that even this short informal learning intervention affected their science and technology attitudes and educational plans.
