Understanding and Engagement in Places of Science Experience: Science Museums,Science Centers,Zoos, and Aquariums

Science museums, science centers, zoos, and aquariums (MCZAs) constitute major settings of science learning with unique characteristics of informal science education. Emphasis will be given to the analysis of four specific characteristics of MCZAs that seem relevant for educational research and practice, namely, conditions of mixed motives and goals, staged popular science, and impact of physical layout, as well as the role of social exchange and participation. By doing so, we focus on the consequences of these characteristics for the learning processes and outcomes of visits of MCZAs. We show that outcomes encompass not only knowledge acquisition in a narrower sense but also changes in interest and beliefs.     

Development and reliability quantification of a novel test set-up for measuring footwear bending stiffness

Since footwear flexibility impacts functional design factors, numerous studies have investigated footwear bending stiffness. However, the various methods used to measure footwear bending stiffness have some limitations. Hence, the scope of this study was to develop and quantify the reliability of a novel test set-up for measuring footwear bending stiffness. A test set-up consisting of a hydraulic testing machine, a bending apparatus and a fixation unit was created that fulfilled the requirements specified in the initial phase of the study. The test set-up was evaluated by testing 15 different boots in three series of measurements. Bending stiffness of the boots ranged from 0.61 ± 0.03 to 2.38 ± 0.08 Nm/°. Two-way analysis of variance test yielded that the test set-up enabled the reliable measurement of footwear bending stiffness. Relative measurement uncertainty ranged from 1.3 to 6.1 %.     

An exploration of the feature-positive effect in adult humans

Experiment 1 compared the acquisition of a feature-positive and a feature-negative discrimination in humans. In the former, an outcome was signaled by two stimuli together, but not by one of these stimuli alone. In the latter, the outcome was signaled by one stimulus alone, but not by two stimuli together. Using a within-group design, the experiment revealed that the feature-positive discrimination was acquired more readily than the feature-negative discrimination. Experiment 2 tested an explanation for these results, based on the Rescorla-Wagner theory, by examining how novel discriminations, based on a combination of a feature-positive and a feature-negative discrimination, were solved. The results did not accord with predictions from the theory. Alternative explanations for the results are considered.
