Creativity is a broad and complex construct, difficult to define and to quantify, assumed to introduce new impulses into science education (STEM), and leading to better acceptance of science by adolescents. Therefore, increasing efforts are being undertaken to integrate traditional creativity (Arts), in modifying STEM to STEAM. Consequently, a…

Efficient waste management is a major prerequisite for reaching sustainability as every one of us produces waste. Thus, educational interventions need to offer promising assistance to reduce individual waste as much as possible to promote environmentally friendly behavior beyond stereotypical notions about waste disposal. Those who know about all…

In line with previous studies, where outdoor nature experience was shown to support adolescents' environmental knowledge, our study monitored the influence of a hands-on environmental programme within a National Park on cognitive knowledge achievement. A sample of 4th and 5th graders (n = 289) completed a week-long outreach conservation programme…

One aim of environmental education is fostering sustainable environmental action. Some environmental behaviour models suggest that this can be accomplished in part by improving people's knowledge. Recent studies have identified a distinct, psychometrically supported environmental knowledge structure consisting of system, action-related and…

We applied cognitive load theory in an heuristic out-of-school science lesson. The lesson comprises experiments concerning major attributes of NaCl and was designed for 5th to 8th grade students. Our interest focused on whether cognitive load theory provides sufficient guidelines for instructional design in the field of heuristic science…
