Science|Environment|Health (S|E|H) is a new science pedagogy that aims at promoting the mutual benefit between the three educational fields of science education, environmental education, and health education. Holism and its conceptualisation has become an important topic in recent S|E|H work. In this paper, featuring the invited symposium of the ESERA special interest group 4 at the ESERA conference 2021, we suggest the concept of Two-Eyed Seeing as a basis for the definition of scientific holism in S|E|H. Two-Eyed Seeing as a metaphor was introduced by science education researchers working with Canadian aborigines. Based on Sellars’s concept of stereoscopic view, we conceptualize Two-Eyed Seeing in S|E|H through an ontological framework. We define scientific holism as the “eye switch” from the scientific image to students’ life-world image, a transition that we consider as equally important as the - more common - reductionist “eye switch” from students’ life-worlds back to the scientific image. Two-Eyed Seeing may then be understood as a continuous circulation of repeated “eye switches” between life-world image and scientific image. We illustrate this approach by three symposium contributions - communicating the meta-organism in school, scientific holism against eco- and health depression, and a holistic visual tool to approach S|E|H competences – and we discuss consequences for teaching and research in science education. We point out that, in a new S|E|H pedagogy and beyond, Two-Eyed Seeing may be a helpful extension to the well-established socio-scientific issues approach.

The magnetostrictive effect is an important topic for scientific research as well as for technological applications. Since magnetostriction constitutes an important property of emerging smart materials, experimental investigations as well as theoretical discussions of the magnetostrictive effect are of great educational value. Quantitative measurements of the magnetostrictive effect are usually technically sophisticated or not related to real applications or everyday materials. The objective of this article is to describe a simple and low-cost experiment for the qualitative and quantitative investigation of magnetostrictive characteristics employing magnetostrictive laser deflection and optical amplification. Measurements are performed for precut magnetostrictive materials found in electronic article surveillance tags. Comparative theoretical calculations for magnetostrictive cantilever beams prove the quality of the experimental approach. The described method for magnetostriction measurements has been developed as a part of the Scientific Outreach Project within the Collaborative Research Centre (CRC) 1261 “Magnetoelectric Sensors.”

Science|Environment|Health (S|E|H) is a new science pedagogy that aims at promoting the mutual benefit between the three educational fields of science education, environmental education, and health education. Holism and its conceptualisation has become an important topic in recent S|E|H work. In this paper, featuring the invited symposium of the ESERA special interest group 4 at the ESERA conference 2021, we suggest the concept of Two-Eyed Seeing as a basis for the definition of scientific holism in S|E|H. Two-Eyed Seeing as a metaphor was introduced by science education researchers working with Canadian aborigines. Based on Sellars's concept of stereoscopic view, we conceptualize Two-Eyed Seeing in S|E|H through an ontological framework. We define scientific holism as the "eye switch" from the scientific image to students' life-world image, a transition that we consider as equally important as the -more common -reductionist "eye switch" from students' lifeworlds back to the scientific image. Two-Eyed Seeing may then be understood as a continuous circulation of repeated "eye switches" between life-world image and scientific image. We illustrate this approach by three symposium contributions -communicating the meta-organism in school, scientific holism against eco-and health depression, and a holistic visual tool to approach S|E|H competencesand we discuss consequences for teaching and research in science education.

A major challenge in modern society is the need to increase awareness and excitement with regard to science, technology, engineering and mathematics (STEM) and related careers directly or among peers and parents in order to attract future generations of scientists and engineers. The numbers of students aiming for an engineering degree are low compared to the options available and the workforce needed. This may, in part, be due to a traditional lack of instruction in this area in secondary school curricula. In this regard, STEM outreach programs can complement formal learning settings and help to promote engineering as well as science to school students. In a long-term outreach collaboration with scientists and engineers, we developed an outreach program in the field of magnetoelectric sensing that includes an out-of-school project day and various accompanying teaching materials. In this article, we motivate the relevance of the topic for educational outreach, share the rationales, objectives and aims, models and implementation strategies of our program and provide practical advice for those interested in outreach in the field of magnetoelectric sensing.
