In the face of current socio-environmental challenges, the linear logic of cause and effect that has been the pillar of modern Western science has proved insufficient to account for the differential and multi-levelled impacts that techno-scientific developments themselves have had and continue to make on the Planet. Questions of sustainability and…

We present a new secondary school teaching method of quantum uncertainties of two-state systems. Intending to be a material teachable in schools, only two-state systems described by real numbers can be considered. An elementary argumentation based on school statistics leads to the identification of the uncertainty of a physical quantity in such…

Sustaining a broad diversity of plants is key for a sustainable future. For instance, providing a variety of flowering plants in urban and agricultural landscapes mitigates the current decline of pollinators and biodiversity in general. Therefore, educating about the diversity of flowering plants has high current relevance for biology and…

The Framework for K-12 Science Education set an ambitious goal of broadening participation in science learning for all students. Meeting this vision will involve supporting teachers in making meaningful connections with the cultural and linguistic resources their students bring to school; in essence, developing pedagogies that frame these…

The law of conservation of momentum is a fundamental law of nature. It states that the momentum of an isolated system is conserved. In high school or introductory-level physics courses, for simplicity, teachers and textbooks always use collisions in one dimension as the examples to introduce the concept of conservation of momentum. To solve simple…

In this paper, I engage with arguments put forth by Blue Mahy in his article "A speculative-posthumanist examination of the 'science-ethics nexus' in Australian secondary schools." Mahy argues that by using relational posthumanist concepts as a diffractive lens, his critiques of Australian school science standards find the underlying…

In practical work focussing on conceptual development, students spend valuable in-class time on collecting data rather than making sense out of it. This provides a barrier to learning about the targeted concept. To address this problem, we developed an approach that we coin "collaborative data collection." Using a practical on the topic…

We present an experiment designed to study standing waves in a tube with one closed end. Two smartphones are used, one to emit a sound signal with a chosen frequency and another equipped with a microphone to detect the sound pressure level inside the tube. Due to the finite diameter of the tube, the standing wave node (or antinode) appears…

This article establishes a rational, feasible, and necessary conclusion to reform high school science content into an equitable experience for its wide diversity of students' self-identities. Research indicates that 85% of graduates would not normally have enrolled in any science course unless required. Their values are more aligned with their…

Old physics textbooks give us a great opportunity to learn about the history of science and rediscover different methods to teach physics to our students. There are many disused and forgotten experiments in them, but these can still be very useful to affirm and understand physics. This is the case of an instrument used in the 19th century to…

The excess of curriculum content is a well-known problem in high school biology. Some strategies to adjust the amount of content to the available classroom time have been proposed, but none has been widely accepted and applied. Furthermore, biology is frequently presented in high school not as an integrated science, but as a collection of…

This article focuses on the learning of the Lewis representation at the transition from high school to university, in France. Indeed, this notion is taught both in high school and in the first year of higher education but with different methods, which seems to hinder the learners. In this work, we observe 11th grade and higher education classes…

This article deals with the study of natural sciences in non-compulsory secondary education from the end of the nineteenth century until the educational reform in 1970. We begin with a critical review of the ways in which the secondary education curriculum and textbooks of this period conveyed established knowledge about natural sciences. We then…

Systems thinking is a powerful concept in biology which can help students understand how the diversity of contexts in the biology curriculum all have similar underlying characteristics. However, it is not currently a common feature in secondary education as it is not part of the National Curriculum of England. Research on systems thinking has…

The reduction of nitroarenes to anilines is a key transformation with real-life context, central to the preparation of many important fine chemicals. The importance of this transformation has led to its inclusion in not only university organic chemistry courses but also preuniversity, especially in Europe. A variety of reagent combinations have…
