This study investigates the role of learning dimensions in planning and trialing teaching-learning sequences (TLSs) on surface phenomena in liquids for high school students. Particularly, it aims to identify how different modeling approaches--macroscopic and mesoscopic--impact students' learning in terms of different dimensions of learning such as…

The French natural philosopher Henri Victor Regnault (1810-1878) was one of many researchers who contributed to the development of the thermometer in the 19th century. In this paper, we use an example from Regnault's work to explore how the history of thermometry can provide a context for teaching upper-secondary chemistry students about the…

This article systematically reviews the pedagogical approaches adopted in high school chemistry education with the aim of highlighting the most effective evidence-based instructional practices reported in the literature. For this, a meta-analysis of 35 pedagogical approaches is analyzed, and their effect sizes (Cohen's d) are compared in terms of…

Especially within the light of the current loss of biodiversity, we want our students to gain a better understanding of the issues at stake in order to take action and support plants and their pollinators. Many educational approaches focus on honeybees, disregarding the vast diversity in the context of pollination systems and the complex…

Modern, student-oriented teaching can be characterized by the promotion of autonomy and interest. In the school subject of biology, it is necessary to focus on different ecosystems from different aspects. One ecosystem that has hardly been considered in biology didactics so far is the UNESCO World Heritage Wadden Sea. Therefore, this study…

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…

Research in physics education has revealed that students often have incomplete and incoherent ways to use the concept of photon. Most researchers in science education recommend photons to be taken in a realistic sense as existing entities of quantum objects. Furthermore, in science education literature it is often claimed that realistic stance to…

This study examines the impact of the Scientific Creativity in Practice program on students' scientific creativity. This comprehensive teaching program aims to foster general creative skills, domain-specific competencies, and certain personality traits in science education. The program includes a variety of interventions and reflection tools that…

To make sense of our interconnected and algorithm driven world, students increasingly need proficiency with computational thinking (CT), systems thinking (ST), and computational modeling. One aspect of computational modeling that can support students with CT, ST, and modeling is testing and debugging. Testing and debugging enables students to…

Energy is one important concept in physics, but science education research has repeatedly shown that students struggle to develop a full understanding of energy. Especially challenging for students is the notion of potential energy. Overwhelmed by the sheer number of potential energy forms, students struggle to make connections between them.…

Titration is an important experimental skill that every chemistry educator and learner must master. Titration is often the method of choice in the science laboratory courses in secondary and postsecondary schools. During acid-base titration, chemistry learners are always told about salt formation. However, a practical visualization of the salt…

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…

About 30 years ago I taught a series of summer enrichment programs for high school physics teachers, using funding from the Howard Hughes Medical Institutes. I deliberately chose teachers from smaller cities and towns who were unlikely to have contact with other physics teachers. One of my more interesting teachers came from a rural area in a far…

A didactic sequence is proposed using an infrared puzzle and a didactic questionnaire for the teaching-learning of infrared spectroscopy at the upper secondary level. The didactic sequence that was designed was implemented in person in the subject of Chemistry IV at the high school level, corresponding to the sixth semester of the curriculum of…

In the context of the current COVID-19 pandemic, we deem of importance the identification of what content is privileged in secondary schools around health and disease. From our point of view, a relevant task is to accompany science teachers in their transit from teaching information to be evoked to teaching knowledge on that content that enables…
