Experiment is understood as a core activity in science education as well as science in general. Despite many efforts to improve science education in the laboratory, a cookbook style of verification experiments often dominate school science. In this study, we conducted an open laboratory activity that provided students with an opportunity to think…

Bioscientific advances raise numerous new ethical dilemmas. Neuroscience research opens possibilities of tracing and even modifying human brain processes, such as decision-making, revenge, or pain control. Social media and science popularization challenge the boundaries between truth, fiction, and deliberate misinformation, calling for critical…

Teachers face challenges when building the concept of substance with students because tensions of meanings emerge from students' daily life and canonical ideas developed in classrooms. A powerful tool to address learning, pedagogical, and research challenges is the conceptual profile theory. According to this theory, people employ various ways of…

The importance of learning "chemical ways of thinking" is widely recognized. Various frameworks have been developed to address the essence of chemistry and chemical thinking. However, very few studies have focused on how chemical ways of thinking can be defined. To elaborate chemical ways of thinking, this paper draws on scientific…

The past decade has seen multiple debates and discussions over the appropriate framing of Nature of Science (NOS) for science education. These debates have stemmed from a diversity of philosophical views on what science fundamentally is. In post-secondary STEM education, the goals of a science education rest in having students socialize into…

The paper reports a study that used a Bernsteinian analysis in order to investigate the association between higher primary science curriculum and social equity in four contrasting socioeconomic contexts: British Columbia (Canada), Singapore, South Africa and Kenya. The official science curriculum of each jurisdiction was analysed in terms of…

The purpose of this study is twofold: first, to delve into professional development (PD) of science teachers' views about nature of science (NOS) throughout activities linking NOS aspects to science centers (SCs), and second, to reveal how a science teacher uses NOS aspects while teaching in SCs. An instrumental qualitative case study method with…

For many historians of science and science educators, the method of replicating historical scientific apparatus and experiments provides an avenue for science learning, promotes critical and independent thinking, and fosters a deeper understanding of the nature of scientific practice. This paper presents a research study where a group of high…

In order to increase scientific competence within the general population, it is important that teachers and educators have a realistic image of science and scientists, leaving aside superstitions and pseudoscientific claims that could be transmitted to their students. A starting point in this strategy is to make a good diagnosis of the future…

Understanding the nature of science (NOS) has emerged as a core curricular goal since at least the 1960s. While science education reforms around the world have shed light on various epistemic and social underpinnings of science, how science curriculum documents portray the nature of other related disciplines such as mathematics and engineering has…

In the USA context of the Next Generation Science Standards, elementary teachers face challenges in implementing engineering practices in their teaching due their lack of experience and training in engineering design. The paper reports about a multiple case study that examined one professional development approach to improve teachers'…

Growing interest in integrated science, technology, engineering, and mathematics (iSTEM) education has been promoted as one way to increase innovation capacity, support future employment, and enhance learning outcomes in K-12 education throughout the USA. Existing efforts to construct iSTEM curricula have largely focused on finding points of…

In comparison to teachers from Argentina and Uruguay, Brazilian teachers face greater difficulties in teaching biological evolution, due to religion. While Argentina has an official religion set in its constitution, Uruguay and Brazil are considered secular countries. Despite being a self-proclaimed secular country, Brazil tolerates and encourages…

The Covid-19 pandemic is the reason why humanity is paying more attention to the importance of regular and rigorous handwashing. Interestingly, in the nineteenth century, regular and rigorous handwashing was a key (and controversial) solution proposed by the Hungarian obstetrician Ignaz Philipp Semmelweis to cut drastically cases of puerperal…

The purpose of this paper is to investigate the effectiveness of pedagogical content knowledge (PCK)-based nature of science (NOS) teaching on pre-service science teachers' (PSTs) NOS views. The study is grounded by conceptual change and experiential learning theory. It is also framed by the teacher professional knowledge and skill (TPK&S) PCK…
