Research purposes and design: This study aimed to compare the effects of different explicit approaches used in modeling-based instruction on students' understanding of scientific models and modeling (USMM). In Study 1, a self-study approach was compared to a preliminary explicit approach. In Study 2, preliminary explicit approach and embedded…

Preservice elementary teachers enter their science methods courses with a range of prior experience with science practice. Those prior experiences likely inform much of their science pedagogy and goals. In this study, the authors examine how a cohort of preservice elementary teachers engaged in science practice as they learned content in a physics…

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…

Researchers of science education, historians, and philosophers of science agree that the teaching of nature of science (NOS) is important to be integrated into K-12 classes. Our previous research showed that NOS is not embedded into science teaching in Greece. To study the possibility of its integration, a PD-program for in-service science…

This mixed-methods study examines how pre-service teachers select instructional videos on YouTube for physics teaching. The study focuses on the role of surface features that YouTube provides (e.g., likes, views, thumbnails) and the comments underneath the videos in the decision-making process using videos on quantum physics topics as an example.…

Representation plays an important role in helping students understand chemistry learning. This is due to the many chemical concepts that require visualization. Representation is something that still needs to be studied. So this study aims to see the development of representation research in chemistry education. The articles used in this study are…

In this article we analyze the classic Hodgkin and Keynes 1955 paper describing investigations of the independence principle, with the expectation that there is much students and educators can learn from such exercises, most notably how the authors applied their diverse skill set to tackling the numerous obstacles that the study presented. The…

This study explores science teachers' questions encouraging students to see and speak about natural phenomena in novel ways. In particular, the teachers' challenging questions that may be instrumental in persuading students to see and talk about everyday events differently were qualitatively examined. The participants were 22 science teachers.…

Vector fields are a highly abstract physical concept that is often taught using visualizations. Although vector representations are particularly suitable for visualizing quantitative data, they are often confusing, especially when describing real fields such as magnetic and electric fields, as the vector arrows can overlap. The present study…

During the pandemic and lockdown situations of the last few years, we transitioned to online, physical, and hybrid education approaches at various times. We had difficulty teaching multiple calculus and analytical geometry units online. In light of the current situation, a graphical user interface (GUI) teaching tool has been developed to teach…

By adapting a well-established expository style practical on the topic of chemoselectivity, we present our successful approach to introducing elements of guided inquiry and decision-making to novice undergraduate chemists. Using nitroacetophenone as the polyfunctional substrate, students investigate the effect of using two different classes of…

In England, there has been a teacher recruitment and retention crisis for many years. In such a crisis, it is important that initial teacher education (ITE) providers are able to identify, recruit and educate 'high quality' applicants to join the teaching profession. In this study, we focused on two case studies of beginning teachers who were…

This study examines pre-service primary school teachers' (PSTs') possible selves in relation to science teaching and the ways in which these possible selves change over time. This longitudinal study adds to the body of knowledge by examining PSTs' possible selves at various time points throughout their teacher preparation: three PSTs, selected…

Science is the study of the world around us, and a scientist's job is to ask questions about the world and then experiment to find the answers. There is not a more natural scientist than the Elementary child, whose reasoning mind is eager to ask questions, investigate, and discuss and compare findings with their peers. In this article, the authors…

Background: In the context of recent research in science education and continued struggles to understand how best to support science teachers, epistemological frames, made up of sets of epistemological resources teachers activate, have emerged as an important focus of research. However, at the time of this writing no research was available to…
