The importance of introducing students to mechanistic reasoning (MR) early in their schooling is emphasised in research. The goal of this case study was to contribute with knowledge on how early primary students' (9-10 year-olds) MR in chemistry is expressed and developed in a classroom practice framed by model-based inquiry. The study focuses on…

This research aimed to use students' modeling processes as a means of scientific inquiry. Students constructed models to explain the interactions between felodipine R and S and protein. The approach encouraged active student participation in molecular interaction modeling and offered students a "model-based teaching" experience for…

Learning to plan modeling-based investigations (MBIs) presents significant challenges for pre-service elementary teachers. Although they understand disciplinary core ideas and modeling practices, they address both as competing learning goals and, as novices, they have not experienced how to structure MBIs for their future students. In the context…

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…

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…

Idealizations are omnipresent in science. However, to date, science education research has paid surprisingly little attention to the use of idealizations in fostering students' model competence and understanding of the nature of science (NOS). The starting point for the theoretical reflection in this paper is that insufficient consideration of…

When learning about scientific phenomena, students are expected to "mechanistically" explain how underlying interactions produce the observable phenomenon and "conceptually" connect the observed phenomenon to canonical scientific knowledge. This paper investigates how the integration of the complementary processes of designing…

The initial learning experience is a critical opportunity to support conceptual understanding of abstract STEM concepts. Although hands-on activities and physical three-dimensional models are beneficial, they are seldom utilized and are replaced increasingly by digital simulations and laboratory exercises presented on touchscreen tablet computers.…

The process of turning a doctoral student into an independent researcher is usually guided by a professor. In this work, the supervisor-supervisee relationship is represented by a scheme inspired by Michaelis-Menten kinetics, which has been used to determine the rate of enzyme-catalysed reactions. Here, the time evolution of the number of…

Chemistry is a systems science that deals with complex-dynamic systems and systems thinking is an essential aspect of chemical practices. Thus, a systems thinking approach is needed in chemistry education for meaningful learning of the subject matter. Despite this necessity, systems thinking has not received sufficient attention in chemistry…

The aim of this article is to propose a didactical approach to establish appropriate relations between different kinds of chemical knowledge and explanations at the macro and the submicro level. Incorrectly moving between these two levels is regarded as the cause of many misconceptions in school chemistry, and several theoretical frameworks have…

Virtual Reality (VR) has been widely adopted in educational research; however, its implementation in the classroom is still not as well known as in the research field. In other words, there is a gap between researchers and practitioners regarding the pedagogical issue. This study aimed to explore how VR could be applied in science classrooms using…

Understanding negative numbers can be challenging for many students, as these concepts may seem less tangible than counting objects, which are commonly represented by positive numbers. In addition, the multiplication of two negative numbers resulting in a positive might appear inconsistent and puzzling to young learners who are used to seeing the…

Peer Instruction gives practice in the abstract language of physics, addresses common misconceptions among students, and is more effective than traditional lecturing. However, it is not clear what makes Peer Instruction effective nor how we might improve the method. An emerging perspective is that what makes Peer Instruction effective is how it…

Many approaches to teaching Newman projections and conformational manipulation rely on lecturing using only two-dimensional representations. While molecular models are recognized as useful learning tools, students are often left to figure out how to use them during the initial learning process. The availability of basic online molecular models…
