Skilled and Technical Science Educators (STSEs) enter the teaching field with little to no practical training. This lack of experience produces educators who need professional learning opportunities that draw upon their past knowledge and provide them with a community in which they can learn. The support these educators require extends beyond…

It is 157 years since Mendel presented his results on hybridisation in peas to the Brünn Society for Natural Science. The discipline of genetics has dramatically changed since then, with technological advancements revealing multifactorial causation and trait variability. Whilst none of this complexity featured in the discovery of classical…

This study aims to examine the effect of conceptual understandings related to anion-cation, acid-base, ionic-covalent, metal-nonmetal, and number of protons-number of electrons concept pairs taught in the periodic table to 8th grade students with the 5E learning model supported by concept maps. The study was conducted among 100 (50 in the…

The aim of the study is to reveal physics teachers' views on constants in teaching physics subjects that include physical constants. The phenomenology approach, one of the qualitative research designs, was used in the study. The study group consists of a total of 10 physics teachers, 2 female and 8 male, working in five public high schools in two…

Conceptual approaches to contemporary physics topics pose many learning challenges. One factor influencing knowledge integration is a student's epistemological framing. Epistemic frames provide a context within which a particular situation is perceived, interpreted, and judged. The utility of an epistemic frame is context dependent, and the…

The Next Generation Science Standards (NGSS) put forth an aspiring call for science educators to enact instructional experiences that enable all students to participate in the real-world practices of science. To achieve this, teachers need to create classroom environments that will attract all students to science learning and support and sustain…

In "Teaching Toward Rightful Presence in Middle School STEM," Edna Tan and Angela Calabrese Barton introduce the rightful presence framework, a multifaceted approach to instruction that enables historically marginalized students to gain agency in their science, technology, engineering, and mathematics (STEM) learning. This necessary work…

Aim: This study aims to elevate the modelling skills of Grade 10 students in understanding the circulatory system, using model-based learning, to a level where they can achieve at least a 70% passing score on a relevant unit test. Method: The study involved 23 students and implemented a model-based learning approach. Research tools included a…

This paper examines how practicing teachers approach and evaluate students' critical thinking processes in science, using the implementation of an online, inquiry-based investigation in middle school classrooms as the context for teachers' observations. Feedback and ratings from three samples of science teachers were analysed to determine how they…

Calls to immerse students in the sensemaking practices of science recommend that students propose ideas and work together to construct explanations as well as drive the evaluation and decision-making around classroom knowledge-building. In other words, they should be participating with epistemic agency. Part of the teaching work of supporting…

Argumentation scaffolding can be used to enhance the formulation of logical arguments as well as the performance of such arguments. This study presents a web-based synchronized scientific argumentation environment integrated with prompt scaffolding to support simulation-based physics learning for elementary school students. To investigate the…

Augmented reality (AR) recently shows great potential to facilitate students' learning, especially their learning performance and motivation. However, few studies considered learners' emotional factors such as learning anxiety, which may influence the learning results. This study aims to explore how different experimental conditions (AR &…

One way of triggering students' interest in chemistry is making chemistry education more meaningful. Four characteristics of meaningful chemistry education (MCE) were identified in projects that involved a redesign of curriculum materials: daily life context, the need-to-know principle, students' input, and the macro--micro connection. Chemistry…

Chemistry and Chaos is a role-playing game that was developed to teach a wide variety of chemistry topics. The game uses the traditional role-playing framework to present material in an engaging and interactive format. The students take on the role of a particular type of chemist while the instructor guides them on an adventure to test their…

The rise of virtual and online education in recent years has led to the development and popularization of many online tools, notably three-dimensional (3D) models and augmented reality (AR), for visualizing various structures in chemical sciences. The majority of the developed tools focus on either small molecules or biological systems, as…
