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…

The inductive effect is one of the very important concepts of electronic effects in organic chemistry. In traditional teaching methods, only the origin, transmission mode, and decay of the inductive effect are introduced briefly, which is not conducive to students' complete understanding of the inductive effect. This work developed a new method to…

In recent years, pedagogical advancements have allowed the adoption of more engaging forms of course assignments to help students better understand and communicate chemistry. In this context, informational graphics, known as infographics, emerge as an effective teaching aid in educational settings and in disseminating scientific content to the…

pH determination and acid-base titrations are essential experiments performed by high school and university undergraduate students alike throughout their chemistry education. While these experiments often rely on conventional pH meters for quantification and pH test strips or indicators for qualitative assessments, we demonstrated herein that a…

The effectiveness of a formal charge method to draw Lewis structures that was developed by Curnow was studied quantitatively by direct comparison of two groups of students: one of which was taught the new formal charge method and another that was taught a traditional method. Students' marks on a common assessment were found to improve by…

Investigating and understanding novel antibacterial agents is a necessary task as there is a constant increase in the number of multidrug-resistant bacterial species. The use of nanotechnology to combat drug-resistant bacteria is an important research area. The laboratory experiment described herein demonstrates that changes in the nanostructure…
