Undergraduate organic chemistry students, as they study conformational analysis and stereochemistry, frequently have trouble manipulating three-dimensional structures on a two-dimensional page or screen. The inability to accurately convert three-dimensional bond-line representations into Fischer projections is one example of this. While some…

Digital timelines have been both transformational and supportive in enhancing the ways in which information is shared through text, images, interaction, and creativity to achieve course goals and objectives across numerous disciplines. In analyzing the experiences of teacher candidates (TCs) in their creation of a variety of resources to address…

In genetics education, symbols are used for alleles to visualize them and to explain probabilities of progeny and inheritance paradigms. In this study, we identified symbol systems used in genetics textbooks and the justifications provided for changes in the symbol systems. Moreover, we wanted to understand how students justify the use of…

Immersive learning is one of the leading trends in education. Immersive learning uses a simulated or artificial environment for a better learning experience. Design of intelligent learning platform and motivating content development is one key aspect of immersive learning. In this article, we propose an intelligent computer-assisted learning…

Visualizations and visual models are of substantial importance for science learning (Harrison and Treagust, 2000), and it seems impossible to study chemistry without visualizations. More specifically, the combination of visualizations with text is especially beneficial for learning when dual coding is fostered (Mayer, 2014). However, at the same…

Developing pre-service science teachers' epistemic insight remains a challenge, despite decades of research in related bodies of work such as the nature of science (NOS) in science education. While there may be numerous aspects to this problem, one critical element is that the NOS is a meta-concept that demands higher-order cognitive skills. One…

Visual representations are essential for communication and meaning-making in chemistry, and thus the representational practices play a vital role in the teaching and learning of chemistry. One powerful contemporary model of classroom learning, the variation theory of learning, posits that the way an object of learning gets handled is another vital…

Graphics presented alongside expository science texts can have a number of positive effects for instruction, including facilitating engagement, arousing interest, and improving understanding. However, because students harbor expectations about which contexts are likely to support better understanding, the mere presence of graphics also has the…

Research has shown that students have tremendous difficulties developing a qualitative understanding of wave optics, at all educational levels. In this study, we investigate how three different approaches to visualizing light waves affect students' understanding of wave optics. In the first, the conventional, approach light waves are represented…

This study investigated the mental representations of metallic bonding and the malleability of metals held by three male students aged 14-15 (Year 10) who were attending a Hong Kong school. One student was selected by their chemistry teacher as representing each of the highest, the medium, and the lowest level of attainment in chemistry in a…

Visual representations, including photographs, sketches and schematic diagrams, are a valuable yet often neglected aspect of textbooks. Visual means of communication are particularly helpful in introducing abstract concepts in science. For effective communication, visuals and text need to be appropriately integrated within the textbook. This study…

Undergraduate biology education provides students with a number of learning challenges. Subject areas that are particularly difficult to understand include protein conformational change and stability, diffusion and random molecular motion, and molecular crowding. In this study, we examined the relative effectiveness of three-dimensional…

Bodily manipulations, such as juggling, suggest a well-synchronized physical interaction as if the person were a physics expert. The juggler uses "knowledge" that is rooted in bodily experience, to interact with the environment. Such enacted bodily knowledge is powerful, efficient, predictive, and relates to sensory perception of the dynamics of…

Research has shown that technology-enhanced visualizations can improve inquiry learning in science when they are designed to support knowledge integration. Visualizations play an especially important role in supporting science learning at elementary and middle school levels because they can make unseen and complex processes visible. We identify 4…

This article describes how an interdisciplinary science class uses visuals in ways that can be adapted across disciplines and academic levels. The key to the use of visuals is that they are integral to the learning of the students, whether we begin with visuals to improve writing and thinking or use written texts as the basis for visual…
