As the number of STEM opportunities and the need for a scientifically literate society increases, educators in STEM fields require tools that help support these needs. Chemistry is one STEM content area that would benefit from exploring educational technology that supports conceptual understanding. An action research study was conducted to…

In order to comprehend complex and abstract phenomena, students must partake in the process of learning by integrating complex and invisible components without ever physically encountering or manipulating such components. Prior knowledge and experiences will influence the way students assimilate and model new experiences and knowledge. If prior…

This paper provides some insights into the use of example-generating tasks in the design of a technology-rich learning environment to enhance students' mathematical thinking. The paper reports on an early stage of a design-based research project concerning the design of tasks and associated feedback utilising the affordances provided by a combined…

This study examined the effectiveness of three instructional and assessment strategies on conceptual understanding of the DNA molecule. Specifically, a model building task was utilized to determine if physical model construction, digital model construction with a touchscreen tablet computer, or paper worksheet activity effected conceptual…

The use of three-dimensional printing in chemistry education has expanded greatly in the past 10 years. The technique has been used to demonstrate a range of concepts including molecular structure, orbitals, and point groups; to produce chemical equipment such as cuvettes and columns; and even to print out mathematical shapes and functions. Here,…

Physical and life science disciplines emphasize how basic structural units influence function, yet it is challenging for students to understand structure-function relationships, particularly at molecular scales. Undergraduates in our biology capstone course struggled to connect mutations in a gene encoding a key protein in a cell development…

As computational models are becoming more widely used with the release of "A Framework for K-12 Science Education" (NRC 2012) and the "Next Generation Science Standards" ("NGSS"; NGSS Lead States 2013), these models are reshaping the way science is practiced in increasingly diverse classrooms. For students classified…

In this mixed method study, we analyse the effectiveness of two pedagogical approaches -- one model-based and another non-model-based -- for developing secondary students' understanding of the phenomenon of increase in Earth's average surface temperatures, a core dimension of global climate change (GCC). Building on past research on teaching and…

We present an accessible implementation of augmented reality projections for the depiction of complex structures and motifs, including atomic orbitals and elemental allotropes. The utilization of a free, cross-platform-compatible, online database of these structures provides the access route for closer examination, either via augmented reality or…

When teachers first wrap their heads around scientific modeling, it can be a bit tricky to distinguish scientific models from diagrams and three-dimensional models. If a fifth grader draws and labels a food web, it's a model. Right? Not necessarily. When creating a model, students should be representing a system inspired by an inquiry or…

A prescription favored in this article calls for the joint use of "learning maps" and "instructional maps." Why then the "Vs." in the title? Simply put, it is a rhetorical device. It calls attention to a key difference between the two. This article explicates the difference. It also informs how alone and in…

Although physics teachers often seek to help their students make sense of physics concepts, our field has yet to thoroughly explore how and why students engage in sensemaking. In this study we use the epistemic games framework to propose a model for students' sensemaking processes. Our analysis of a series of clinical interviews with introductory…

This is a position paper in the field of Engineering Education, which is at the very beginning in Europe. It relates challenges in the new field to the emerging technology of (Computer) Theorem Proving (TP). Experience shows, that "teaching" abstract models, for instance the wave equation in mechanical engineering and in electrical…

Remodeling of geography education has been an ongoing challenge recently. Constructivist pedagogy, employing tools of problem and model-based learning, offers new opportunities to meet these challenges. Geomodels, flumes and stream tables may ease the understanding of geographic processes through hand-on-experience for students. With a…

With the increasing attention and surge of empirical research in providing academic instruction for students with autism spectrum disorder (ASD) comes the need to provide teachers with research-supported strategies. Using one evidence-based strategy for teaching mathematics to students with high incidence disabilities, and another for teaching…
