Traditionally, assessing and grading students in science has been an exercise centered around points and percentages (Feldman, Kropf, and Alibrandi 1989; Prøitz 2013). However, with the introduction of the Next Generation Science Standards (NGSS) and the need to revisit grading practices stemming from the COVID-19 pandemic, an increasing number of…

Over the past year, educators have developed curricula teaching about the COVID-19 pandemic (Reed 2020; Royce 2020; Sadler et al. 2020). Many of these curricula feature computer simulations of epidemic dynamics (Kelter 2020; Sadler et al. 2020). Because an epidemic pattern is an emergent property of interacting human behaviors, it is crucial for…

In March of 2020, the world of education was upended. Teachers and students across the globe abruptly left their classrooms. Once taught in abstraction, science concepts became national headlines, no longer relegated to textbooks. Misinformation began spreading faster than any virus, and for many science teachers, addressing scientific untruths…

There are three aspects of science: (1) scientific knowledge: what we know about the natural world, which would include crosscutting concepts; (2) scientific practices: skills and knowledge necessary for building scientific knowledge; and (3) nature of science (NOS): how science works (Bell et al. 2003). Most science instruction emphasizes the…

The United States is currently experiencing its most severe measles outbreak in decades, driven in part by parents' belief that vaccines cause autism. That harmful misinformation is contrary to scientific evidence (DeStefano et al. 2013). The CEO of the American Association for the Advancement of Science, the world's largest multidisciplinary…

Increasingly, science teachers are expected to devote instruction to technology and engineering, as encouraged by the Next Generation Science Standards (NGSS Lead States 2013). Just as scientific literacy requires understanding the nature of science (NOS), technological literacy must include understanding the philosophy and nature of technology…

Helping students understand the Nature of Science (NOS) is a long-standing goal of science education. One method is to provide students examples of science history in the form of short stories. This article modifies that approach, using historical case studies to address both the history of science and the history of technology, as well as the…

Along-standing energy lab involves dropping bouncy balls and measuring their rebound heights on successive bounces. The lab demonstrates a situation in which the mechanical energy of a system is not conserved. Although students enjoyed the lab, the author wanted to deepen their thinking about energy, including the connections to motion, with a new…

Although the "Next Generation Science Standards" (NGSS Lead States 2013) were released over two years ago, misconceptions about what they are--and are not--persist. The "NGSS" provide for consistent science education opportunities for all students--regardless of demographics--with a level of rigor expected in every location and…

The vision of Next Generation Science Standards (NGSS) "requires a dramatic departure from approaches to teaching and learning science occurring today in most science classrooms K-12" (Reiser 2013, p. 2). In this article the authors emphasize the importance of examining student misconceptions and correcting them with sense-making…

One way to probe students' misconceptions about science during instruction is by using formative assessments. Described as assessments "for" learning rather than assessments "of" learning (Black and Wiliam 1998), they provide teachers with information about student understanding during instruction. Examples of formative…

Materials science--the science of stuff--has made our lives better by making it possible for manufacturers to supply us with products. Students have misconceptions about materials use. Many may think using bottled water, for example, is harmless because they recycle the plastic empties, but they fail to consider the resources and energy used to…

Misconceptions about climate change are common, which suggests a need to effectively address the subject in the classroom. This article describes a project-based science activity in which students report on the physical basis, adaptations, and mitigation of this global problem, adapting the framework of the United Nations' Intergovernmental Panel…

To promote teaching science through inquiry, the author wanted to use his experience in the Galápagos to design a lesson that allows students to immerse themselves in the essential science and engineering practices identified in the "Next Generation Science Standards," as they ask questions; analyze and interpret data; engage in argument…

High school students often enter classrooms with misconceptions about density. While many students may have studied the concept in middle school, they lack the understanding on which to build more advanced concepts, such as the particulate nature of matter. This lack of understanding poses problems for students' learning about Pascal's principle…
