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…

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…

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…

In the fall of 2008, Stacy McCormack's students were caught up in the presidential election, and she began to wonder how she might harness this passion for politics in her high school physics classroom. At about the same time, a friend recommended the book "Physics for Future Presidents" (Muller 2008), which led her to develop a year…

We all have misconceptions about the world in which we live--how it works, how we interact with it, how it changes, and the reasons behind those changes. These misunderstandings are personal notions we create to make meaning of our surroundings. Often, these misunderstandings go unchallenged for a lifetime. This article addresses how these…

This article describes beginner habits and misconceptions related to design practices. Once teachers are aware of these habits and misconceptions, they can more easily recognize them and work to remedy them through instruction. Presented herein are eight practice habits. Each item begins with the practice, describes a related design habit or…

Misconceptions are not simply factual errors or a lack of understanding, but rather explanations that are constructed based on past experiences (Hewson and Hewson 1988). If students' misconceptions are not directly engaged in the learning process, they may persist--even when faced with instruction to the contrary (Bransford, Brown, and Cocking…

A floating bowling ball? No way! There is no better way to get students' attention and reinforce the need for conceptual understanding than with a discrepant event like this. Density is a central concept in chemistry and physical science from middle school to college. But often, particularly at the high school and college levels, we think students…

Too often, teachers scratch their heads and ask, "What were my students thinking?" then answer, "I don't want to know." But teachers should want to know, and students should question their own thinking, as well. Critical thinking involves not just problem solving, creativity, analysis, and synthesis but also self-awareness of learning and learning…

Students--and just about everyone else--tend to have a wide range of misconceptions about microbes. This article is aimed at changing how students view microbes by engaging them in two hands-on activities that are fun and creative and align with both the National Science Education Standards (NRC 1996) and the Essential Principles of Ocean Literacy…

Through integration of geology, biology, chemistry, and the history of science, the historic Krakatoa eruption offers a unique portal for student inquiry in the classroom. Students are inherently fascinated by natural disasters, and modern comparisons to the Krakatoa cataclysm are as close as the day's news. This article uses the historic Krakatoa…

Students should understand both the science and the engineering models of experimentation. Since students are often predisposed to using the engineering model, teachers must intentionally design activities that better reflect the nature of scientific experimentation. In this article, the authors recommend some guidelines that can be used when…

The law of conservation of mass can be counterintuitive for most students because they often think the mass of a substance is related to its physical state. As a result, students may hold a number of alternative conceptions related to this concept, including, for example, the believe that gas has no mass, that solids have greater mass than fluids,…
