Some of the most important scientific studies are associated with either incredibly large dimensions (e.g., the universe) or extremely small proportions (e.g., the cell). While a teacher's curriculum may often switch from mega-expanses to minutia, they should question how easily students comprehend the change in sizes. This article addresses…

The "Next Generation Science Standards" (NGSS Lead States 20103) identify evidence-based argumentation as a key practice in science education. This argumentation comes in many forms, each providing a unique theoretical perspective and area of educational research. Argumentation can help model aspects of scientific culture and…

In this article, Renee Clary and James Wandersee describe the beginnings of "Classification," which lies at the very heart of science and depends upon pattern recognition. Clary and Wandersee approach patterns by first telling the story of the "Linnaean classification system," introduced by Carl Linnacus (1707-1778), who is…

The "Next Generation Science Standards" ("NGSS") emphasizes content and scientific practices, but what does this actually look like in a classroom? The "NGSS" integrates scientific and engineering practices with core ideas and crosscutting concepts, merging the three dimensions from "A Framework for K-12 Science…

Since 1996, science education has been guided by the National Science Education Standards (NRC 1996). But now there's a "new sheriff in town" as the "Common Core State Standards" and "A Framework for K-12 Science Education" together become the 21st century's torch bearer for curricula reform in science and…

The Next Generation Science Standards (NGSS Lead States 2013) were released almost two years ago. Work tied to the NGSS, their adoption, and implementation continues to move forward around the country. Stephen L. Pruitt, senior vice president, science, at Achieve, an independent, nonpartisan, nonprofit education reform organization that was a lead…

In a regional gathering called the Youth Water Summit, high school students present projects that respond to the driving question behind their science curriculum: "How can you address a significant water resource challenge in your community's watershed?" Students exhibit scientific posters, interactive presentations, films, art projects,…

In this guided inquiry, students investigate advantages and disadvantages of genetic engineering by integrating popular fiction into their study of bioethics. What are the effects of artificially created hybrid creatures on characters in "The Hunger Games" and in our society? What are the effects on and basic rights of the organisms…

There are many types of inquiry activities out there: Demonstrations, guided or scaffolded inquiry labs, open- or free-inquiry labs, and problem-based or project-based learning activities are all staples in science education. The importance of inquiry is highlighted in such documents as the National Science Education Standards (NRC 1996) and the…

Scientifically literate citizens need to understand how scientists evaluate competing explanations. Likewise, students must learn to critically evaluate the quality of scientific knowledge and weigh alternative explanations. Regrettably, high school graduates often are not critically evaluative about scientific topics. To help remedy that, this…

Teachers often ask: How can I engage my students in the study of "real" science? The answer can be found in the National Research Council's "A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas" (NRC 2012). This framework calls for a new approach to science education and is the basis for…

Modeling is one of the scientific practices featured in the "Next Generation Science Standards" ("NGSS") (Achieve Inc. 2013). This practice is central to the work of science because modeling activities can prompt new questions for investigation, which, in turn, can lead to evidence and information that can be incorporated into…

Along with the need to make their curriculum more comprehensive and reflective of the national and state standards, one school district also searched for ways to make students more passionate about learning science. As a result, they developed a new integrated science course that is centered around the environmental and Earth sciences with an…

A correlated science lesson is characterized as an integrated science lesson in that it may incorporate traditionally integrated activities and use math as a tool. However, a correlated math-science lesson also: (1) has the pertinent math and science objectives aligned with state standards; and (2) teaches parallel science and math ideas equally.…

Mitosis and meiosis are essential for the growth, development, and reproduction of organisms. Because these processes are essential to life, both are emphasized in biology texts, state standards, and the National Science Education Standards. In this article, the authors present their methodology for teaching mitosis by having students produce…
