The ability to develop and use models to explain phenomena is a key component of the "Next Generation Science Standards", and without examples of what modeling instruction looks like in the reality of classrooms, it will be difficult for us as a field to understand how to move forward in designing curricula that foreground the practice…

This article describes practical lessons and experiences acquired as part of a journey in teaching a blind student at The University of Arizona to master the written and graphical language of first-semester organic chemistry and its associated concepts. These practical lessons include details on how to adapt an organic chemistry model set (with…

We examined the sophistication of middle school students' mechanistic explanations of genetics phenomena and how they interact with a technology-based explanation tool as they articulate and organize their ideas about the phenomena. We coordinated curriculum and assessment design frameworks to develop a middle school curriculum unit that engages…

Recently, there have been many calls for an increase in instruction on the nature of science (NOS) in schools (i.e. NRC, 1996; NGSS Lead States, 2013). These calls recognize the importance of this topic at all levels of science education, but there is little guidance in terms of how to address it effectively in curricula. Similarly, there have…

For many in the school science classroom, the term "microbiology" has become synonymous with "bacteriology". By overlooking other microbes, teachers may miss out on powerful practical tools. This article describes the development of an activity that uses algae and yeast to demonstrate gas cycling, and presents full instructions…

"A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas" emphasizes that the practice of science is inherently a model-building activity focused on constructing explanations using evidence and reasoning (NRC 2012). Because building and refining is an iterative process, middle school students may view this practice…

Earth Systems Science (ESS) is emerging rapidly as a discipline and is being used to replace the older earth science education that has been taught as unrelated disciplines--geology, meteorology, astronomy, and oceanography. ESS is complex and is based on the idea that the earth can be understood as a set of interacting natural and social systems.…

Based on the premise that thestructure of knowledge can aid in the construction of a curriculum because it can guide the organization of knowledge for learning, the author analyses the structure of some physical science concepts. (LC)

This cross-sectional study identifies key conceptual difficulties experienced by upper secondary school and pre-service chemistry teachers (N = 191) in the area of reaction rates. Students' ideas about reaction rates were elicited through a series of written tasks and individual interviews. In this paper, students' ideas related to reaction rate…

This article critiques the mechanistic grounding of traditional management education and proposes complexity science as a fitting explanatory model for an age of complexity, contributing timely and important educational content and instructional processes to management education. It highlights some of those contributions and reviews instructional…

Discusses the emergence of chaos as a major scientific subject and its place in historical, scientific, and technological context. Three sections provide (1) an overview of the scientific paradigm; (2) a review of the ideology of classical mechanics; and (3) examples of classical systems behaving in peculiar, nonintuitive manners. (MDH)

Scientific concepts and processes are best developed in the context of technological problem solving. However, even some of the best secondary science curricula are weak in technology education and visa versa. A goal of technology and science education is to integrate student learning of science and technology. The relationship between science and…
