This article seeks to provide researchers and practitioners in laboratory education, particularly those involved in the curriculum design and implementation of teaching laboratories at university level, with a conceptual framework and a working model for an integrated assessment of learning domains, by attending to a more holistic approach to…

Our goal in this article is to provide research-based strategies for embedding Nature of Science (NOS) into science instruction at the elementary level. We thus intend to aid researchers, professional developers, and teachers in noting that not only is it important and possible to teach NOS at the elementary levels, but also that elementary…

An introductory guide to deducing the mechanism of chemical reactions is presented. Following a typical workflow for probing reaction mechanism, the guide introduces a wide range of kinetic and mechanistic tools. In addition to serving as a broad introduction to mechanistic analysis for students and researchers, the guide has also been used by…

The paper opens by characterizing recent discourse about empirical educational research as the "new Babel"-critics, using different theoretical vocabularies and making different deep assumptions about the nature of social life, are failing to communicate with each other. After locating some of the critical positions on a left-right continuum, the…

Proposes a mathematical computer model for the behavior of liquids using the classical dynamic principles of Sir Isaac Newton and the molecular dynamics method invented by other scientists. Concludes that other applications will be successful using supercomputers to go beyond simple Newtonian physics. (CW)

What is science for a child? How do children learn about science and how to do science? Drawing on a vast array of work from neuroscience to classroom observation, "Taking Science to School" provides a comprehensive picture of what we know about teaching and learning science from kindergarten through eighth grade. By looking at a broad range of…

A "Xenograde system" is an imaginary science system. As an imaginary science, it contains a set of concepts and principles which mimic many of the concepts and principles found in physics and other physical sciences. Xenograde is a highly complex closed system which simulates the movement of satellites orbiting a nucleus and some small particles…

Discusses the mechanism and the change of pH during the reaction. Notes that a dramatic rise in pH occurs when the reaction nears completion. Evaluates theories by other authors. (MVL)

In this paper, in response to Ajay Sharma's paper titled "Portrait of a science teacher as a bricoleur: A case study from India" and associated reviews, I address the value of bridging two narrative styles for describing teacher development, discuss questions of over-essentializing an Indian school context, propose that teacher and…
