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…

This work is an attempt to see how physics undergraduates view the basic ideas of general relativity when they are exposed to the topic in a standard introductory course. Since the subject is conceptually and technically difficult, we adopted a "case studies" approach, focusing in depth on about six students who had just finished a one semester…

At a time when scientific and technological competence is vital to the nation's future, the weak performance of U.S. students in science reflects the uneven quality of current science education. Although young children come to school with innate curiosity and intuitive ideas about the world around them, science classes rarely tap this potential.…

Researchers and practitioners alike express concerns about the conceptual difficulties associated with the concepts of momentum and kinetic energy currently taught in school physics. This article presents an in-depth analysis of the treatment given to them in 44 published textbooks written for UK secondary school certificate courses. This is set…

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…

This investigation was guided by the following research questions: (1) how do teachers' understandings of the nature of science influence classroom practice?; and (2) what factors facilitate or impede the influence of teachers' understandings on classroom practice? An in-depth, year long assessment of the classroom practices and goals of five…

Most physics problem-solving studies provide data that indicate problem representation is different between experts and novices. This paper presents "cognitive aids" guiding the process of elaboration of a problem representation through intermediate representations. Intermediate means that the representation is situated somewhere between…

Investigates the influence of five cognitive variables on high school students' performance on balancing chemical equations by inspection. Reports that reasoning, restructuring, and disembedding variables could be a single variable, and that working memory capacity does not influence overall performance. Results of hierarchical regression analysis…

Identifies an induced incorrect generalization as a generative cause for the formation of misconception. Analyzes students' protocol of an exploratory learning experiment about the laws of reflection of light. Suggests recommendations for textbook, teaching, and practical work. (Author/YP)

This paper provides a critical review essay of Ajay Sharma's "Portrait of a science teacher as a bricoleur: A case study from India." The main focus is two fold. First, arguments are presented to draw attention to how little advances in science teaching and science learning research have impacted teachers' practice and student…

Investigates the remediation of misconceptions through application of Gagne's hierarchical learning theory. Uses stoichiometry, food levels, and conservation of mechanical energy as the target concepts. Reports that there was no treatment effect in analysis of covariance using pretest scores as a covariant. (YP)

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…

The "Habitat" learning system was designed by TVOntario's Children's Programming department for junior-level students. It consists of 20 programs (each 15 minutes long), a teacher's guide, and a magazine for students. Three major objectives of the series were to (1) instruct children in scientific principles relating to habitats; (2)…
