Enzymes are nature's catalysts, mediating chemical processes in living systems. The study of enzyme function and mechanism includes defining the maximum catalytic rate and affinity for substrate/s (among other factors), referred to as enzyme kinetics. Enzyme kinetics is a staple of biochemistry curricula and other disciplines, from molecular and…

Socially engaged engineering provides for student learning of the design, analysis, and practices of engineering as well as the ways that engineering is situated in sociocultural contexts. This paper provides a conceptual framework regarding socially engaged engineering for K-8 educators, researchers, and curriculum designers. The framework…

The addition of the arts to STEM education, now known as STEAM, adds a new dimension to problem-solving within those fields, offering students tools such as imagination and resourcefulness to incorporate into their designs. However, the shift from STEM to STEAM has changed what it means for students to learn within and across these disciplines.…

STEAM education can be described in two ways. One model emphasizes the arts and is not as concerned about the accuracy of the STEM fields. In the second model, STEM content is the prevailing force with a focus on accuracy, and the arts are used in limited and secondary resources for the teaching of the content. However, in order to promote…

"Approaches and Strategies in Next Generation Science Learning" examines the challenges involved in the development of modern curriculum models, teaching strategies, and assessments in science education in order to prepare future students in the 21st century economies. This comprehensive collection of research brings together science educators,…

We extend a unified and easy-to-use approach to measurement error and missing data. In our companion article, Blackwell, Honaker, and King give an intuitive overview of the new technique, along with practical suggestions and empirical applications. Here, we offer more precise technical details, more sophisticated measurement error model…

This book meets a demand in the science education community for a comprehensive and introductory measurement book in science education. It describes measurement instruments reported in refereed science education research journals, and introduces the Rasch modeling approach to developing measurement instruments in common science assessment domains,…

This article explores the practical relevance of pragmatism as a research paradigm through the example of a piece of pragmatic research that not only used both quantitative and qualitative research methods but also exploited the inherent duality of the data analyzed. Thus, the article aims to make the case that pragmatism as a research paradigm…

In this article, the author challenges the validity and usefulness of the concept of "paradigm," as this term has been used in the social sciences generally, and specifically in the debates over research methods. He emphasizes that in criticizing what he sees as the misuse of the paradigm concept, he is not arguing for dismissing or ignoring…

This article examines several methodological issues associated with combining qualitative and quantitative methods by comparing the increasing interest in this topic with the earlier renewal of interest in qualitative research during the 1980s. The first section argues for the value of Kuhn's concept of paradigm shifts as a tool for examining…

The article studies the differences in knowledge production between academic researchers. In this perspective, it attempts at first to answer the following question: what factors explain differences in knowledge production between Canadian researchers in natural sciences and engineering? After a presentation of some of the empirical evidence…

A functional paradigm was used as a means of interpreting why teachers and classrooms function as they do. An assessment of the nature and sources of the functional paradigms of high school biology teachers was the major consideration of this study. A population of 28 experienced high school biology teachers recognized for exemplary teaching…

Presents a theoretical framework for and a detaled description of a model for teaching scientific analogies. The framework focuses on the definition of an analogy, analogical learning, variables related to analogical learning, evaluating outcomes of analogical limiting, and limitations of using analogies in teaching. (JN)

Investigates the effect of modeling analogy on learning of the concepts of electricity in grade 6, 8, and 10. Describes 2 analogies (train analogy and thermal analogy) with diagrams and examples. Discusses the accessibility, transferability, and difficulty of each analogy. Reports treatment effect and some further implications. (YP)

Presents a model of expert reasoning practices that focuses on constructive modeling, a tacit dimension of the thinking practices of expert physicists. Draws on historical cases and protocol accounts of expert reasoning in scientific problem solving and argues that having expertise in physics requires facility with the practice of constructive…
