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,…

In this paper, I discuss different types of models in science education and applications of them in learning and teaching science, in particular physics. Based on the literature, I categorize models as conceptual and mental models according to their characteristics. In addition to these models, there is another model called "physics model" by the…

Science educators agree that an undergraduate research experience is critical for students who are considering graduate school or research careers. The process of researching a topic in the primary literature, designing experiments, implementing those experiments, and analyzing the results is essential in developing the analytical skills necessary…

Scientists often have to observe and study surfaces that are impossible or impractical to see directly, such as the ocean floor or the atomic surfaces of objects. Early in the history of oceanography scientists dropped weighted cables to the bottom of the ocean. By moving across the ocean at regular intervals and keeping track of how deep the…

Discusses the hydrodynamic reasons why a riverbed meanders through a plain. Describes how water movement at a bend in a river causes erosion and changes in the riverbed. Provides a mathematical model to explain the periodic shape of meanders of a river in a plain. (MDH)

Historically in the United States, few people with disabilities have enrolled in science-related courses or entered scientific careers in part because high schools and colleges have not offered accessible training to this population. This document is the teaching and resource guide that accompanies a 30-minute video program in career development…

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)

Presents the origin and mathematics of Hubble's Law of the expanding universe. Discusses limitations to this law and the related concepts of standard candles, elliptical galaxies, and streaming motions, which are conspicuous deviations from the law. The third of three models proposed as explanations for streaming motions is designated: The Great…

This book presents information, activities, and paper models related to aviation. Most of the models and activities included use a one page, single concept format. All models and activities are designed to reinforce, clarify, or expand on a concept, easily and quickly. A list of National Aeronautics and Space Administration (NASA) Center education…

This booklet is a program management tool designed for use by high school students and teachers participating in science research programs throughout the United States as well as overseas. The program consists of a symposium during which students are invited to conduct original research in the sciences, mathematics, humanities, and computer…

Science projects are a great way for students to learn more about science as they search for the answers to specific problems. This book offers guidance and provides ideas for students as they plan experiments, find and record information related to the problem, and organize data to find answers to the problem. The 20 topics in this book suggest…
