The whole mode of Galileo's discovery of the Law of Inertia is an excellent exemplar of the Nature of Science. The law can, moreover be shown to be a direct consequence of the hypothesis that space is homogeneous and isotropic and time is homogeneous.

A model for engaging undergraduates in cutting-edge experimental nuclear physics research at a national user facility is discussed. Methods to involve students and examples of their success are presented. (Contains 2 figures and 3 tables.)

Our school has a very small budget for equipment. So finding a gem like a conservation of momentum lab requiring only basic materials ("TPT", October 2005) adds a great deal to my physics course. In this lab, a "shooter" nickel makes a non-head-on collision with a stationary "target" nickel. Students measure the distance each nickel slides after…

This study examines changes in kindergarten students' understanding of energy after participating in a series of lessons developed using an inquiry-based early childhood science teaching model: Research-based Inquiry Physics Experiences (RIPE). The lessons addressed where objects get their energy and what they use their energy to do, and how…

We use the theory of communities of practice and the concept of accountable disciplinary knowledge to describe how a learning community develops in the context of an upper-division physics laboratory course. The change in accountable disciplinary knowledge motivates students' enculturation into a community of practice. The enculturation process is…

Given the increasing costs associated with commercial textbooks and decreasing financial support of public schools, it is important to better understand the impacts of open educational resources on student outcomes. The purpose of this quantitative study is to analyze whether the adoption of open science textbooks significantly affects science…

Since 2003, international project PISA evaluates 15-year old students in solving problems that include "decision taking", "analysis and design of systems" and "trouble-shooting". This article presents the results of a pilot research conducted with 215 students from first to fourth grade of a high school in Sarajevo…

More than a thousand Grade 10 Physical Science learners from four South African provinces participated in a study that probed their conceptions of energy. The purpose was to determine the learners' conceptual resources, i.e. their initial conceptions, and identify the potentially productive resources from which they may construct physics concepts.…

In the fall of 2008 the authors contacted a representative sample of over 3,600 high schools in the United States, both public and private, to determine whether or not physics was taught there. They received responses from over 99% of the schools. For the schools which indicated they were offering physics, the authors obtained contact information…

This study explores the nature of undergraduate students' errors and misconceptions in particle mechanics. This paper provides in-depth descriptions of the errors presented by students and accounts for them in terms of students' procedural or conceptual knowledge. Specifically, this study analyses students' written responses to questions on…

This study examines prospective teachers' levels of understanding the photoelectric effect, and the impact of writing activities for learning purposes on the success of prospective teachers. These prospective teachers study in the science teaching program of the faculty of education and take the course Introduction to Modern Physics. In this…

Four science programs at our public urban liberal arts college have struggled to attract and retain majors: physics, environmental studies, geology, and teaching science. The Brooklyn Opportunities in Science and Careers (BOSC) program aims to increase student participation in these majors using a new career-focused strategy to recruit students.…

In this article, I will extend the falling ball method to measure the viscosity of liquids regardless of the degree of their viscosity. For this, I will show that one can obtain a measurement of the terminal velocity of a falling spherical ball in a viscous liquid by solving numerically the equation of motion which describes the dynamics of the…

The research outlined in this paper investigated how student teachers perceived the development of their knowledge and attitudes towards physics through video recorded practical workshops based on experiments and subsequent group discussions. During an 8-week physics course, 40 primary science student teachers worked in groups of 13-14 on…

Ongoing professional development for college teachers has been much emphasized. However, previous research on learning environments has seldom addressed college students' perceptions of teachers' PCK. This study aimed to evaluate college students' perceptions of a physics teacher's PCK development using a newly developed instrument and workshop…
