Saglam-Arslan, Aysegul; Devecioglu, Yasemin – Asia-Pacific Forum on Science Learning and Teaching, 2010
This study was conducted to determine the level of student teachers' understandings of Newton's laws of motion and relating these levels to identify student teachers' models of understanding. An achievement test composed of two parts comprising 12 open ended questions was constructed and given to 45 pre-service classroom teachers. The first part…

Geisinger, Kurt F. – Assessment in Education: Principles, Policy & Practice, 2016
The six primary papers in this issue of "Assessment in Education" emphasise a single primary point: the concept of validity is a complex one. Essentially, validity is a collective noun. That is, just as a group of players may be called a team and a group of geese a flock, so too does validity represent a variety of processes and…

Rodrigues, Hilário; Panza, Nelson; Portes, Dirceu; Soares, Alexandre – Physics Education, 2014
This paper is essentially about the general form of Newton's second law for variable mass problems. We develop a model for describing the motion of the one-dimensional oscillator with a variable mass within the framework of classroom physics. We present a simple numerical procedure for the solution of the equation of motion of the system to…

Theilmann, Florian – Physics Education, 2014
In a typical high school course, the complex physics of collisions is broken up into the dichotomy of perfectly elastic versus completely inelastic collisions. Real-life collisions, however, generally fall between these two extremes. An accurate treatment is still possible, as demonstrated in an investigation of coin collisions. Simple…

Sauerheber, Richard D. – International Journal of Mathematical Education in Science and Technology, 2012
Methods of teaching the Calculus are presented in honour of Sir Isaac Newton, by discussing an extension of his original proofs and discoveries. The methods, requested by Newton to be used that reflect the historical sequence of the discovered Fundamental Theorems, allow first-time students to grasp quickly the basics of the Calculus from its…

Ergin, Serap – Journal of Education and Training Studies, 2016
In this study, the effect of group work and traditional method on 9th grade students' misconceptions about Newton Laws was investigated. The study was conducted in three classes in an Anatolian Vocational High School in Ankara/Turkey in the second term of the 2014-2015 academic year. Two of these classes were chosen as the experimental group and…

Fischer, Joyce; Wayment, Stanley; Johnson, Christopher – PRIMUS, 2010
Making connections is one of the most important foundations involved in learning mathematics. Two projects are presented in this article: one involving Newton's Second Law of Motion and the other involving the determination of star numbers, a type of figurate number. The two invoke seemingly different modalities for students at different levels of…

Haugland, Ole Anton – Physics Teacher, 2019
Students should have a strong conceptual understanding of the connection between force and acceleration before they start working with applications and problem solving. This has been discussed in the literature. During these days of flipped classroom instruction, an at-home activity could be especially valuable. I will describe an experiment with…

Mihail, Michael D.; George, Thomas F.; Feldman, Bernard J. – Physics Teacher, 2008
This article describes an experiment that measures the forces acting on a flying bird during takeoff. The experiment uses a minimum of equipment and only an elementary knowledge of kinematics and Newton's second law. The experiment involves first digitally videotaping a bird during takeoff, analyzing the video to determine the bird's position as a…

Gokalp, Muhammed Sait; Sharma, Manjula; Johnston, Ian; Sharma, Mia – Teaching Science, 2013
The purpose of this study was to investigate how WebQuests can be used in physics classes for teaching specific concepts. The study had three stages. The first stage was to develop a WebQuest on Newton's second law. The second stage involved developing a lesson plan to implement the WebQuest in class. In the final stage, the WebQuest was…

Lee, Han Su; Park, Jongwon – International Journal of Science and Mathematics Education, 2013
Finding out about and then understanding the forces acting on a moving object, based on a description of the change in motion of this object, is an important part of the conceptual understanding of Newton's law of motion. Using Hempel's deductive-normative model for scientific explanation, we developed a deductive explanation task (DET),…

Eisenstein, Stanley – Science Teacher, 2008
First-year physics students often have a difficult time grasping Newton's laws of motion and recognizing the forces that these laws depend on. The "Paper Car" project is an experiential activity that is rich in application of force principles. It is also simple enough that students are able to integrate straightforward but non-trivial physics…

Shepard, Roger N. – Cognitive Science, 2008
Examples from Archimedes, Galileo, Newton, Einstein, and others suggest that fundamental laws of physics were--or, at least, could have been--discovered by experiments performed not in the physical world but only in the mind. Although problematic for a strict empiricist, the evolutionary emergence in humans of deeply internalized implicit…

Gauld, Colin F. – Science & Education, 2006
Newton's Cradle is a series of bifilar pendulums used in physics classrooms to demonstrate the role of the principles of conservation of momentum and kinetic energy in elastic collisions. The paper reviews the way in which textbooks use Newton's Cradle and points out the unsatisfactory nature of these treatments in almost all cases. The literature…

Binder, P.-M.; Magowan, M. A. – Physics Teacher, 2016
In this note we unify two physical situations treatable with hydrostatics: an object floating on a denser fluid and an open U-shaped tube with two immiscible fluids. We begin by reviewing the problem of a partially floating uniform, rectangular prism of horizontal area "A" immersed in a denser fluid, with respective densities ?[subscript…
