Newton's laws of mechanics are a cornerstone in the development of modern science and its learning can be the very first opportunity for students to defy their common sense perceptions and replace them with a more robust world view. However, despite their fundamental importance, many studies demonstrate how difficult is the true comprehension of…

This research examines viewpoints held by pre-service science teachers on key concepts of the Nature of Science (NoS) in the Saudi context. Much research in this context emphasises quantitative methods, so this research utilises methodological triangulation to validate the data. Quantitative data was first obtained from 35 pre-service teachers…

How do scientists make inferences for something they cannot directly observe? The Black Box approach seems ideal to help students understand how scientists work. Black Boxes are sealed units; their interior is not accessible. The effort to determine their possible content (internal structure) demands successive modifications in hypothesis,…

Science teacher's self-efficacy has been at the center of many investigations on students' achievement in science, teacher burnout, and teacher performance. While overly studied, this construct has not been examined with scientific literacy in depth. Thus, this study aims to identify the influence of science teacher's scientific literacy on their…

"For every action there is an equal and opposite reaction." "Except when a bug hits your car window, the car must exert more force on the bug because Newton's laws only apply in the physics classroom, right?" Students in our classrooms were able to pick out definitions as well as examples of Newton's three laws; they could…

We briefly discuss the philosophical basis of science, causality, and scientific evidence, by introducing the hidden but most fundamental principle of science: the similarity principle. The principle's use in scientific discovery is illustrated with Simpson's paradox and other examples. In discussing the value of null hypothesis statistical…

This column presents ideas and techniques to enhance your science teaching. This month's issue shares information on how students' everyday experiences can support science learning through engineering design. In this article, the authors outline a reverse-engineering model of instruction and describe one example of how it looked in our fifth-grade…

The aim of this research is to determine what differences may exist in students' structural knowledge while using a variety of concept mapping assessments. A concept map can be used as an assessment which connects concepts in a knowledge domain. A single assessment may not be powerful enough to establish how students' new knowledge relates to…

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…

The mechanical energy change of a system in an inertial frame of reference equals work done by the total nonconservative force in the same frame. This relation is covariant under the Galilean transformations from inertial frame S to S', where S' moves with constant velocity relative to S. In the presence of nonconservative forces, such as normal…

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…

The inclusion of engineering standards in US science education standards is potentially important because of how limited engineering education for K-12 learners is, despite the ubiquity of engineering in students' lives. However, the majority of learners experience science education throughout their compulsory schooling. If improved engineering…

The present study specifically focuses on science teachers' views about scientific inquiry and their use of scientific inquiry in their lesson plans, which were prepared at a professional development workshop designed for better utilization of science centers (SCs). As an impact evaluation research, qualitative data was collected from 41…

Here we present an inexpensive proposal to experimentally study Faraday's law of induction. The experiment uses low-cost materials, a computer with a sound card and a smartphone, both running free software. A value proportional to the induced electromotive force is measured with the computer's sound card and the data related to the magnetic field…

The article is devoted to the analysis of the modern state of ethics of science. The question is raised regarding the possibility and problems of the interference of ethics in scientific rationality. From a philosophical position, preliminary answers are given to the following questions: How is it possible to incorporate ethics into the scientific…
