Revision can be a rather dull part of the academic year, especially if it means the wholesale revisiting of the syllabus using the same old notes. This article presents an attempt at using the "biography" of an element to give an alternative framework for recapping some of the key concepts in a typical A-level chemistry syllabus. It does…

In 1930, Einstein argued against the consistency of the time-energy uncertainty relation by discussing a thought experiment involving a measurement of the mass of the box which emitted a photon. Bohr seemingly prevailed over Einstein by arguing that Einstein's own general theory of relativity saves the consistency of quantum mechanics. We revisit…

Nearly two centuries ago, Fourier discovered that any periodic function of period T can be presented as a sum of sine waveforms of frequencies equal to an integer times the fundamental frequency [omega] = 2[pi]/T (Fourier's series). It is impossible to overestimate the importance of Fourier's discovery, and all physics or engineering students…

I describe a design-based learning activity that utilizes the interdisciplinary content domain of biomimicry. Design-based learning requires student creativity and technological innovation to address novel science problems, characteristics of the nature of science not often addressed in schools. Alignment with national standards documents,…

This study compares the inquiry competence of the 8th-grade students participating in the science and environmental education program GLOBE in the Czech Republic with a sample of students of the same age not participating in the program from the Slovak and Czech Republics. Inquiry competence is analyzed as a set of variables representing students'…

Worldwide studies have revealed an important issue in that an increasing percentage of students within the X-Y age group are not interested in science. Many students, especially females, have negative feelings and attitudes toward science, which discourages them from continuing with scientific inquiries. There are limited studies related to the…

The aim of this study was to improve the criterion-related test score interpretation of a text-based assessment of scientific reasoning competencies in higher education by evaluating factors which systematically affect item difficulty. To provide evidence about the specific demands which test items of various difficulty make on pre-service…

We have heard many times that the commonsense world of classical physics was shattered by Einstein's revelation of the laws of relativity. This is certainly true; the shift from our everyday notions of time and space to those revealed by relativity is one of the greatest stretches the mind can make. What is seldom appreciated is that the laws of…

New media technology becomes more and more important for our daily life as well as for teaching physics. Within the scope of our N.E.T. research project we develop experiments using New Media Experimental Tools (N.E.T.) in physics education and study their influence on students learning abilities. We want to present the possibilities e.g. of…

During a five-year period the authors taught over 100 students in a graduate course (The Nature of Science) counting toward teacher certification at the Harvard Graduate School of Education. Despite the fact that students had undergraduate degrees in the sciences, most of them found the application of models in science challenging and the…

Research on expertise suggests that a critical aspect of expert understanding is knowledge of the relations between domain principles and problem features. We investigated two instructional pathways hypothesized to facilitate students' learning of these relations when studying worked examples. The first path is through self-explaining how…

The purpose was to examine NOS knowledge and pedagogical content knowledge about NOS of in-service secondary science teachers. Data sources included Views of Science and Education scale, lesson plans with rationales for choices, examples of student work products, videotapes of lesson peer reviews, and interviews conducted after the experience.…

Providing sustainable mobility is a major challenge that will require new vehicle and fuel technologies. Alternative and future fuels are the subject of considerable research and public interest. A simple approach is presented that can be used in science education lectures at the high school or undergraduate level to provide students with an…

In order to design two distinct engineering qualification levels for an existing University of Technology programme, empirical evidence based on the current diploma is necessary to illuminate the nature of and the relationship between the "contextual" and "conceptual" elements underpinning a multidisciplinary engineering…

Inquiry-based classroom is widely distributed in the school science based on its useful and effective instruction. Science teachers are key elements allowing students to have scientific inquiry. If teachers understand and imply inquiry-based learning into science classroom, students will learn science as scientific inquiry and understand nature of…
