This study aimed to teach 9th grade students the meanings of scientific theory and scientific law, and the differences between them. The related literature informs that students at different grade levels have misconceptions about the definition of both scientific theory and scientific law and the relationship between them. In this study, the…

Describing the motion in a vertical roller coaster loop requires a good understanding of Newton's laws, vectors and energy transformation. This paper describes how first-year students try to make sense of force and acceleration in this example of non-uniform circular motion, which was part of a written exam. In addition to an analysis of the exam…

The present study explores how in-service secondary education Greek biology teachers understand aspects of the concept of ecosystem under the assumption that the ecosystem is an ill-defined concept. If it is to be considered a holistic entity, the ecosystem acquires its definitional features within the ecological field of systems ecology, which…

University professors' views of nature of science play an important role when guiding undergraduate students into the culture of practicing physicists. While these topics have a long-standing tradition in U.S. curricula they are not part of German educational standards or curricula. Additionally professors' views--in contrast to those of their…

Understanding the nature of science (NoS) is perplexing for young children because it is concerned with not only understanding how evidence is generated but also what kind of meanings can be made from information collected. However, acting as a scientist-in-role, making independent decisions about what information to collect and deciding how to go…

A recent framework on nature of science (NOS) is the Family Resemblance Approach (FRA). FRA presents NOS as a cognitive-epistemic and social-institutional system with a set of categories: aims and values, scientific methods, scientific practices, scientific knowledge and social-institutional aspects of science. Although FRA has been problematised…

In this paper we present a pedagogical strategy to introduce the Heisenberg uncertainty principle to high school students. The basis on which this proposal relies is the Fourier transform, connecting the quantum function in the x domain, ?(x), with the function in the wave number domain, A(k). This mathematical relationship directly leads to the…

A "Framework for K-12 Science Education and the Next Generation Science Standards" ("NGSS") are intended for all students, hence "all standards, all students" (NGSS Lead States 2013). To make this vision a reality, the "NGSS" highlight three key instructional shifts: (1) explain phenomena or design solutions…

Recent research on science teaching and learning defines science as both a body of knowledge and a process (NRC 2007); it is the integration of science content, practices, and core ideas (NRC 2012). It would follow that science learning should parallel what science is and how it is done; students should not be just consumers of scientific…

This study is based on the Reconceptualised Family Resemblance Approach to Nature of Science (Kaya & Erduran, 2016), which explains science as a cognitive, epistemic, and social-institutional system. A content analysis of Turkish science curricula shows that the social context of science is underemphasised (Kaya & Erduran, 2016).…

In this study, we probed high school students' understanding of Einstein's theory of gravity by implementing an approach which mainly consists of two steps: firstly, exposing students to TEs describing the Equivalence Principle; secondly, applying the analogy of parallel lines on a curved surface with the path of two falling balls in a real…

Using everyday life examples is proven didactically useful for teaching physics, as it presents effective applications of physical laws. Cooking and food, in particular, serve two useful purposes: on one side, they are able to engage students in the study of physics with familiar examples; on the other side, thanks to the wide range of physical…

An undergraduate teaching laboratory experiment involving a continuous flow, photocatalytic thiol-ene reaction using visible-light irradiation is described that allows students to explore concepts of green chemistry, photochemistry, photocatalysis, and continuous flow chemistry.

This work focuses on the experimental demonstration of the hydrostatic paradox using simple tools in the form of plastic bottles and plastic syringes with a thread. For the evaluation of the results obtained the data logger Lab Quest Vernier was used. The construction of the device is presented in the first part of this paper. The second part…

Environmental Data-Driven Inquiry and Exploration (EDDIE) modules engage students in analysis of data collected by networks of environmental sensors, which are used to study various natural phenomena, such as nutrient loading, climate change, and stream discharge. We compared two approaches to EDDIE module implementation in an undergraduate…
