The purpose of this study was to explore the understandings of prospective early childhood teachers on scientific knowledge and scientific method. The study was interpretive in nature. The data were collected through various open-ended questions with subsequent auxiliary ones directed towards ten participants during a combination of in-depth focus…

In this article we consider the well-known demonstration of friction by two interleaved books. We consider a factor that has not been part of the popular explanation--atmospheric pressure. We provide three control experiments to demonstrate the role of atmospheric pressure in the two-book experiment and an additional simple demonstration of the…

Reconnecting to nature is imperative for the sustainability of the planet and outdoor experiential programs are an ideal context to operationalize and study sustainability interventions. The purpose of this research is two-fold. First, we investigate the extent to which types of connections to nature are expressed by participants who completed an…

Nature of science (NOS) has been a central theme in science education and research on it for nearly three decades, but there is still debate on its proper focus and underpinnings. The focal points of these debates revolve around different ways of understanding the terms "science" and "scientific knowledge". It is suggested here…

The purpose of this study is twofold: first, to delve into professional development (PD) of science teachers' views about nature of science (NOS) throughout activities linking NOS aspects to science centers (SCs), and second, to reveal how a science teacher uses NOS aspects while teaching in SCs. An instrumental qualitative case study method with…

This study aims to categorize the scenarios designed on socio-scientific issues (SSIs) by prospective teachers who participated in an SSI-based instructional practice and to analyze these scenarios in terms of representing the nature of science (NOS) components. Sample of the study comprised SSI scenarios written by 30 third-year prospective…

Epistemological beliefs, including the source of knowledge, the certainty of knowledge, the organization of knowledge, the control of learning, and the speed of learning, are important to identify since these beliefs impact students' learning processes and how they attribute meaning to life. Concept cartoons, that students find genuine and…

In primary and secondary schools, the disciplines encompassed in "STEM"--Science, Technology, Engineering and Mathematics--have usually been studied as separate subjects, with little effort directed towards non-anecdotal integration. "Integrated STEM education" is one of the most recent interdisciplinary proposals and, under…

Conrad Hal Waddington (1905--1975) was an English biologist who was especially interested in the big (metaphysical) questions of life. His thinking has become part of the foundation of modern systems biology. This article applies his thinking to middle-years school biology curricula (for ages 11-16), to see if their approach to epistemic questions…

This study focuses on designing a laboratory learning program for a high school chemistry course in which students could discover the fundamental principles of Hess's law via stepwise inquiry. By exploring the chemical properties of common desiccants, mainly those that were reactive in water, students were introduced to the exothermic reaction of…

The aim of this research was to establish the effects of argumentation and the quality of arguments related to history of the development of organic chemistry: (i) on the level of the pupils' knowledge about the composition, structure and general properties of organic compounds; and (ii) on their perception of the key aspect of NOS that scientific…

In this paper, the inclusion of history and philosophy of science in science teaching is proposed with the goal of depicting pre-service primary teachers' perception of the role of historical experiments in learning science and the nature of science. In order to achieve this, a teaching-learning sequence was designed and conducted in the context…

Science continuously interacts with the social environment. Science develops with social needs, and society develops and changes with scientific advances. These changes and developments may cause dilemmas in society. Thus, the purpose of this study is to investigate the improvements among pre-service science teachers in terms of socio-scientific…

The methodology and mathematical treatment of several classic multivariate methods for the analysis of spectroscopic data is demonstrated in a straightforward way that can be used as a basis for teaching an undergraduate introductory course on chemometric analysis. The multivariate techniques of classical least-squares (CLS), principal component…

The paper reports about a study that examines changes in teachers' incorporation of epistemic practices in their design of engineering lessons and compares them to their views about the nature of engineering knowledge across 100 hours of professional development. Nineteen K-8 teachers in the USA, who were new to teaching engineering as part of a…
