Understanding the nature of scientific inquiry is considered a critical component of scientific literacy [Michaels, S., Shouse, A. W., & Schweingruber, H. A. (2008). "Ready, set, science!: Putting research to work in K-8 classrooms." National Academies Press]. What do elementary students already know about scientific inquiry? Using…

It is proposed a network approach for electric circuits simplification, that through a unified systematic procedure allows simplifying circuits of any complexity, and evaluation of the equivalent resistances, capacitors and inductors. Circuits to be simplified are characterized by their nodes, and by the elements of different types (resistances,…

Environmental science classes often ask students to examine changes in species or their environments to determine the human impact on a particular habitat or ecosystem. It is not always practical to take students out for a field study to do this kind of analysis; instead, the scientific method and diversity analyses can be utilized while students…

Research indicates that teachers lack a sophisticated understanding of Nature of Science (NOS), which in turn, can impact their instructional decisions and students' understanding of NOS. The aim of the study was to investigate United Arab Emirates (UAE) early years' science teacher's (N = 433) perceptions about the NOS. Results obtained from a…

Written as a letter to Galileo, an education graduate student narrates from course experiences that deepened her understandings of Galileo and natural and intellectual properties underlying his works. Having taken the Galileo-themed course with Elizabeth Cavicchi at MIT's Edgerton Center in three prior terms, on taking it a fourth time, this…

This study examines the contribution of the knowledge produced in educational administration doctoral theses to the functions of science, concept and model development, theory formation, scale development/adaptation and application. Content analysis, one of the qualitative methods, was used in conducting the research, which analyzed 122 doctoral…

Science education and scientific literacy has gained enormous attention in the global educational scenario. In many cases, however, the holistic intent of science education is largely affected due to the lack of adequate understanding of the Nature of Science (NOS). This cross-sectional study was carried out to establish Bhutanese pre-service…

In this paper, I combine feminist, decolonial scholar María Lugones' theory on playfulness and world-traveling with feminist science studies scholar Deboleena Roy's work along with some other core feminist science studies concepts to define feminist tinkering as an explicitly politically motivated "playing" with the epistemic power of…

A significant approach that should be followed by physics teachers at the secondary education level in order to enhance students' understanding is to highlight the generality of the mathematical procedures that describe different physical phenomena. In this paper, the common procedure that is used to calculate the duration of various physical…

Reconceptualized Family Resemblance Approach to Nature of Science (RFN) explains science as a cognitive, epistemic, and social institutional system. The aim of this study is to examine the inclusion of Nature of Science (NOS) in the 5th, 6th, 7th, and 8th grade Turkish middle school science textbooks. The "content," "activity,"…

Properly made solutions are critical to the scientific method. However, in various laboratories and collaborative environments, we have noticed a lack of proper technique for making solutions. Instead of measuring the moles of solute then filling up to the needed volume with solvent, we observed many individuals would measure the moles of solute…

To obtain a general understanding of science, model use as part of National Education Standards is important for instruction. Model use can be characterized by three aspects: (1) the characteristics of the model, (2) the integration of the model into instruction, and (3) the use of models to foster scientific reasoning. However, there were no…

The paper presents an empirical study on university students' perceptions of nature of science (NOS). NOS is framed in terms of the cognitive, epistemic, and social-institutional systems of science based on the Family Resemblance Approach (FRA) (Erduran and Dagher 2014; Irzik and Nola 2014; Irzik and Nola, SCED 20:591-607, 2011). FRA includes the…

The Clemmensen reduction is a common example of a reaction demonstrating the deoxygenation of carbonyl groups, which is a topic that has been widely studied in the field of organic chemistry. The use of trimethylchlorosilane, as a substitute for concentrated hydrochloric acid, allows for the reduction of carbonyl groups. The Clemmensen reduction…

A new Pew Research Center survey finds that many Americans can answer at least some questions about science concepts -- most can correctly answer a question about antibiotics overuse or the definition of an "incubation period," for example. But other concepts are more challenging; fewer Americans can recognize a hypothesis or identify…
