This paper shows how two distinct but related models can be used to bring out the essential physics of heat flow in one dimension. The first is a simple step-wise procedure using "SMath Studio," while the second is an electric analogue using a basic RC ladder connected to an Arduino microcontroller. Both models can be demonstrated in…

The aim of the current paper is to investigate the traces of socio-cognitive influences in kindergarten teachers' representations about the practices they tend to follow when they develop Natural Sciences activities in kindergarten. A quantitative approach was used, with the research tool being an electronic questionnaire that was completed online…

To help students acquire mathematics and science knowledge and competencies, educators typically use multiple external representations (MERs). There has been considerable interest in examining ways to present, sequence, and combine MERs. One prominent approach is the concreteness fading sequence, which posits that instruction should start with…

DNA structure has been leveraged in a variety of facets that allow scientists to perform a range of assays, including ones for identification of species, establishing evolutionary relationships between taxa, or even identifying individuals. Here, we present a DNA barcoding method as practical, hands-on approach that connects several experimental…

In this laboratory experiment, students evaluated three silver(I) complexes as potential additives for dental adhesives based on bacterial growth inhibition, heat stability, water insolubility, and cost-effectiveness. Each student prepared and analyzed a cyanoxime ligand and its corresponding silver(I) complex. Students characterized the…

Eliciting, noticing, and responding to students' sense-making is important for advancing students' understanding and fostering meaningful participation in science. By sense-making, we mean wrestling with ideas, language, experiences, and perspectives in a community to figure out how and why the world works. In the bustle of an elementary…

Research on the use of digital games suggests they can enhance students' learning; however, teachers often play an important role in mediating gameplay and a game's educational goals. The purpose of the study was to investigate implementation approaches of nine biology teachers using an immersive digital game in their science classes, focusing on…

Approaching elective courses and courses on special topics in Chemistry can seem daunting at times, given the varied backgrounds of the students, together with the broad nature of topics. Often, institutions may give incentives for creating sustainability related course offerings, but knowing where to start and how to organize the information…

In this study, it is aimed to develop practical teaching activities that can be used in optics teaching. For this purpose, a virtual laboratory environment was created in RayLab which is an application for design and simulation of optics on the iPad/iPhone. In this context, the dispersion of white light in the prism, the relationship between the…

Chaotic phenomena are not part of standard curricula, although this subject offers several interesting aspects which can help students better understand basic features of science. A central observation is that even simple physical systems, if chaotic, are unpredictable, just like the weather. We present the principles applied when developing a…

Although learning about Nature of Science (NOS) promotes a variety of important outcomes, teachers often lack suitable activities for younger students to effectively address NOS. In this article I elaborate on an NOS activity developed for a teacher professionalisation workshop. The activity is suited for younger students as well, where clear…

An analysis is presented in this study that provides insight into a practical training process and its impact on teachers and their viewpoints toward the integrated STEM approach used in that training process, together with educational coding and robotics, over the first years of compulsory primary education, where STEM implementations are…

One of the aims of primary education, as suggested by the Cambridge Primary Review, should be, 'Exploring, knowing, understanding and making sense'. It should give the children 'the opportunity to encounter, explore and engage with the wealth of human experience and the different ways through which humans make sense of the world and act upon it'.…

Chemistry is one of the important branches of science. The subject matter of chemistry consists of numerous complex and abstract concepts. Therefore, sometimes students have flawed understanding of these concepts. These erroneous concepts are known as misconceptions. The purpose of this study was to investigate the misconceptions for Valency and…

IUPAC nomenclature of lower alkanes (1C to 10C) is quite common and digestible. But students face problems remembering and predict IUPAC word-root during IUPAC nomenclature of higher alkanes (C >11). Here in this innovative article, I have tried to focus IUPAC nomenclature of higher alkanes (11C to 90C) through the prediction of IUPAC word root…
