The Making Introductory Courses Real while Online (MICRO) laboratory project was developed to meet the need for hands-on experiments, focused on topics in analytical chemistry, to be delivered safely remotely or in a socially distanced in-person lab. Unlike more traditional lab experiments, MICRO laboratories use only microgram or nanogram amounts…

The problem of this study was the lack of problem-solving skills in early childhood, mostly in developing countries including Indonesia. This study examines the effect of the scientific approach-based learning process on problem-solving skills of early childhood and analyse the effectiveness of scientific approach-based learning to improve problem…

The use of serious educational games has the potential to increase student learning outcomes in science education by providing students with opportunities to explore phenomena in ways that vary from traditional instruction; yet, empirical research to support this assertion is limited. This study aimed to explore deeply what learning gains were…

The purpose of this study was to evaluate a form of writing instruction designed to teach second-graders to write compare and contrast informational texts. 73% of the participants (N = 45) were White, 22% were Hispanic, 2% were Asian, and 1% were Black, with 63% of the students eligible for free or reduced lunch. 48% of the students were female…

The paper describes our research aimed to verify the durability of pupils' initial ideas and concepts on the issue of acids and bases. First, we mapped their existence among primary school pupils and then compared them with the ideas of secondary and university educated adults. It has been confirmed that some initial ideas are very lasting and are…

Science educators are increasingly using a historical approach to pedagogy as a way to enable students to understand the process of the construction of science in a more contextualized manner. Considering the meaning of context in a broader sense, this article has two objectives. First, it aims to explore how physics lessons using a Cultural…

The purpose of this research was to identify physics concepts embedded in "moke" making process. The research was conducted in Munerana village, Flores Island, East Nusa Tenggara province, Indonesia. The research data were mainly obtained through in-depth interviews and direct observations at the location of "moke" making…

Students may have some confusion understanding certain physical concepts and principles because of their abstract nature. Using analogies is one of the useful methods to help them more easily grasp abstract concepts to promote conceptual understanding. Bilaloglu classified analogies in four groups: (a) simple analogies, (b) storified analogies,…

This paper addresses a popular topic in science teaching and competitions for primary and secondary school students. Experiments with colliding coins are relatively easy to perform and therefore popular in science lessons. We used the idea in the science competition we organized for pupils aged 6 to 13 years.7 The science competition is based on a…

This paper explores the influence of Science Teaching Orientations (STOs) on Teacher Professional Knowledge (TPK) domains of five in-service Malawian secondary school science teachers. The study was grounded within Friedrichsten et al.'s (2011) definition of STOs and Gess-Newsome's (2015) conceptualization of TPK. We gathered data using…

As a result of recent technological developments, many mobile applications used in the educational environments have emerged. One of these applications is the augmented reality technology used in smartphones and tablets. Many augmented reality applications are now prepared with 4Dtechnology and are employed to transform virtual environments into…

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…

Due to the COVID-19 pandemic we were confronted with the transition of a large, on-campus introductory soil science course into an online setting. This created several challenges, such as providing meaningful learning experiences to engage first- and second-year students, and restructuring course content for the online environment. The objective…

This research focuses on chemistry teachers' enacted pedagogical content knowledge (ePCK) in equilibrium in chemical reactions. The enactment dimension of this pedagogical content knowledge (PCK) encompasses enacted knowledge and skills as well as those embedded in practice concerning the Refined Consensus Model of PCK, the most recent PCK model…

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…
