There are many reasons for exposing physics students to primary source material in the sciences. These works can illuminate the history of science and give students a more vivid picture of the development of physics than most textbooks attempt to provide. They can also serve as pedagogical tools for exploring the misconceptions and "wrong…

Spontaneity criteria for processes with useful (especially electrical) work have been discussed based on total differentials of thermodynamic functions. Reaction Gibbs energy ([Delta][subscript r]G) and electrochemical reaction Gibbs energy ([Delta][subscript r]G~) have been juxtaposed. Three-dimensional graphs showing the dependencies of…

Colorimetry allows every color to be defined as a combination of three values, known as "color coordinates." Color coordinates allow researchers to universalize and standardize their color measurements, and nowadays, determining the color coordinates of samples is a routine method applied by organic and analytical chemists, students, and…

Three-dimensional printing was used to prepare a p-bonding model with embedded magnets. The model enables students to have a kinesthetic experience that simulates the energetics of bonding, antibonding, and nonbonding p-orbital interactions.

Purpose: The purpose of the study is to develop a Scaffolded Mastery Learning (ML) module in cell division topic for both teachers and students and study its impacts in teaching and learning process. Method: The study employed Sidek Module Development model in developing the modules. Three expert teachers and ten Form 4 students were involved in…

The planets in our solar system are remarkable and captivating objects for beginning astronomers to study. While merely observing the planets is fairly easy, it can be difficult to capture the high-quality images beginners hope for. The methods used for deep-sky astrophotography are optimized for dim, fairly large objects using large apertures and…

This manuscript presents a content analysis of 28 picture books from the Outstanding Science Trade Books recognized by the National Science Teachers Association in 2016. Drawing on the need for culturally relevant science instruction, the research investigated the portrayal of scientists in images (gender and racial background), the scientific…

Infographics present information or data in an accessible and concise manner to help a viewer understand a phenomenon. Creating infographics requires students to make sense of multiple sources of data and synthesize these data into a compelling visual form to make a central claim. Unlike posters, which tend to be purely informational with…

This paper describes a cost effective and safe device to perform realistic experiments on the physics of radioactivity in classrooms. It can be used to study both a- and ß-radioactivity as well as ?-emitters and shows extremely realistic behaviour. The device, in the form of a Geiger--Müller tube, was tested during a public lecture and it deceived…

Recently, infrared cameras have become available as smartphone accessories. Being less expensive than regular infrared cameras they are readily affordable for schools and many teachers may even privately own one due to their potential to visualize all kinds of thermal phenomena in physics teaching. Any science teacher who wants to use such a…

Students have been taught that atmospheric temperature drops linearly with altitude, up to approximately 15 km. However, even after completing an undergraduate degree program, most students have only memorized such information and have never had the experience of measuring it. Students often assume that experimental tasks must involve the use of…

We argue that students should take on roles as "epistemic agents"--those who shape knowledge production and practices of a community. In this study, the research team--a science educator and two scientists--worked with a sixth-grade teacher to provide 90 students with opportunities to take up epistemic agency over a 22-day unit about…

This paper describes a pictorial approach to Lenz's law that involves following four steps and drawing three pictures to determine the direction of the current induced by a changing magnetic flux. Lenz's law accompanies Faraday's law, stating that, for a closed conducting loop, the induced emf (electromotive force) created by a changing magnetic…

The saga of the search for the ultimate constituents of matter has long been one of finding a seemingly fundamental structure that, in turn, was found to be made of even smaller building blocks. Matter is made of molecules. Molecules are in turn made of atoms, which are themselves made of electrons and atomic nuclei. The nucleus consists of…

Physiology education research aims to investigate teaching-learning aspects and methods specifically applied to physiology teaching and learning. In this paper exploring Brazilian research public data and information from the Brazilian Physiological Society Teaching Committee, we investigated the status of this research topic (physiology…
