An attempt to calibrate a conventional oven led to making a measurement of a thermophysical property of water using items found in the author's home. Specifically, the ratio of the energy required to heat water from the melting point to boiling to the energy required to completely boil away the water is found to be 5.7. This may be compared to the…

The Tasks Inspired by Physics Education Research (TIPERS) workbooks pose questions in styles quite different from the end-of-chapter problems that those of us of a certain age were assigned back in the days before Netscape. My own spin on TIPERS is not just to do them on paper, but to have students set up the situations in the laboratory to…

Water exhibits a maximum in density at normal pressure at around 4° degree temperature. This paper demonstrates that during cooling, at around 4 °C, the temperature remains constant for a while because of heat exchange associated with convective currents inside the water. Superficial approach implies it as a new anomaly of water, but actually it…

This study was prepared to investigate prospective biology teachers' cognitive structures related to "water". As the research design of the study, the case study was applied. The data were collected from 44 prospective biology teachers. The free word-association test, the drawing-writing technique and the semantic differential attitude…

This article presents and discusses an innovative pedagogical device designed for training pre-service teachers on the nature of science. We endorse an approach according to which aspects of the nature of science should be explicitly discussed in order to be understood by learners. We identified quantum physics, and more precisely the principles…

The ability to accurately reason using three-dimensional visualizations is vital to success in STEM disciplines, particularly the geosciences. One impediment to learning from visualizations is spatially-based misconceptions. Such errors can arise from a range of sources (e.g., prior beliefs, inaccurate application of analogy, and visual…

This work presents experiments to teach fundamentals of automation through a sequence of laboratory practices that naturally guide to development of an on/off control system. It focuses on the integration of technological and scientific concepts, based on an educational approach associated with a problem-solving technique.

The well-known historical development of Electromagnetism, strongly influenced by the work of Faraday and Maxwell, has led to the introduction of the magnetic field as an important component to explain the diverse phenomena of electromagnetic induction. This historical development is compared in the form of a thought experiment with a possible…

Quadcopters (also known as "drones") do not fly in vacuum. This is obvious enough that experimenting on one in a vacuum chamber would seem rather uninteresting, but there is one question that may be usefully addressed by such an experiment: the mechanism for yaw control. Quadcopters control yaw (rotation about the vertical axis) by…

This paper provides a brief introduction to antimatter and how it, along with other modern physics topics, is utilized in positron emission tomography (PET) scans. It further describes a hands-on activity for students to help them gain an understanding of how PET scans assist in detecting cancer. Modern physics topics provide an exciting way to…

Science learning for undergraduate students requires grasping a great number of theoretical concepts in a rather short time. In our experience, this is especially difficult when students are required to simultaneously use abstract concepts, mathematical reasoning, and graphical analysis, such as occurs when learning about RC circuits. We present a…

P-n junctions form the basic building blocks for any semiconductor device. Therefore, the complete understanding of the junction characteristics is very important. Although being a widely discussed topic in electronics, there are still some gaps such as finding the value and significance of the junction ideality factor, that needs to be addressed.…

Research in developmental psychology has shown that deeply-rooted, intuitive ways of thinking, such as design teleology and psychological essentialism, impact children's scientific explanations about natural phenomena. Similarly, biology education researchers have found that students often hold inaccurate conceptions about natural phenomena, which…

Nowadays, in almost any country in the world, it is difficult to find a young person who has never played with, seen, or heard of the most famous toy in 2017: the fidget spinner. According to Wikipedia: "The fidget spinner is a toy that consists of a ball-bearing in the center of a multi-lobed flat structure made from metal or plastic…

The Royal Society of Biology is working with the bioscience community, and researchers and practising teachers in the education community, to inform its position on a coherent 5-19 framework to support future biology curriculum development. Our approach taken in developing the framework has been 'evolution not revolution', mapping existing…
