In this paper, an educational tool is proposed to show the internal photoelectric effect in a simple and clear way for Undergraduate Physics courses or High Schools. Experimental evidence of the photoelectric effect is particularly important in the didactic experience. This effect is fundamental to introduce students to the world of quantum…

Information and knowledge of science are very necessary and vital inputs for growth and survival in modern times. Science is a body of knowledge that can be rationally interpreted and applied consistently in human endeavors. Science as a form of information is a way to examine a process and a way of thinking in the quest for an understanding of…

A set of inexpensive and pedagogically rich experiments focusing on S[subscript N]1, E1, and E2 reactions have been updated to include modern computational and spectroscopic analyses. The S[subscript N]1 experiment involves treatment of "tert"-amyl alcohol with hydrochloric acid to generate the corresponding alkyl chloride, which is used…

School genetics is changing. Nowadays, students are more likely to be introduced to the idea that many characteristics of organisms, including those of humans, are not determined by the actions of just one or two genes but result from interactions between the products of many genes and the environments of each organism. This article asks whether…

An economy that grows is good. Growth in income is certainly good. In general, growth is seen as a good thing. A global pandemic challenges this notion. Let's be careful of what we wish for- especially if growth is "exponential." This article describes exponential growth and doubling time, and shows how these concepts can be related to…

Course specific learning outcomes are an important tool to define the scope of a course and can be very helpful when designing experiments and assessments. With slight modification, these learning outcomes can serve as a guide when transitioning to the distance learning format especially in courses with a traditional lab. Here we present such an…

The purpose of this study is to compare the instructional practices in science education in Malaysian and German secondary schools. Specifically, the objectives of this research are to seek answers for the following questions: (i) What are the current science teachers' instructional practices in German secondary school? (ii) What are the current…

We investigated the effect of retrieval practice (i.e., the use of testing to enhance learning) by middle school students on science learning in an authentic educational setting. For initial study, all students (n = 39) read a science text and made study notes about the text, a regular study activity in their course. For restudy (2 days later),…

A great deal has been written about the huge benefits to children of learning through the context of stories. Some scientific concepts can be difficult for children to understand if they cannot see or experience them. Stories help bring the concepts to life, making them more meaningful, increasing engagement and often providing a more fun…

In high school and elementary college physics labs the measurement of vertical distance is often required. Measuring the distance an object falls or the vertical displacement of springs in a Hooke's law experiment are commonplace. Determining these distances to perhaps a millimeter or two of precision is difficult without an expensive height gauge…

Gender bias and inequity are pervasive in physics, but teachers can help. A recent Resource Letter digs into the history, current status, and classroom implications of gender and physics. However, one finding from that work was the tendency for "gender in physics" research to treat sex and gender as the same thing and to neglect the…

Children often have very stereotyped views of science and scientists, far removed from their own lives. Getting children to 'become' scientists and feel that they are actually "doing" science, being involved in something pertinent to them and their environment, is a goal of modern science teaching. This article aims to illustrate how…

Teachers in Dorset and East Devon have the benefit of the Jurassic Coast on their doorstep to help them bring the 'rocks and fossils' content of the curriculum alive. Not only is the area breathtakingly beautiful, but it is also rich in educational resources. If schools are not in an area close enough to make a class visit possible, how can…

In this article, the author considers ecosystems in a much more holistic way and encourages children to consider how all the interactions within that ecosystem affect the balance of it. There is hardly an ecosystem on Earth that has not been somehow affected by human interaction. Humans are the ultimate ecosystem engineers, and it is important to…

Although making errors in the learning process is common, it is usually perceived by students as something negative and a potential threat to self-esteem. Such perception often prevents students from considering errors as learning opportunities. By using errors as integral elements of the learning process within the science classrooms, and…
