This work presents a sequence to introduce resistive gas sensors in the classroom. It explains the physical principle of the metal oxide semiconductor sensors and exemplifies its real interfacing through the sensor model MQ-2. Besides, it also presents the design of two electronic systems to indicate the level of alcohol concentration in the air,…

Over the past few decades a growing awareness has developed in the science education community about the educational power of the history of science. Yet, the historical approach is not implemented in many ministries of education policies. In order to investigate what factors contribute to this, we have conducted a survey of attitudes toward the…

Brewe, Bruun, and Bearden first applied network analysis to understand patterns of incorrect conceptual physics reasoning in multiple-choice instruments introducing the module analysis for multiple-choice responses (MAMCR) algorithm. Wells et al. proposed an extension to the algorithm which allowed the analysis of large datasets called modified…

At the end of the 18th-century, Charles Coulomb developed an apparatus to study the force between two electrified beads which allowed him to obtain his famous Coulomb's law. Today, as one of the most fundamental outcomes in classical electromagnetism, his result is revisited in most high school physics courses, where students are asked to…

In the same chapter of his book "Opera Geometrica," Torricelli published two discoveries: 1) initial velocity of a jet from a container increases with the square root of the depth of the hole; 2) he drew the pattern of jets from three openings at the wall of a container filled with water to constant level "H" and determined the…

Blood flow through the cardiovascular system is governed by the same physical rules that govern the flow of water through domestic plumbing. Using this analogy in a teaching laboratory, a model of the cardiovascular system constructed of pumps and pipes was used to demonstrate the basic interactions of pressure, flow, and resistance in a regulated…

In the Spring of 2020, Embry-Riddle Aeronautical University (ERAU) physics faculty used the rapid response and change of teaching modality to the pandemic to holistically re-imagine the course assessments. They developed and implemented a course architecture that focused on more smaller-stakes assessments to better engage students with the…

Can critical analysis be carried out without the support of minimal conceptual structuring in the field in question? The results of a research survey of beginning teachers are briefly discussed. Interviews on radiocarbon dating illustrate what we call a "delayed critique", i.e. after a phase of critical passivity and concomitant…

The majority (67%) of degree-granting physics departments in the United States grant a bachelor's degree as their highest degree. There are 84 departments that grant astronomy bachelor's degrees. Of these departments, 39 are separate, stand-alone astronomy departments, and 45 are in departments that award both astronomy and physics degrees. The…

The aim of this study is to develop and apply a rubric to evaluate the solutions proposed for questions about electromagnetic induction belonging to university second year pre-service teachers. In this study which has pretest-posttest quasi-experimental design with control group, teaching of the topic of electromagnetic induction was applied to…

Agentic engagement, or attempts to proactively influence instruction, predicts positive classroom climate and students' motivation. As such, it is a potentially effective target for intervention, though causal evidence is limited. This investigation explored whether an agentic orientation could be cultivated through a brief, online intervention…

Due to the rapid change and development in science and technology, it has come to the fore to educate individuals with 21st-century skills. Scientific argumentation plays important role in developing 21st-century skills. Several studies were conducted on argumentation in science education and laboratory, however, the limited study examined…

The history and philosophy of science (HPS) plays a special role in education. An elective HPS course on the philosophy of scientific experimentation for young scientists and graduate students of natural science is presented. The course bears a pragmatic character, and its main aims include the development of critical thinking (CT),…

Sound is one of the most commonly used physical phenomena that most of us use without considering its nature. Moreover, students often face difficulties in understanding acoustic phenomena, the most frequent one of which is the substance-based view of sound instead of a process of pressure and density differences. The current study introduces…

Measuring the 3D position at any time of a given object in real-time automatically and well documented to understand a physical phenomenon is essential. Exploring a stereo camera in developing 3D images is very intriguing since a 3D image perception generated by a stereo image may be reprojected back to generate a 3D object position at a specific…
