Background: Physics textbooks are a learning resource for students to acquire knowledge and information. The findings of previous studies on physics textbooks analysis have mostly focused on representations of gender, the nature of science, and scientific literacy. This study, therefore, extends the critical content analysis of physics textbooks…

This study addresses the measurement of high school students' epistemic knowledge associated with scientific experimentation (EKSE) which concerns "how" scientific experimentation generates knowledge and "why" that knowledge is justified. Based on philosophical, educational standards, and literature analyses, an EKSE construct…

Several properties of Earth's magnetic field (field vectors, time dependence) are measured in various locations using a smartphone/tablet magnetic sensor. To enable a proper use of the magnetic sensor as a classroom tool, the exact location of the sensor in the device and its resolution must be identified in a first step. Then, students may…

This study investigates the challenge faced by eighth-grade students at Southern State Middle School in grasping abstract concepts within the domains of physical science, physics, and chemistry. This difficulty is manifested in their poor performance on summative assessments. A comprehensive analysis of state-provided data, in conjunction with…

Laboratory experimentation providing students with hands-on experiences can greatly enhance the teaching and learning of physics. However, traditional hands-on laboratories are very expensive, limiting the possibilities for practical activities. In addition, limited time for laboratory practices prevents teachers and students from conducting…

What follows is a description of the procedure for and results of a simple experiment on the formation of impact craters designed for the laboratory portions of lower mathematical-level general education science courses such as conceptual physics or descriptive astronomy. The experiment provides necessary experience with data collection and…

Experiments with Lecher Lines have always been important in the physics curriculum for demonstrating standing waves and the important concept that waves can be guided as well as being emitted into space. A system operating at low power (less than 10 mW) and in the frequency range 300 MHz to 800MHz is described and the wavelength of the radiation…

This paper discusses the importance of one of the most crucial elements in science and technology education: the development of the individual capacity to cope with new problems. Also, discuss the importance of being aware of the existence of "formative objectives" and "tacit knowledge". In the planning of a course, taking into…

In experimental physics, lab notebooks play an essential role in the research process. For all of the ubiquity of lab notebooks, little formal attention has been paid to addressing what is considered "best practice" for scientific documentation and how researchers come to learn these practices in experimental physics. Using interviews…

Labs have long been considered an important component of physics education. However, while there has been progress in transforming physics education in physics lecture classes to improve student learning, less progress has been made in introductory physics labs. At the same time, the physics community has come to recognize that there is a need to…

We present a study of the maximum stress supported by elastics bands of nitrile as a function of the natural length and the load time. The maximum tension of rupture and the corresponding variation in length were found by measuring the elongation of an elastic band when a mass is suspended from its free end until it reaches the breaking point. The…

We designed a physics laboratory exercise around pulse oximetry, a noninvasive medical technique used to assess a patient's blood oxygen saturation. An alternative to a traditional optics and light lab, this exercise teaches the principles of light absorption, spectroscopy, and the properties of light, while simultaneously studying a common…

Research has shown that project-based learning promotes student interest in science and improves understanding of scientific content. Fostering student motivation is particularly important in accelerated science and technology programmes for talented students, which are often demanding and time-consuming. Current texts provide little guidance on…

Integration of technology, social learning and scientific models offers pedagogical opportunities for science education. A particularly interesting area is thermal science, where students often struggle with abstract concepts, such as heat. In taking on this conceptual obstacle, we explore how hand-held infrared (IR) visualization technology can…

The physics curriculum is usually defined by content but this does not provide students with an authentic experience of the subject. An alternative is that physics is defined more as a way of thinking and this idea is explored in terms of the purposes of physics education, assessment and the relationship of the subject with other disciplines. A…
