In recent years, nanoscience and nanotechnology have been drawing enormous attention due to the numerous applications of nanomaterials. In an attempt to nurture interest towards these areas in young minds and to develop the next generation of environmentally conscious scientists and engineers, this new laboratory module focuses on the green and…

This work deals with the experimental demonstration of coupled oscillators using simple tools in the form of mechanical coupled pendulums, magnetically coupled elastic strings or electromagnetic oscillators. For the evaluation of results the data logger Lab Quest Vernier and video analysis in the Tracker program were used. In the first part of…

Understanding chemistry requires the interplay of several modes of representations which can be observed in the translational skills of students. This paper investigated the extent of the translational skills of students exposed to conventional lecture method (CLM) and the integrated macro-micro-symbolic approach (IMMSA). Individual interviews…

Data collection is a fundamental skill in science education, one that students generally practice in a controlled setting using equipment only available in the classroom laboratory. However, using smartphones with their built-in sensors and often free apps, many fundamental experiments can be performed outside the laboratory. Taking advantage of…

The present study uses the intuitive rules theory as a framework to examine whether some of the difficulties in dealing with errors and uncertainties observed among students in the university physics laboratory can stem from their use of intuitive rules. The study also examines the relationship between the use of intuitive rules and laboratory…

Young's double-slit experiment is one of the most historically significant works in physics, and one that is easily done in an introductory physics class. It is also an excellent example of an investigation that allows us to infer the nature of phenomena beyond direct observation. Unfortunately, perhaps because of this, it is often also an…

Previous work covers building a tower from a stack of homogeneous rectangular plates, each with a maximum shift in displacement. We suggest using plates shaped as curvilinear triangles bounded by segments of power-law functions. The masses of the plates and the position of their center of mass are calculated and measured experimentally after…

Lens imaging is a classic topic in physics education. To guide students from their holistic viewpoint to the scientists' analytic viewpoint, an image-based approach to lens imaging has recently been proposed. To study the effect of the image-based approach on undergraduate students' ideas, teaching experiments are performed and evaluated using…

Measuring voltage-current and voltage-power curves of a photovoltaic module is a nice experiment for high school and undergraduate students. In labs where real sunlight is not available this experiment requires a solar simulator. A prototype of a simulator using LED lamps has been manufactured and tested, and a comparison with classical halogen…

During the Jurassic period (201 million to 145 million years ago), termites up to 15 mm long consumed and recycled vegetation and feces. Since then, termites have evolved into some 3,000 identified species, have colonized every continent except Antarctica, and are major contributors to nutrient cycling and vertebrate food webs (Shaw 2014).…

We describe a simple experiment about sliding friction of an object moving with non-constant speed along an inclined plane. This experiment can be used to study the entire dynamical process of force and motion in various ways, depending on the mathematical level of the students. We discuss how video measurement and analysis, and mathematical…

The iPhone 6 introduced a new feature of recording video in Slo-Mo mode at 240 fps (4.17 ms interval). This great capability when integrated with video analysis freeware such as Tracker offers in-depth exploration for physical phenomena such as collisions that occur in a very short duration of time. This article discusses one such usage in…

[This paper is part of the Focused Collection on Curriculum Development: Theory into Design.] This paper discusses the theoretical framework and curriculum materials that form the basis of the Investigative Science Learning Environment (ISLE) approach to learning and teaching physics. ISLE, as a philosophical approach to learning, has two core…

Today, individuals with special needs who are reported to increase each day are receiving education with their peers in general classes and are subjected to inclusive practices according to the developments in the field of special education and legal regulations. However, it is also reported that there are problems with special education in many…

An upper-division organic chemistry laboratory experiment exploring fluorescent sensing over two laboratory periods and part of a third is described. Two functionally distinct pH-responsive sensors are prepared through a dehydrative three-component coupling reaction. During the abbreviated (<1 h) first laboratory period, students set up…
