This research will be carried out at the basic physics laboratory of the physics education study program, Muhammadiyah University of Makassar. The long-term goal of this research is to produce a prototype model of basic physics practicum based on the virtual android observatory to facilitate the ICT literacy skills of prospective physics teachers.…

Several suggestions for the use of Mobile Phone (MP) sensors in science teaching are found in the literature, and most of them focus on proposing physics experiments that can be conducted with the aid of the sensors that commonly exist in smartphones. The proposed experiments rely on the Bring Your Own Devices (BYOD) approach, that is, students…

Enzyme purification, characterization, and identification are some of the best ways to introduce undergraduate students to many aspects of biochemistry, particularly as part of project-based learning (PBL). These kinds of multi-step laboratory experiments not only help students to better understand basic biochemistry concepts but also serve to…

The development of a QR code as a barcode label contains information about the item to which it is attached. However, information on QR code development in engineering science laboratories is still limited. The aim of this research is to design the QR code lab manual for laboratory work in polytechnics engineering science course. In addition, the…

Contribution: This article presents a teaching experiment platform for an undergraduate laboratory program designed to fulfill the needs of control engineering classroom experiment teaching. The teaching experiment platform is a cost-effective teaching tool that can be promoted on a large scale in colleges and universities. The teaching experiment…

This experiment introduces undergraduate organic chemistry students to analysis and interpretation of Fourier transform infrared (FTIR) spectra through characterization of postconsumer plastics. Students use FTIR spectra to identify and differentiate the common recyclable polymer resins #1-6: polyethylene terephthalate (PETE), polyethylene (HDPE…

Archimedes' principle is one of the foundation subjects in physics. Normally the principle is exemplified by reference to floating boats. However, Archimedes' principle also applies to objects embedded in waterlogged ground, which can lead to the surprising result of an object weighing several tons being lifted. A practical example is presented of…

The difference between students' ideas and scientific conceptions, is called misconceptions. Physics learning needs to be designed by teachers to eradicate misconceptions. This paper provides a review of 72 international journal articles on diagnosis methods, causes, and ways of remediating misconceptions that have been published between…

Experimentation is widely accepted as being central to science education. However, anxiety about experimentation often prevents its use. While a considerable number of studies on anxiety related to laboratory experimentation have been conducted, studies on in-class experimentation is limited. In the research study reported on here we explored the…

Students sometimes learn about a model of the "scientific method" that is linear and clear cut. While this approach may have pedagogical advantages, it does not reflect how science is often done in practice. The Experimental Modeling Framework (EMF) describes the complex and iterative process of experimentation in the domain of physics,…

Similar to how stealth materials were developed to reduce the radar wave energy returning from an aircraft, here we explore a low-cost laboratory demonstration that uses similar principles to prevent detection of an object by an ultrasonic sensor. This demonstration setup can be used as a starting point to encourage students to explore the surface…

We discuss the limits of the equation of the period of a simple pendulum, T[subscript s] = 2[pi][square root]l/g, frequently used in high-school and university classrooms to measure the acceleration of gravity. We evaluate the relative error in determining the acceleration of gravity with this simple equation instead of a more realistic one,…

Virtual Chemistry Laboratories (VCLs) are used as an alternative to the physical laboratories, where users can enhance their performance for hands-on chemistry experiments. However, cognitive load and other issues make the VCLs impractical. The issue of cognitive load arises due to the complexity of the environment by displaying a number of…

The falling rod paradox, i.e. the fact that the tip of an almost horizontal rod falls with an acceleration 'higher than g', when the other end is hinged or supported, is a popular physics demonstration. It can be visualized by placing e.g. a coin on the tip of the rod and fixing a cup next to the coin. When the rod is released the free-falling…

This Article comes from a series of 2 h instrumental analysis laboratory experiments developed in response to social distancing requirements established because of the coronavirus pandemic (COVID). The experiments provided rich data-analysis opportunities that taught students the chemical principles that underpin instrumental techniques, yet made…
