During the SARS-2-COVID pandemic our institution sought to continue the teaching and learning of experimental laboratories by designing, assembling, and delivering a microscale chemistry kit to the students' homes. Thanks to this approach students were able to perform [approximately]25 experiments during each one of the Fall 2020 and Spring 2021…

This study aims to implement an exemplary instructional design-based ICT integration to allow students to acquire both course achievement and knowledge society skills. The research used the case study method. The participants consist of 30 students, who attend the course of Science and Technology at the 7th grade level in a state school, along…

A fluorometer is a device that measures the spectroscopic properties of fluorescent materials, and fluorometry is used widely in chemistry research settings to characterize fluorescent samples. One of the obstacles faced by undergraduate programs looking to implement fluorometer-based experiments into their laboratory curriculum is the high cost…

This study presents an experimental method that illustrates and quantifies the Doppler-effect phenomenon. Two stages of the experimental process were carried out. First, a simplified ripple tank was used to depict the Doppler effect, and the whole experiment was recorded by a digital camera. Second, video analyses of the recorded experiment were…

In this study, we made a simple electronic electroscope called a 'polarity detector' which can determine the type of electric charge on any objects. We used the polarity detector in some student experiments in the physics laboratory. For example, when we applied a plastic rod to a piece of fabric made of wool, we could easily determine that the…

Electroscopes have been widely used in physics education for several reasons, such as their simplicity, sensitivity and visual appeal, showing macroscopic phenomena related to the microscopic world. Although they are capable of highly accurate measurements, the procedures involved in these measurements encounter some obstacles when performed with…

Virtual Learning Environments (VLEs) are becoming commonplace in Higher Education. Amongst the latest VLE developments is the design and use of Virtual Microscopes (VMs) that allow for viewing and manipulation of online images by multiple students. Although students are found to be generally satisfied with the use of VMs, it is yet not known what…

Over the past decade the Accreditation Board for Engineering and Technology, Inc. (ABET) has changed the general chemistry requirements to include a single introductory course for most engineering majors. There is a focus on outcomes that equip students with the ability to pass the Fundamentals of Engineering (FE) Exam and to work in…

This article explores the possibilities of a cheap one-dollar microscope, the Foldscope, for enhancing out-of-school science education. Developed by Manu Prakash and Jim Cybulski from Stanford University, these origami-type paper microscopes make it possible to provide all students with their own microscopes, due to the low cost. This provides…

This study aimed to determine the cognitive structures of preservice primary school teachers for basic biology concepts using Word Association Test (WAT). The study group consists of 50 preservice teachers studying in a university in Western Black Sea Region in Turkey. Four separate cut-off points were determined and analysed. Organ, living…

Background: An increasing number of educational institutions are incorporating virtual reality (VR) applications in the instruction methodology for their laboratory science courses. However, there is debate about the use of the physical vs. the virtual lab as according to research the former offers a positive research-training environment, whereas…

At constant current (I) the forward bias potential (V) of a "pn" junction diode may be considered to vary linearly with temperature (t) within a temperature range. Based on this property we have constructed diode thermometer using germanium (Ge) and silicon (Si) diodes. The experimental "V-t" data at constant forward current…

Traditional laboratory courses involve students following detailed weekly experimental procedures, culminating in either a laboratory report or handout at the end of each experiment. While this setup teaches basic laboratory skills, it usually does not encourage students to think critically or independently. Therefore, many laboratory instructors…

Here, we propose the use of magnetic levitation (MagLev) device, as a simple, cheap, and portable experimental technique to measure the density of diamagnetic materials in laboratory settings. We highlight the basics of a standard MagLev system for measuring the density of unknown diamagnetic materials/objects using permanent magnets, paramagnetic…

The fungi kingdom is among the important topics of biology, and students can develop misunderstandings and misconceptions about this subject. This study aims to determine misunderstandings and misconceptions of 5th-grade students about fungi. The participants of the study consisted of 22 (12 girls, 10 boys) fifth graders of an elementary school in…
