A smartphone is a powerful learning aid in the hands of a large section of students around the world. The camera of the phone can be used for several learning purposes apart from its obvious purpose of photographing. If the focal length of the lens of the camera can be determined, several experiments in optics can be performed with it. In some…

Practical experiments enhance students' understanding of basic concepts and promote deep learning experiences in chemistry. The smartphone application of Lab4Chemistry was utilized to replace colorimeters with smartphone camera sensors. Low-cost and readily available materials, including anthocyanin (fresh red cabbage) and common kitchen…

Intelligent personal assistants (IPAs) carry massive potential in enhancing students' performance through individualized dynamic scaffolding strategy. Despite IPAs being increasingly recognized among educationists, little is known about their application in the development of students' scientific inquiry skills, particularly in physics. This study…

Field trips provide real-world learning opportunities in biology education as they promote knowledge about nature among other things. As biodiversity is declining knowledge of species is important for understanding and appreciating the natural world and its implications. Many field guides are digitally available, but differences from traditional…

The main aims of the present research were to: (1) describe the scientific outputs indexed in the Scopus and Web of Science databases, from now on WoS, regarding the use of comic books as didactic resources in the teaching-learning of the sciences, and; (2) establish the conceptual structure of scientific output regarding the use of comic books as…

There is a growing need for chemistry students to be able to handle and manipulate large datasets and analyze them in an efficient and accessible way. This creates the need to develop course materials that introduce these topics early in the undergraduate curriculum. To address this growing need, this activity introduced RStudio to students…

We propose a laboratory experiment on the quantitative study of the normal dispersion of light. A triangular isosceles prism made of flint glass TF3 is used as the object of study, and we describe a simple and affordable device for observing and photographing the dispersion spectrum on a smartphone. A possibility of the quantitative investigation…

A smartphone magnetometer is used to record the magnetic field of a freely falling point dipole magnet. The recorded magnetic field vs. time data are analyzed in accordance with the spatial dependence of the magnetic field to calculate the acceleration due to gravity g. The experiment gives local g to be 9.79 ± 1.9% m/s[superscript 2].

Studying the dynamics of beams is considered an indispensable field for mechanical and civil engineering students. This paper describes, in detail, the use of smartphones in educational practical works to determine and examine the dynamic characteristics of beams subjected to free vibration. Where the smartphone is equipped with a mobile…

Preparing elementary-aged children to practice data science literacies is important and understudied. Our research investigates how data science curricula might be effectively designed and integrated into elementary classroom instruction. We use narrative case study methodology, focusing on a single case detailing a second-grade teacher's approach…

In physics lessons at secondary school and experimental physics courses at universities, the magnetic field inside a current-carrying solenoid is considered quantitatively. The corresponding equations and theories are supported by measuring the magnetic flux density inside the solenoid with a Hall probe. It has already been shown that smartphones…

In this laboratory experiment, students modify a series of surfaces and explore the effects of varying surface chemistry and texture on wettability by different probe liquids. Students begin by building a simple contact angle goniometer utilizing their mobile phone cameras. Next, they contrast the wettability of planar glass substrates…

This study explores the potential of QR code technology in enhancing preservice science teachers' understanding of astronomy topics and their views on the Nature of Science (NOS). Using QR codes, the study focused on teaching complex concepts like the Kuiper Belt, dwarf planets, and Pluto's reclassification, while fostering an explicit and…

Fluorescence analysis is an important technology, which can obtain the concentration of target analytes through comparing the fluorescence intensity change of a fluorescent sensor. Generally, the fluorescence intensity is measured by a fluorometer. However, many undergraduates have no chance to operate such an expensive instrument. Besides, the…

Herein, we developed a mobile augmented reality (AR) application that can recognize chemical bonding by arranging markers on which atoms are augmented, in accordance with the specific characteristics of actual chemical bonding. From an educational affordance perspective, the development targets for AR application were selected to recognize…
