“…For example, the work [5] presents the results of developing a piece of software consisting of two modules: UA-LAB (Universal Analog LABoratory) and CV-LAB (Capacitance & Voltage LABoratory). The first module is designed for voltage measurements and the second for laboratory testing with high sensitivity and accuracy of voltage and capacitance measurements.…”

Currently, we are witnessing the active introduction of modern digital technologies in the field of education. One of the main reasons for this was the transition to distance learning due to the global COVID-19 pandemic. More and more virtual labs, virtual textbooks, as well as educational platforms that allow students to acquire the necessary skills and abilities remotely using the Internet, are being used in the educational process. The most promising educational platform is an interactive mobile learning platform. It has several advantages, among which one can especially single out the convenience of learning due to its interactivity and organization of the studied material. The application of augmented and virtual reality allows for increasing the effectiveness of classes. These technologies provide another level of interaction and material perception by students. However, VR and its high level of immersion require special equipment and more actions from the user while AR is cheaper and more affordable, but still interactive and has great visual aids. The aim of the paper is to demonstrate how augmented reality can be used for radio engineering disciplines on the example of an interactive mobile platform. This article discusses the process of developing a mobile platform that allows studying the material of radio engineering courses using augmented reality technology. The work also contains the results of a survey conducted among the students who used it as a part of their class activities. In addition, sections of the article contain a description of the project development process, its structure, international experience, and the conclusions.

“…While many first-year undergraduates experience learning about light and matter, these often occur in a fragmentary manner. , Typically in high school, the systematic study of light occurs in physics courses and is unrelated to matter, with minimal coverage beyond electron configurations in chemistry classes. Also, high school students are unlikely to use spectrophotometers because of cost and time constraints, − and for the students in our study group, this situation was made worse by the pandemic and online learning. There may also be issues with existing curricula standards.…”

A key part of the practice of chemistry is the analysis of chemical composition, including through gravimetric analysis and spectrophotometry. However, the complexity of doing multiple calculations to obtain analytical evidence, such as that required to determine an empirical formula, presents a challenge if such analytical methods are to be understood by students and if they support meaningful learning about other chemical concepts and methods. In this study, we investigate student use of spectrophotometry and gravimetric analysis to determine the number of water molecules in hydrates of copper(II) salts, a method previously described by Barlag and Nyasulu. Using phenomenography to analyze students’ reports through the lens of meaningful learning, we identified four distinct perceptions and, within them, information on how students make sense of the complex analytical steps involved in the experiment. We identify how meaningful learning is present where students recognized that spectrophotometry was based on light–matter interactions (cognitive), was faster and more accurate (psychomotor), and allowed students to express confidence in the process and their results (affective). However, it is also the case that meaningful learning was compromised where students had trouble conceptualizing spectrophotometry, saw it as a set of disconnected steps, and saw absorbance as a computer-generated value and not a property of the solution. This led to the perception that gravimetric analysis provided a more direct and understandable technique. We discuss the implications of these findings for chemistry education research (CER) and curriculum development in the undergraduate teaching lab.
