Catalogization and systematic analysis of immersive applications for general secondary education

Digital solutions are integrated into education at all levels, becoming integral. Among modern developments, a special place is occupied by immersive services, the implementation of which contributes to increasing student motivation and engagement, improving the assimilation of educational material, the formation of practical skills through simulations, etc. Since the market for immersive services has significantly enriched in recent years and continues to fill dynamically, it is often difficult, and sometimes impossible, for users, including teachers, to choose an appropriate service among hundreds of existing solutions. In this regard, the problem of developing a database of immersive services arises - cataloging services with a balanced filtering system that would consider the needs of teachers and facilitate their search for appropriate solutions. Recent systematic analyses indicate that immersive technologies in secondary education span diverse platforms including virtual reality (VR), augmented reality (AR), mixed reality (MR), and tele-immersive environments, each offering unique pedagogical affordances for spatial visualization, simulation, and collaborative learning. Meta-analyses demonstrate significant improvements in student engagement (effect size g=0.596-0.603) and learning outcomes, particularly in STEM subjects. The purpose of this article is to substantiate the structure of the catalog of immersive services with the aim of their pedagogically appropriate systematization for general secondary education. We analyzed various catalogs and aggregators of immersive services, comparing their features, filtering systems, advantages, and disadvantages. A survey of 16 experts with experience in scientific research and practical use of immersive services in education was conducted to determine filtering criteria. The developed “Catalog of Immersive Services” includes filtering by category (AR, VR, XR, 360-degree video, 3D-modelling), educational level (grades 1-4, 5-9, 10-11(12)), subject area, interface language, terms of use, and platform compatibility. The catalog serves as a practical resource for teachers to identify and implement appropriate immersive technologies in their educational practice.
