# Intelligent Educational Environments: Recent Trends, Modeling, and Applications
## 3 Overall Picture Regarding the Intelligent Education  
Over the past ten years (2014-2024), the topic of intelligent education has been very much researched and discussed, as evidenced by the large number of published scientific articles. The query \"intelligent AND education\" was submitted on 14 March 2025 to the scientific database Scopus. It aims to outline the trends in the research on intelligent education. The query is broad but has the advantage of giving an overall picture of the studies and pointing out trending topics. The goal is to explore the most popular research topics instead of making a comprehensive literature review. The query is conducted on the titles, abstracts, and author keywords of the publications. The Scopus scientific database has a relatively wide interdisciplinary scope and indexes various research publications worldwide, including conference proceedings, journal articles, and books. That is the main reason the authors conducted the bibliometric query there. The bibliometric study gives valuable insights into current subjects of interest in intelligent education. It is not a thorough literature review on intelligent education but rather a snapshot of the research interest in the explored area. The returned result contains 15,718 documents. Among these, there could be some out-of-scope publications; however, the presumption is that mentioning the words \"intelligent AND education\" in the title, abstract, and author keywords provides a solid basis to show the research topics in the area. The extracted bibliometric information of these publications is ordered by relevance and analyzed using RStudio 2024.12.1 and the bibliometrixobiliboship application. The annual growth rate is 10.68%, noticing a trend of a continuously increasing number of publications, as in 2014, there were 941; in 2020, there were 1486 (about 1.58 times more than in 2014); and in 2024, there were 2596 (about 2.76 times more than in 2014) (Figure 1). This can be explained by the development of intelligent technologies and their impact on education. Researchers observe how these technologies can contribute to enhancing learning and teaching and improve the quality of education in general. Table 1 includes overall information about the articles indexed in Scopus, and it is seen that they are published in 4993 different sources (journals, conference proceedings, and books) in diverse subject areas from computer science, engineering, and social sciences through mathematics, decision science, medicine, business, management, and accounting. The different problems and contexts with which intelligent education is associated can be judged not only by the diversity of the subject matters of the sources but also by the large number of different keywords and references used by the authors. Articles prepared by a team of authors are about 14 times more than those with a single author. The percentage of participation by foreign authors (at least one of the authors must be from another country) is not high (12.71%), which indicates that collaborative studies are most often between authors from the same country. \begin{table}
