Intelligent Educational Environments: Recent Trends, Modeling, and Applications
Abstract
:1. Introduction
2. Materials and Methods
- A bibliometric analysis is performed to outline the overall global picture of research focused on intelligent education. The bibliometric data are taken from the scientific database Scopus upon request for “intelligent AND education” in titles, abstracts, and authors’ keywords.
- To obtain more focused insight, a second query, “intelligent AND education AND environment,” is submitted to the Scopus database, and the results are analyzed.
- A review of implemented intelligent educational environments is conducted to clarify the technologies used, their advantages, and their benefits for individual users in the learning process: teachers and students. Based on the review, users’ requirements for IEE are derived.
- A Unified Modeling Language (UML) model is proposed that shows important elements of an intelligent educational environment, followed by their detailed description.
- Several applications are presented to practically demonstrate the functionalities of intelligent educational environments—the workflow of personalized learning and assessment.

4. Intelligent Educational Environments—Overview and Key Concepts
4.1. Intelligent Educational Environments
4.2. Intelligent Educational Systems
4.3. Intelligent Tutoring Systems
- Domain Model: It represents the learning content (usually in a machine-processable way) and provides the structure and knowledge needed to present lessons, problems, and feedback.
- Expert Model: The best possible model of expert knowledge in the domain from a scientific point of view that provides the system with correct answers, solutions, and reasoning strategies. It helps evaluate the students’ answers, i.e., the actual knowledge obtained, and identify gaps in their knowledge.
- Student Model: It represents the learner’s current knowledge, skills, psychological properties, preferences, and learning progress. It tracks individual performance and the evolution of preferences, learning styles, and behaviors.
- Tutoring Strategy/Pedagogical Module: It manages the overall teaching strategy and adaptation to the learner’s needs. It defines how the system presents and sequences the content, how feedback is delivered, and how it is used for personalization.
- Assessment and Evaluation Module: This module assesses students’ understanding of the material over time and evaluates their progress. It uses assessment tests, quizzes, or tasks to reveal whether and to what level the learner has achieved the learning objectives. Diagnostic tests, formative assessments, or summative assessments can also be included.
- User Interface: It interacts directly with users (students, teachers, or domain experts). It presents learning content, allows students to input responses, provides feedback, and ensures professional manipulation of knowledge models.
- Inference Engine: It interprets the data from the user input, the student model, and the domain model to make decisions about the next best actions (e.g., presenting problems, offering hints, adjusting difficulty). It uses logical reasoning or machine learning techniques.
- Feedback System: It provides immediate and constructive feedback based on the student’s actions and answers. Feedback can be corrective, encouraging, or suggestive (offering improvement strategies). It may also suggest hints and explanations or prompt the learner to think critically.
