In the last decade, Science, Technology, Engineering, and Mathematics (STEM) education has rapidly evolved and increasingly makes use of innovative technologies. This paper aims to explore and analyze the research on integrating the Internet of Things (IoT) within STEM education and outline key aspects and emerging trends. A complete picture of the recent ten years is gained by gathering bibliometric data from the Scopus and Web of Science scientific databases. Two search queries combining IoT, STEM education, and security were submitted to extract relevant publications and obtain insight into the explored area. The manual content analysis of the study results and publications outlines several key roles of IoT in implementing STEM educational practices, which are conceptualized to reflect user viewpoints. Widespread IoT applications in STEM at different educational levels are discussed and summarized. The special focus on security aspects showed that they are underrepresented, evidenced by the small number of publications related to IoT in STEM education. The importance of including topics aimed at designing and implementing secure IoT applications in STEM-oriented curricula and courses is also discussed.

This paper aims to summarize recent trends in the field of intelligent education and build on the research findings to propose a conceptual model of an intelligent educational environment (IEE) along with possible applications. A bibliometric analysis explores the recent trends to obtain insights into the current research directions. The concept of an IEE is introduced and correlated to other popular concepts in the educational field. Relevant user requirements for the IEE are defined and discussed. They serve as the basis for creating the conceptual model as a UML class diagram. The proposed model gives an overall picture of the relationships among the essential elements of the IEE and provides insights into its future development. Two possible applications are outlined: personalized teaching and learning and the assessment process. Any particular application of the model to build an IEE must consider all specific user requirements and add relevant details. The proposed conceptual model can be used to enhance the teaching–learning process and improve learners’ performance.

The paper presents an innovative usage of the modular data hiding methods [5], [6] for the prevention of phishing attempts. The main idea is to use the multimedia content of corporate portals for the enhancement of their security. This is achieved by a combination of modular data hiding, cloud-based software services and suitable add-ons on the sides of the corporate portals and their end users. Among the additional benefits are the adaptability of the modular data hiding to different security needs and the full backward compatibility with already existing security solutions.
