Abstract
In order for future teachers to effectively utilize IoT technology in the classroom, it is essential for them to develop IT competencies. This includes having the knowledge and skills to integrate IoT devices and platforms into their teaching practices, as well as the ability to analyze and interpret data collected from these devices. The formation of IT competencies using IoT for futureteachers is crucial in preparing them to navigate the ever-evolving landscape of technology in education. Teachers must be able to perceive technology as an important element of their present and future lives and recognize its essential role in the development of their countries. Furthermore, teachers need to understand that the way students learn in the 21st century is different from traditional methods, and they must adapt their teaching practices to accommodate technology and harness its potential in enhancing student learning. One of the challenges in the field of education in the era of the industrial revolution 4 is the use of internet technology in learning, which is part of 21st century learning. This study made an effort to give a broad overview ofcurrent trends and unresolved issues in using IoT-based teaching and learning and its applications in diverse fields.The investigation performs a bibliometric analysis to focus on peer-reviewed research articles published in well-known publications databases. The findings of this study should also act as a strong incentive for universities and colleges to use IoT-based teaching and learning technology for improved academic achievement.
