Electronic devices are becoming increasingly popular in today's modern classrooms. Two significant devices are interactive whiteboards (IWBs) and tablets, which are making a great impact on teaching and learning. An IWB is a large screen connected to a computer. The teacher and students use special pens or touch to control the board and write on it. They can also show videos and do interactive activities on the board. This helps capture students' attention and make the lesson more dynamic. Meanwhile, a tablet, such as an iPad or an Android device, is a handheld computer which students can use for various purposes. For example, they can access e-books, use educational apps, and collaborate with their classmates. School tablets are portable and provide access to a vast resource of educational contents. However, both IWBs and tablets have drawbacks. They are costly, so not all schools can afford them. Besides, there are potential technical issues, and much time and effort are needed to train teachers and students to use them effectively. While challenges exist, these electronic devices help create a more interactive and engaging learning environment in today's classrooms. Therefore, schools should consider using them appropriately.
