Classrooms
The notion of educating youngsters has remained unchanged throughout history. The classrooms we have now are significantly different from those that existed a century ago. Blackboards and chalk were used as instructional tools in the 1900s classroom.
Teachers may not have had the luxury of using these tools when they were first introduced because whiteboards and smartboards were not available then. Today’s teachers can use projectors to display presentations and videos in lectures at higher institutions.
