高分范文: The Use of PPT in Class

With the advance of educational technology, the use of PowerPoint(PPT) is becoming increasingly popular in class. However, it is a controversial issue that has raised wide public concern. In my view, we should hold a cautious attitude toward the widely used PPT in class.

On the one hand, a well-designed PPT definitely enhances teaching efficiency in that all the knowledge has been prepared beforehand. What’s more, many delicately designed PPTs are quite attractive to students. But on the other hand, we have to admit potential problems exist with the overuse of PPT in class. For example, an excessively informative class would be overloaded for the learners, resulting in students’ distraction from the key points. Moreover, teachers’ heavy reliance on PPT is another concern. It is said that many teachers don’t know how to teach without PPTs.

As a result, teachers are supposed to take both the teaching efficiency and students’ leaning outcome into consideration, and make a good balance between them. After all, all the use of technology, including PPT, should respect the educational principles and students’ real needs.
