The correct answer to this open question is the following.
The challenges to education that the current knowledge explosion pose are the following.
First, the challenge to really understand concepts instead of just barely know something more. There are millions of pages on the internet. Students just have to click on the internet searching for an answer, and that's it. They have their answer. But one thing is to get an answer and another completely different thing is to use critical thinking t understand a concept, and idea; its context, causes, definitions, alternatives, and so on.
Another challenge is the use of technology as a means of distraction and entertainment, instead of learning. Technology is a great tool, but it does not substitute the teacher in the classroom.  A "hybrid" model that combines the two could be the answer in the future. 
Another challenge could be the capacity of technology to reach every single corner of the country in developed countries and undeveloped nations. Not everybody has the money to permanently access technology devices and internet resources as a way to "attend school online." Poverty, lack of resources, geography, and other circumstances often hinder many students to attend school online. 
 
        
             
        
        
        
Answer:Self-enhance 
Explanation:John Dewey recognized that people engage in self-enhancement when they distort things about themselves because they want to create a positive image that will make them look like they more lovable and capable. This is motivated by the fact that one wants to create this perception of being big and better.
 
Self enhancement has nothing to do with improving so that you can be better but it is all about creating an image that will make you look like you are more competent and capable individual more than one is in reality.
