The teaching means have been easier with the help of computers and many universities are building smart classes equipped with computers and electronic board. Pictures and information are now presented easily and clearly using high technology means. For example, I remember when I was in high school that I had difficulties in understanding 3 dimensional vectors in math classes since teachers used to draw them in a 2 dimensional elementary black board by bad French chalks. While nowadays in colleges, professors use high quality drawing software such as 3 D Max to present such vectors on computers screen and projectors. And so these vectors are no longer complicated and they are easily absorbed.
When using internet which is of course one application of computers, searching and getting information are no easier and faster. For example, I was assigned a research paper about preserving Alaska wilderness and when I started my research in the national library I was shocked because I did not find any book talking about the topic. Later, a friend of mine advised me to use the internet for my research. And doing so, I found hundreds of webpages each of them is specialized in each different aspects of the topic.
