Dear College Dean
It is my understanding that this college has received a large donation to be used to enhance (improve) the quality of life for students: expand the bookstore or add puters to the puter lab. It is the tradition of this school to promote education and to be in the vanguard of new technology. That is why I strongly argue in favor of the addition of more puters to the puter lab.
Although expanding the campus bookstore to include CDs, gifts, and a snack bar will give a nicer look to the college, we have to think about a greater goal and a more practical way to enhance the quality of life for students. What do we want for our students and our college? Do we want our college to be known as a place with a great bookstore where you can find CDs and gifts, or as a place where the students can explore and research in their field using the best tools provided by technology? In addition, there are already several snack bars on campus, and there are music stores nearby, so students do not depend on the college bookstore for these things.
We live in a highly technological world and puters play an increasingly important role in how we live. As a learning institution, this college has the responsibility to offer its students the best technology to help them prepare for their future. Many students will be expected to be familiar with the latest software and other tools when they go on to work or to graduate school.
While they are in college, students find they are expected to use puters. Many professors expect students to use puters to do homework or to plete projects. Students are asked to create PowerPoint presentations and use spreadsheets and database programs, as well as to research many topics on the Internet. Since students are peting for good grades, those who have limited access to puters are at a great disadvantage. Furthermore, being able to do projects using the puter enhances the process of learning, giving students the opportunity to find information that without a puter would be much more difficult to find.
If there are more puters, students will also be able to plete their work more efficiently. No more will they have to wait in line, paper and disk in hand, while scanning the room for an empty chair and puter. No longer will they have to sit and wait while an outdated puter struggles to follow their mands. Having more new and faster puters available will enable students to finish their work more quickly.
The more puters are used in society the more colleges will depend on them as a tool of teaching and learning. Making puters more available to students facilitates their learning process by making the process easier, more interesting, more engaging, and in the process enhancing their quality of life
