Nine fundamental reasons why I think technology is important in education. Hopefully, they can act as the rationale for technology plans in schools.
Reason 1. Expansion of time and place
In a typical high school a student has access to a teacher for one hour each day. That means she has access to the teacher approximately for 6% of a 16-hour waking day, and even that time is shared with 25 classmates. But she has access to the Internet 100% of the time. That's a lot better — some twenty times better. Yes, technology is no substitute for an inspiring teacher. However, on-line materials are FAR more available. As shown above, some twenty times more available.
Using the traditional textbook + classroom approach, the places where learning can occur are limited. A portable wireless computer has access to the teacher's course material and the entire Internet almost anywhere. And this is a vastly larger resource than can be practically carried on paper in a backpack.
Bottom line: information technology allows learning anywhere, anytime; not just in one particular classroom for one hour a day.
Reason 2. Depth of Understanding
Interactive simulations and illustrations can produce a much greater depth of understanding of a particular concept. When virtual manipulatives are used in a classroom setting they can go far beyond chalk and talk. Using a projector, the teacher can conduct onscreen investigations and demonstrate concepts far more easily than with just words and arm-waving. For example see Subtended Angle. Combine this class demonstration with access to the same tools over the web, and the student can reinforce the ideas by playing with the simulations themselves, any time, any where.
Reason 3. Learning vs. Teaching
Technology allows the tables to be turned. Instead of teaching (push), students can be given projects that require them to learn (pull) the necessary material themselves. Key to this is the ability to get the information they need any time anywhere, without being in the physical presence of a teacher. This project-based pull approach makes learning far more interesting for the student. I have seen firsthand how students cannot wait to get out of regular classes to go to the after-school robotics project.
Reason 4. New media for self-expression
In the old days, students could write in a notebook, and what they wrote was seen only by the teacher. Using modern technology, they can: make a PowerPoint presentation, record/edit spoken word, do digital photography, make a video, run a class newspaper, run a web based school radio or TV station, do claymation, compose digital music on a synthesizer, make a website, and/or create a blog.
Reason 5. Collaboration
A vital skill in the new digital world is the ability to work collaboratively on projects with others who may not be physically close. This can best be done using modern computer tools such as the Web, Email, instant messaging and cell phone. Rather than laboring alone on homework, students can work in small groups wherever they happen to be and at any time. They are doing this already – it can now be formalized and taught as a vital skill. Many university projects are undertaken by teams spread around the world. Your students need to be prepared for this.
Reason 6. Going Global
The worldview of the student can be expanded because of the zero cost of communicating with other people around the globe. The internet permits free video conferencing which permits interaction in real time with sister schools in other countries. From an educational viewpoint, what could be more important than understanding other cultures through direct dialog and collaboration?
Reason 7. Individual pacing and sequence
Students are, of course, all different. Information technologies can permit them to break step with the class and go at a pace and order that suits each student better. Without disrupting the class, they can repeat difficult lessons and explore what they find interesting. With time, it will become more like having a private tutor rather than being lost in a large class.
Reason 8. Weight
Three textbooks and three binders easily weigh over 25 pounds. A laptop computer weighs about 5 pounds and provides access to infinitely more material via its own storage and the Internet. A 40Gb hard drive can hold 2 million pages with illustrations; the Web is unfathomably large. Right now, students are getting back injuries lugging around a tiny subset of what they need in the form of black marks printed on slices of a substance not all that different from the papyrus used by the ancient Egyptians. And it's just static boring text.
Reason 9. Personal Productivity
Students need productivity tools for the same reasons you do. They need to write, read, communicate, organize and schedule. A student's life is not much different from that of any knowledge worker, and they need similar tools. Even if they are never used in the classroom, portable personal computers will make a student's (and teacher's) life more effective. To cash in this benefit, schools need to go paperless.
In summary, if education is about knowledge and intellectual skills, then information technology lies at the heart of it all. We have only just begun this transition. School will eventually look very different. Get ready.
