Resumen
The article discusses significance of computer science and educational knowledge for the creation of educational technologies. The computer provide people with a variety of experiences in simulated world that prepare one for decision-making in the real world. To make this happen, computer scientists need to envision environments they can create in which skills one needs in life can be practiced. They need to find ways to build such environments in cost-effective ways while still allowing them to be realistic. People will learn all the traditional subjects on the computer but in new ways that involve learning by doing. In the future students would not be involved in reading and writing. They will run the economy, run political campaigns, run businesses, investigate cures for diseases, practice being a doctor, and go back in time to remake historic decisions. The computer will certify those who have accomplished what they set out to accomplish in a simulation. Students will have a choice according to their will and interest.
