When you say computer, you imagine its hardware, the tangible parts. But this computer would hardly be useful without software.
The software is the system that tells what the computer should do. There are two kinds of software, the systems software which is the operating system bundled inside all computers, and the applications software which contains the system that commands the particular task or solves a particular problem.
The application software may be a custom software made for specific tasks or a commercial software packaged for personal computers.
Instructional software may be found in software shops or even in the internet. In using instructional software, the teacher should decide on the best computer-based instructional (CBI) materials for the school resource collection. The internet may provide too much information which could be completely useless. The teacher should then evaluate these CBI materials using sound pedagogical principles. The materials should provide accurate, coherent and logical information.
