Many teachers in secondary schools and institutions of higher learning have seldom put on the blackboard. However, primary school teaching has its own characteristics. The content of primary school teaching is simple and clear, and the use of multimedia in electronic Courseware to explain, but to make the teaching content is complicated, so the primary school is still mainly in the way of teaching blackboard writing.
