传统的数学教学主要靠文字、符号等平面静止状态来表达教学内容。教师讲得累,学生学得也不轻松,有些学生在学习中感到单调、枯燥,而导致注意力分散,课堂气氛不活跃。而计算机辅助教学(CAI),则是把文字、图形、图像、动画、声音等多种媒体结合在一起,把静止的文字、符号变为动态的图形、图像等等。从信息论的角度看,刺激了学生的各个感官,使学 Traditional mathematics teaching mainly rely on the text, symbols and other static plane to express the teaching content. Talking about tired teachers, students learn is not easy, some students feel monotonous in learning, boring, which led to distraction, the classroom atmosphere is not active. Computer aided instruction (CAI) combines texts, graphics, images, animations, sounds and other media to convert still text and symbols into dynamic graphics and images. From the perspective of information theory, stimulate the senses of students to make learning
