摘　　要：基本运算电路是集成运放工作在线性区的典型应用,是“模拟电子技术”课程教学中的重要内容。针对基本运算电路工程性强、应用广的特点,探讨面向汽车定速巡航PID控制的递进式案例教学设计与实践,围绕教学的重点和难点知识设计1个基础案例和3个升级案例,综合运用多种信息化的教学方法手段进行教学组织实施。教学实践表明,案例式教学有助于激发学生的求知欲,提高学生的学习效果,培养学生严谨求真的科学素养和辩证思维能力。Basic analog arithmetic circuit is a typical application of the integrated operational amplifier working in the linear operation range, and it is an important content of the course of Analog Electronic Technology. Basic analog arithmetic circuit is widely used, and involves various engineering issues. Motivated by this, the progressive case-teaching design and practice of PID-based cruise control of cars is discussed, in which one basic case and three upgrade cases that cover the key points and difficulties of teaching are designed, and multiple information teaching methods of teaching organization and implementation are used. The teaching practice shows that the proposed casebased teaching method can stimulate students’ enthusiasm for knowledge, improve students’ learning outcome, and cultivate students’ rigorous attitude for science and their dialectic thinking ability.
