【摘要】 根据《局域网与城域网》实验的目的与特点,提出了3L实验方法,将该课程的实验分成了3个层次:立足课程内容、巩固课堂教学成果的理论验证型实验;启发式引导、深入探索技术本质的启发引导型实验;以及自主式设计、提高综合应用能力的开放设计型实验。在此基础上,文中对每个层次的实验方法进行了详细介绍,并举例进行了说明。实施效果表明,将3L实验方法应用于《局域网与城域网》实验,起到了良好的作用,达到了预期的目的。更多还原

【Abstract】 According to the objective and characteristic,this paper proposes 3L experiment method for Local and Metropolitan Area Network,and sets the experiments to three levels.The first level is verifying experiments,which aimsat consolidting teaching results in classroom.The second level is inspiring experiments,researching the nature of technology deeply.The third level is designing experiments,in which the students design and finish the experiments mainly by themselves.The application results show the 3L experiment method has obvious effects in Local and Metropolitan Area Network.更多还原
