Abstract: CDIO engineering education idea is introduced firstly. The existing issues in experiment teaching of fundamentals of electronic technology are analyzed secondly. After that, based on CDIO teaching mode, experiment teaching method reform on fundamentals of electronic technology is performed, which includes reform conditions and how to implement CDIO during a reform. At last,a reform practice result on fundamentals of electronic technology teaching is reported, which shows the students’ motivation of learning electronic technology is effectively excited and engineering practice ability of applying electronic technology is improved.
