Abstract: Aiming at solving the “4 ‘fixed’ and 1 ‘simple’” problem, namely the fixed titles, fixed process models, fixed knowledge points, fixed technology applications in engineering basic experimental education and the regulation of judging everything simply by presentations in the assessment, and aiming to improve the engineering ability, based on the whole life cycle of software, we constructed the “five-order collaboration” full-life-cycle experimental teaching mode, based on which we designed the “dual elements, quantity and quality combined” mode of evaluation that combines process and result evaluations. This teaching mode converted the mode that teacher designs fixed experiments to that students design experiments themselves, which could develop students’ ability of researching, creative and initiative learning. Through the validation of OBE achievement degree and the normal distribution of score results, the learning effect was proved to be improved effectively.
