本文以“大土木”背景下的土木工程专业导论课——《土木工程概论》课程为例，将现代信息化教学模式和传统教学模式中的各种要素有机结合,构建了一种以SPOC平台为载体，以“问题导向、精准教学、个性学习”为主线的翻转混合教学模式框架，并进行了案例设计和教学效果评价。结果表明：翻转混合教学模式提供的精准、丰富、多元和个性化的线上资源和全过程师生互动，有效激发了学生自主学习的积极性，打破了教学活动的时空限制；课前初步内化、课中深度内化和课后全面内化，使学生对新知识的理解、掌握和应用的见解更加深入全面；引导交互、发掘学生优势潜能和培养学生个性化发展，提升了学生个人综合素质以及解决复杂工程问题的能力。

This paper takes the introduction of civil engineering course as an example under the background of “wide civil engineering“. A flipped-mixed teaching framework with SPOC platform as the carrier and "issue eliciting, precision teaching, personalized learning" as the main line is constructed, which combines with various elements of modern information and traditional teaching mode. Subsequently, the case design is carried out and the teaching effectiveness is evaluated. The results show that the flipped-mixed teaching provides accurate, rich, diversified and personalized online resources and whole-process interaction, which stimulates the initiative of students’ independent learning and?breaks the time and space limit of teaching activities. It makes students' understanding, mastering and application of new knowledge more in-depth and comprehensive through preliminary internalization before class, deep internalization in class and comprehensive internalization after class. The mixing model is benefit to the improvement the individual comprehensive quality of students and the solving?ability to complex engineering problems, by means of guiding interaction, exploring students' strengths and cultivating students' individual development.
