基于OBE教育理念的《路基路面工程》试验课教学设计——以挖坑灌砂法测定压实度为例

Experimental Course Design of Subgrade and Pavement Engineering Based on OBE——Taking the Method of Digging and Filling Sand to Measure the Degree of Compaction as an Example

《路基路面工程》是土木工程专业的一门专业核心课程,具有理论知识和工程实践紧密结合的特点。该文从OBE教育理念出发,选取《路基路面工程》试验环节中的挖坑灌砂法测定压实度这一质量评定内容,以现场质量评定要求为导向,运用加拿大NAIT的四步教学模式,探索实验内容的教学改革,通过整合试验内容、改进设计、强化过程性考核内容和标准,提高了学生的工程能力,为学生解决工程中的复杂工程问题奠定了良好的基础。

Subgrade and pavement engineering is a professional core course of civil engineering,which has the characteristics of close combination of theoretical knowledge and engineering practice.Based on the OBE education concept,this paper selects the quality evaluation content of compaction measurement by digging hole and sand filling method in the test link of subgrade and pavement engineering,takes the on-site quality evaluation requirements as the guidance,the four step teaching mode of NAIT is used to explore the teaching reform of experimental content.By integrating the experimental content,improving the design and strengthening the content and standard of process assessment,the engineering ability of students is improved,and a good foundation is laid for students to solve complex engineering problems in engineering.
