Exploration of Teaching Reform of Data Collection and Web Crawler Course Based on PDCA Cycle

Abstract

The course of Data Collection and Web Crawler is highly practical and students are generally interested in learning it. However, the traditional teacher-centered teaching model focuses on knowledge transfer, which cannot meet the social demand for big data talents. PDCA (Plan-Do-Check-Act) cycle is the ideological basis of total quality management, which accords with the inherent law of teaching quality management. With "students" as the core and based on PDCA cycle, this paper carries out reform design from four processes of Plan, Do, Check and Act. The four stages of PDCA cycle correspond to the design, implementation, evaluation and reflection of teaching. The “Plan” part includes the design of teaching objectives and the design of teaching content. The teaching objectives are divided into knowledge objectives, ability objectives and quality objectives, while the design of teaching content can be summarized as addition, subtraction, adjustment and integration. The “Do” part mainly adopts a variety of teaching methods, such as the combination of theory and experiment, the combination of online and offline, the combination of group and individual reports. The “Check” part adopts a variety of evaluation methods, including examination, operation and reporting, to comprehensively evaluate students' knowledge, abilities and qualities. The “Act” part is mainly about standardizing successful methods, documenting existing problems to avoid repeat offenses, and transferring unresolved problems to the next cycle. Under the new teaching mode, the teaching is student-centered, giving full play to students' subjective initiative, and improving their ability and quality while mastering knowledge.
