Big data acquisition and cleaning is the first part of big data processing, mainly to solve the problem of data sources and dirty data cleaning, to provide qualified data samples for the subsequent big data analysis and application. The course of Big data acquisition and cleaning is the first professional core course of data science and big data technology. The course has many difficult knowledge points, involves many tools and software, is closely integrated with the application, and requires the high practical ability of students, so it is impossible to achieve the teaching purpose by the traditional teaching method. In this paper, based on the OBE concept, the teaching content, teaching methods, and course assessment methods are reformed. From the point of view of the students’ learning effect and evaluation results, the course reform has achieved the desired effect.
