项目驱动教学在网络爬虫课程中的应用研究

Research on the Application of Project-driven Instruction in the Course of Web Crawler

网络爬虫课程是大数据科学与技术专业的核心课程。针对传统课堂教学的学生参与度不高、学生学习效率较低等问题,该文将项目驱动教学法应用于网络爬虫课程的教学实践。通过选择学生普遍关心的热门话题,合理设置项目难度及核心知识分布,能够不断激励、引导学生自主学习兴趣,掌握自主学习方法并最终提升学习效率。最终的测试结果表明,通过项目驱动教学,学生对数据获取、数据清洗及数据可视化等核心知识点的掌握程度有较大幅度地提升。

Web Crawler is the core course of big data science and technology.In order to overcome the problems of low student participation and low learning efficiency in traditional classroom teaching,a project driven teaching method is applied to the teaching practice of web crawler course in this paper.By selecting popular topics that students are generally interested in,reasonably setting the difficulty of the project and reasonably assigning the distribution of core knowledge,the awareness of autonomous learning can be enhanced for improving their learning efficiency.The final test results show that the students'mastery of core knowledge points such as data acquisition,data cleaning and data visualization has been greatly improved by the web crawler project designed in this paper.
