高中人工智能课程项目案例资源设计与开发

随着新版《普通高中信息技术课程标准(2017年版)》的发布,案例教学资源尤其是具有情境性、复杂性、综合性、实践性等特点的项目案例教学资源的建设成了一项亟须解决的任务。面对目前项目案例资源严重不足的现状,文章在相关研究基础上,基于大数据时代背景下人工智能应用的视角,提出了基于大数据的人工智能应用开发框架,阐述了该开发框架所包含的网络爬虫应用开发和基于大数据的人工智能应用开发流程的设计。基于该开发框架并结合新版《普通高中信息技术课程标准(2017年版)》中的“人工智能初步”模块要求,构建了高中信息技术课程的人工智能应用设计框架。基于该设计框架,使用Python语言开发了有声小说、教育故事文本分析、人脸检测与人脸识别三个人工智能应用项目案例。这些项目案例融合了大数据、人工智能应用的典型特征,具有较好的迁移性,不但可以在高中信息技术课程中的“人工智能初步”模块以及其他模块中使用,其设计框架也为基于学科核心素养的高中信息技术课程教学的落地提供了一种解决思路。

Design and Development of Project Case Resources for AI Course in Senior High School

With the release of the new version of Information Technology Curriculum Standards for Senior High Schools(2017 edition), the construction of case teaching resources, especially project case teaching resources with scenarios, complexity, comprehensiveness and practicality, has become an urgent task to be solved. Faced with the serious shortage of project case resources at present, based on relevant researches and from the perspective of AI application in the era of big data, this paper puts forward the framework of AI application development based on big data, and expounds its application development of web crawler and the design of AI application development based on big data. Based on the development framework and the requirements of the "Preliminary Artificial Intelligence" module in the new version of Information Technology Curriculum Standards for Senior High Schools(2017 edition), this paper constructs the design framework of AI application for high school information technology curriculum. Based on this design framework, three AI application cases of audio fiction, text analysis of educational stories, face detection and face recognition are developed by using Python language. Those project cases integrate the typical characteristics of big data and AI application, and have good mobility. Not only can they be used in the "preliminary AI" module and other modules of high school information technology curriculum, but also their design framework provides a solution to the implementation of high school information technology curriculum teaching based on subject core literacy.
