“跨媒介阅读与交流”任务群研究存在“理论和实践研究结合不紧密”“相关概念界定不清”等问题，且缺乏可供参考的官方配套教材和教学模式。鉴于“跨媒介阅读与交流”任务群在新课标背景下语文教学中具有提高学生媒介素养、培养学生语文核心素养、引导学生树立正确价值观等重要作用，本研究在对该任务群相关文献进行综述的基础上，对“跨媒介阅读与交流”任务群的相关概念进行厘定和辨析，并结合任务群要求与高中语文教学的实际情况设计了涵盖资源、教师、学生、评价在内的实施策略分析维度，以之为标准，对该任务群的相关典型教学案例进行分析和评判，总结出“精挑细选资源，优化开发内容”“终身学习发展，统筹规划教学”“落实学生本位，发挥主体作用” “多元主体评价，兼顾过程终结”等可供参考的实施策略。

There are some problems in the research of "cross-media reading and communication" task group, such as "the combination of theory and practice research is not close", "the definition of relevant concepts is not clear", and there is a lack of official supporting textbooks and teaching models for reference. Given that the task group of "cross-media reading and communication" plays an important role in Chinese teaching under the background of the new curriculum standard, such as improving students' media literacy, cultivating students' Chinese core literacy, and guiding students to establish correct values, this study defines and analyzes the relevant concepts of the task group on the basis of a review of relevant literature of the task group. Combined with the requirements of the task group and the actual situation of Chinese teaching in high school, this paper designs the implementation strategy analysis dimension including resources, teachers, students and evaluation. Based on this standard, the paper analyzes and evaluates the typical teaching cases related to the task group, and concludes that "select resources carefully, optimize the development of content", "lifelong learning and development, overall planning of teaching", "implement student-centered, play the main role ", "multiple subject evaluation, taking into account the end of the process" and other implementation strategies for reference.
