网络安全课程建设是国家网络安全人才培养中的关键步骤。思政教育在网络安全课程的融入至关重要。本文以《网络信息系统安全设计与应用》课程为例,针对现有课程思政教学融入存在的问题,基于课程育人和实践育人理论,深入探索了思政教育的融入途径,提出了重塑教学目标、构造思政点、调整教学内容、构成课程思政线的顶层设计方案,“案例讨论、任务驱动、课题研究”的混合式思政教学模式,“以赛促学,思政渗透”的实验课程改革方案和多元、形成性的思政评价体系,取得较好的教学效果。Network security curriculum construction constitutes a crucial step in the cultivation of national network security professionals. The integration of ideological and political education within the network security curriculum is of paramount significance. Taking the course “Network Information System Security Design and Application” as an example, based on Curriculum education and practice education theory, aiming at the issues existing in the integration of ideological and political teaching in the current curriculum, this paper conducts an in-depth exploration of the approach to the integration of ideological and political education and proposes the top-level design scheme of reshaping teaching objectives, constructing ideological and political points, adjusting teaching content, and formulating the ideological and political thread of the curriculum. The mixed ideological and political teaching mode of “case discussion, task-driven, and subject research”, the experimental curriculum reform plan of “promoting learning through competition and infiltrating ideology and politics”, and the diversified and formative ideological and political evaluation system have achieved favorable teaching effects.
