在新媒体背景下,思政课教学中充斥着大量的信息"噪声"干扰,不可避免却又直接影响着教学效果的提升,而"中国近现代史纲要"课程"以史育人"的内容特点更易遭受信息"噪声"的干扰,因此有必要引入信息论中"噪声"干扰难以消除时的纠错码应对机制,有效降低新媒体"噪声"对它的影响.利用重塑"纠错码"防范功能、维护"纠错码"纠正反馈功能、革新"纠错码"建设功能等措施辩证发力,可以将新媒体给"中国近现代史纲要"课程带来"噪声"干扰的"变量"转化为提升信息传输实效的"增量",为提升课程育人实效提供全新思路.
Under the background of new media,the teaching of ideological and political courses is filled with a lot of information"noise"interference,which inevitably but directly affects the improvement of teaching effect.The content feature of"educating people with history"in the course"Outline of Modern and Modern Chinese History"is more susceptible to the interference of information"noise".Therefore,it is necessary to introduce the response mechanism of error-correcting code under this condition in which it is difficult to eliminate the interference of information"noise",so as to effectively reduce the effect of new media"noise"on it.The use of measures such as reshaping the"error-correcting code"prevention function,maintenance and correction feedback function,and innovation and construction function can dialectically transform the"variable"that the new media brings"noise"interference to the course of"Outline of Modern and Modern Chinese History"into an"increment"to improve the effec-tiveness of information transmission,and provide a new way to improve the effectiveness of curriculum education.
