在现代文教学中,要实现最优效果,一个语文教师,除了确定教学目标、选择教学内容外,更主要的是善于选择教学媒体。根据信息论的原理,“媒体”是指运载、携带信息来往于信息源与接受者之间的任何东西,而“教学媒体”是以教会别人为目的传递信息的任何东西。从传播理论可以知道,一种教学内容信息可以采用多种多样的符号去呈现。如:文学符号、语言符号、静止图像符号、活动图像符号,以及其他一切目视符号和音响符号,而不同的信息符号对教学内容信息都有不同的呈现功能。现代文教学,主要是通过文字符号、语言符号的呈现,使学生感知到信息源的存在,教师借助对信息源的分析,使学生明白其中所蕴藏
In modern literary teaching, to achieve optimal results, a language teacher, in addition to determining teaching objectives and selecting teaching content, is more important in selecting teaching media. According to the theory of information theory, “media” refers to anything that carries and carries information between the source and the recipient, and “teaching media” is anything that transmits information for the purpose of teaching others. From the theory of communication, we can know that a kind of teaching content information can be represented by a variety of symbols. Such as: literary symbols, language symbols, still image symbols, moving image symbols, and all other visual symbols and acoustic symbols, and different information symbols have different presentation functions on teaching content information. Modern text teaching is mainly through the presentation of word symbols and language symbols, which enables students to perceive the existence of information sources. Teachers make use of the analysis of information sources to make students understand what they contain.
