简介:随着网络市场急速发展,智能产品市场扩张,韩国教育的发展趋势也发生变化。教育市场的需求使人们关注教育和游戏相结合的教育游戏(edutainment),并结合多媒体教育和智能产品研制开发相关教育软件,取得了很大的成果。韩国汉字教育也受到教育环境变化的影响,向虚拟化、智能化的方向发展。本文通过对网上教学与移动学习方面的汉字教学资源如网上汉字教学、汉字游戏、汉字学习应用程序的分析,考察目前韩国网络环境下的汉字教学情况。同时以汉字学习应用程序为例,讨论适用于汉字移动学习的汉字教学法。目前韩国汉字学习应用程序只限于提示汉字的读音及意义,多采用问答(Quiz)形式测试已学过的字。本文在汉字学理论及汉字教学理论的基础上,探讨具有层次性及多元化的适用于汉字移动学习的汉字教学法。
