基于建构主义理论对计算机辅助外语教学的启示,以外语词汇教学为例,具体分析了集影视、图片与字形于一身的多形式词汇教学,运用构词法扩展词汇,利用比较法帮助学生区分近义词,使用扩展法帮助学生建立语义网,运用图表来展示词与词之间关系以及充分展示词汇的文化意义等多种形式的外语词汇教学形式,以证明二者结合的有益性和必要性。
Based on the implications of constructivism for computer-assisted instruction in foreign languages, taking foreign language lexis as an example, this paper analyzes the multi-form lexical teaching of video, image and glyph in detail. It uses word formation to expand vocabulary, and uses comparison to help students to distinguish synonyms. Extensions help students to establish semantic networks, use charts to show the relationship between words and words and fully demonstrate the cultural significance of vocabulary and other forms of foreign language vocabulary teaching to prove the combination of the two benefits and necessity.
