教育信息化背景下,微課已成為一種新型在線教學資源呈現(xiàn)方式,是教和學的重要輔助資源,外語微課研究熱潮也隨之興起。本文以兩屆中國外語微課大賽16個一等獎作品為研究對象,采用多模態(tài)分析法、問卷調(diào)查、訪談與語料庫詞頻法探究優(yōu)秀外語微課的特征。首先,本文以張德祿（2009）提出的多模態(tài)話語分析理論框架為依據(jù),統(tǒng)計分析16個獲獎作品中出現(xiàn)的模態(tài)以及模態(tài)間的關系,以期發(fā)現(xiàn)各種符號資源是如何構建話語意義的;其次,分別運用問卷和訪談兩種方法調(diào)查外語教師眼中優(yōu)秀外語微課應具備的特征;最后,運用語料庫詞頻分析法研究大賽評審專家眼中優(yōu)秀外語微課應具備的特征。研究發(fā)現(xiàn),優(yōu)質(zhì)外語微課的多模態(tài)分布情況是聽覺模態(tài)占主導,且聽覺模態(tài)和視覺模態(tài)的關系中互補關系占主導;外語教師和評審專家認為優(yōu)質(zhì)外語微課應具備三方面的特征:1)選題。優(yōu)秀外語微課的選題有趣、獨特、范圍小且基于學生的學習需求和興趣;2)教學。教學目標實用且基于學生的接受能力;教學過程完整,結構清晰、富有邏輯;內(nèi)容豐富、合理、完整、新穎、簡潔;講解語言發(fā)音清晰、標準、流暢、語速適中;3)視頻制作。視頻流暢、生動、穩(wěn)定、清晰、色彩和諧、沒有噪音。本研究可為外語微課...
