    “人工智能與教育”專家系列筆談之六

    人工智能助力教師教學創新

    發布時間:2019-08-03 作者:郭紹青 來源:中國教育報

    人工智能作為關鍵共性與顛覆性技術,正在對產業結構、生活環境等產生影響。人工智能進入教育領域,推動了智能學習系統、虛實融合學習環境、智能教育助理等智能系統和工具的開發與供給,智能教育環境建設已現端倪。實現機器智能與人類(教師)智慧相融合指向學習者的高級思維發展、創新能力培養,啟迪學習者智慧的新教育,培養復合型、創新型、戰略型、智慧型的人才,能夠對人工智能與人類智慧相融合從事社會工作的勞動者的智慧教育進行廣泛討論。教師作為人工智能融入教育的直接利益相關者,具備利用人工智能學習系統和工具開展教學的知識與技能,提升人工智能技術素養顯得十分重要。當前人工智能教育產品正在快速進入學校與課堂,為教師利用人工智能技術實現教學創新提供了支撐。

        智能診斷助力教師優化課堂教學。適應性學習系統、手寫板、智能閱卷等系統進入學校,為教師提供了對學生個體、小組、班級等隨堂數據和課外數據采集與分析的手段,教師利用數據分析結果,精準定位學生個性學習問題與班級的普遍問題,找準學生個性與共性薄弱點、聚集學生學習障礙點,改進教學策略與方法,進行分層、分類教學,提升教師在課堂教學中解決學生學習問題的針對性與教學效率。

        學習分析技術助力教師開展規模個性化教學。《中國教育現代化2035》提出“走班制、選課制等教學組織模式……利用現代技術加快推動人才培養模式改革,實現規模化教育與個性化培養的有機結合”的要求,具備大數據學習分析功能的網絡學習空間的應用,對學生學習的精準畫像,使教師在精準掌握學情的基礎上,能夠有效組織翻轉課堂、小組合作學習、探究學習等學習活動。同時,學習分析技術正在推動網絡學習空間中以個性化發展為核心的動態學習組織的發展,并引發實體學校動態走班制度的建立,實體學校與網絡學習空間相融合的動態學習組織發展,將使教師實施規模個性化教學成為現實。

        課堂智能分析助力教師精準教研。集自然語言處理、計算機視覺、生物特征識別等技術的課堂教學智能分析系統的應用,實現了對課堂教學過程數據的伴隨性采集,匯聚課堂教學多維數據的智能分析能夠形成更加精準的教師課堂教學行為的可視化分析結果。跨校際、跨區域的教研活動,利用課堂教學智能分析系統的分析報告,結合教研員與優秀教師評價分析,為研修教師提供精準服務,指導、組織、協助研修教師進行深度學習,對提升研修效果與效率具有顯著作用。

        智能學習系統助力教師提升教學質量。目前相對成熟的智能學習系統主要集中在智能語言學習方面。英語流利說、英語趣配音等一批利用自然語言處理技術開發的智能語言學習系統進入了教育領域,教師利用英語智能學習系統能夠支持學生的聽說訓練,特別是在面向農村教學點的專遞課堂中的應用,能夠彌補教師自身的能力缺陷。同時利用自然語言處理技術與AR/VR相融合開發的藏、維雙語智能學習系統將為學生提供多通道的人機交互,提升國家通用語言的學習質量。

        人工智能助力教師家校協同。人工智能技術在家校協同教育中的應用,正在改變家校教育分離、難以形成合力與協同監管的現狀。一些縣區在推動人工智能教育應用過程中,利用人工智能技術助力家校協同教育,利用智能校徽與體溫和人臉采集攝像機,無感采集學生體溫、運動量、行動軌跡等數據,協助教師與家長掌握學生健康狀況、安全信息、運動強度。要求學生閱讀課外書籍,并在每天規定時間內利用紙筆系統寫出讀后感,教師能夠及時進行點評,對培養學生的學習習慣、擴寬知識面等發揮了積極作用。
