17、達對 故事的看法和原因；能夠討論故事的開展，能夠討論愚公的做法是否 恰當并說明理由。.通過利用多媒體進行課堂教學，對信息技術加以運用，設計 多種學生參與課堂的方式，學生能夠積極思考，合作學習，探索創(chuàng)新。 通過本課教學，學生對信息技術的使用情況較好，學習效果和學習目 標的達成情況也比擬好。四、教師的支持以及信息技術的作用1、教師的支持教師在熟練掌握電子白板、PPT等信息技術工具的基礎上，創(chuàng)設 發(fā)現和解決問題的技術環(huán)境，幫助學生掌握用技術解決問題的策略， 指導和鼓勵學生積極參與課堂，促進學生主動探究，幫助學生開展分 析總結能力和閱讀理解能力。學生理解課文內容不需要像傳統(tǒng)教學中 那樣由老師滔滔不絕地

18、講解。這樣，在信息化環(huán)境下學生從傳統(tǒng)的被 動接受、機械訓練中解脫出來，主動地去探索和發(fā)現，極大調動了學 生學習的主觀能動性。2、信息技術的作用:(1)信息技術激發(fā)了學生學習興趣，奠定了教學目標實現完成 的基礎，有利于培養(yǎng)學生學習的自主性，加深了學生對知識的理解掌 握程度。拓寬了知識的形成渠道，化解了學生學習的難度，有助于培 養(yǎng)學生的創(chuàng)新能力，有利于提高課堂的教學質量。引入了人性化的評 價和激勵機制，促進了師生互動、生生互動，有利于建立良好的師生 關系。(2)信息技術有著支持學生學習的強大潛力，學生借助技術來 發(fā)現與解決問題，從而促進學生主動探究與應用知識，嘗試將問題解 決過程可視化，開展了探究學習能力和自主構建的能力。多媒體教學 軟件的運用，改善了人腦獲得知識信息的感官功能，提高了視覺與聽 覺傳遞信息的效率。在教學內容的展示上具有很強的真實感和表現 力
