43、 網(wǎng)絡(luò)學(xué)習(xí) 教學(xué)反思 在英語(yǔ)活動(dòng)中,要注重語(yǔ)言知識(shí)與語(yǔ)言技能的結(jié)合,采用多種教學(xué)媒體、多種教學(xué)方法,引導(dǎo)孩子們養(yǎng)成良好的發(fā)音、理解英語(yǔ)、運(yùn)用英語(yǔ)的習(xí)慣。在這堂課中,我覺(jué)得比較成功的教學(xué)活動(dòng)有以下幾點(diǎn):一、利用本課內(nèi)容相關(guān)的電腦動(dòng)畫并伴隨歌曲,孩子們邊唱邊舞,調(diào)動(dòng)了興趣,溶入英語(yǔ)課堂氛圍。二、電腦動(dòng)畫中用精美畫面,豐富的色彩展示課文內(nèi)容并有美語(yǔ)純正發(fā)音,引導(dǎo)孩子們跟說(shuō),完善了學(xué)生的語(yǔ)音、語(yǔ)調(diào)等語(yǔ)言技能。三、利用課件設(shè)謎,理解對(duì)話,并運(yùn)用對(duì)話,舉一反三。四、學(xué)生自已操作電腦游戲,自主學(xué)習(xí),激發(fā)了學(xué)生的學(xué)習(xí)熱情,增強(qiáng)了自信心,發(fā)揮自已的潛能。五、表?yè)P(yáng)、鼓勵(lì)、競(jìng)賽相結(jié)合,學(xué)生語(yǔ)言實(shí)踐積極性高,語(yǔ)言訓(xùn)練充足。 由于小學(xué)英語(yǔ)具有靈活性與針對(duì)性,因此這堂課我覺(jué)得還需改進(jìn)的是,根據(jù)孩子們的英語(yǔ)能力差距,設(shè)計(jì)不同層次的活動(dòng),使各層次的學(xué)生都能得到相應(yīng)的發(fā)展,都能獲得成就感。采用開(kāi)放的、互動(dòng)的模式,給予學(xué)生更多的交流與實(shí)踐機(jī)會(huì)。在今后的課堂教學(xué)中,我將以人為本,時(shí)刻洞察孩子們的興趣與愛(ài)好,改進(jìn)教學(xué)方法,力求教學(xué)策略與學(xué)習(xí)策略相互促進(jìn),發(fā)掘孩子們的潛力,保持孩子們的學(xué)習(xí)熱情。
