教師講解示范,學(xué)生仔細(xì)觀察,提出動作的重點(diǎn)與難點(diǎn)。組織措施:學(xué)生由原來的準(zhǔn)備活動隊(duì)形如(圖1),前一二排向左轉(zhuǎn)帶入籃球場的一個(gè)半場,后兩排向右轉(zhuǎn)帶入籃球場的另外半場分組練習(xí)如(圖4),教師巡場指導(dǎo),組別間可以進(jìn)行上籃成功率的比賽。?語言提示進(jìn)行腰部、腿部放松練習(xí),及調(diào)整呼吸放松。?組織措施:學(xué)生成四列橫隊(duì)廣播體操散開,全體學(xué)生面向教師,隊(duì)形如(圖2)。(2)騰空高度不夠,右腿不能快速上抬。自喊口令“一、二、投”,同時(shí)做出右腳、左腳連續(xù)向前跨兩步后投籃的動作。八、場地器材:場地:籃球場 器材:跳高架2個(gè)、橡皮筋末端系一小球2個(gè)、籃球若干(根據(jù)學(xué)生人數(shù)而定)、秒表一個(gè)、紙筆。練習(xí)密度為60%左右,學(xué)生獲得適宜的運(yùn)動負(fù)荷,有效的增強(qiáng)體質(zhì),并有利于知識技能的提高,以及養(yǎng)成良好的鍛煉習(xí)慣。目標(biāo):培養(yǎng)學(xué)生的遵守規(guī)則、團(tuán)隊(duì)合作能力增強(qiáng)集體榮譽(yù)感及提高學(xué)生對籃球的興趣。備 2頭上振臂和體前屈,(四)見習(xí)生認(rèn)真聽教師講解,并協(xié)助教師上好5 3體轉(zhuǎn)運(yùn)動,課。重點(diǎn):起跳時(shí),踏跳腿迅速踏 跳發(fā)力,重心向上提,動作舒展,重心高,騰空時(shí)間長。正法 ? 教師示范動作,前兩排同學(xué)蹲下學(xué)生基 30 們仔細(xì)觀察。圖4 二,教學(xué)安排: 要求:練習(xí)時(shí),注意動作細(xì)節(jié),維持好課堂紀(jì)? 教師講解與示范,學(xué)生注意聽講并仔律,小組間可進(jìn)行比賽。下面我就從教材分析、教學(xué)目標(biāo)、教學(xué)重點(diǎn)和難點(diǎn)、學(xué)情分析、教學(xué)方法、教學(xué)過程設(shè)計(jì)等方面進(jìn)行說課。如果說投籃是一把大刀的話,那么低手上籃就是小李飛刀,快、準(zhǔn)、穩(wěn)!所以學(xué)好它,可以提高學(xué)生進(jìn)攻手段的多樣性和全面性。發(fā)展目標(biāo):發(fā)展學(xué)生的靈敏、柔韌、協(xié)調(diào)等身體素質(zhì)。五、教學(xué)方法考慮到學(xué)生心理和生理的特點(diǎn),我將采用問答法、講解法、示范法、分解練習(xí)法以及完整練習(xí)法進(jìn)行教學(xué),從而調(diào)動學(xué)生的積極性和主動性,培養(yǎng)學(xué)生的觀察和思維能力,更好的完成教學(xué)目標(biāo)。u 要求學(xué)生注意力集中,動作做到位而且要協(xié)調(diào)舒展。u 在隊(duì)形上采用兩邊兩列,教師站中間,便于學(xué)生觀察,然后組織學(xué)生練習(xí)。(5)各小組集中展示,學(xué)生討論教師做出評價(jià)。216。(2)小結(jié)本課u 運(yùn)用鼓勵(lì)的語言肯定學(xué)生在本節(jié)課取得的成績和存在的問題,布置課后練習(xí),并提出對下節(jié)課的要求。以學(xué)生身體練習(xí)為主要手段,以學(xué)生的“健康第一”為指導(dǎo)思想,課堂上注重學(xué)生運(yùn)動技術(shù)的教學(xué),充分調(diào)動大部分學(xué)生的主動參與性,發(fā)展學(xué)生自主探索能力,培養(yǎng)學(xué)生合作能力。開展利于活動可以發(fā)展學(xué)生的奔跑能力、快速反應(yīng)能力和身體的靈敏性和彈跳力。大部分學(xué)生喜愛籃球運(yùn)動。2.技能目標(biāo):發(fā)展學(xué)生的上下肢、腰、腹肌的力量和動作協(xié)調(diào)能力。六、教學(xué)過程本節(jié)課教學(xué)過程分為:開始部;基本部分;結(jié)束部分;三個(gè)階段。6.教師巡回各組進(jìn)行指導(dǎo),與學(xué)生交流。七、場地器材合理美觀的場地安排和組織是完成教學(xué)設(shè)計(jì)的前提保證,為此,我做了如下安排:籃球場一塊,籃球11只。說是“三步上籃”其實(shí)只有兩步而已:1先讓練習(xí)拍球、運(yùn)球,最好是練到盲拍的程度,就是不看球可以帶球熟練的跑。右腳落地時(shí)候把球拿在手里,左腳落地右膝蓋上抬的時(shí)候把球向上拋,作投籃狀,投籃應(yīng)該會吧?4從三分線外開始,帶球沿邊線往籃板的方向跑。注意兩點(diǎn):1上面我介紹的是右撇子的方法,如果你是左撇子,那方向相反。以學(xué)生身體練習(xí)為主要手段,以學(xué)生的“健康第一”為指導(dǎo)思想,課堂上注重學(xué)生運(yùn)動技術(shù)的教學(xué),充分調(diào)動大部分學(xué)生的主動參與性,發(fā)展學(xué)生自主探索能力,培養(yǎng)學(xué)生小組合作能力。二、教學(xué)目標(biāo)依據(jù)教材和教學(xué)對象的分析,我確定本課的教學(xué)目標(biāo)為:,能在課堂教學(xué)活動中,相互合作,自主探究學(xué)習(xí)。:提高學(xué)生的控球能力和三步上籃的節(jié)奏。(一)激發(fā)興趣,熱身導(dǎo)入上課常規(guī):體育委員整隊(duì),師生問好,宣布本課內(nèi)容、教學(xué)目標(biāo),并強(qiáng)調(diào)安全意識,這樣安排是為了盡快進(jìn)入課堂狀態(tài),杜絕運(yùn)動損傷的發(fā)生。三步上籃練習(xí)①自由結(jié)組練習(xí)三步上籃,體會三步上籃技術(shù),培養(yǎng)學(xué)生觀察能力,讓學(xué)生學(xué)會學(xué)習(xí),學(xué)會自我評價(jià),為今后的自主探究學(xué)習(xí),創(chuàng)造學(xué)習(xí)培養(yǎng)能力。適當(dāng)?shù)膮⑴c各組練習(xí),給學(xué)生做出優(yōu)美、準(zhǔn)確的示范,加深師生的感情,使學(xué)生在輕松愉快的氣氛中自學(xué)總結(jié),針對一些出現(xiàn)的問題,教師小范圍上點(diǎn)拔,糾正
