?師生再見(jiàn)。?組織措施:學(xué)生成四列橫隊(duì)廣播體操散開(kāi)，全體學(xué)生面向教師，隊(duì)形如(圖2)。?要求:動(dòng)作舒緩進(jìn)行。?教師總結(jié)本節(jié)課教學(xué)，并布置課外作業(yè)。七、教學(xué)中可能出現(xiàn)的問(wèn)題及解決預(yù)防方法: 1(可能出現(xiàn)的問(wèn)題:(1)上籃步數(shù)不清楚，腳下動(dòng)作不協(xié)調(diào)。(2)騰空高度不夠，右腿不能快速上抬。(3)騰空投籃時(shí)，動(dòng)作僵硬不協(xié)調(diào)，雙手拋球，手臂伸不直。(4)個(gè)別學(xué)生運(yùn)球時(shí)球的落點(diǎn)不對(duì)，或太前或太后，導(dǎo)致起步不順。預(yù)防方法:(1)徒手腳步練習(xí)站定，左腳在前，右腳在后，適當(dāng)屈膝，雙手做持球狀。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(dòng)作。(2)讓學(xué)生扶墻或欄桿，快速屈膝抬右腿，放下，落地后重復(fù)數(shù)次，注意練習(xí)時(shí)的彈性和節(jié)奏感，這樣既能增強(qiáng)下肢力量又能提高學(xué)生的動(dòng)作質(zhì)量。(3)做原地單手投籃練習(xí):站在籃圈右下方，雙手持球，兩腿為屈跳起后，在重心達(dá)到最高點(diǎn)處，開(kāi)始由右手托球的下方，伸臂撥腕，可以將球直接投入籃筐，或打板進(jìn)筐，逐人練習(xí)，讓每個(gè)學(xué)生都體會(huì)單手肩上投籃的感覺(jué)。(4)對(duì)于運(yùn)球基本功不過(guò)關(guān)的學(xué)生先進(jìn)性運(yùn)球的行進(jìn)間練習(xí)，再過(guò)渡到運(yùn)球的行進(jìn)間上籃練習(xí)。八、場(chǎng)地器材:場(chǎng)地:籃球場(chǎng) 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。九、效果預(yù)計(jì): 1(預(yù)計(jì)70%以上學(xué)生能初步掌握本課所學(xué)的行進(jìn)間單手肩上投籃技術(shù)。2(預(yù)計(jì)本課學(xué)生的運(yùn)動(dòng)強(qiáng)度為中等，最高心率165次/分左右，平均心率130次/分左右，練習(xí)密度為60%左右。測(cè)量心率方法:隨機(jī)抽3至5個(gè)學(xué)生進(jìn)行心率測(cè)試，開(kāi)始熱身部分測(cè)安靜時(shí)的心率，準(zhǔn)備活動(dòng)熱身結(jié)束時(shí)測(cè)熱身心率，學(xué)習(xí)提高部分學(xué)生進(jìn)行游戲比賽時(shí)測(cè)最高心率，整理恢復(fù)部分做完完全放松整理運(yùn)動(dòng)和調(diào)整呼吸后測(cè)恢復(fù)狀態(tài)的心率。練習(xí)密度為60%左右，學(xué)生獲得適宜的運(yùn)動(dòng)負(fù)荷，有效的增強(qiáng)體質(zhì)，并有利于知識(shí)技能的提高，以及養(yǎng)成良好的鍛煉習(xí)慣。運(yùn)動(dòng)
