3、總結(jié)(這部分要5分鐘)學(xué)生在教師的提示和問題的引導(dǎo)下，完成對本節(jié)課的知識的歸納和小結(jié)。利用簡煉、清晰的語言，再一次的突出本節(jié)課的重點(diǎn)，起到畫龍點(diǎn)睛的作用，培養(yǎng)了學(xué)生的表達(dá)能力。4、鞏固練習(xí)(這部分要10分鐘)用大屏幕投影把題目投影在屏幕上，讓學(xué)生思考，然后回答。這部分安排10分鐘的時(shí)間，讓學(xué)生思考完成具有針對性的練習(xí)，進(jìn)行知識鞏固和教學(xué)效果反饋，及時(shí)糾正錯(cuò)誤的理解和片面的認(rèn)識。5、板書設(shè)計(jì)在板書中,我根據(jù)板書的“規(guī)范、工整和美觀”的要求，結(jié)合所學(xué)的內(nèi)容，設(shè)計(jì)了如圖所示的板書。在其中，注重了重、難點(diǎn)的突出，使學(xué)生對知識的結(jié)構(gòu)、層次、重點(diǎn)、難點(diǎn)一目了然，便于記憶和理解。四、效果分析對于反射的判斷，學(xué)生仍有可能出現(xiàn)錯(cuò)誤，如刺激坐骨神經(jīng)肌肉的收縮，教師應(yīng)強(qiáng)調(diào)沒有完整的反射弧結(jié)構(gòu)參與的不是反射。
