8B Unit 1 Past and presentPeriod 4 Grammar（1）Title(課題)GrammarType(課型)New（新授課）Period(課時(shí))4Supportingtheories(理論支撐)A. 波蘭尼的知識(shí)分類觀：隱性知識(shí)是存在于個(gè)人頭腦中的、難以正規(guī)化、難以溝通的知識(shí)。所以，我們知道的多于我們能夠言說(shuō)的。顯性知識(shí)和隱性知識(shí)構(gòu)成了一座冰山，前者浮出海面，后者在下面托起整個(gè)冰山。從根本意義上說(shuō)，只有借助隱性知識(shí)的力量，人類所有的顯性知識(shí)才得以發(fā)生和發(fā)展，人類的知識(shí)創(chuàng)新才有根基。B多元智能理論：多元情境化教學(xué)策略是激發(fā)學(xué)生學(xué)習(xí)興趣的有效辦法。運(yùn)用多元情境化教學(xué)策略，將英語(yǔ)課的導(dǎo)入多樣化，使教學(xué)內(nèi)容很快就調(diào)動(dòng)起學(xué)生的多種智能，實(shí)現(xiàn)了“把學(xué)習(xí)時(shí)間和學(xué)習(xí)過(guò)程還給學(xué)生”，讓學(xué)生在探索和合作中獲得知識(shí)，促進(jìn)英語(yǔ)學(xué)習(xí)。有效地實(shí)現(xiàn)了事半功倍的效果。實(shí)踐證明多元情境化教學(xué)策略在初中英語(yǔ)教學(xué)中的應(yīng)用，必然調(diào)動(dòng)學(xué)生多種智能活動(dòng)，學(xué)生在參與的過(guò)程中，體會(huì)到了學(xué)習(xí)英語(yǔ)的快樂(lè)，從而拉近了英語(yǔ)與學(xué)生的距離，激發(fā)了學(xué)生學(xué)習(xí)英語(yǔ)的興趣，培養(yǎng)了學(xué)生自主學(xué)習(xí)的能力。有效地提高了課堂教學(xué)的成效。Aims & Demands(教學(xué)目標(biāo))Key points & Difficulties(教學(xué)重、難點(diǎn))1.
