英語教案八年上

1、仁愛版八年級上冊Unit 3 Topic 1  Section C教案  （1）學(xué)情分析     八年級學(xué)生的心理特征:自主、獨(dú)立，具有較強(qiáng)的求知欲和探索精神，大部分學(xué)生熱愛思考、敢于表達(dá)。然而，也有部分學(xué)生存在不自信，羞于表現(xiàn)等思想顧慮。 知識基礎(chǔ)：通過前兩課的學(xué)習(xí)，學(xué)生已有一定的基礎(chǔ)和理解力，掌握了一些關(guān)于討論興趣愛好的表達(dá)。 認(rèn)知心理：大部分學(xué)生勤奮好學(xué)，但語言表達(dá)能力不強(qiáng)，有待培養(yǎng)的是擴(kuò)展能力 （2）教材分析     

2、    Section C是Section A、B的延續(xù)。Section C又是Section D的前奏。是本單元四個部分中最重要的一環(huán)。 本課時旨在創(chuàng)造一個輕松、愉快的學(xué)習(xí)、交流環(huán)境，通過聽、說、讀、寫來培養(yǎng)學(xué)生綜合運(yùn)用這些知識的能力。以“授之以魚，莫如授之以漁”的思想，讓學(xué)生去親身體驗(yàn)，互動交流，創(chuàng)造性地去學(xué)習(xí)。并讓學(xué)生通過有限的課堂實(shí)踐活動能準(zhǔn)確地用英語來表達(dá)所學(xué)知識。為了更好地在40分鐘內(nèi)最有效地實(shí)現(xiàn)教學(xué)目標(biāo)，本人從學(xué)生實(shí)際出發(fā)，對教材進(jìn)行了一些調(diào)整。   （3）教學(xué)安排 &#
