一、理論基礎(chǔ)
(一)最近發(fā)展區(qū)理論對(duì)教師與教學(xué)的要求
最近發(fā)展區(qū)理論是由前蘇聯(lián)教育家維果茨基提出來(lái)的,它對(duì)導(dǎo)學(xué)案的影響主要是從教師和教學(xué)兩發(fā)面。
1.對(duì)教師在導(dǎo)學(xué)案的設(shè)計(jì)與編制上的要求
“最近發(fā)展區(qū)”理論對(duì)教學(xué)實(shí)踐提供了積極的信息,它要求教師在教學(xué)設(shè)計(jì)、教學(xué)原則、教學(xué)模式等的過(guò)程中要抓好學(xué)生的“關(guān)鍵期”。即導(dǎo)學(xué)案的設(shè)計(jì)和編制中要遵循教學(xué)設(shè)計(jì)的主體性、教學(xué)原則的適度性教學(xué)模式的主動(dòng)性。
在教學(xué)設(shè)計(jì)上,主要體現(xiàn)在教師備課上面,而備課的主要任務(wù)是首先了解學(xué)生當(dāng)前所處的階段以及他們所面臨的問(wèn)題,包括學(xué)生的性格特點(diǎn)、學(xué)習(xí)習(xí)慣、學(xué)習(xí)技能技巧以及已有的知識(shí)儲(chǔ)備,還包括學(xué)生對(duì)接受新知識(shí)的情感態(tài)度以及樂(lè)于學(xué)習(xí)的方式方法等。
2.對(duì)導(dǎo)學(xué)案教學(xué)的要求
最近發(fā)展區(qū)理論認(rèn)為傳統(tǒng)的教學(xué)處于教學(xué)的最低界限,好的教學(xué)應(yīng)該處于“教學(xué)最佳期”這個(gè)教學(xué)期是有最近發(fā)展區(qū)決定的,教學(xué)首先必須建立在學(xué)生的心理機(jī)能開(kāi)始形成的基礎(chǔ)之前。因?yàn)樗绊憙和l(fā)展的水平、速度以及智力活動(dòng)特征。
導(dǎo)學(xué)案的教學(xué)模式實(shí)際上就是要求教師在上課之前充分了解學(xué)生的已有的知識(shí)儲(chǔ)備情況,并在此基礎(chǔ)上預(yù)測(cè)可能達(dá)到的水平,為學(xué)生創(chuàng)建“最近發(fā)展區(qū)”。
(二)建構(gòu)主義理論重視“學(xué)”與“教”
建構(gòu)主義的思想來(lái)源于認(rèn)知加工學(xué)說(shuō),以及維果斯基、皮亞杰和布魯納等人的思想。
1.重視學(xué)生主體性的發(fā)揮
2.重視學(xué)生獲取知識(shí)的情境性
3.重視學(xué)習(xí)過(guò)程的自我建構(gòu)
4.重視教學(xué)目標(biāo)的多維性
建構(gòu)主義強(qiáng)調(diào)教師在教學(xué)活動(dòng)中,應(yīng)該充當(dāng)“指導(dǎo)者”的角色,為學(xué)生搭建“腳手架”,教師把任務(wù)逐漸移交給學(xué)生,最后撤去腳手架。導(dǎo)學(xué)案設(shè)計(jì)的內(nèi)容還要激發(fā)起學(xué)生的求知欲。如果枯燥無(wú)味,那么所設(shè)實(shí)施“導(dǎo)學(xué)案”便失去了意義。同時(shí),“導(dǎo)案”的設(shè)計(jì)需要注重情境、語(yǔ)境的設(shè)計(jì)。

二、課前自學(xué)
1.課前熱身
(1) Could you please brainstorm as many ball games as possible?
(2) Which of the ball games do you like watching? Why?
(3) Which one of them are you good at?
2.課前閱讀

(3)Alexander Cartwright is called “the father of baseball” because he invented it.
(4)Compared with others, soccer was the first to be played by people.

(2)The court is divided into two main sections by the mid-court line.
(3)One of the simple rules—maximum of 15 players in a team, with up to 7 substitutes allowed.
