即時(shí)性評價(jià)是指教學(xué)過(guò)程中，教師對學(xué)生的課堂表現做出及時(shí)、有效地評價(jià)。特點(diǎn)是：及時(shí)，也就是對學(xué)生的課堂表現即刻就能得到認可或糾正；有效，即評價(jià)能對學(xué)生以后的學(xué)習產(chǎn)生動(dòng)力作用和指導作用。這不但起著(zhù)反饋、激勵、調控和導向的作用，還對學(xué)生的健康成長(cháng)與和諧發(fā)展具有重要意義。一方面對學(xué)生的好的表現得到及時(shí)的肯定，使他們產(chǎn)生心理的愉悅，以做出更加積極的努力，為學(xué)生的學(xué)習奠定后續的精神毅力。另一方面，學(xué)生在學(xué)習和成長(cháng)過(guò)程中，能得到科學(xué)的、靈活的快捷的反饋與指導，也會(huì )使學(xué)生對今后的發(fā)展信心倍增，使今后的教學(xué)互動(dòng)更加有效，也更利于學(xué)生的終身學(xué)習習慣和能力發(fā)展。
案例分析：
九年級英語(yǔ) Unit 4 What would you do? Section B Lesson One
I.組織課堂：（二分鐘）
Ss （standing）：Good morning，Mr.Yang.
T: Good morning, class. It’s a fine day, isn’t it?
Ss: Yes ,it is.
T: How do you like today?
Ss: We feel comfortable about it.
T: Very good. I hope we all have good feelings in a new day. Let’s begin our new lesson today.
(課前交流可以讓學(xué)生放松一下心情，并能以輕松愉悅的、積極地心態(tài)投入到課堂學(xué)習中，使課堂產(chǎn)生事半功倍的效果。)
II.教學(xué)過(guò)程：
Step one: words and expressions.
從詞匯開(kāi)始，為教學(xué)掃清障礙（五分鐘）
T： Dear class！ Today we’ll learn Section B. Before our new lesson, first, let’s review words and expressions we’ve learnt for this lesson. Zhao Zhiguang,“百萬(wàn)”。
Zhao: million, M-I-L-L-I-O-N.
T:一百萬(wàn)。
Zhao: a million
T:數以百萬(wàn)計。
Zhao: millions of.
T: Good. Sit down, please. Next, Jiang Dandan , 醫學(xué)的（教師的評價(jià)顯得過(guò)于簡(jiǎn)單，泛化，缺乏實(shí)效性）
J：Medical. M-E-D-I-C-A-L.
T:醫學(xué)研究。
J: medical research
T: Very good! sit down, please . Next ,…… (教師的評價(jià)內容單一，語(yǔ)言模式化，師生互動(dòng)不足 )
對話(huà)練習目標功能語(yǔ)言：（十分鐘）
T:Now let’s practice dialogues. We’d better use the expression we’ve learnt in this unit----If clause. We’ll practice three minutes and then ask some students to write down their answers. Ok let’s begin.
（教師板書(shū)對話(huà)：
A：I can’t study anything well. I’m not good at studying. Your advice, please?
Sa: If I were you , I’d read aloud books.
Sb: If I were you, I’d……
Sc: …… ）
(Three minutes later.)
T：Ok.who will come here and write down your sentence. At most five.
(five students came to the blackboard and wrote down what they wanted to say. )
The sentences are :
Deng Jingjing : If I were you, I’d read more easy and short English stories.
Jiang Dandan : If I were you , I’d ask the teacher for help.
Huang Xuan : If I were you ,I’d work harder than anyone else.
Deng Ruirui: If I were you , I’d learn from others .
Guo Panpan: If I were you , I’d study with friends and discuss
with them.
T: From these sentences, we can find we all can find ways to learn English better. I hope we can get better marks and high abilities. (學(xué)生會(huì )心地點(diǎn)點(diǎn)頭，說(shuō)明適時(shí)的鼓勵與積極的評價(jià)能給同學(xué)們更大的學(xué)習動(dòng)力，更能激發(fā)他們的進(jìn)取心。學(xué)生也產(chǎn)生了繼續學(xué)習的濃厚興趣。但總體來(lái)看教師的語(yǔ)言缺乏維度，沒(méi)能針對不同的學(xué)生采取不同的語(yǔ)言來(lái)加以評價(jià)，并沒(méi)有將評價(jià)和學(xué)習內容結合起來(lái)，為學(xué)生的學(xué)習奠定后續力量。)
Step tow: Presentation
（Ⅰ）學(xué)習新內容，提升閱讀能力（二十分鐘）
T：Now , let’s learn more .Turn to page28. Read and try to understand the meaning of it. Give you five minutes. If you have problems , you can move and ask others in class. (學(xué)生們積極的進(jìn)行著(zhù)讀與理解的訓練，并且不同層次的學(xué)生都在努力地學(xué)習應學(xué)會(huì )的內 容，通過(guò)自由結合學(xué)習使學(xué)生的積極性進(jìn)一步提升。)
At the same time the teacher wrote some exercises on the blackboard.（板書(shū)內容：
左：Ⅰ
1.I don’t know _____________________（說(shuō)什么、做什么）.
2. 參加考試_________________ 3.散 步______________
4.在某方面幫助某人___________ 5.太……而不能……_____________
中：Ⅱ
The first person is ___________________________.
He should _____________________________________
The second one gets ____________________________
He should _____________________________________
The last one can’t ____________________________
He should _____________________________________ ）
（Five minutes later）
T：Who will be brave enough to come here and read a passage?
Ren Mengyu came to the blackboard and began to read the first passage. Then Meng Haoting 、 Wu Dandan 、Wu Rujie 、Tian Lulu and Wang Ruijie came and read one by one.（在本環(huán)節，學(xué)生能積極的進(jìn)入角色，順利的完成閱讀的任務(wù)。）
T: Very good. We all have done well. Let’s do more . ……
�。ń處煹脑u價(jià)有一定的及時(shí)性，但這樣的評價(jià)對學(xué)生來(lái)說(shuō)沒(méi)有藝術(shù)性和導向性，而且還是較為單調，缺乏針對性、指導性。）
�。á颍┥罨喿x練習，激發(fā)學(xué)生潛能力（十分鐘）
T：Our next task is to find out how to fill in the blanks in the middle of the blackboard. If you can’t do those, please match the problems and advice in 3a.You can move and discuss if necessary. In ten minutes, you can come and finish them .(學(xué)生的學(xué)習興趣更加高漲)
（Six minutes later）Sun Lulu 、Wang Yuanyuan 、Deng Jingjing came and filled blanks. Other students gave their opinions.(本環(huán)節，體現了教學(xué)的層次性，進(jìn)行了考試技能的訓練，對學(xué)生的能力是很好的鍛煉和磨練。)
T：We’ll come to our last task in this lesson. Now let’s read the text again and find out some useful things together. Something can help you is on the left of the blackboard.（此時(shí)教師并未給出較為積極的評價(jià)，體現不出教師教學(xué)的機智與巧妙，詼諧幽默，不能使學(xué)生的積極性達到高峰。）
(Three minutes later , some Ss finished those and they gave exact explanations.)（本環(huán)節中，雖然教師并未對學(xué)生做出積極的評價(jià)與鼓勵，但有些題目他們可以給出多種答案、解釋。這是學(xué)生發(fā)揮出自己的創(chuàng )造性、積極性的結果。）
T：Our task after class is practicing speaking using the target language we’ve learnt in this lesson. We can practice as part four on page28 (the bell is ringing) OK. Let's have a rest and hope you have a good time all day long.
Ss: The same to you, Mr. Yang .See you.
(教師的課后總結性評價(jià)缺乏，會(huì )使學(xué)生對本節課產(chǎn)生不了滿(mǎn)足感、成功感、愉悅感，又怎能使學(xué)生對下一次課堂產(chǎn)生期待與憧憬呢？)
從整堂課看，教師一直沒(méi)有做出較好的、具有一定層次性的評價(jià)。學(xué)生們需要評價(jià)和鼓勵，這也是從長(cháng)遠的學(xué)習效果來(lái)看的，教師如果進(jìn)行了多維度、分層次 準確得體、具有導向性和發(fā)展性評價(jià)，學(xué)生一時(shí)的學(xué)習效果和今后自主學(xué)習能力的提升會(huì )更加的明顯。
總而言之，教師能不能引導學(xué)生形成自主學(xué)習、自覺(jué)學(xué)習的習慣甚至是能力，關(guān)鍵是教師的評價(jià)機制、原則和能力的一個(gè)充分體現。
