即時性評價是指教學(xué)過程中，教師對學(xué)生的課堂表現(xiàn)做出及時、有效地評價。特點是：及時，也就是對學(xué)生的課堂表現(xiàn)即刻就能得到認可或糾正；有效，即評價能對學(xué)生以后的學(xué)習(xí)產(chǎn)生動力作用和指導(dǎo)作用。這不但起著反饋、激勵、調(diào)控和導(dǎo)向的作用，還對學(xué)生的健康成長與和諧發(fā)展具有重要意義。一方面對學(xué)生的好的表現(xiàn)得到及時的肯定，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(xí)奠定后續(xù)的精神毅力。另一方面，學(xué)生在學(xué)習(xí)和成長過程中，能得到科學(xué)的、靈活的快捷的反饋與指導(dǎo)，也會使學(xué)生對今后的發(fā)展信心倍增，使今后的教學(xué)互動更加有效，也更利于學(xué)生的終身學(xué)習(xí)習(xí)慣和能力發(fā)展。
案例分析：
九年級英語 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(xí)中，使課堂產(chǎn)生事半功倍的效果。)
II.教學(xué)過程：
Step one: words and expressions.
從詞匯開始，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”。
Zhao: million, M-I-L-L-I-O-N.
T:一百萬。
Zhao: a million
T:數(shù)以百萬計。
Zhao: millions of.
T: Good. Sit down, please. Next, Jiang Dandan , 醫(yī)學(xué)的（教師的評價顯得過于簡單，泛化，缺乏實效性）
J：Medical. M-E-D-I-C-A-L.
T:醫(yī)學(xué)研究。
J: medical research
T: Very good! sit down, please . Next ,…… (教師的評價內(nèi)容單一，語言模式化，師生互動不足 )
對話練習(xí)目標功能語言：（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.
（教師板書對話：
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)生會心地點點頭，說明適時的鼓勵與積極的評價能給同學(xué)們更大的學(xué)習(xí)動力，更能激發(fā)他們的進取心。學(xué)生也產(chǎn)生了繼續(xù)學(xué)習(xí)的濃厚興趣。但總體來看教師的語言缺乏維度，沒能針對不同的學(xué)生采取不同的語言來加以評價，并沒有將評價和學(xué)習(xí)內(nèi)容結(jié)合起來，為學(xué)生的學(xué)習(xí)奠定后續(xù)力量。)
Step tow: Presentation
（Ⅰ）學(xué)習(xí)新內(nèi)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)生們積極的進行著讀與理解的訓(xùn)練，并且不同層次的學(xué)生都在努力地學(xué)習(xí)應(yīng)學(xué)會的內(nèi) 容，通過自由結(jié)合學(xué)習(xí)使學(xué)生的積極性進一步提升。)
At the same time the teacher wrote some exercises on the blackboard.（板書內(nèi)容：
左：Ⅰ
1.I don’t know _____________________（說什么、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(jié)，學(xué)生能積極的進入角色，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價有一定的及時性，但這樣的評價對學(xué)生來說沒有藝術(shù)性和導(dǎo)向性，而且還是較為單調(diào)，缺乏針對性、指導(dǎo)性。）
�。á颍┥罨喿x練習(xí)，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(xí)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(jié)，體現(xiàn)了教學(xué)的層次性，進行了考試技能的訓(xùn)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.（此時教師并未給出較為積極的評價，體現(xiàn)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(jié)中，雖然教師并未對學(xué)生做出積極的評價與鼓勵，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(jié)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(jié)性評價缺乏，會使學(xué)生對本節(jié)課產(chǎn)生不了滿足感、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，教師一直沒有做出較好的、具有一定層次性的評價。學(xué)生們需要評價和鼓勵，這也是從長遠的學(xué)習(xí)效果來看的，教師如果進行了多維度、分層次 準確得體、具有導(dǎo)向性和發(fā)展性評價，學(xué)生一時的學(xué)習(xí)效果和今后自主學(xué)習(xí)能力的提升會更加的明顯。
總而言之，教師能不能引導(dǎo)學(xué)生形成自主學(xué)習(xí)、自覺學(xué)習(xí)的習(xí)慣甚至是能力，關(guān)鍵是教師的評價機制、原則和能力的一個充分體現(xiàn)。
