如何設計并用好“學教案”中的“預習案”

我的理解：實施“學教案”主要就是想轉變在原來被動、單一的學習方式下所造成的學生們逐漸失去學習興趣，喪失自己學習能力的狀況，力圖培養學生主動學習的精神，真正成為學習的主人，充分展示每一位學生的才華。 所以從這方面看，所有環節中預習案的設計顯得尤為重要。它肩負著培養學生自己學習的能力，完成“授人以漁”的重任！ 預習案的設計，首先要考慮到面向全體學生，要做到難易層次分明。為了讓每一位學生都知道如何著手進行預習，預習案應給出預習的具體實施步驟，從而降低預習的難度。設計時，要用學生的眼光看教材，用學生的認識經驗去感知教材，用學生的思維去研究教材，充分考慮學生在學習過程中可能遇到的思維問題。 通過預習案的設計，不僅呈現出本堂課所必須掌握的基礎知識，更要能一步一步地引導學生理解所學知識，最終可以運用所學知識解決實際問題。同時，教師還可以提供與所學內容相關的背景知識或資料予以拓展、開闊學生的眼界。 同時，在有效的預習案的幫助下，教師可以準確掌握學生的自學探究的信息反饋,把握教學目標和學情，從而切實達到“以學定教”，真正實現“高效課堂”。 另外，我認為對預習案的使用與教師對預習情況的檢查應僅限于是上課前的。最近聽了一堂課，課堂上，老師一開始就檢查預習的效果，按照學教案上羅列的教學任務開始一條一條的進行講解，不同的只是換由學生進行講解，這讓人感覺不用教師進行教學，學生其實已經掌握了教學內容，疏忽了教師精講點撥的重要作用。其實，既然我們用了“學教案”，就應該大膽放手讓學生去預習，合作探究。而不應該課堂上再把教學重點放在預習案上了。 我還發現，有的學教案的設計，僅僅是“教案”+“練習”，把教師上課的每一個環節甚至于要說的話，將用于檢測學生知識掌握的問題都打印在學教案上，課前印發給學生。這種情況上次北宋一中的李校長也有提到。他說他們學校是把預習案和其他分開來發放的。 所以，我想要能體現“學教案”精髓的、最理想的課堂還有待做細節上的推敲。以上僅是我的一些淺見，呵呵。希望我們共同努力，把我們的“學教案”做的更好！   附上我學教案中的預習案設計一則： 9A  Unit 2 Period 1  Comic strip + Welcome to the unit Analysis of Teaching materials 1. Teaching Goals  教學目標 To recognize the names of different colors To recognize the colors of the rainbow and the order of the colors 2. Important language points:教學重點 I’d rather wear blue than pink. There’s nothing wrong with pink. Blue looks good on you ! 3. Difficult language points:教學難點 To recognize the colors of the rainbow and the order of the colors 4. Instructions for preparation:預習指導 (1)Listen to the tape twice and answer the following questions while looking at the picture: Why would Eddie rather wear blue than pink? Does Eddie look nice on blue? Why not?   (2)Finish the following exercises: ① I’d rather wear blue than pink. 試譯: 她寧可要小的而不要大的. 我寧愿踢足球而不愿打籃球. ② There’s nothing wrong with pink. 試譯: 我在尋找一個特殊的人. 辦公室里正發生一件重要的事情. ③ Blue looks good on you. Eg: You look nice _____ blue. Cf: in the tree& on the tree; in the newspaper & on the newspaper; in the wall & on the wall; in the book & on the book ④ 寫出以上三句話的同義句. ⑤ Color: The boy doesn’t like _____(color) shoes. She likes _____(color) better than black and white. The child _____(color) these pictures. ⑥ orange: 橙子/橙色: An orange is orange. 橙汁: a glass of orange   (3)Listen and repeat after the tape, imitate the pronunciation and intonation and try to act out the dialogue.   (4)Think over or try to find the information about the following question: ① When can we see the rainbow?or How is a rainbow created? ② How many colors are there in the rainbow? What are they? ③ Write down the colors of the rainbow in order: ④ Draw a rainbow in pigment: ⑤ Extensive Reading  (1) Everybody likes to see a rainbow. It usually means that the rain will be finished soon and the sun will shine. To create a rainbow, you need both sun and rain at the same time. The sunlight shines through the raindrops which breaks up the light rays and makes the rainbow colours. A rainbow has only “true” colours. There is no black or white. Black is really the absence of colour, meaning no colour at all. White is all the colours together. It’s hard to believe! It is the splitting up or breaking up of white light that makes the rainbow colors we see. The raindrops act as a prism to the white light of the sun. With three colors, red, yellow, and blue, we can make all the other colours. These are the pure colors. You can’t mix anything together to make red or yellow or blue. These are the primary colors. However blue mixed with yellow makes green. Red and yellow create orange. Purple is a combination of red and blue. These are the secondary colors. What makes brown? Art students like to mix all the colors together to see what happens. The combinations of red/green, blue/orange, yellow/purple,cancel each other out leaving a muddy brown color. What a disappointment! Did you notice that the two colors in the group mentioned above contain one primary and one secondary color? Only in nature does the mixing of all colours make white light. Today, we see many mixtures of colours. Turquoise is blue and green together. White can be added to colours to make them lighter, like pink, for example. Grey is a blend of black and white together. Colours make our lives more beautiful and interesting. Next time you see a rainbow, enjoy the beautiful colors you see. Fill in the blanks with correct colors: Red+blue _____  Blue+yellow_____  Yellow+red___   (2) Red: of the color of blood Orange: reddish-yellow Yellow: of the color like that of butter, gold, or the middle part of an egg Green: the color of leaves and grass Blue: of the color of the clear sky or of the deep sea on a fine day Indigo: dark purplish blue Violet: a bluish purple color Pink: pale red   (3) Idioms: a phrase which means something different from the meanings of the separate words. Black sheep; in the pink; white lie; white elephant;
