2、练技能操练技能The deductive method relies on reasoning,analysing and comparing.1.The rule is given first.2.The teacher explains the rules with examples(in the students native language and use grammatical terms,comparison may be done between the newly presented structure and previously learned structures la

3、nguage and the native language).3.Students apply the rules to given situations(practices).The deductive method（演绎法）语法呈现语法呈现 操练技能操练技能 Teacher writes:what are you doing?I am reading.Teacher reads and students repeat.Teacher explains this is the Present Conditions.Teacher explains that the form is:pron

5、ss.语法呈现语法呈现 操练技能操练技能The deductive method is criticized because:Grammar is taught in an isolated way;Little attention is paid to meaning;The practice is often mechanical.语法呈现语法呈现 操练技能操练技能However,the deductive method is not without merits.It could be very successful with selected and motivated student

6、s.It could save time when students are confronted with a grammar rule which is complex but which has to be learned.It may help to increase student confidence in those examinations which are written with accuracy as the main criterion of success.语法呈现语法呈现 操练技能操练技能The inductive method归纳法归纳法 Students ar

7、e given the structure in context(authentic or near authentic)&are asked to work out the rule for themselves.They are given guidance from the teacher in using evidence from the context to work out the usage of the structure.语法呈现语法呈现 操练技能操练技能 In the inductive method,the teacher induces the learners to

8、 realise grammar rules without any form of explicit explanation.It is believed that the rules will become evident if the students are given enough appropriate examples.Implicit grammar instruction 语法呈现语法呈现 操练技能操练技能T:what can you see in the picture?Ss:we can see a box,a heavy box.T:is it heavy?Ss:yes

9、,its very heavy.its 200kg.T:can I carry it?Ss:no,you cant.T:yes,you are right.I cant carry it.Why?Because it is too heavy to carry.语法呈现语法呈现 操练技能操练技能 As research indicates,grammar instruction should be mainly implicit,supported by explicit instruction.At the beginning stage,it is better to adopt main

10、ly the implicit approaches,and as students progress,the ratio of explicit instruction can be increased.语法呈现语法呈现 操练技能操练技能It is believed that the inductive method is more effective in that(=because)students discover the grammar rules themselves while engaged in language use.What they discover by thems

11、elves are better remembered.语法呈现语法呈现 操练技能操练技能But if the structure is not easy for the learners to discover themselves even with a contextprovided,it is better to teach the rule explicitly.语法呈现语法呈现 操练技能操练技能The best approach is the combination of both implicit and explicit instruction.语法呈现语法呈现 操练技能操练技

12、能Other presentation methodsListening to comprehend:the focus is on the message with target structures imbedded.Listening to notice:listen to more times to identify the target structure perhaps by completing a gapped version of the text to raise awareness.Understanding the grammar point:the focus is

13、on helping learners develop explicit knowledge of the grammar point by discovering and analyzing the rules.Checking:learners are given a written text containing errors and are asked to identify the errors and correct them.Trying it out:finally,there is an opportunity for students to try out their un

14、derstanding of the target structure in a short production activity.语法呈现语法呈现 操练技能操练技能Two categories of practice Mechanical practice Meaningful practice Grammar practice 语法呈现语法呈现 操练技能操练技能Mechanical practice Mechanical practice involves activities that are aimed at form accuracy.e.g.Substitution drills

15、Transformation drills 语法呈现语法呈现 操练技能操练技能Substitute the underlined part with the proper forms of the given words:green lawn clean house pretty garden nice flowersMrs Green has the largest house in town.语法呈现语法呈现 操练技能操练技能Change the following sentences into the past tense.Use the adverbs given in the bra

16、ckets.Now he lives in London.(last year,Paris)We have English and maths today.(yesterday,music and P.E.)He usually gets up at seven.(this morning,eight)语法呈现语法呈现 操练技能操练技能Meaningful practice In meaningful practice the focus is on the production,comprehension or exchange of meaning,though the students“

17、keep an eye on”the way newly learned structures are used in the process.e.g.After the presentation and mechanical practice of adjective comparatives and superlatives:语法呈现语法呈现 操练技能操练技能Pair work:Look at the table below.Rank the items on the left column according to the criteria listed on the top.Cheap

18、Healthy Tasty Fattening Important BeerWaterFruitCigarettesAlcoholMilk 语法呈现语法呈现 操练技能操练技能The students may come up with:I think beer is cheaper than fruit.No,no,I think fruit is cheaper than beer.语法呈现语法呈现 操练技能操练技能 Teacher:Now lets play a game.The first student starts a sentence with a second conditiona

19、l clause.The next student takes the result of the sentence,reforms it into another condition and suggests a further result.For example,the first student says“If I had a million dollars,I would buy a yacht”.The second students says“If I bought a yacht,I would go for a sail”.语法呈现语法呈现 操练技能操练技能The stude

20、nts may come up with:If I went for a sail,there might be a storm.If there were a storm,my yacht would sink.If my yacht sank,I would die.If I died,my parents would cry.语法呈现语法呈现 操练技能操练技能Using prompts for practicePractice based on prompts is usually meaningful practice.Using picture prompts.Using mime

21、or gestures as prompts.Using information sheet as prompts.Using key phrase or key words as prompts.Using chained phrases for story telling.Using created situations.语法呈现语法呈现 操练技能操练技能 语法呈现语法呈现 操练技能操练技能Using information sheet as promptsTeacher:What about you?Tell your neighbour.NamesFavourite subjectsF

24、d practice,half-controlled practice and communicative practice are all needed.语法呈现语法呈现 操练技能操练技能4.Emphasize inductive approach over deductive approach,though both approaches are essential.5.Use visible instruments such as charts,tables,diagrams,maps,drawings,and realia to aid understanding;语法呈现语法呈现 操练技能操练技能 以学生在英语实践中能正确运用语法知识为目的，避免让学生死记硬背语法规则。语法讲解力求简洁，呈现语法知识点力求直观、生动、使用，避免语法学研究式的研究。以归纳法为主，演绎法为辅。即多让学生通过例句归纳出语法规则，而以讲解较难的语法项目然后举例说明的方法为辅。尽量将语法教学置于情景教学中。通过大量听说读写译等教学活动来强化句型结构和语法规则的掌握。语法教学的原则和要求 语法呈现语法呈现 操练技能操练技能教学案例 Comparative of Adjectives
