General questions in SLA research
• What do second language learners acquire? • How do learners acquire a second
language? • What differences are there in the way in
• How do learners acquire a particular TL linguisitic feature? E.g. interrogatives
• The sequence of acquisition(学习者习得某 个特定语言项目时所经历的动态发展过程)
进行时-ing，复数s,系动词be
2.production accuracy
1. Instruction only aids the acquisition of features that are formally easy to acquire. It denpends on the complexity of the target structure.
助动词be, 冠词a/an the
动词过去式的不规则形式
动词过去式的规则形式-ed,动词现在 时第三人称单数s,所有格’s
The sequence of learning English interrogatives
S 1: he work today? Sir play football today?
which individual learners acquire a second language? • What effects does instruction have on second language acquisition?
General questions in SLA research
2.Grammmar instruction may prove powerless to alter the natural sequence of acquisition of developmental structures.
benefits for SLA?
Does classroom instruction have any benefits for SLA?
• 1. general language proficiency • in acquisition-rich or acqusition-poor
environments • children or adults
2. formal instruction has an effect on accuracy in planned but not unplanned production.
3. Formal instruction has a delayed effect.
4. Formal instruction can also impede acquisition by making learners too conservative and learners tend to simplify if going beyong their current language level.
S 2: What you (are) doing? Where you go?
S 3: Can you speak English? How can you say that?
S 4: Does she like where she lives?
1.Instructed learners manifest the same order of morpheme acquisition as naturalistic learners.
• If the structure is simple in the sense that it does not involve complex processing operations and if the formal instruction is extensive and well-planned, it is likely to result in accuracy.
• What do second language learners acquire? • How do learners acquire a second
language? • What differences are there in the way in
which individual learners acquire a second language? • What effects does instruction have on second language acquisition?

3. the order & sequence of acquisition 第二语言习得顺序
• Do learners acquire some target-language features before others?
• The order of acquisition (学习者习得多个 不同语言项目时的次序)
• If the instruction is directed at a difficult grammatical structure which is substantially beyond the learners’ current interlangage, it is likely that it will only lead to improved accuracy in planned language use.
What effects does instruction have on second language acquisition?
• Acquisition :informal/formal learning • Classroom instruction=formal learning • Does classroom instruction have any
