More recently research has focused on several different factors that affect individuals’ language learning, in particular strategy use, social and societal influences, personality, motivation, and anxiety. The relationship between age and the ability to learn languages has also been a subject of long-standing debate. Empirical research with second language learners supports the contention that engaging in language interactions facilitates second language development. Findings from a study to determine how conversational interaction affects the acquisition of question formation indicate that interaction can increase the pace of acquisition . Research on interaction includes studies of task-based language learning and teaching and focus on form.
In a study, Singaporean elementary school students who were learning both English and Mandarin showed signs of language convergence. In this study, these students showed a preference for using grammatical patterns common in Mandarin when speaking English. Language convergence occurs because the children are not only acquiring the grammar of the new language but still developing the grammar of their native language, so the two grammars converge. They note that SLA ‘has totemic value at the present time’ (p. 5) and retain it to refer to the historical canon only. Following Leung and Valdés, Anderson , in his integrated curriculum framework for language teaching, also avoids SLA, preferring ‘additional language learning’ (p. 175) as his alternative.
This unsourced knowledge suggests the existence of a universal grammar. Another piece of evidence that generative linguists tend to use is the poverty of the stimulus, which states that children acquiring language lack sufficient data to fully acquire all facets of grammar in their language, causing a mismatch between input and output. The fact that children are only exposed to positive evidence yet have intuition about which word strings are ungrammatical may also be indicative of universal grammar. However, L2 learners have access to negative evidence as they are explicitly taught about ungrammaticality through corrections or grammar teaching.
Factors and approaches to SLA
Survey books of SLA begin by telling their readers the reasons for investigating SLA. In Ellis (Reference Ellis 1985; Reference Ellis 2015), I identified the primary purpose of the book as helping teachers construct ‘a theory of language learning that is explicit and therefore open to revision’ (p. 3). This reflects the underlying rationale for much of the early SLA research – helping to make language teaching more effective.
However, some differences that are generally agreed upon include older learners having a noticeable accent, a smaller vocabulary, and making several linguistic errors. Immersion programs provide a sociolinguistic setting that facilitates second-language acquisition. Immersion programs are educational programs where children are instructed in an L2 language. Although the language of instruction is the L2 language, the curriculum parallels that of non-immersion programs and clear support exists in the L1 language, as the teachers are all bilingual. The goal of these programs is to develop a high level of proficiency in both the L1 and L2 languages.
There have been several models developed to explain social effects on language acquisition. Schumann’s Acculturation Model proposes that learners’ rate of development and ultimate level of language achievement is a function of the “social distance” and the “psychological distance” between learners and the second-language community. In Schumann’s model, the social factors are most important, but the degree to which learners are comfortable with learning the second language also plays a role.

In general, etic research investigates groups of learners while emic research aims for rich data about individual learners. The morpheme studies of the 1970s involved groups and, with a few exceptions, were cross-sectional but the studies investigating transitional constructions at this time investigated individual learners and were longitudinal. In the expansion and cognitive phases of SLA, researchers investigated groups of learners in cross-sectional studies. Social turn researchers prioritized individuals but rarely longitudinally . Larsen-Freeman (Reference Larsen-Freeman 2018) emphasized the importance of investigating individual learners. She disputed the assumption that group averages can say anything about the population under investigation.
Transfer can be positive, i.e. promote learning, or negative, i.e. lead to mistakes. Of the 63 languages analyzed, the five most difficult languages to reach proficiency in speaking and reading, requiring 88 weeks , are Arabic, Creating python2 environment in conda GitHub Cantonese, Mandarin, Japanese, and Korean. The Foreign Service Institute and the National Virtual Translation Center both note that Japanese is typically more difficult to learn than other languages in this group.
- Recent research looks at how instructional contexts also affect motivation.
- Textbooks that offer flexibility to an instructor desiring to introduce some focus on form in the communicative classroom include those that incorporate a variety of activities–video, audio, and Internet-based activities.
- Teaching programs, textbooks, curriculum designs, and even the activities in your language classrooms are often informed by SLA research.
- For example, Spanish speakers learning English may say “Is raining” rather than “It is raining”, leaving out the subject of the sentence.
In the case of native English speakers, some estimates were provided by the Foreign Service Institute of the U.S. Department of State — which compiled approximate learning expectations for several languages for their professional staff . Category II Languages include German, Haitian Creole, Indonesian, Malay, and Swahili (approx. 36 weeks or 900 class hours).

The world’s largest enterprises use NETSCOUT to manage and protect their digital ecosystems. This last item is critical; service requirements and vendor capabilities change, so there must be a way to make sure the SLA https://bitcoin-mining.biz/ is kept up-to-date. SLAs are a critical component of any outsourcing and technology vendor contract. Beyond listing expectations of service type and quality, an SLA provides remedies when requirements aren’t met.
It protects both parties, and, should disputes arise, will specify remedies and avoid misunderstandings. That can save considerable time and money for both customer and supplier. Provider and customer agree to put a certain percentage of monthly fees (typically equal to the vendor’s profit margin) “at risk” from which these credits are drawn when SLAs are missed. This approach is intended to incentivize provider performance without being overly punitive. Cloud vendors are more reticent about modifying their standard SLAs because their margins are predicated on providing commodity services to many buyers.
What should I consider when selecting metrics for my SLA?
The next phase represents a ‘coming of age’ (Sharwood-Smith, Reference Sharwood-Smith 1994). It is really an extension of the previous one but I prefer to view it as distinct because it reflected the impact that constructs taken from cognitive psychology had on thinking about L2 acquisition. Information-processing theories are premised on an input-output view of learning and what Lantolf called the ‘computational model’. During this period, too, interest in implicit and explicit learning led to a refinement of Krashen’s earlier ‘acquisition’ and ‘learning’ distinction. Another area of controversy concerned whether language learning involved skill-learning (i.e. where the starting point was declarative knowledge) or was an essentially implicit process.
These three articles presented the case for viewing L2 acquisition as a transitional process where learners tested hypotheses in much the same way as in L1 acquisition. These articles motivated what had been previously lacking – the empirical study of learner language. Other researchers, such as DeKeyser , are fearful that SLA is disintegrating and are keen to move SLA into its mature stage by culling theories and striving for a unified approach. There are recent signs of this happening in Complex Dynamic Systems Theory.
It consists of a set of principles, which are universal and constant, and a set of parameters, which can be set differently for different languages. The “universals” in universal grammar differ from typological universals in that they are a mental construct derived by researchers, whereas typological universals are readily verifiable by data from world languages. There is an ongoing debate among generative linguists surrounding whether L2 users have full or partial access to universal grammar.
This body of research testifies to a general development in SLA – the increasing concern with the validity of the methods employed. I have included sociocultural SLA in this period although it constitutes a very different kind of social turn and pre-dated Firth and Wagner . As applied to SLA, sociocultural theory emphasizes the role that mediation plays in the initial development and subsequent internalization of new knowledge. Unlike other social theories, it recognizes the ‘mind’ as a central component in learning.
