(Excerpted from my dissertation.)
Learning a second language is an arduous task. Most scholars would agree that it requires a lot of practice (Krashen, 1982; Nation, 2014), language activities that are embedded in realistic tasks (i.e., communicative approach) (Hymes, 1972; McFarlane, Sparrowhawk, & Heald, 2002), plasticity of the brain (Pinker & Bloom, 1990; Ward, 2010), and high levels of motivation (Crystal, 2010; Gardner, 1985). Here are the five stages of second language (L2) learning: preproduction, early production, speech emergence, intermediate fluency, and advanced fluency (Krashen & Terrell, 1983). Progress through these stages depends on level of formal education, family background, time spent in an English-speaking country, and many other variables.
For young children, oral language and literacy development should include support in their native language, sufficient time and support, developmentally and culturally appropriate material, a balanced and meaningful literacy program, and reliable, ongoing, and valid assessments (TESOL, 2010a). For adults, more specialized vocabulary and education on the sociocultural dimensions for the workplace or academic setting are required (TESOL, 2010b). Otherwise, adult L2 instruction is like that of young children, as noted in the vision and action agenda of the National Literacy Summit (2000). For example, they propose that adult learners also have access to native language or bilingual texts and instruction that is based on meaningful contexts.
There’s some disagreement as to the developmental stages of SLA, but most agree that the initial stage includes a silent period in which you understand some of the L2 but may not be able to produce it (Granger, 2004). Scholars disagree as to whether there is a critical period (cut-off time) for learning a second language with native-like fluency (Crystal, 2010). For instance, cognitive neuroscientists prefer the term sensitive period to refer to the limited window of time to learn due to evidence supporting the possibility of extended learning (Ward, 2010).
I agree with Pinker and Bloom’s (1990) idea that the critical period varies with maturation and plasticity of the brain due to natural selection. Hurford (1991), in his evolutionary model, referred to language learning past the critical age as the natural selection pressures activating the trait. These pressures affect adults who come from around the world with the hope of learning English in order to attend an American university. One way to affect the plasticity of the brain is to play video games. Current research on the brain and its behavior indicate that playing highly arousing, reward-based video games activates brain plasticity (Kilgard & Merzenich, 1998).
Numerous factors affect learning ESL. For one, learning English takes a long time. For beginners, basic interpersonal communication skills can take two years to learn, while cognitive academic language proficiency can take five to seven years (Cummins, 2008). Influential factors include, but are not limited to, native language (L1) writing system, age exposed to English, cognitive ability, and exposure to other languages (National Literacy Summit, 2000). Another important factor is gender (i.e., female, male, other), which is influenced by the gender of the teacher, strategy use (Kiram, Sulaiman, Swanto, & Din, 2014), and conventional norms (Oxford & Nyikos, 1989). There’s no conclusive evidence that one gender is better at learning a L2. Oxford and Nyikos (1989) posit that it has more to do with strategy preferences and conventional norms.
