Symbolic Mediation Internalization Learning Process And Zpd Education Essay

Symbolic Mediation Internalization Learning Process And Zpd Education Essay Second language acquisition (SLA) is a relatively new field, which was seen as an adjunct of language teaching pedagogy before 1960s (Myles, 2010). Ellis (1994) defined three aspects that are responsible for L2 acquisition: external factors (social factors, input and interactions); internal factors (learners existing knowledge and internal mechanisms) and individual learner factors (P. 193). The social factors was investigated under heavy influence from Vygotskys Zone of Proximal Developments (ZPD). In this paper, major focus would be around the notion and application of ZPD, including: defining ZPD and key concepts of Vygotskys theory relating to ZPD: symbolic mediation, internalization,learning process, the role of interlocutor and learner; comparing Vygotskys social cultural theory (SCT) with Piagets cognitive theory; comparing Vygotskys Zone of Proximal Developments with Krashens notion of i+1 hypothesis Symbolic mediation, internalization , learning process and ZPD The social-cultural theory, stemmed from Vygotskys thoughts claims that the language learning process is socially mediated (Lantolf, 2000). Lantolf (1994) stressed that from Vygotskian perspective, the higher forms of human mental activity are always, and everywhere, mediated by symbolic means (P. 418) The symbolic mediation refers to the external process via symbolic signs or tools in social context through which learner can control mental process after internalization (Lightbown Spada, 2006). Lantolf (2000) regards language, among all the symbolic tools, as the most powerful psychological tool (P. 81). Through the mediation of language, the child or learner learns how to perform a task or solve a problem with the help from a more skilled individual (Mitchell Myles, 2004). In other words, the learning process starts as an inter-mental activity, by the more skilled individual sharing through talk, and ends as an intra-mental activity, with the shared knowledge taken in by the unski lled individual. Thus, according to Vygotsky, learning includes two stages: shared understanding in social context through symbolic mediation (mainly in the form of dialogue) and internalization of the shared knowledge by individual. The learning process from a Vygotskyan perspective is described as new concepts continue to be acquired through social/interactional means (Mitchell Myles, 2004, P. 147). Vygotsky defines the concept of zone of proximal development (ZPD), as the distance between the actual developmental level as determined by independent problem solving and the level of potential development as determined through problem solving under adult guidance or in collaboration with more capable peers (Vygotsky, 1978, p. 86). In other words, the role of more advanced interlocutor is stressed by assisting individual crossing the gap between actual level (what the learner can do alone) and potential level (what the learner can achieve with help). The learner is cognitively prepared for solving more complex problems if supported by an interlocutor. More importance has been attached to social interaction between learner and interlocutor, which is regarded as a causative force in acquisition (Saville-Troike, 2006, P. 111). Vygotsky versus Piaget Zuengler and Miller (2006) reviewed the ongoing debates on whether a separation should be made between second language acquisition and second language use and the debates on the commensurability of theories from different schools. It may be interesting to notice that the differences between sociocultural theory and cognitive theory bear relationship with their origins -Vygotsky, the father of socioculture theory and Piaget, the father of cognitive theory. Piaget and Vygotsky are among the earliest proponents to link childrens language development with their cognitive development (Lightbown Spada, 2006). For Piaget, the cognitive development for children is realized through interaction with things around them and is presented by language which is not different from Vygotskys view. They share the view of learner as a social human being who are learning through interaction with environment and of learning and development as a contextually embedded process of interactions (Vianna Stetsenko, 2006, P. 85). However, the dissimilar emphasis that they place on social interaction leads to three major differences. For Piaget, children learn and develop in the environment. For Vygotsky, children not only learn and develop in the environment but also change it through interaction. Therefore, for Vygotsky, language is seen as a more powerful symbolic mediation (Lightbown Spada, 2006). The second difference is adaption versus transformation (Vianna Stetsenko, 2006, P. 87). For Piaget, human develop by assimilation and accommodation to adapt to the environment, whereas for Vygotsky, human develop by actively changing the environment. The third difference lies in their view of the priority between learning and cognitive development. For Piaget, children need to be cognitively prepared to a certain stage before learning, while for Vygotsky, precedence is given to learning instead of development. Therefore, Vygotsky argue for teaching or learning within ZPD, where learners could do more with scaf folding from interlocutors than their independent performance (Zuengler Miller, 2006). ZPD versus i+1 Second language scholars have suggested the feasibility of integrating Krashens i+1 with Vygotskys zone of proximal development (ZPD) based on their similarities. Dunn and Lantolf (1998) have stated the incommensurability of these two concepts not only because they are unrelated but also because they are based on incommensurable theoretical discourses (P. 411) In Krashens view, humans acquire language in only one way-by understanding messages, or by receiving comprehensible input . . . that contains structures at our next stage- structures that are a bit beyond our current level of competence (Krashen, 1985, p. 2). More specifically, three factors contribute to language learning learners internalized grammar,namely the i, input containing linguistic structure a bit beyond learners current level, namely the i+1 and learners internal language processing mechanism (LAD) For Vygotsky, as mentioned above, ZPD is defined as those functions that have not yet matured but are in the process of maturation (1978, p. 86). A more holistic picture has been drawn with respect to language learning learner, interlocutor, their social cultural backgrounds, their goals and motives and all the resources available (Dunn Lantolf, 1998). Learning and development occur in both situations, where learner will surpass their current level either with assistance from a more advanced interlocutor within learners ZPD or with acquisition of linguistic structure i+1, which may contribute largely to their seemingly similarities. However, it would be cautious to notice as well that the development occur with a comparison of learners current level, that is learner himself. Therefore, it would be less justifiable to view the development in Krashens term as an equivalent to that in Vygotskys theory. Also it would be more reasonable to notice that the construct of ZPD and i+1 cannot stand without considering the theocratical frame that they root in respectively. Therefore, a comparison would be made between theories that have incubated these two constructs with respect to the relationship between learning and development, the consequence of learning, the role of language, learner and interlocutor and the role of social interaction. The fundamental difference between Krashens theory with Vygotskys theory is their diverse view on the relationship between instruction learning and cognitive development. Krashen hold the view as a separatist, who perceive learning under instruction and cognitive development as two independent process (Dunn Lantolf, 1998, P. 491). Therefore, Krashen intentionally draw a line between learning and acquisition, arguing that only though subconscious acquisition can comprehensible input be acquired, and learners cognition be developed. Conversely, Vygotsky presented a dualistic quality to development, that is whether learning consciously or not, a mutual influence exists between learning and development ( Dunn Lantolf, 1998, P. 491). Thus, learners are learning and developing at the same time, and the site where learning and development meet is called ZPD. Secondly, Krashen and Vygotsky differ in their view of the consequence of learning, based on their divergent view on learning and development. For Krashen, the outcome of learning is the linguistic structure that is a bit beyond learners current level, and with the acquisition of this feature, learner has developed cognitively, ready to obtain the next i +1. Whereas for Vygotsky, learners are developing along the whole learning process, which means that not only the immediate future, but also the maturing process account for development (Dunn Lantolf, 1998, P. 422). Therefore, it is the variability between acquisition and Internalization (Kinginger, 2002, P. 418). Thirdly, the roles of language, learner and interlocutor are interpreted differently. From Krashens point, language is conceived as a container of linguistic features with comprehensible input and learner as a container with Language Acquisition Device (LAD), the individual process mechanism built inside minds, and the assistance from interlocutor is not necessary (Dunn Lantolf, 1998, P. 418). In contrast, from Vygotskys perspective, language is one of the the most powerful psychological tool of semiotic mediation system (Lightbown Spada, 2006, P. 81), and thus representing the mediated forms of cognition (Dunn Lantolf, 1998, P. 426). Both learner and interlocutor are portrayed as a social human being, with motivation and social cultural identity, instead of a loner with an innate ability to process (Kinginger, 2001, P. 419). Moreover, unbalanced attention is given to social interaction in the frame developed by Krashen and Vygotsky. Krashen assigned relatively little importance to social interaction due to the existence of LAD, despite his support for a weak form of interaction: meaning negotiating proposed by Long (1996). In other words, Krashen argues that the strong form of interaction such as scaffolding or peer collaboration as well as learner output bear no direct relevance to SLA (Dunn Lantolf, 1998). In contrast, social interaction is viewed as the medium and the result of development by Vygotskian scholars (Kinginger, 2001, P. 422). Thus in order to maximize learners acquisition, interlocutor should scaffold the learner along ZPD and learners comprehensible output is as important as comprehensible input. Conclusion Over the past decade, there has been an increasing number of SLA researches conducted under the influence of socioculture theory (SCT) based on the work of Vygotsky (Ableeva Lantolf, 2011; Brooks Swain et al., 2010; Kinginger, 2002; Knouzi Swain et al., 2010; Lantolf, 2007; Foster Ohta, 2005; Swain Deters, 2007; Swain Lapkin et al, 2009). This theory differs from other theory describing the SLA in the stance that social environment is not only a learning context but rather a significant contributor to language acquisition (Swain Deters, 2007). Thus the concept built in SCT framework such as ZPD, cannot be viewed separately away from its origin, which implies that it would be best for any future comparison or commensuration of concepts from unlike theories be made with their roots considered. Also the incommensurability precisely add the value to the theory building in SLA field, not only for the sake of the this particular school itself but also for a helpful reflection for ot her schools.It is with this sharp comparison between different perspectives, a more holistic picture can be draw for L2 acquisition, despite the criticisms been made and the debates ongoing (Zuengler Miller, 2006). Lantolf (1996) have shown his welcome for a future of letting all the flowers bloom in SLA theory building and I simply cannot agree more with him (P.713-49).
