In contrast, CF research conducted within a sociocultural framework has sought to show how tailoring the feedback to the learners' zone of proximal development assists learning (e.g. Aljaafreh and Lantolf, 1994).
Scaffolding refers to the temporary support provided to learners (by another person who might be more capable) to complete a task that they would not be able to complete independently and to facilitate the learners' zone of proximal development [ 70].
Here classroom situations and interactions, if pitched appropriately and meaningfully at learners' zones of proximal development, can help in diverse ways to scaffold people's acquisition of text forms, composing processes, and purposeful social interactions through writing in the second language.
Examples of dialogic mediation also showed the ways of providing appropriate mediation that is attuned to the learner's zone of proximal development.
That is, the role of the intelligent tutoring system is to keep the learner in the zone of proximal development (Vygotsky 1978) through an appropriate set of tasks with respect to the learner's current knowledge state.
In an earlier work, Aljaafreh and Lantolf ([1994]: 480) posit that, Effective error correction and language learning depend crucially on mediation provided by other individuals, who in consort with the learner dialogically co-construct a zone of proximal development in which feedback as regulation becomes relevant and can therefore be appropriated by learners to modify their interlanguage systems.
There, in hundreds of asynchronous conversations with peers in every time zone, thousands of learners are working out what they think about the intersection of the web with journalism and media, as they peer through the lens provided by this one particular company.
My commitment to them was to provide points of entry for all of them and to make sure that no learner was always out of his or her comfort zone.
Half a lifetime ago, Phelps told the station his other big concerns were adjusting to the new time zones when swimming abroad and getting his learner's permit to drive. .
This "zone" is the area of exploration for which the learner is cognitively prepared, but requires help and social interaction to fully develop it (UNESCO 2003).
