摘要：AbstractAccording to Vygotsky (1978), a learner has the potential to progress from their actual developmental level to their potential developmental level via scaffolding that occurs during interaction with superior others. This case study was conducted based on Vygotsky's (1978) theory of scaffolding within the Zone of ProximalDevelopment (ZPD). In line with this theory, this case study attempted to examine the role of scaffolding via communicative activities in terms of development of basic speech on foreign language adult learners. At first the six students were given the main words of the sentences and the students were required to create sentences. Each time the number of main words of the sentence in an activity has been reduced; therefore, the students had to create the sentences with the help of the teachers. Then a series of pictures were given to the learners and they had to tell a story based on the pictures. The teacher provided few guided words with them if necessary. At the end of the course, the learners’ speech level had been improved surprisingly. Learning is significantly enhanced when the class atmosphere is in a cooperative and supportive mood. The results suggest that scaffolding within ZPD has its share in learner's basic speech development.
