APPROACHES AND MODELS INVOLVING THE CONCEPT OF INSTRUCTIONAL SCAFFOLDING

Instructional scaffolding stems from Vigotsky' s view on supplementary learning.The theoreti-cal framework of instructional scaffolding,based on Vigotsky' s concept of approximate development area,isapposed to Piajet' s structuralist cognition which emphasizes learning process.Close to the instructional scaf-folding is the input supposition,or“1+1”comprehensible input concept.Instructional scaffolding as an in-structional strategy can stimulate the learning transfer in such areas as cognition,emotion,strategy,tech-niques.IN the process of instructional scaffolding,teachers tend to provide 3 scaffolds-vehicle scaffold,task scaffold and material scaffold.Instructional scaffolding optimizes the results of learning,but it has itslimitation in application.Therefore,“natural development”and“scaffolding method of teaching”are mutual-ly complementary.
