It is widely known that the scaffolding plays a very important role in the field of architecture. While it also widely used in the education which used as a teaching strategy accepted by a lot of people here. Today I will introduce it definitely for you.
 
 Well. First let us come to the definition of it. The theory of "scaffolding" someone's efforts to learn describes how a learner can be supported to achieve a task or develop a skill. A learning scaffold usually takes the form of verbal pointers---the questions, prompts or clues given by the instructor---but written materials or physical equipment may play a part. Just as a new building is surrounded by scaffolding poles as it is being put up, so a new learner may need different kinds of support to make progress.
 
 Next is the history of it. The term "scaffolding learning" was coined in the 1970s by the U.S. psychologist Jerome Brune. He noted tactics such as repetition, the asking of questions and the modeling of phrases for the child to complete. Bruner's work built upon that of Russian psychologist Lev Vygotsky, who described a "Zone of Proximal Development," an area of learning containing tasks too difficult for a child to master alone, but which could be managed with the guidance of someone more skilled.
 
 The Characteristics of it are as follows. Any helpful interaction between an expert and a novice could be described as scaffolding. But for Vygotsky and Bruner, social interaction, the dialogue between expert and novice, is the most important element. Providing a child with counting cubes might be seen as scaffolding.
