scaffolding is a vygotskian term that refers to ____
Zone of proximal development The concept of the ZPD is widely used to study children's mental development as it relates to education. The ZPD concept is seen as a scaffolding, a structure of "support points" for performing an action.[12] This refers to the help or guidance received from an adult or more competent peer to permit the child to work within the ZPD.[13] Although Vygotsky himself never mentioned the term, scaffolding was first developed by Jerome Bruner, David Wood, and Gail Ross, while applying Vygotsky's concept of ZPD to various educational contexts.[5] According to Wass and Golding, giving students the hardest tasks they can do with scaffolding will lead to the greatest learning gains.[14]
Excavation (archaeology) The process of excavation is achieved in many ways depending on the nature of the deposits to be removed and time constraints. In the main, deposits are lifted by Trowel and Mattock and shovelled or carried from the site by wheel barrow and bucket. The use of many other tools including fine trowels such as the plaster's leaf trowel and brushes of various grades are used on delicate items such as human bone and decayed timber. When removing material from the archaeological record some basic guidelines are often observed.
