In “Weaving Possibilities: Rethinking Metaphors for Early Literacy Development,” Dyson explains that “[w]hile scaffolding is a vertical metaphor, one that represents how more skillful others support [students’] progress within one activity, weaving has a more horizontal dimension. It suggests how [students’] progress in any one activity is supported by their experiences in varied activities.” (from NCTE Inbox Blog)
Scaffolding is the name many use for the instructional support students need and often get when they are working in their Zones of Proximal Development. Below is a bit of info on the term.
Scaffolding Theory was first introduced in the late 1950s by Jerome Bruner, a cognitive psychologist. He used the term to describe young children's oral language acquisition. ...Though the term [scaffolding] was never used by Vygotsky, interactional support and the process by which adults mediate a child’s attempts to take on new learning has come to be termed “scaffolding.” Scaffolding represents the helpful interactions between adult and child that enable the child to do something beyond his or her independent efforts. A scaffold is a temporary framework that is put up for support and access to meaning and taken away as needed when the child secures control of success with a task.
