The Federal Wage System (FWS) was developed to make the pay of Federal blue-collar workers comparable to prevailing private sector rates in each local wage area. Before the FWS, there was no central authority to establish wage equity for Federal trade, craft, and laboring employees.
 Zone of proximal development  (ZPD) is Vygotskyâs term for the range of tasks that a child is in the process of learning to complete. The lower limit of ZPD is the level of skill reached by the child working independently (also referred to as the childâs actual developmental level).ygotsky also posited a concept of the zone of proximal development, often understood to refer to the way in which the acquisition of new knowledge is dependent on previous learning, as well as the availability of instruction. During his lifetime Vygotsky's theories were controversial within the Soviet Union.
The. (ZPD) has been defined as  the distance between the actual developmental level as determined by independent problem solving and the level of potential development as determined through problem solving under adult guidance, or in collaboration with more capable peers  (Vygotsky, 1978, p. 86).ev Vygotsky views interaction with peers as an effective way of developing skills and strategies. He suggests that teachers use cooperative learning exercises where less competent children develop with help from more skillful peers-within the zone of proximal development.
