Answer: Africa has the world's oldest record of human technological achievement: the oldest stone tools in the world have been found in eastern Africa, and later evidence for tool production by our hominin ancestors has been found across West, Central, Eastern and Southern Africa.[1] The history of science and technology in Africa since then has, however, received relatively little attention compared to other regions of the world, despite notable African developments in mathematics, metallurgy, architecture, and other fields.

Twelve-year-old Nathaniel was having trouble solving the word problems in his math homework. His dad began reading the problems
Sonbull [250]

This question is missing the options. I've found the complete question online. It is as follows:

Twelve-year-old Nathaniel was having trouble solving the word problems in his math homework. His dad began reading the problems aloud and emphasizing the important information. As Nathaniel started catching on, his dad gradually provided less help for each new problem. This interaction illustrates:

A) Piaget's concept of concrete operational thought.

B) Erikson's concept of industry versus inferiority.

C) Vygotsky's concept of scaffolding.

D) Piaget's concept of conservation.  

Answer:

The correct answer is letter C) Vygotsky's concept of scaffolding.

Explanation:

According to Vygotsky's Zone of Proximal Development, scaffolding is the process in which a supporter helps a learner, but only to a certain extent. As the learner grows more knowledgeable, the supporter gradually withdraws his help, allowing the learner to do things on his own. Eventually, the learner becomes responsible for the outcome of his tasks. That is what Nathaniel's father is doing while helping him with his math homework. He assists Nathaniel, but slowly steps away allowing his son to solve problems on his own as he gains more knowledge.
