For almost 5,000 years-from about 3000 BCE to 1500 CE-the prehistoric Indians of the woodland areas of midwestern and southeastern North America fashioned utilitarian and ceremonial objects from shell, stone, metal, wood, and clay. This program discusses the cultural and aesthetic significance of these ancient artifacts. Illustrations accompany the text, which also includes maps showing the Archaic, Woodland, and Mississippian period sites where the pieces were excavated.
Computational thinking (CT) involves a set of problem-solving skills and techniques that software engineers use to write programs that underlie the computer applications you use such as search, email, and maps. However, computational thinking is applicable to nearly any subject. Students who learn computational thinking across the curriculum begin to see a relationship between different subjects as well as between school and life outside of the classroom.
Specific computational thinking techniques include: problem decomposition, pattern recognition, pattern generalization to define abstractions or models, algorithm design, and data analysis and visualization.
