These diagrams or triangle diagrams are often used after webs, especially with science topics, to illustrate a hierarchy. Most students need help in seeing possible connections between categories or sets of information in a web. Their webs may look like spokes on a wheel hub, which tend to sprout at the tips. This usually represents broad categories tipped by specific examples. With notebooks open during the reading, students diagram the emerging plot as a web.
Small groups compare, then feed into a class web of the plot.
Done in either the library setting or the classroom, the educator helps students note the cross-connections. Students then read and web one on their own, and follow with a group web. This leads to understanding how computers work and how to create a branching program. Meaningful learning and expansion of ideas over time, as made obvious by constructed webs, contributes to sustained intrinsic motivation. The third web can be used as a final test, an assessment of factual or conceptual attainment.
