Chapter 14: Supporting Details

Types of Supporting Details 

We have seen how supporting details are in paragraphs to support, explain, and clarify the main idea. Now we will learn about the 2 types of supporting details. 

Major Supporting Details (Major Details)

Example

Social Media’s Effects on Communication

Social media has had a profound impact on communication. Platforms like Instagram, TikTok, and Facebook have revolutionized the way people connect with friends and family. Users can share photos, videos, and thoughts instantly with a global audience. Additionally, social media has become a powerful tool for businesses to reach consumers and build brand loyalty. Paid influencers, as well as traditional advertisements, are able to target consumers through analytics. Furthermore, these platforms have facilitated the rise of social movements and activism, allowing people to organize and mobilize around shared causes. The “me too” movement is just one of many started and carried out online through social media.

Mapping and Outlining

How can they help us?

Mapping

Concept mapping is the visual organization of ideas. These maps, or webs, illustrate the information in levels, with the topic or main idea usually located in the center or at the top of the web, and details branching off from there.  As the map spreads out, the details get more and more specific. 

Image shows a hierarchy in which the main idea is supported by major details, which are then supported by minor details

Outlining

Outlining is another method of organizing information in a hierarchy.  It involves breaking down a topic into main ideas, major details, minor details, and often even further. 

This outline shows the relationship between a paragraph’s main idea and its major and minor supporting details. In an outline, as information gets more specific, it gets indented, or “pushed in.”  Each level of information has a unique symbol. 

I. Main Idea

A.  Major Supporting Detail 

1.   Minor Supporting Detail

2.   Minor Supporting Detail

B.  Major Supporting Detail

1.   Minor Supporting Detail

2.   Minor Supporting Detail

3.   Minor Supporting Detail

C.  Major Supporting Detail
