Each One Teach One | Reflection Post

Each One Teach One is an assignment where each student chooses a topic and presents their research to the class. Through these presentations, I learned how much communication has changed through technology and how many everyday tools have shaped the way information is created, shared, and consumed.

My classmates introduced topics such as the history of paper, the invention of CDs, the impact of radio, and the evolution of the pen, showing how innovations across different time periods transformed communication and continue to influence society today.

The history of paper stood out to me the most. Developed in China around 105 CE, paper replaced bamboo and costly silk, made communication more efficient, lowered sharing costs, and expanded literacy, education, and knowledge.

Europe's First Printed Book was the Gutenberg Bible.

I also found it interesting that paper supported the printing revolution. It enabled books, newspapers, and libraries, which helped information reach more people than ever before, even though environmental and misinformation challenges remain today still.

Learning about CDs reminded me how quickly media formats change. Compact discs were developed in the 1970s for music, competed with vinyl records and cassette tapes, and helped create the age of digital media worldwide.

The first commercial CDs and players were released in 1982. People replaced older music collections with CDs, but eventually MP3s and streaming services replaced them, showing that communication technology never stays the same for long.

The timelines of communication are constantly growing.

Radio was another topic that surprised me. Instead of having one clear inventor, several people reached similar breakthroughs around the same time. Historians still debate who deserves credit, making its history complex and highly contested.

The history of the pen showed how everyday tools evolve. I was especially interested in the development of the ballpoint pen, whose patent appeared in 1888, improvements came in the 1930s, and popularity grew during the 1940s. Ancient reed pens, quill pens, dip pens, and fountain pens eventually led to modern designs. 

Small improvements made writing easier and faster over many centuries, showing how technologies have and will continue to evolve and reshape communication.

AI Disclosure: AI was not used in the research and information for this blog post. All information came from notes that I took while watching my classmates present their Each One Teach One research projects. I then prompted Microsoft Copilot Pro to help shape my notes into a blog post of between 300 and 350 words written in a smooth professional style. I then added appropriate images and captions to help break up the type and give the post a more professional look.
