K-12 Teaching and Learning From the UNC School of Education

Important Announcement about Online Courses and LEARN NC.

Important Message about LEARN NC

LEARN NC is evaluating its role in the current online education environment as it relates directly to the mission of UNC-Chapel Hill School of Education (UNC-CH SOE). We plan to look at our ability to facilitate the transmission of the best research coming out of UNC-CH SOE and other campus partners to support classroom teachers across North Carolina. We will begin by evaluating our existing faculty and student involvement with various NC public schools to determine what might be useful to share with you.

Don’t worry! The lesson plans, articles, and textbooks you use and love aren’t going away. They are simply being moved into the new LEARN NC Digital Archive. While we are moving away from a focus on publishing, we know it’s important that educators have access to these kinds of resources. These resources will be preserved on our website for the foreseeable future. That said, we’re directing our resources into our newest efforts, so we won’t be adding to the archive or updating its contents. This means that as the North Carolina Standard Course of Study changes in the future, we won’t be re-aligning resources. Our full-text and tag searches should make it possible for you to find exactly what you need, regardless of standards alignment.

Carved stone wall in Teotihuacan, Mexico

Size: 1024×709

A carved stone animal head emerges from a stone wall. The head emerges from a base that is similar to a flower. A metal rod is supporting the head.

Teotihuacan is the name of a Mesoamerican indigenous civilization and its grandest city, once the largest city in Mexico. The Teotihuacan people predated the Maya by over five hundred years, and the Aztec by more than a thousand years. The civilization of Teotihuacan reached its height in the 1st century CE (AD) when the huge pyramid to the sun was built. The estimated population of the city at its largest varies from 150,000 to 250,000. Artisans of the city are known for the sweeping grandeur of the buildings they left behind, and numerous artifacts made from obsidian, a black volcanic rock indigenous to the region.

The reason for the decline of the city and its civilization after 450 CE (AD) is unknown. Some archaeologists hypothesize that climate change and severe droughts led to internal unrest that may have caused the destruction of the city. Today, Teotihuacan is a popular tourist destination replete with museums and ongoing archaeological investigation.
