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.

Bamboo water wheel irrigating rice fields at Mai Chau

Sizes available: 1024×683 | 600×400

A bamboo water wheel is being used to irrigate rice fields at Mai Chau. The current of the stream turns the large wheel. Curved bamboo slats set at the circumference of the wheel lift water from the stream and, as the wheel turns, dump water into a bamboo pipe that leads to another field needing water.

Wet-rice farming requires that plants stand in water during early stages of their growth. The water then must be drained away before the rice fully ripens for harvesting. Bamboo wheels such as the one shown here aid this process of water management in places where the slope of the land does not allow good water movement to occur only with gravity and dykes that can be opened and closed for drainage between adjacent fields.
