associated with such products are “low cost,” “locally manufactured,” “durable,” “easily maintained.” They are safely operable by illiterates and not easily counterfeited with inferior products. They are often referred to as “appropriate technology.” These are not trivial requirements, and the engineering design for these products can be extremely challenging. For this reason, they are of specific interest to the academies of sciences of both Nigeria and the United States.

As of 2013, the National Science Education Standards have been replaced by the Next Generation Science Standards (NGSS), available as a print book, free PDF download, and online with our OpenBook platform.
The NGSS offer a detailed description of the key scientific ideas and practices that all students should learn by the time they graduate from high school. The standards are based largely on the 2011 National Research Council report A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas.
