Wind power is capital intensive, but has no fuel costs. The price of wind power is therefore much more stable than the volatile prices of fossil fuel sources. The marginal cost of wind energy once a station is constructed is usually less than 1-cent per kWÂ·h.
The knowledge framework is a tool for analysis. 1  There are five parts to the framework: 2  scope and applications. 3  key concepts and language. 4  methodology. 5  key historical development. 6  links with personal knowledge.
By Derrick Meador. Depth of Knowledge is also referred to as DOK. Depth of Knowledge is the complexity or depth of understanding required to answer or explain an assessment related item. The concept of depth of knowledge was developed through research by Norman L. Webb in the late 1990âs. Webb was a senior research scientist for the Wisconsin Center of Education Research. Webb originally developed depth of knowledge for mathematics and science standards. However, the model has been used in language arts, mathematics, science, and history/social studies. His model has been adopted by more than ten states. Webb identified four distinct depth of knowledge levels. Level 1 includes basic recall of facts, concepts, information, or procedures.
