Described are the results of an experimental study of a well developed, turbulent boundary layer on a smooth, flat surface encountering an area of much rougher surface. The roughened area is a strip with its length extending in the direction of the mean flow but of finite width in the surface direction normal to the flow. The resulting three-dimensional flow is found to differ significantly from previously studied cases involving step changes in roughness of infinite extent in the direction normal to the flow. Extensive experiments are reported in a wind tunnel having a length of nearly 100 ft with a boundary layer thickness of the order of 18-20 in. Pitot tube and hot-wire anemometer measurements were made of mean velocity and Reynolds stress quantities throughout the flow field. Secondary flow components were measured by a new x-wire technique.

This paper describes the rationale, direction, and progress of the Integrated System for Workforce Education Curricula (ISWEC), a project sponsored by a 25-state consortium that is designed to accomplish two primary objectives: (1) integration of academic and vocational education in a curriculum framework for grades 9-14 and (2) development of a process through which educators can elaborate upon the framework to adapt it to their schools' needs and strengths. The following topics are discussed: rationale for integration, consensus about education and work; pedagogical advantages to integration; role of standards in the ISWEC project; rationale for a comprehensive curriculum project; purpose and content of an integrated curriculum standard (ICS); process of grouping ICSs into clusters and career majors; role of assessment in the ICS framework; technique for using ICSs to develop curricula; process being used to develop the ICS framework; and relationship between integration and higher-order thinking skills. Contains 13 references. Appended are sample integrated curriculum standards and a list of steps toward integration using work force, academic, and occupational standards. (MN)
