Application of Airborne Television to Public Education

In an effort to bring the advantages of television teaching to the maximum number of public schools, particularly those in hilly or sparsely settled parts of the country, a project has been launched to provide airborne transmission of six simultaneous school lesson program. Coverage area is increased approximately 20 to 1 by this means compared to the usual ground station coverage. Airborne transmission is the most economical and effective use of the available (UHF) frequency spectrum. Results already established regarding the use of television as a teaching medium are projected via an airplane flying at 23,000 feet altitude over an area covering parts of six Midwestern States. Educational advantages and problems inherent in ground station TV are intensified in this larger coverage area, and planning is governed accordingly. Technical problems include multiplex transmission of six lessons simultaneously, keeping the airplane on station, accommodation of transmitting equipment in the airplane, and determination of bandwidth for optimum picture quality.     

Formula for Uncertainty

How LEAs are measuring and allocating resources for special educational needs varies widely. Yet their formulae for doing so are likely to make the difference between enabling pupils with special needs to progress in their learning and, conversely, reducing the support they may need.
