Finding out What Parents Want to Know

Every school has some form of reporting to parents, but only a few schools use a system of having parents report to teachers. During the 1954-55 and 1955-56 school years the staff of the Shorewood public schools suggested that an evaluation of the reporting system used in both the elementary and the secondary schools be included as one of the all-faculty workshop problems. Representatives from all grade levels volunteered to serve on a workshop committee to study this problem. During the second year, a group of thirty parents were chosen at random by the principals to serve on a committee to study procedures used in the elementary schools for reporting pupil achievement and progress. A similar group was chosen for the secondary-school level.

Some Problems in the Manufacture of Experimental Gas Turbines

The gas turbine has created new workshop problems arising from the use of special materials and from the complexity of some of its component parts. The construction of experimental sets calls for much improvisation to avoid heavy expenditure on special tools and machines, and the paper gives examples of methods which meet this requirement. Blading for axial turbines and compressors when required only in small numbers, as in the manufacture of experimental sets, is probably the major problem and cannot be met without the provision of some special facilities, the basis of which is usually copy machining. One of the most notable developments has been the use of sheet metal in the gas turbine, not only for the combustion system but also for structural parts, many of which are subject to severe conditions imposed by high temperatures, and fatigue stressing. The highest grade workmanship is essential in this connexion, to ensure reasonable life, free from failure. The special demands of gas-turbine design are constantly giving rise to new manufacturing techniques and the paper deals briefly with some of these, such as those associated with welded rotors and precision forged blading.
